raymond mill brief description

Usage and Application

The Raymond Mill is used to grind materials in the fields of building materials, mining, metallurgy and chemical industry, and the materials must be non-flammable and non-explosive materials, such as limestone, calcite, barite, dolomite, potassium feldspar, marble, talcum, gypsum, kaoline, medical stone, rock phosphate, manganese ore, glass, ceramic, active carbon, carbon black, fireproof materials, heat preservation materials, chemical materials and so on(300 kinds of materials), the materials should have the hardness less than 7 in Moh's scale and the humidity less than 6 percent. The granularity of the end products can be adjusted from 30 to 325 meshes.

raymond mill Woking Principle

After the materials enter the grinding chamber of the main machine, the grinding roller swings outward and presses closely upon the grinding ring due to the centrifugal force generated by the rotation of the main shaft. The blade carries materials to the space between the grinding roller and grinding ring, and the materials are ground as the grinding roller rolls.

After being grinded, the powder will selected by classifier via the cycle wind of the blower, and the rough powder will be bake to the grinding chamber for regrinding, the qualified powder will brought into the powder collector together with airflow, and the powder comes out as the end product while the airflow goes back to the powder collector in cycling to make the machine work normally, the remained airflow comes out after purification by dust filter.

raymond mill Features

1. The whole mill is of spatial structure , less premise and systemic strong. The whole system from roughing, transportation, powder collecting to packaging forms a independent production system.
2. Even granularity, sieving rate 99%, which is unapproachable for other mills.
3. The driving device applies inclosed gear box and belt pulley, so the transmission is calm and the operation is reliable.
4. All the main parts of Raymond Mill adopt high quality steel, the resistant parts use high-performance proof materials, so the whole system has high wear resistance and reliable performance. The blade frame of the main machine keeps in touch with the materials , it is consisted of the upper part and lower part, when the lower part is worn down , just take down the bolts to exchange it .
5. Centralized controlling of the electrical system, unmanned operation , easy maintenance.
6. Less dust pollution, low noise.
7. Adopting electro-vibrating feeder , it can feed evenly and is easy to adjust, features miniature size, light in weight, power saving and easy maintenance.
