Raymond Mill
R series Raymond Mill is produced based on many years’ researched and developed, adopted advanced international technology, to meet the clients’ different requirement. It’s the benefits of well-structured, high efficient, low consumption, space-saving, less investment and environment-safe.
Raymond Grinding Mill
For low consumption, low investment, environment-safe , small occupation area, and more efficient compared to traditional mill, it really is traditionally used in metallurgy, building materials, chemical industry and mining to process powder.
The series is utilized in grinding the non-flammable and non-explosive stuff that has the Moh’s hardness below 7, humidity under 6%, including gypsum, talc, calcite, limestone, marble, feldspar, barite, dolomite, granite, kaolin, bentonite, bauxite, iron ore etc., the final products vary from 613 micron to 44 micron. With the function of separator and blower, it can meet different customers’ demand.
Working principle
The powder collector is include cyclone, hopper, conveyor and airlock..The powder is grinded by Raymond mill will moved by ventilation of blower, thronging from analyzer that’s equipped on mainframe being classified to standard powder, then with airflow into separator from tangent direction. The flow of air will generate strong centrifugal force in whirl, one of the most of powder will thrown to machine wall, the powder will fall under hopper and outside of air; Rotary air will up close to central in addition to cone shrink. It’s going to rise when reach to conicity with the bottom of cyclone, forming a stream from as much as bottom in spiral, it is going to be discharged in the top of cyclone separator. After passing muffler and it’ll be inhaled to blower, delivered to the tank ultimately. In this way, a circulatory system mainframe is created. The fabric is grinded continuously, and also the powder will betaken away by airblower, that form a material feeding system. The whole method is closed circulatation. Besides, the feeding system of titanium dioxide powder is under sub pressure states.
There is a screw conveyor under the launch of hopper. A flapper is a component of the release of screw conveyor. They two are utilized to guarantee and block positive-negative pressure of airblow that caused by the running state of whole structure and grinding mill. First of all, the flapper guarantees the positive-negative airblow, so the powder from the hopper, drop in to the entrance of not operational screw conveyor and piled-up. Once the entrance of screw conveyor is piled fully, the inactive screw conveyor will have an important role in locking the airblow. When the flapper doesn’t work, the screw conveyor will probably be reformed being secondary airlock. Furthermore, it discharges powder indirectly and packs products intensively, and avoids the case of less powder or no powder producing resuts of the airlock loose that enhance the rate of productivity of powder.
