Raymond Mill:

The Grinding Production Line contains vibrating feeder, jaw crusher, grinding mills, milling machinery, industrial pulverizers etc. Stone production line includes vibrating feeder, jaw crusher, impact crusher, vibrating screen, belt conveyor and centrally electric controlling system, etc. The designed capacity is from 50t/h to 500t/h. To meet customers specific requirement, we can also add other equipments such as cone crusher, dust catcher on the production line.

Working Principle

Large materials are crushed by Jaw crusher to the needed sizes firstly, then the materials are elevated to storage hopper by bucket elevator, thirdly, the materials are fed into the grinding chamber for grinding by vibrating feeder equably and continuously. The powder after grinding goes upwards together with the airflow, after separated by powder separator, those which can meet the fineness requirement enters into the cyclone powder collector through pipe together with the airflow, and then discharged from the discharge valve as final products. The airflow is sucked into centrifugal blower through wind recycling pipe at the upper part of cyclone powder collector. The mainframe is driven by the speed reducer through the central axis in the mill. The quincunx stand connected with the upper part of central axis, at the quincunx stand, rollers are set and by which the vibrating pivot formed. Below the quincunx stand and rollers there is shovel system. Materials are fed into the space between rollers and shovels when they are turning, and then be grinded by the pressure produced when rollers are turning, thus powder is made.

Technical Advantage:

1 The ladder-shaped rollers and rings improve crushing efficiency greatly. The rollers and ring are designed in the main machine of an inverted trapezium, which control the materials slip velocity between rollers and rings. They can extend the grinding time, and enhance the crushing effect.
2 The press springs with balancing and pressurized function and the forming resilient connection with steady and vibration reducing function are invented into our machines.
3 The powder classifier adopts high density impeller, which can increase precision of powder and capacity.
4 There is high-efficiency and energy-saving blower installed on our machine. The efficiency of prismatic blade equipped on the traditional machine is only 62%, but the efficiency of the energy saving blower, whose impeller and blade are both stamping, is 85%.
5 There is convenient impeller adjusting device. The clearance between housing and ending of powder classifiers blade also effects fineness. Our mill is convenient to adjust the fineness.
