How to improve the production efficiency of Raymond mill

Raymond mills are popular because of their low price and high output. But after using it for a while, these advantages are gone. The Raymond mill has a lower and lower powder rate, which seriously affects the company's efficiency. How to solve these problems has caused many companies to have a headache. What should be done? We have compiled some ways to increase the powder extraction rate and production efficiency of Raymond Mill.

1. Reasonably select the main engine speed and improve the grinding force of the main machine. Since the grinding force is mainly derived from the centrifugal force of the grinding roller, the height of the main engine directly affects the grinding force. The low speed of the drive shaft may be one of the reasons for the low powder output rate. If the power is insufficient, the drive belt is too loose or the wear is severe, the drive shaft speed will be unstable and decelerated. Recommendation: Considering the load carrying capacity of the main motor is a factor in improving the production efficiency of the mill. Increase the kinetic energy of the mill, adjust the belt or replace it.

2. Reasonable adjustment of air pressure and air volume of air blowers Due to the physical properties of various non-metallic mineral raw materials, there are huge differences in chemical composition. For minerals with lower density such as graphite and gypsum, the relative density should be adjusted when adjusting wind pressure and air volume. Large minerals (such as barite, iron ore, etc.) should be small and adjusted properly. If they are too large, the coarse particles will not be well graded and mixed into the finished product when they are sieved by a classifier. Unqualified products; if it is too small, the main unit is prone to blockage, which makes the machine unable to operate normally.

3. Reasonable design of the blade device and selection of the wear-resistant material of the grinding roller ring The blade device is an important device for directly shoveling the material between the grinding roller and the grinding ring. After technical development and improvement, the blade design of Raymond mill It is reasonable to shovel and allow the material to be fully ground between the grinding roller and the grinding ring. Scraper, grinding roller, grinding ring and other major grinding consumables will seriously affect the rate of powder extraction. It is necessary to choose wear-resistant parts with high wear-resistant materials, such as high-chromium cast iron. The blade can not afford the material, the wear of the grinding roller ring is not good, and the grinding effect is low, and the powder processing rate is low, and the wearing parts should be replaced in time after being worn.

4, do a good job of equipment lubrication Another reason for the mill's main engine speed may be due to the blunt grinding teeth, so you need to check the gears and other transmission parts from time to time, to prepare for lubrication.

5, dredge the pipeline, do a good job of blocking the conveying duct of the sealing mill, resulting in the powder can not be transported normally, which will cause the powder production to be low or even no powder. When the treatment is needed, it is necessary to stop the material in the pipeline and restart the feeding. . Suggestion: The ultrafine powder contained in the material has a large agglomeration effect, and the loose specific gravity is small, and the volume is large (the 800-mesh product with the same weight is nearly twice as large as the 325 mesh product), and it is easy to stick to the pipe wall and the material. On the wall of the warehouse, it is not easy to fall, so the inner wall of the pipe and silo should be as smooth as possible. It is best to lining the galvanized or stainless steel plate. The discharge taper of the silo should be as small as possible. It is best to add a wall vibrator. In addition to clogging, the sealing has an effect. The poor sealing of the pipe will result in increased dust, negative pressure imbalance, low powder delivery rate, and the sealing pipe must be in place before production. Suggestion: The powder locker of the Raymond mill production line is not adjusted to the correct state, resulting in poor sealing, powder suction and other phenomena, ensuring that the locker, return air valve and other valves on the pipeline should be in good condition. Working status.

6, pay attention to the material's humidity, viscosity, hardness and other equipment itself is the main factor determining the level of production efficiency, but the nature of the material, such as powder moisture, viscosity, hardness, discharge particle size requirements, etc., will also affect the rate of flour . Refer to the specifications and operating instructions of the equipment and operate under the corresponding requirements to achieve the best production results. Reasonable use of equipment, daily maintenance and maintenance, in order to maximize the life of Raymond mill, to maximize performance and create maximum efficiency.
