Product Description

Applications of Raymond Mill:

Raymond mill widely used in grinding the non-flammable and non-explosive stuff which has the Mohs hardness below 7,humidity less than 6%,sucn as gypsum,talc,limestone,marble,barite,dolomite,kaolin,bauxite,iron and so on.it have apply for mine,building materials,chemical industry and other ore materials.

Raymond mill consists mainly of mainframe, analyzer, blower, finished product cyclone separator, micro mist cyclone separator and air duct. The mainframe is composed by frame, spiral into wind, shovel knife, grinding roll, grinding ring, cover shells and motor.

Working Principle of Raymond Mill:

1.The whole machine is collocated with jaw crusher, elevator, hopper, electromagnetic vibrating feeder, main unit, classifier, collector, cloth detester and high-pressure blower.

2. The working principle is as follows: load the stuff for grinding evenly and continuously into the grinding chamber of the main frame.

3.Due to the centrifugal force in rotation, the roller swings go outward and presses closely upon the ring. The shovel carries the stuff to the space between the roller and ring.

4.When the roller rolls, the stuff is thus grinded.

5.After being grinded, the stuff is to be routed to the classifier along wind belt of the blower and the rough powder will be put back to the grinder for regrinding.

6.The fine powder flows into the cyclone collector together with air flow and is expelled from the powder output pipe as product.

7. In the grinding chamber, since the stuff contains moisture to some extent, the heat generated during grinding makes the moisture evaporate; since the pipeline joints are not airtight, the external air is sucked in and the circulation air mass increases.

8.In order to enable the grinder to work in negative pressure, the increased air flow is guided to the duster and sequentially to the atmosphere after purification.


Features of Raymond Mill:

1. Compared with other milling plants, its passing ratio achieves 99%, this is what other mill can not reach;

2. Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.

3.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.

4.The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.

working principle

working principle of raymond grinder mill 

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 circulated under condition of negative and positive pressure.
