Product Specification

325 Mesh Calcium Powder Grinding Production Line Stone Raymond Mill

Product description:
Raymond mill adopts the advanced structure of similar products at home and abroad, and is designed based on the Raymond mill of the same industry. It has high efficiency, low power consumption, small footprint, and small one-time investment. The grinding roller is tightly pressed on the grinding ring under the action of centrifugal force, so when the grinding roller and grinding ring are worn to a certain thickness, it does not affect the output and fineness of the finished product. The replacement cycle of the grinding roller and grinding ring is long, thus eliminating the disadvantage of the short replacement cycle of the wearing parts of the centrifugal crusher. The air selection airflow of the Raymond mill is circulated in the fan-mill shell-cyclone separator-fan, so there is less dust, the operation workshop is clean, and the environment is pollution-free.

Specification:

The Raymond mill is mainly composed of a main machine, an analyzer, a fan, a finished product cyclone separator, a micro powder cyclone separator and an air duct. Among them, the main machine is composed of a frame, an air inlet volute, a scraper, a grinding roller, a grinding ring and a cover.

Working principle of Raymond mill:
When working, the material to be crushed is added into the machine from the feed hopper on the side of the machine cover. Relying on the grinding roller device hanging on the main machine plum blossom frame, it revolves around the vertical axis and rotates itself. Due to the centrifugal force during rotation, the grinding roller swings outward and presses against the grinding ring, so that the scraper scoops up the material and sends it between the grinding roller and the grinding ring. The purpose of crushing the material is achieved due to the rolling and rolling of the grinding roller.

Air selection process of Raymond mill:
After the material is ground, the fan blows air into the main machine housing to blow up the powder, which is sorted by the analyzer placed above the grinding chamber. The material with too coarse fineness falls into the grinding chamber for re-grinding, and the material with fineness that meets the specification enters the cyclone collector with the wind flow. After collection, it is discharged through the powder outlet, which is the finished product. The wind flows back into the fan through the return air duct at the upper end of the large cyclone collector. The wind path is circulated and flows under negative pressure. The increased air volume in the circulating wind path is discharged through the exhaust gas duct between the fan and the main unit and enters the small cyclone collector for purification.

Features:
1. Raymond mill is a vertical structure with small footprint and strong system. It can form an independent production system from raw material rough processing to transportation to powder making and final packaging.
2. Compared with other grinding equipment, the screening rate is as high as 99%.
3. The main transmission device adopts a closed gear box and pulley, which has stable transmission and reliable operation.
4. The important parts of Raymond mill are made of high-quality castings and profiles, with fine craftsmanship, which ensures the durability of the whole set of equipment.
5. The electrical system of Raymond mill adopts centralized control, with advanced and reasonable selection and high degree of automation.

Application:
Raymond mill is widely used in barite, calcite, feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, thermal insulation materials, etc.
