Hi Wray. Thank you for your question.

Low end Raymond Mill will cause bad effect for the whole production and increase running costs. And let’s talk about the disadvantages of low end Raymond Mill.

Low end Raymond Mill will produce powder with low fineness, and the size is often below 500 mesh, which only occupies the lower end of the powder application market, and do not adapt to the trend of fine development of powder industry in the future.

Besides, low end Raymond Mill takes disadvantages of high mechanical failure rate, large power consumption, loud noise and large emission pollution.

Then, its system efficiency is low, and the separation efficiency of collection system is not ideal, and a large number of fine powder can not be collected effectively. It will cause powder waste because of repetitive cycle in Raymond Mill.

In addition, there is a design mistake of main engine’s air duct. The larger particles entering grinding area and no crushed materials will be often thrown into the tail of the worm box, and continue to extend forward, so that the air volume is gradually reduced, and it is easy to cause traffic jam, no powder or less powder, which affects the capacity of the set of Raymond mill.
