Raymond mill is one of the more common grinding equipment, can be used for Mohs hardness is not greater than 9.3, humidity below 6% of the non-flammable and explosive mineral, chemical, construction and other industries 280 kinds of materials for high-fine powder processing. There is a saying in the powder industry that "three parts process, seven parts operation", which directly points out the importance of operation technology and method of milling production. For many users, the new Raymond mill how to use correctly is a very important issue, it is not only about the improvement of production efficiency, but also with the operator's personal safety is closely related. Here is an introduction to the correct use of Raymond mill.

1, the precautions before starting

Before starting the Raymond mill, you must check whether all the access doors are tightly closed, with a jaw crusher and elevator milling production line, to check whether the crusher jaw clearance is in line with the size of the feed size, adjust the speed of the analyser should be up to approximate the finished product size requirements, adjust the fan to maintain the appropriate air volume.

2、Opening sequence

(1) Firstly, switch on the bucket elevator to achieve continuous and even conveying of materials;

(2) Secondly, wait until there are materials in the material warehouse, open the analyser;

(3) Again, start the blower when no load, wait until normal operation and then load materials;

(4) Finally, start the host of Raymond mill, start the electromagnetic vibrating feeder at the moment of starting the host. At this point, the Raymond mill began to work normally.

3、Precautions in operation

(1) Raymond mill in normal operation is not allowed to refuel, to ensure production safety;

(2) Raymond mill in any part of the occurrence of abnormal noise, or a sudden increase in the load, should be immediately shut down to check, troubleshooting, to avoid major accidents;

(3) When you start the machine again, you must take out all the residual material in the machine, otherwise the current will be too large when you start the machine, which will affect the startup, and in serious cases, you may even burn down the equipment.

4、Shutdown sequence

(1) Shut down the feeder first to stop feeding;

(2) Stop the main machine after the feeder stops for about one minute;

(3) Stop the blower after the residual material is cleaned up;

(4) The correct stopping order is: feeder - host - blower - analyser;

(5) It should be noted that when the elevator conveys materials to the bin after a certain amount, first stop the crusher and then stop the elevator, the amount of material storage as needed.
