About the performance characteristics of Raymond Mill

Raymond mill, also known as Raymond mill and raymond mill, is a kind of milling mill that replaces the ore powder by ball mill. The roller of Raymond mill is pressed tightly on the grinding ring by the centrifugal force. Therefore, when the grinding roller and the grinding ring are worn to a certain thickness, the yield and fineness of the finished product are not affected. The grinding roller and grinding ring of the Raymond mill have a long replacement cycle, thus eliminating the shortcomings of the replacement cycle of the wearing parts of the centrifugal pulverizer.

Raymond mill is suitable for non-flammable and explosive mining and chemical industry, such as barite, calcite, potassium feldspar, talc, marble, limestone, ceramics and glass, with Mohs hardness not greater than 7 and humidity below 6%. In the building materials, metallurgy and other industries, more than 300 kinds of materials are processed, and the finished product size is adjusted in the range of 80-425 mesh. Structure and composition:

Raymond mill is mainly composed of main machine, analysis machine, blower, finished cyclone, pipeline device, motor, etc., where the main machine is made up of frame, inlet volute, blade, grinding roller, grinding ring, casing and motor. The auxiliary equipment includes jaw crusher, bucket elevator, electromagnetic vibrating feeder, electric control cabinet, etc. The user can flexibly choose according to the site conditions.

work process of raymond mill:

The whole structure of Raymond Mill is composed of main engine, analysis machine, pipeline device, blower, and jaw crusher, bucket elevator, electromagnetic feeder and electronic control motor which can be equipped 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 grinding chamber of the Raymond mill by the vibrating feeder. The centrifugal roller acts outward due to the centrifugal force during the rotation. Swinging, pressing 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, 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.

Performance characteristics:

  • 1. The whole machine is a vertical structure with small floor space and strong system. From rough processing of raw materials to conveying to milling and final packaging, it can be an independent production system.
  • 2. Compared with other old-fashioned milling equipment, the screening rate can be as high as 99%.
  • 3. The main drive unit adopts a closed gear box and pulley, which makes the transmission smooth and reliable.
  • 4. The important parts are made of excellent castings and profiles, and the craftsmanship is fine, which ensures the durability of the whole set of equipment.
  • 5. The electrical system adopts centralized control, and the selection is advanced and reasonable.
