Raymond roller mill is a relatively popular milling equipment in the milling industry. It was introduced to China in the 1980s and has developed steadily in the domestic market. It has gradually formed many branches and is grinding in many materials. It plays a huge role. The roller mill device is an important component of the Raymond mill and plays an irreplaceable role in the normal operation of the raymond mill. Mainly in the process of the main machine of Raymond mill, when Raymond grinds the material, the material is crushed by the centrifugal force of the roller device. Since the roller device is so important, how to maintain it and how to replace it for a long time is a problem that cannot be ignored.
First, keep the load on the raymond roller mill so that the flow rate is uniform. Check the flow distribution of the whole raymond roller mill and the uniformity of grinding, maintain the adjustment ability of the Raymond mill, and clean the raymond roller mill with a scraper or brush; secondly, check the working condition of the raymond roller mill device regularly, paying special attention to the cross-arm shaft and the short-head diameter. When the fastening bolts are tightened, the accident caused by the loose screws and the falling off of the raymond roller mill can be prevented. Next, the temperature of the surface of the raymond roller mill and the temperature of the bearing and the motor should be regularly checked. The increase of the rotational temperature of the transmission system can cause the belt to heat up. Finally, the Raymond mill should be inspected after a period of use (about 500 hours), and the wearing parts such as the raymond roller mill and the blade should be inspected and replaced. The raymond roller mill device should be carefully inspected before and after use. To see if there is looseness, whether the grease is sufficient.
Raymond mill's complete equipment mainly includes transmission, jaw crusher, hoist, feeding device, pipeline device, blower, analysis machine, main engine, dust removal device and so on. When installing these devices, firstly, the base of the transmission should be dropped into the pit to fill in the flat. At this time, it is necessary to control the height. Secondly, the installation of the main unit should be in contact with the cement foundation and the ground at the lower end of the base before installing the main unit. Rubber anti-vibration pad on the screw joint of the foot to reduce the vibration of the main machine; nextly, the installation of the pipeline device, the pipeline device should be installed in strict accordance with the effect diagram during installation, do not arbitrarily change and increase, and ensure the sealing at each pipe connection Finally, when the whole set of equipment is installed, it is debugged. The most important thing in the debugging process is the control of fineness of the finished product, and the fineness of the finished product is mainly controlled by the analysis machine and the fan, so the analysis machine and the fan The speed must be controlled well. Keep in mind that the speed of the fan should not be too large and moderate. Under normal circumstances, the fan equipped by the manufacturer can successfully complete the task, and there is a certain surplus adjustment space to ensure some special circumstances.
