Raymond Mill Working Process

Raymond Mill Working Process

The entire Raymond machine is a vertical structure with a relatively small footprint and a strong system. It can be used as an independent production system from raw material roughing to conveying to milling and final packaging. During the use of the mill, there should be a fixed person 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 Raymond mill and familiar with the operating procedures.

Raymond mill Machine working process

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 Raymond mill main grinding chamber through the vibrating feeder, and the high analysis rate vertical analysis machine is rotated. Under the action of centrifugal force, 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. The fine powder after grinding of the material is brought into the analysis machine for sorting with the circulating wind of the blower. The Raymond mill uses a material with too fine a certain degree of fineness to fall back to the regrind, and the qualified fine powder enters the finished cyclone collector with the airflow. After being discharged through the powder discharge pipe, it is the finished product. In the Raymond grinding room, there is a certain amount of moisture in the material to be ground, heat is generated during grinding, water vapor evaporates, 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.

The important parts of Raymond Mill are made of high-quality castings and profiles. The craftsmanship and rigorous process ensure the durability of the whole set of equipment. Compared with other milling equipment, Raymond machine has a high screening rate and a screening rate of 99%, which is not commonly achieved by other milling equipment. Fineness adjustment, according to the size of the material, soft and hard, water content, specific gravity, the thickness of the processing is also different, the upper analyzer can be adjusted, the rotation speed is high, the fineness is high, the rotation speed is low, and the fineness is low.

After the Raymond mill is used for a period of time, the Raymond mill should be inspected and repaired. At the same time, the wearing parts such as the grinding roller and the blade should be inspected and replaced. The grinding roller device should be carefully checked before and after use to see if there is any Looseness, whether the grease is added.

Construction of Raymond Mill

Want to know the principle and maintenance method of Raymond mill to know the structure of Raymond mill, Raymond mill to host, analysis machine, blower, finished cyclone, pipeline device, motor and so on. The main machine is composed of a frame, an inlet volute, a blade, a grinding roller, a grinding ring, a casing and a motor. Auxiliary equipment includes jaw crusher hoist, electric control cabinet, etc., users can flexibly choose according to the site conditions.
