Raymond Mill

is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6%. Raymond Mill is mainly used in mining, construction, chemical industry and metallurgy. The materials which can be grinded by our Raymond mill is barite, calcite, feldspar, talcum, marble, limestone, clay, glass, etc. The fineness of finished product can be adjusted from 100 mesh to 325 mesh according to requirements.

The whole plant of

Raymond Mill

is a vertical structure of strong systematic characteristic. So Raymond grinding mill occupies small area. From crushing of raw material to grinding and packing is an independent production system.

Compared with other grinding mills, its passing ratio achieves 99%, which is what other grinding mills cannot reach;

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

Main parts of the whole

Raymond mill

plant are made from cast and steel of high quality. The technics is so subtly that insures the durability of whole plant; The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.

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

The Raymond mill working principle is as follows:

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 deduster and sequentially to the atmosphere after purification. Second warehouse for regrinding with the steel ball and scaleboard. In the end, the powder is discharged by output material board and the end products are completed.

• The

  Raymond mill

  is of a standing structure which makes small occupying space and strong integration capacity.
• The whole Raymond mill plant can form an independent production system from the lump materials, crushing to finished powder and packaging.
• All the finished particles have a good uniformity of fineness, with passing screen rate as high as 98%. This is what other grinding machine cannot reach.
• The raymond mill is easy to adjust, small in dimension, light in weight, with lower oil and power consumption and easy to maintain.
• Smooth transmission and reliable operation.
• Attendance of operator is not necessary in the Raymond mill operating room.
