Application :
The Raymond Mill is high efficiency recycling powder making equipments of closed circuit used in the field of middle and small scale mine, chemical industry, building materials, metallurgy, refractory materials, pharmacy, cement, etc. The output and energy consumption of the products have met the national standards and ranked advanced level in the country. And it has received good reputation from all trades and professions.Raymond mill is designated for processing superfine powder of over 300 noninflammable and nonexplosive materials with Mohs hardness below Grade 8 and water content below 6% in the field of mine ,chemical industry, building materials, such as barite, calcite, potash feldspar, steatite, marble, limestone, dolomite, fluorite, lime, active carclazyte, active carbon, bentonite, kaolin, cement, phosphorus ore, gypsum, glass, manganese ore, titanium ore, copper mine, chrome ore, refractory materials, heat preservation materials, coal coke, coal fines, black, , bone meal, titanium white powder, ,quartz, and so on. The finished products can be adjusted freely from 100 to 325 meshes for some materials.

Raymond Mill is made up of the Mainframe, Separator, Pipeline System, Air Blower, Jaw Crusher, Hopper Elevator, Electromagnetic Vibrating Feeder, and Electric Control Motor and so on .

Raymond Mill Structural Characteristics :
The whole raymond grinder is of a standing structure. Raymond Roller mill features small occupying space and strong integration capacity. Raymond Roller mill can form an independent production system from the lump materials , crushing to finished powder and packaging. All the finished particles have a good uniformity of fineness, with passing screen rate as high as 98%. This is what other machine cannot reach. The machine adopts electromagnetic vibrating feeder, which ensures even and regular feeding.Raymond mill is easy to adjust, small in dimension, light in weight, with lower oil and power consumption and easy to maintain. The transmission device of the main unit is equipped with a close gearbox which ensures its smooth transmission and reliable operation. Attendance of operater is not necessary in the mill operating room because the adoption of advanced central control console switch.

Raymond Mill features:
★ Three-dimensional structure
★ land-saving
★ The screen-passing rate can reach to 99%
★ The transmission is steady and reliable;
★ The transmission device of mainframe adopts airtight gear case and zonal wheel.
★ Centralized control for the electric system, convenient to operate.

Working Principle:
Load the stuff for grinding evenly and continuously into the grinding chamber of the main frame. Due to the centrifugal force in rotation, the roller swings outward and presses closely upon the ring. The shovel carries the stuff to the space between the roller and ring. When the roller rolls, the stuff is thus grinded.After being grinded, the stuff is to be routed to the sorter along the wind belt of the blower and the rough powder will be put back to the grinder for regrinding. The fine powder flows into the product cyclone collector together with airflow and is expelled from the powder output pipe as product.In the grinding chamber, since the stuff may contain moisture to some extent, the heat generated during grinding makes the moisture evaporated; since the pipeline joints are not airtight, the external air is sucked in and the circulation air mass increases. In order to enable the grinder to work under negative pressures, the increased airflow is guided to the deduster anew sequentially to the atmosphere after purification.
