Raymond Mill Use And Maintenance Methods

Raymond Mill Use And Maintenance Methods

Raymond mill is a common type of mill. It is suitable for high-fine powder processing of more than 280 kinds of materials with Mohs hardness not more than 9.3 and humidity below 6%. The finished product size is in the range of 80-325 mesh. Adjust between. The equipment is reliable in operation, high in screening rate and long in service life of consumable parts. It is essential to maintain the good performance of the machine. Correct operation and maintenance are essential. It is also the basis for your benefit and loss reduction. How to use and maintain the mill?

First, the correct switch machine steps

1. Preparation before starting the machine

Before starting the equipment, check whether all the inspection doors are closed tightly, check whether the feeding port of the equipment meets the feed size and adjust the speed of the analyzer to reach the approximate product size. In addition, it is necessary to pay attention to the equipment to be started at no load, and the equipment can be fed after the equipment is stable.

2, boot step

Booting steps: bucket elevator, crusher, analyzer, blower, Raymond mill mainframe, the electromagnetic vibrating feeder should be started immediately after starting the main machine. At this time, Raymond grinding work is the beginning.

3, shutdown steps

Shutdown procedure: first close the feeder and stop feeding for about one minute, then stop the main machine, blow off the residual powder, stop the blower, and shut down the analyzer.

Second, the precautions in the use process

  1. 1. The mill manufacturer will guide the installation of the equipment on site, and will provide technical training for the operators. During the use, professional fixed personnel should be responsible for the care.
  2. 2. If abnormal noise occurs in any part of the machine, or if the load suddenly increases, stop the machine immediately and check the fault to avoid major accidents.
  3. 3, Raymond mill according to the nature of the material, the degree of processing thickness is also different, you can adjust the upper analyzer to control the fineness.
  4. 4. The air volume control valve located on the air intake pipe of the fan is generally opened to a larger position and adjusted according to the fineness and output requirements. The regulating valve located on the exhaust pipe of the exhaust port can be adjusted to the inlet without dust emission, but the air volume should not be too small, otherwise the air duct under the main unit will easily precipitate materials.

Third, Raymond mill maintenance methods

During the work process, the wear of the wear parts of the equipment should be checked regularly. The Raymond mill accessories should also be available on site to avoid delays in equipment operation when replacement is required. Good maintenance and timely maintenance can greatly improve the performance of the equipment and extend the service life of the equipment, thus creating more economic value for you.

The upper end of the main shaft of Raymond mill uses sliding bearings or copper sleeves, and the other transmission parts adopt rolling bearings. Therefore, it must be operated under good lubrication conditions, otherwise the bearings will be damaged and the service life will be shortened. The maintenance methods are as follows:

  1. 1. The spindle refueling time is twice per shift. If the oil in the oil cup is not lost or the loss is too slow, the oil passage should be cleaned immediately.
  2. 2, evenly feeding, too much feeding will block the air duct, reduce production, easy to burn the motor, too little feed will also reduce production. It is forbidden to add large materials and metal blocks to the machine. If it is found to be stopped immediately, it will damage the grinding roller and the grinding ring or deform the plum blossom frame.
  3. 3. After the mill is used for a period of time, it should be repaired and repaired. At the same time, the wearing parts such as the grinding roller and the blade should be repaired and replaced. The grinding roller device should be carefully checked before and after use to see if there is looseness. Whether the lubricating grease is sufficient.
  4. 4. When the remaining wall thickness of the grinding roller ring is less than 10mm, the scrapping standard has been reached and should be replaced immediately.

Proper use and maintenance methods will enable the machine to perform better, ensure production efficiency and finished powder quality, thus ensuring your profit.
