In several industrial processes, there is a generation of dust and some debris. As a result, equipment is needed to capture them. The most obvious solution is to place a machine that performs this absorption close to the emission source, but the question that arises here is: what should be taken into account when talking about industrial dust extractors? The truth is that there are several types of equipment available in the market. The dust collector, as its name suggests, serves to capture dust. But how does this happen? To summarize how it functions, the dirty air enters the collector, passes through the filter media that retain the dust, and as a result, the clean air is released into the environment. It sounds very simple, but in practice, it is not so easy. There are several ways to carry out this process with very different operating costs. One of the main costs involved in this process is the consumption of electricity. Inadequate filtering areas, low permeability filter media, and inefficient filter cleaning systems can cause very significant energy waste. The dimensioning of a dust collector is something complex that must take into account several factors. Some examples are the granulometry of the generated dust, density, safety aspects (risk of explosion, fire), and the toxicity of the handled product. Surveys must also be carried out of the pressure losses existing before the dust collector (ducts, curves, restrictions, etc.). Our technical team evaluates all these issues to make the correct specification for each case, optimizing the collector performance to the maximum. But on top of all that, in 2011 we developed a patent-pending system that alters the airflow in the CMV® dust collector. We are the only ones working with a downward airflow and we will explain why this is a great advantage. See the difference in the schematic illustrated below. In the CMV® system, the dust generated after cleaning falls directly into the disposal. In the conventional one, it returns to the filter, making cleaning difficult. The CMV® dust extractor, BMF model, can be used to capture welding fumes, for blasting, laser/plasma, powder painting, crushing, and for the pharmaceutical industry, etc. This system greatly improves the cleaning efficiency of the filter media, enabling the use of lower fan pressures when compared to conventional systems. It provides great energy savings due to lower fan power, lower noise level, and longer filter media life. Purchase a dust extractor with the technology that matches your company, with low maintenance costs, the best performance, and, above all, meets all the required standards.

Shot peening stands out as a pivotal process in enhancing material durability and performance across various industrial sectors. Unlike conventional blasting techniques that may employ both spherical and angular abrasives, shot peening exclusively utilizes spherical abrasives, showcasing a refined level of precision and control. The mechanism behind shot peening involves the forceful impact of granules on the metal, inducing plastic deformation and compressive stress on the surface. This compression effectively counters any tensile stress, mitigating the risk of stress-induced cracking and enhancing the overall structural integrity of the component. Studies have shown that shot peening can lead to remarkable improvements in component lifespan, with some reports indicating an increase of up to 1,300% in service life. By reducing tensile stress levels on the surface, shot peening significantly diminishes the likelihood of equipment fatigue, potentially extending operational longevity by as much as 560%. Critical machinery parts such as gearboxes, crankshafts, blast wheel blades, and other components experience enhanced durability and reliability in service. Shot peening demands meticulous control over granule size distribution, ensuring optimal surface modification and performance. Advanced shot peening systems feature real-time monitoring and adjustment of abrasive volume and velocity, ensuring consistent and effective surface treatment. Additionally, precise control over blasting angles and distances enables tailored surface modifications to meet specific requirements. The significance of shot peening extends across a diverse range of industries, including aerospace, automotive, and metalworking. In aerospace, shot peening enhances the durability of critical components such as turbine parts and landing gear. In the automotive sector, shot peening contributes to improved performance and longevity in components including springs, gears, and suspension arms. In metalworking, shot peening plays a vital role in enhancing the durability and performance of cutting tools, stamping dies, and forged components. At CMV®, we specialize in delivering cutting-edge shot peening solutions tailored to meet the demands of modern industry. Our state-of-the-art equipment ensures superior performance, reliability, and cost-effectiveness, empowering businesses to achieve unparalleled levels of productivity and efficiency. Reach out to our team of experts today to explore how CMV® can elevate your operations to new heights of excellence.

