Raymond Mill

We are offering raymond mill etc. Introduction
raymond mill is used to grind barite, calcite, potash feldspar, talcum, marble, limestone, ceram and slag below scale 7 of moth's hardness and 280 odd sorts of non-inflammable and non-explosive stuff in the traded of mining, building material, chemical engineering and metallurgy for power generation and processing.
features
vertical structure makes the machine occupying small area.
the product size is adjustable on required in the range of 100-425 meshes.
Compared with other grinding mill, its passing ratio achieves 99%, this is what other mill can not reach.
Application
adopting closed circulation, raymond mill is a new type and efficient grinding equipment which can replace ball mill. It is widely used in many industrial sectors from medium or large scale mines, chemical plant, building materials, metallurgy, refractory materials, and so on.
Working principle
raw materials are crushed by jaw crusher to the size required, and then the crushed materials enter 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 circulated under condition of negative and positive pressure.
