Raymond Mill Works

Raymond Mill Works

Raymond mill is composed of main engine, analysis machine, pipeline device and blower. It can be equipped with crusher, hoist, electromagnetic vibrating feeder and electronically controlled motor according to user needs.

How the Raymond mill works:

After the Raymond mill crushes the material to the required particle size by the jaw crusher, the material is sent to the silo by the hoist, and then the vibrating feeder feeds the material evenly and continuously into the main mill of the Raymond mill. Due to the centrifugal force during rotation, the grinding roller swings outward and presses against the grinding ring. The blade shovels the material and sends it between the grinding roller and the grinding ring, which is crushed by the rolling of the grinding roller. Fineness can be adjusted.

The fine powder after grinding of the material is brought into the analysis machine for sorting with the circulating wind of the blower, and the finely coarse material falls back to the regrind, and the qualified fine powder enters the finished cyclone powder collector with the airflow, and is discharged through the powder discharging pipe. That is the finished product. In the mill grinding room, there is a certain amount of moisture in the material to be ground, heat is generated during grinding, water vapor is evaporated, and the pipelines of the whole machine are not tightly connected. The outside air is sucked in, so that the circulating air pressure is increased to ensure the mill is under negative pressure. Working in the state, the increased air flow is discharged into the dust remover through the residual air duct, and is purified and discharged into the atmosphere.

Raymond mill machine structure features:

1. Three-dimensional structure, small footprint, strong set, from the block to the finished powder alone into a production system. 2. The fineness of the finished powder is uniform, and the screening rate is 99%, which is difficult for other milling equipment. 3, the machine transmission device uses a closed gear box and pulley, the transmission is stable and reliable. 4. All the important parts are made of high-quality steel, and the wear parts are made of high-performance wear-resistant materials. The whole machine has high wear resistance and reliable operation. 5. The electrical system adopts centralized control, and the grinding workshop can basically realize unmanned operation and maintenance.

Maintenance and maintenance of Raymond mill: 1. During the use of the mill, there should be fixed personnel responsible for the care, the operator must have a certain level of technology. Before the installation of the mill, the operator must carry out the necessary technical training to understand the principle performance of the mill and familiar with the operating procedures. 2, in order to make the mill normal, the equipment "equipment maintenance and safety operation system" should be established to ensure the long-term safe operation of the mill, as well as necessary maintenance tools and grease and corresponding accessories. 3. After using the mill 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. When the Raymond grinding roller device is used for more than 500 hours to replace the grinding roller, the rolling bearings in the roller sleeve must be cleaned, and the damaged parts should be replaced in time. The fueling tool can be manually pumped and greased.
