Raymond Mill Works

When the Raymond mill is working, the material to be crushed is fed into the machine from the feeding hopper on the side of the hood, and the grinding roller device suspended on the main stand of the main machine is revolved around the vertical axis while rotating itself, due to the rotation. When the centrifugal force acts, the grinding roller swings outward and presses against the grinding ring, so that the blade shovel the material to the grinding roller and the grinding ring, and the purpose of pulverizing the material is achieved by rolling rolling of the grinding roller.

Raymond mill wind selection process

After the material is ground, the fan blows the wind into the main casing, blows up the powder, and sorts it through the analyzer placed above the grinding chamber. The material with too fineness falls into the grinding chamber and re-grinds, and the fineness meets the specifications. Enter the cyclone collector with the wind flow, collect it and discharge it through the powder outlet, which is the finished product. The wind flow is returned to the fan by the return air pipe at the upper end of the large cyclone collector. The air path is circulated and flows under the negative pressure state. The increased air volume of the circulating air path is partially discharged through the exhaust pipe between the fan and the main engine, and enters the small cyclone collection. The device is cleaned.

Raymond mill working process

The whole structure of Raymond Mill is composed of main machine, analysis machine, pipeline device and blower. It can be equipped with crusher, hoist, electromagnetic vibrating feeder and electronically controlled motor according to user needs. After the material is pulverized to the required particle size, the material is sent to the storage hopper by the hoist, and then the material is uniformly and continuously fed into the main machine grinding chamber through the vibrating feeder, and the grinding roller swings outward due to the centrifugal force during rotation. In 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.

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 tube. It is the finished product. In the grinding chamber, 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 that the mill works under negative pressure. 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 maintenance and maintenance

  1. 1. During the use of Raymond 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. 2, in order to make the Raymond 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. 3. After using the Raymond 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 it is checked. There is looseness, and the grease is added.
  4. 4. When the 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.
