Raymond Mill

Application of Raymond mill / Raymond grinder:

The Raymond grinder (Raymond mill) is rather versatile and widely used for grinding the barite, calcite, feldspar, glass, marble, limestone, kaolin, porcelain clay, and slag, etc, below scale 9.3 of Mohs hardness and 280-odd sorts of non-inflammable and non-explosive stuff in the trades of mining, metallurgical industrial, chemical engineering and building material for high fine powder generation and processing. The product size is adjustable in the range of 80-325 meshes. It is possible to product 30-80 mesh coarse powder through special device in the machine.
In addition, In the chamber of Raymond mill, since the stuff of Raymond grinder (Raymond mill) may contain moisture to some extent, the heat generated during makes the moisture evaporated.

The features & benefits of Raymond Mill:

Working principle of Raymond mill:

Raymond mill is mainly composed of main unit, analyzer, blower,powder collector,dust catcher,hopper,bucket elevator,jaw crusher. Among them, the main unit consists of frame, blow shell, shovel, grinding roller and grinding ring,reducer.
1.The lump material will be conveyed into the storage hopper by the bucket elevator after it is crushed into the required particle size by the jaw crusher.
2.Then electro vibrating feeder will uniformly transfer the material into the grinding chamber of the host machine.
3.The material is up thrown and fed into the space between the grinding roller and grinding ring in the process of synchronous rotation of the shovel and the grinding roller, and forms a cushion material layer.
4.The material on this layer is grinded between the grinding roller and the grinding ring. Thus, the purpose of powder production is achieved.
5.The grinded powder will be carried by the airflow of the blower into the analyzer for classification.
6.The powder with the qualified fineness will enter the large powder cyclone collector, together with the airflow through the pipes, for classification, and then, will be discharged by the discharging device, as the finished product.
7.The airflow is sucked into the air blower through the air return pipe on the upper part of the large cyclone collector.
8.The unqualified powder will be thrown to the external wall by the airflow and separated from the airflow.
9.The coarse powder will fall into the grinding chamber for regrinding due to its own gravity.
10.The whole airflow system is closed and cyclic, and it flows under the positive and negative pressure circularly.
