Raymond

Raymond mill is a grinding equipment made with advanced technology, suitable for grinding a variety of materials, such as non-metallic mineral materials such as limestone, calcite, marble, talc, gypsum, and a small amount of metallic mineral materials. LANE’s machine design is scientific and reasonable, compact, cost-effective, reliable performance, and can achieve a high-efficiency, low-energy production process.

Composition Structure

Main machine part: including frame, air inlet volute, scraper, grinding roller, grinding ring and cover. These components together constitute the core working area of ​​​​the Raymond mill, responsible for the grinding process of materials.

Auxiliary equipment: such as jaw crusher, bucket elevator, electromagnetic vibrating feeder and electric control cabinet, etc., these equipment assist in the crushing, transportation and precise control of materials to ensure the smooth progress of the entire grinding process.

Working Principle

After being crushed into shivers less than 20mm, the materials are carried into store bucket by bucket-lifter then pull into the main frame by electro-vibrating feeder at fixed quantity for grinding.

The five grinding roller devices that are hung on star rack in the main frame rotate around the center axis and the grinding roller makes the rotation around grinding roller and around the axis at the same time. with the effect of the centrifugal force, grinding roller sways outward and impacts grinding ring to place the grinding materials on shovel between them and achieve the crushing and grinding effects by the rolling and crushing of grinding roller, The crushed powder is blown into the analytic engine on the upper of main frame by the air current of air blower for divisional screening.

The thicker than fine standard will fall into the main frame for regrinding and the qualified far fine standard will enter the large cyclone collector by the wind currents and then was discharged through the discharge pipe and becomes the finished product.

The purified air current blows into air blower through the pipe on the upper of large cyclone collector. The wind is circular and the air current in the blows under pipeline negative pressure except that the air current from air blow to pulverizing room is under positive pressure. so the health conditions are good in the workshop.

Advantages

This Raymond mill consists of main frame, air blower, bucket elevator, electro-vibrating feeder, store bucket, jaw crusher, pipe system, cyclone collector, electric control cabinet, etc.

Smooth operation, small occupation area:Raymond mill host transmission device adopts sealed gearbox and a belt wheel to get a smooth transmission; the vertical structure can save the space and operate conveniently.

Large capacity, high rate:To save the production cost by screening a molding material grinding; compared with other milling equipment, it enjoys higher screening rate, the 2-screening rate is as high as 99%.

Simple operation, wide application range:The electrical system of Raymond Mill adopts centralized control. the size of finished product can be adjusted between 80 – 325 mesh range.

Structure optimization, low maintenance cost:The important parts are made of high-quality casting and molding manufacturer, meanwhile, it also with features of high durability, convenient replacement of wearing parts.