Although the shot peening and the shot blasting processes are different, both blasting systems work towards finishing metal parts. We can say that metal parts aren't ready to use in an industrial field without previous treatment. They often need cleaning so that later on, they can have a better finish, like a painting process, powder coating, etc. The blasting process is the better fit to finish metal surfaces and pieces. Still, to understand which of these processes makes more sense to your company, we listed below the main differences between shot peening and shot blasting. You will see in this publication: Main differences between shot peening machine and shot blasting How shot blasting works How shot peening works Which one is better? 1. Main differences between shot peening machine and shot blasting Although shot peening and shot blasting have the same basic principle, "shooting" a material (media) against a surface, the results are very different. We listed some main differences between both systems: • The angle of attack, the abrasive (spheres) release position against the workpiece. • The volume of abrasive launched. • Abrasive launching speed. • Abrasive rating (size, roundness). 2. How shot blasting works Conventional blasting works only with spherical and angular media. Depending on the application, the blasting machine will work by a wheel blasting or air blasting system. Summing up, on the wheel blasting machines, the abrasive is thrown through the centrifugal force that is created by the blast wheel. On the other hand, on compressed air blasting machines, the media is pressurized or sucked into a tank and then expelled through one or several nozzles. 3. How shot peening works Shot peening uses only spherical abrasives and has several controls, way more sophisticated and restricted than shot blasting. See some main benefits provided by using a shot peening machine: • Improves the resistance to mechanical and thermal fatigues. • Enhances the corrosion and friction resistance. • Allows to reduce the size and weight without compromising the mechanical resistance. • Eliminates the directional risk of machining or micro-cracks, inhibiting crack propagation. • Forming (deforming or straightening workpieces, also known as peen forming). One of the primary uses of shot peening is in the aerospace industry because many aircraft components are treated, including various turbine parts and structural and landing gear. The shot peening machines are a good fit in the metalworking and automotive industry. 4. Which one is better? It is wrong to say that one system is better than another because it depends on the application. We can affirm that for pieces that demand a precise finishing or a very high material resistance, the shot peening is strongly indicated and evidentially a better fit. But besides all the explanations, the truth is that you don't need to know if the shot blasting or shot peening process is a better fit for your company. Your company can count on our free technical consulting to tell you which blasting machine is a better fit to increase your production and achieve better blasting results.

In the past, a hammer was used to increase the hardness of gold. As new technologies came and manufacturing evolved, shot peening gained strength and became a trend. The result generated by shot peening is an increase in the parts' lifespan and capacity. In addition, it improves the metallurgical characteristics, eliminates cracks, and brings more resistance to friction. Below we enumerated the main questions about shot peening: 1. How is shot peening done? 2. Where shot peening can be applied. 3. Difference between shot peening and traditional blasting. 1. How is shot peening done? Shot peening is a solution for intensive use of industrial components under mechanical or thermal fatigue. It is a high-technology process that uses blasting to clean up the surface. In this process, the residual tension of parts switches to a residual compression effort. Shot peening can be used on treatment surfaces such as grinding, milling, folding or thermal treatment. It is commonly used in the manufacturing, automotive, and aerospace industries. Shot peening is similar to blasting, except it works with plasticity instead of abrasion. Each particle performs like a "hammer ball," which means that less material is removed in the process. 2. Where shot peening can be applied. • Aerospace industry: it is the one that proportionally most uses shot peening. An infinity of aircraft components is treated with this method. The blast wheel, the structural, and the landing gear components are among them. • Automotive industry: springs, gears, torsion bars, connecting rods, crankshafts, axles, and suspension arms. • Metal-mechanical industry: cutting tools, stamping, forging (mainly cold). 3. Difference between shot peening and traditional blasting. The traditional blasting works with spherical and angular media. Shot peening uses only spherical abrasives and has several controls, which are way more sophisticated and restricted than conventional blasting. See some examples: • Particle size control. • Spherical control (disposal). • Real-time monitoring and correction of the volume of abrasive used. • Real-time monitoring and correction of abrasive speed. • Control of blasting angles and distance.

