Raymond Grinding Mill Introduction:
Raymond Grinding Mill is mainly used in power generation and processing 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 metallurg.

Raymond Grinding Mill Application:
Raymond Grinding Mill is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar, talcum, marble, limestone, clay, glass. The fineness of the finished product can be adjusted from 100 mesh to 325 mesh according to requirements

Raymond Grinding Mill Structural Characteristics:
1.Raymond mill features small occupying space and strong integration capacity.
2.Easy to adjust, small in dimension, light in weight
3.With lower oil and power consumption and easy to maintain.
4.Smooth transmission and reliable operation.

Raymond Mill Working Principle:
load the stuff for grinding evenly and continuously into the grinding chamber of the main frame. 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. When the roller rolls, the stuff is thus grinded. 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. The fine powder flows into the cyclone collector together with air flow and is expelled from the powder output pipe as product. 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. 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.
