Raymond mill is an important grinding equipment for processing stone powder. It can process many types of materials, so there are clear requirements for the use of raw materials, for example, for particle size, material hardness, humidity, processing particle size (between 15mm-35mm), etc., which also improves the grinding efficiency of the Raymond mill. Let's see how Raymond mills act accordingly in production.

The working principle of Raymond mill

The crushed materials are continuously uniformly and quantitatively fed into the main machine grinding chamber for grinding. The ground powder is taken away by the airflow of the fan and classified by the analyzer. The fineness of the powder enters the cyclone collector through the pipe with the airflow. Inside, it is separated and collected, and then discharged through the powder pipe to become the finished powder. If the fineness is unqualified, it needs to be recycled and ground until it is qualified.

Structural characteristics of Raymond mill

1. High efficiency and precision classifier, unique airtightness, which canensure the quality of end products.

2. The wear-resistant volute can effectively improve the material liquidity, decrease the air volume loss and avoid air energy loss.

3. The bevel gear overall dive can achieve higher transmission efficiency, easy to install and adjust, long service life and lower cost.

4. Inner thin oil lubrication system can realize lubrication between main bearing and drive bearing without any additional lubrication pump, easy to maintenance.

5. The curved surface shovel with split design, only the blade to be replaced during maintenance, thus the shovel has long service life.

6. The isolated cyclone collector can effectively improving the classifying efficiency and accuracy. The reasons for the reduction of the grinding efficiency of the Raymond mill

1. The powder locker is not tightly sealed. In the powder milling process, if the powder locker's sealing work is not in place, reverse powder absorption will happen, resulting in no powder or less powder, so the seal of the powder locker should be checked regularly and the degree of sealing should be adjusted.

2. The analysis machine is not working. The analyzer is responsible for analyzing the size of the finished powder, whether it meets the standard of the finished product, whether it needs to be sanded again, etc. When the blade of the analyzer is severely worn, it will not play the role of classification, which will cause the powder to be too coarse or too fine. In this case, a new blade must be replaced.

3. The fan is not adjusted properly. If the air volume of the fan is not adjusted properly, too much air volume will cause the powder output of the mill to be too thick. If the air volume is too small, the powder output will be too fine. If there is no abnormality in other conditions, the air volume of the fan should be adjusted to correct the powder particle size.

4. The blade is malfunctioning. The shovel blade is responsible for shoveling the material. When the shovel blade is used for a period of time or the quality is not good enough, the wear is large and the material cannot be shoveled, which will cause no powder or less powder, which needs to be replaced. Only the blade can ensure the normal operation of the equipment.

How to improve the efficiency of Raymond milling

The grinding speed determines the working efficiency of the Raymond mill, especially for some materials that are difficult to crush, how to improve the Raymond mill, this article will give you some tips! To improve the working efficiency of the pulverizer, it is necessary to look at the combination of each machine. The combination of each machine is complete. Then the efficiency will naturally increase. This is a breakthrough point to improve the working efficiency of the mill. There is also the choice of different machine combinations according to different raw materials.
