Raymond mill is widely used in the field of metallurgy, building materials, chemical industry and mining to process powder. This Raymond mill is used to grind non-flammable and non-explosive material which has Moh’s hardness below 9 and humidity less than 6%, such as gypsum, talc, calcite, limestone, marble, feldspar, barite, dolomite, granite, Top Quality Raymond Mill, limestone raymond mill for sale, kaolin, bentonite, bauxite, iron ore, etc. the final product with size from 30 to 425 mesh can meet different customers’ various requests.
Structure of Top Quality Raymond mill :
The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to grinding and packing is an independent production system.
Compared with other vertical roller mill plants, its passing ratio achieves 99%, this is what other mill can not reach;
Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably,
Main parts of the whole plant are made from cast and steel of high quality. The technics is so subtly that insures the durability of whole plant,
The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.
Working principle of Top quality raymond mill :
The raw material enters grinding chamber, shoveled up by the shovels and ground between the rollers and ring. After this, the ground material is carried by the air from the blower into the separator for screening, and the qualified fine powder becomes final product and comes into the cyclone powder collector, Ring Medium-speed Micro-powder Grinding Mill Price the other unqualified powder falls down to be re-ground. The circular air returns back to the blower, so the above process will be repeated, and the remaining air enters the bag filter in order to protect the circumstance.
Firstly, raw material is crushed by jaw crusher to the size required, then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder, evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind.
After this, the ground stuff are carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The set’s airflow system is closely sealed up and
Large materials are crushed by Jaw crusher to the needed sizes firstly, then the materials are elevated to storage hopper by bucket elevator, third, 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, Professional High Pressure Hanging Roller Mill price after separating 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.
