Raymond mill

Raymond mill

Raymond Mill is relevant towards the grinding and processing of more than 280 types of non-flammable and non-explosive materials with hardness lower than 7 and humidity lower than 6% in mining, construction ,chemical industry and metallurgy, such as barite, calcite, feldspar,talcum, marble, limestone, clay, glass. The fineness from the finished product could be adjusted from 100 mesh to 325 mesh according to requirements.

Structural Characteristics

The complete raymond grinder is of a standing structure. Raymond mill features small occupying space and strong integration capacity. Raymond mill can take shape a completely independent production system from the lump materials , crushing to finished powder and packaging.

Every one of the finished particles use a good uniformity of fineness, with passing screen rate as high as 98%. This is what other machine cannot reach.

The machine adopts electromagnetic vibrating feeder, which ensures even and regular feeding.Raymond mill is easy to adjust, small in dimension, light in weight, with lower oil and power consumption and easy to maintain.

The transmission device of the main unit is equipped with an in depth gearbox which ensures its smooth transmission and reliable operation. Attendance of operater is not required within the mill operating room because the adoption of advanced central control console switch.

Working Principle

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

The significant principle can be as follows: load the stuff for grinding evenly and continuously in to the grinding chamber with 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 for the classifier along wind belt from the blower and also the rough powder will probably be put to the grinder for regrinding. The fine powder flows into the cyclone collector along with air-flow and is expelled from your powder output pipe as product.

Inside the grinding chamber, considering that the stuff contains moisture somewhat, heat generated during grinding helps make the moisture evaporate; because the pipeline joints are not airtight, the external air is sucked in and also the circulation air mass increases. To be able to encourage the grinder to operate in negative pressure, the increased air flow is guided for the deuster and sequentially for the atmosphere after purification.
