Several tricks to solve the problem of low powder output efficiency of feldspar Raymond mill
2020-05-08
Raymond mill is a typical equipment widely used in limestone, dolomite, gypsum, feldspar and other non-metallic ore processing and production. Because of its high output efficiency, large output, energy saving and environmental protection, it is greatly loved by the milling industry. As a high-tech manufacturer specializing in the production of feldspar Raymond mills, Shanghai Clirik Machinery Co., Ltd. has extensive experience in the production of feldspar milling equipment, and can provide constructive solutions for the low efficiency of Raymond mill powder production. Opinions and suggestions, I hope to help milling enterprises.


1. Reasonably select the rotation speed of the host machine and improve the grinding force of the host machine


Because the grinding force mainly comes from the centrifugal force of the grinding roller, the speed of the host machine directly affects the size of the grinding force. The low speed of the driving shaft may be one of the reasons for the low powder output rate. Considering the load-bearing capacity of the host motor, it is a factor to improve the production efficiency of the pendulum mill. Increase the kinetic energy of the mill, adjust the belt or replace it with a new one.


2. Reasonably adjust the air pressure and air volume of the blower


Due to the physical properties and chemical composition of various non-metallic mineral raw materials, there are huge differences. When adjusting the wind pressure and air volume, the relatively dense minerals (such as barite, iron ore, etc.) should be smaller and made Adjust appropriately.
 

3. Reasonable design of blade device and selection of wear-resistant materials for grinding rollers and grinding rings


The wear of blades, grinding rollers, grinding rings and other main grinding consumables will seriously affect the powder yield. Choose wear-resistant parts with high wear-resistant materials, such as high-chromium cast iron. The shovel can't shovel the material, the wear of the grinding roller and the grinding ring is not serious enough to cause a good grinding effect, resulting in a low powder processing rate, and the wearing parts should be replaced in time after wear.
 

4. Do a good job of equipment lubrication


Another reason that may affect the rotation speed of the main machine of the mill is that the grinding teeth become blunt. Therefore, it is necessary to check the transmission parts such as grinding teeth from time to time and prepare for lubrication and replacement.
 

5. Dredge the pipeline and make a good seal


The conveying duct of the mill is blocked, and the powder cannot be transported normally, which will cause the problem of low powder output or even no powder. Solve the problem that the machine needs to be shut down to clear the material in the pipeline and restart the material.
 

6. Pay attention to the humidity, viscosity, hardness, etc. of the material


The performance of the equipment itself is the main factor that determines the production efficiency, but the nature of the material, such as powder humidity, viscosity, hardness, and output particle size requirements, will also affect the powder output rate. With reference to the specifications and operating instructions of the equipment, the best production results can only be achieved by operating under the corresponding requirements.

The above suggestions are some of the major tricks to improve the low powder output efficiency of the feldspar Raymond mill. I hope to help and inspire friends who have needs.
