Raymond mill dust removal is a protective measure, dust bag is raymond mill supporting facilities, is a traditional dust removal equipment. Many users have found that cloth bags are more easily damaged, to the normal operation of the equipment has brought no small impact. Therefore, the current pulse dust removal equipment has gradually replaced the cloth dust bag dust bag is used to filter dust or air flow control device, which in the course of its use is not easy to wear parts. However, the dust bag also has a useful life, will wear. Lead Raymond wear dust bag wear reasons, mainly in the following two points:

1, if the Raymond grinding process produces a very fluid and highly abrasive dust, then the direct wear dust bag, reducing the service life, such as common aluminum powder, silicon powder and toner.

2, there is also a kind of dust on the dust bag wear is also very serious, that is charged with dust or hot particles. This is because chemical fiber filter is usually easy to charge, if the dust is very easy to produce sparks while charging, it is easy to damage the dust bag.

Raymond mill mainly by the Raymond mill host, Raymond mill and Raymond mill powder collector composed of three parts. Which collectors in the entire system mainly plays the role of powder and dust collection.

Raymond mill powder collector thickness varies by model, due to different manufacturers, different manufacturers of different models of the thickness of the powder collector is not the same. Even the same model, different manufacturers use the collector thickness is not the same. The thickness of the collector will also have a significant impact on the use of the Raymond mill, the main effect being the repair rate of the Raymond mill. If the dust collector thickness of the Raymond mill is too thin and the material of the Raymond mill is too hard, Raymond mill powder collector is easy to wear through. If the Raymond mill collects dust, it needs to be repaired or replaced, which affects the normal production of the Raymond mill and increases the maintenance costs for the Raymond mill.

Vertical roller mill (referred to as vertical mill) and Raymond mill grinding mechanism similar to all belong to the rolling crush, which is destined to produce less than the amount of fine powder per unit time. As the roller pressure is used hydraulic method, the roller pressure roller material greater, so the grinding efficiency is much better than the Raymond mill. Initially, vertical mill are two roller structure, mainly used for the production of 400 meals the following meal.

In order to improve the content of fine powder per unit time, three-roll vertical mill was developed later, and the content of fine powder has been greatly improved, but generally, the products below 1000 heads are still mainly produced. Later, some people on the upper classifier has been transformed, can be directly produced 1250 mesh powder. The use of the Raymond mill out of the 600 head -1000 head products, the other with ultra-fine grading machine for second grading, can produce more than 1250 heads of products. At the same time, the equipment system investment cost is too high.

Vertical mill R & D and production of high technical requirements, China's relevant research institutes in the 1980s proposed to vigorously promote the legislation in the cement industry legislation, and when there are some manufacturers have introduced their own vertical mill products. However, at the time of the limited research and development level, vertical mill products at this time had unavoidable technical defects. Therefore, many cement manufacturers finally switched to ball mill again. In recent years, with the R & D and development of milling machinery increased dramatically, vertical mill technology of foreign mill manufacturers has matured, vertical mill product technology advantages have become increasingly prominent. In this situation, the domestic manufacturers of milling machines to learn from the successful experience of foreign countries for major technological reforms, but also have re-launched with their own patented technology vertical mill products, and gradually accepted by the domestic cement, electric power, chemical industry , Become the preferred equipment grinding industry.

raymond mill production capacity and processing of the final product fineness and analysis of the machine speed has a direct relationship.

Finished powder thickness and speed of the analyzer Raymond grinding debugging part, the first is the boot sequence, boot after the observation of the host is normal, and then from the material feeding mouth, then check the fineness of the powder after the material compliance, through the sample Sieve to test the powder, if the fineness of the powder is too coarse on the need to adjust the speed of the analyzer, the faster the analyzer speed, Raymond mill will be the more coarse powder, the slower the speed of the analyzer, the thunder Wear the mill will be finer powder. In addition to adjust the speed of the analysis machine, but also to adjust the size of the fan air volume, the greater the air volume, Raymond mill will be the more coarse powder, the smaller the air volume, Raymond mill powder will be finer . The best analyzer speed and the best position of the air volume vary according to the material, depending on the fineness of the material.

When you adjust the fineness of a powder, the best fixed speed is: colleagues to meet the fineness, open to the maximum air volume, so as to ensure that the production of the Raymond mill powder to produce the maximum production, and then for the Raymond Mill Users create greater value.

Everyone in the use of raymond mill, certainly know to maintain the grinding ring, roller, blade, and these materials directly contact with the wearing parts, usually ignore other factors, the use of mill friends know, the voltage The use of equipment is also affected, then the mine work when the voltage instability will be how? What's wrong? Let's take a look at it.

What happens when it works when the voltage is unstable? What's wrong?

When we use Raymond Mill, the voltage suddenly affects the production and is very easy to burn the motor! This point we must pay attention, do not ignore the impact of voltage on the equipment.

First, it is mainly at work with a constant voltage to drive the roller to continue to rotate, and repeatedly squeeze the grinding ring to grind the material, the final powder out of the material will be evenly finely, if the voltage Suddenly large and small, will affect the finished product size, resulting in rework phenomenon;

Second, the voltage instability, will lead to blower wind pressure when large and small, resulting in grinding chamber pressure instability, the voltage becomes smaller when the mill pressure will become smaller, in which case the grinding material will not be easy to send To the analysis machine, resulting in a large number of grinding room accumulation of materials, causing ventilation pipe blockage;

What conditions will lead to raymond mill voltage instability

First, the power cord contact bad (transformers, wattens, circuit breakers, sockets and other parts of the joints);

Second, the output power is unstable, resulting in voltage instability;

Third, the power supply zero line resistance is too large, poor contact;

Fourth, the equipment itself: mechanical part of the transport is not flexible, there are plugs caused by functional instability, causing current changes, voltage instability;

What happens when the voltage is unstable when the Raymond Mill is working? What's wrong? Now we all know it, if you encounter voltage instability, be sure to carefully check the line is the reason for the equipment or equipment to find out the reasons for the deal. In addition, we can also use some regulators to regulate the voltage to ensure safe and safe production of voltage.
