Product Description

YGM series Raymond roller mill is also called Raymond grinding mill, Raymond pulverizer. YGM series Raymond roller mill is the new type Raymond mill of our company, which is suitable for processing various non-flammable and non-explosive mineral materials with Moh's hardness less than 9.3 and humidity less than 6%.

The main parts of Raymond roller mill is grinding roller, grinding ring, grinding roller assembly, the plum flower frame, air
flue, coupling, perching knife and so on.

Technology Date of Raymond Mill

Note: This specification is just referencing, any changes are subject to the products.

Raymond roller mill can be widely used in the fields of metallurgy, construction, chemical industry, mining, highway construction etc,. The granularity of the finished powder size can be adjusted between 30 and 425 mesh. Examples of processing materials include quartz, feldspar, barite, calcite carbonate, limestone, talc, ceramic, iron ore, carborundum, bauxite, rock phosphate, coal and other materials, about 400 kinds of materials in total.

Working Principle of Raymond Mill

The 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 grind. After being grind, 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.

Advantages of Raymond Mill

1. Higher output. Its output increases by 10%-20% comparing with Raymond mill under the same power condition.

2. Larger range of final fineness. Size of final product can be 0.613 mm (30 mesh) –0.033 mm (425 mesh). Some can reach the fineness of 0.013 mm (1000 mesh).

3.Good dust control. High Pressure Suspension Mill meets the requirement of national dust-dump standard.

4.Easy to operate. The whole system is combined by some independent systems, and the cohesion between the systems is good.

5. Excellent sealing. The multi-class seals are adopted to keep the grinding equipment tight closed.