Several manufacturers say the water blasting machine is more eco-friendly than the others, but this is not an absolute truth, and we will explain the reasons. See the topics we will discuss in this publication: How the water blasting works and why it is not the more eco-friendly machine Which blasting machine is more sustainable What blasting machine makes more sense to my company? 1. How the water blasting works and why it is not the more eco-friendly machine Let's first understand how the water blasting works. The wet blasting works with water and can perform blasting, washing, and drying operations. The main argument for using a water blasting machine is that it does not produce dust. In this view, if it does not "pollute," it is more sustainable. It is true that the water blasting generates less dust and is very attractive since it is unnecessary to envelop the place, which can often be time-consuming and costly. On the other hand, the cost of maintaining this equipment is much higher than similar ones because the water blasting machine does not allow abrasive recycling. Once the abrasive is used in operation, it is lost, which means that you cannot reuse the primary input of the equipment. Making an analogy, let's imagine that you own a car. This car is ​​hybrid and can be used in any terrain, but it uses 300x more fuel than similar ones. It sounds like an exaggeration, but it's a reality. But that doesn't mean water blasting should never be an option. On the contrary, there are many cases where this machine is recommended. One of them is in situations where the wrapping is very complicated, such as rough terrain. The water blasting is also more appropriate when treating a thin sheet, such as a car's bodywork. It proves to be the best option in this case because if it is well adjusted, it will not deform the blasted part—a common fact in dry blasting. Another factor that is essential to know if you are considering water blasting for your company is the more water this machine uses, the less productive it is. Since water works as a friction reducer, the roughness is reduced at a high volume. Water blasting machines that work with a smaller volume of water operate with abrasive and inject water right after the abrasive dosing valve leaves, moistening the abrasive just enough not to generate dust - a system used by CMV®. 2. Which blasting machine is more sustainable Suppose the blasting operation takes place in a blast room or even in an open area that has been enveloped, using an abrasive recycling system to prevent the abrasive from escaping. In that case, the dry blasting is a much more economical and ecological solution for the following reasons: There is no water consumption. Higher productivity rate due to lower energy consumption. It allows the recycling of the abrasive, which is not possible in the water blasting. In water blasting, grit is not commonly used, and besides that, it only uses the abrasive once. In contrast, dry blasting allows the reuse of grit up to 300 times. Dry blasting is even more advantageous because it can be associated with a portable abrasive recycling system, allowing field applications to be carried out. A fact that is very common in the North American market. 3. What blasting machine makes more sense to my company? Which blast equipment is best? Which uses less energy? The truth is that it depends on the application. For example, many consumers ask us for a quote for a blast room or an automatic blasting machine. When we see the company's activity and use, we realize and recommend a different purchase because CMV® always prioritizes optimizing customers' resources. To recommend a shot blasting machine, we take into account three main factors: How many pieces need to be treated per day (volume) What kind of material will receive the treatment What are the dimensions of these pieces? If you are curious to know which shot blasting machine is best suited for your activity, please contact us. Our technical team will analyze your situation and indicate which blasting machine is most appropriate without cost or commitment.

and how you can benefit from it! If you want to maximize your efficiency in blasting operations, then you need to know about the abrasive recycling system. This machine removes contaminants from abrasives before they are used, preventing clogging and other problems. This post will explain how the abrasive recycling system works and how it can benefit your business. How does the abrasive separator work? Extremely efficient and precise, far superior to rotary sieve separators (which we used previously), the new CMV® abrasive separator is easy to regulate, in addition to being practically maintenance-free, thus obtaining a lower operating cost due to better utilization of the abrasive as the lower cost of maintenance. It receives the abrasive from the bucket elevator and regulates its flow through a hatch on its upper part, distributing the abrasive extremely evenly over the fins of the air washing system. The air current produced by the exhaust system, which has an adjustable flow, passes through the washing system fins, taking with it dust and other residues and the fine abrasive that is unsuitable for use. The abrasive free of these impurities will be conveyed to the vibrating screen. Benefits of the CMV® abrasive separator The main advantage of the CMV® abrasive recycling system is that it provides a significantly reduced operating cost for the company, better use of the abrasive, and much fewer maintenance costs. Aiming to make better use of our customers' space, we have developed a very robust portable abrasive recycling system with the same working capacity as the others. We have this equipment in stationary and mobile versions. We have models with a capacity starting in 74 gallons. Talk to our sales team so they can indicate which model is best suited for your company.

The fundamental principle behind an overhead shot blasting machine is its ability to suspend the part to be treated on a hanger, transporting it into the machine's interior for the blasting process. Typically, these machines are automatic or semi-automatic. However, what sets CMV® overhead shot blasting machines apart is their superiority over competitors. In this post, we'll delve into the reasons behind this significant difference. Many manufacturers of overhead blast machines face challenges in ensuring all faces of the pieces, depending on their geometry, are exposed to the blast wheel fans. To address this, they incorporate a movement known as "oscillation," where the part stops at different locations within the blasting chamber. This maneuver aims to ensure that the entire surface of the part is reached by the fan of abrasive released by the blast wheel. Here's how it works on a competitor's hook-blasting machine: The image shows the first, second, and third stops in order. However, this movement requires a larger space in the working chamber, resulting in a displacement area. Moreover, despite oscillation, the blasting time remains longer compared to CMV® machines. Instead of remaining stationary, the part stops at three different positions, significantly extending the work time. The good news is that such movement is unnecessary for a CMV® overhead shot blast machine. This unnecessary movement is eliminated thanks to the innovative design of the CMV® blast wheel, which utilizes a right/left blade. This patented blast wheel generates two fans of abrasive instead of one, as seen in the image below: Due to its revolutionary design, the CMV® blast wheel can achieve up to 100% higher productivity than conventional blast wheels. In many cases, it's feasible to replace blast wheels from other manufacturers with CMV® ones, ensuring uniform blasting of the part at a much lower cost per blasted piece. It's crucial to emphasize the significant savings per blasted piece achieved with CMV® machines. By reducing blasting time, energy consumption, shot usage, and wear on machine components are all minimized. At CMV®, we're committed to optimizing our customers' resources with our blast machines.
