Main Application of Raymond Mill(Raymond Grinder)

Raymond Grinder(Raymond Mill) is used to grind barite, calcite, potash feldspar, talcum, marble, limestone, ceram and slag 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 metallurgy for power generation and processing. The product size is adjustable on required in the range of 100-325 meshes.

Functional Process of Raymond Grinder(Raymond Mill)

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 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 sorter along the wind belt of the blower and the rough powder will be put back to the grinder for regrinding. The fine powder flows into the product cyclone collector together with airflow and is expelled from the powder output pipe as product.

In the grinding chamber, since the stuff may contain moisture to some extent, the heat generated during grinding makes the moisture evaporated; 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 under negative pressures, the increased airflow is guided to the deduster anew sequentially to the atmosphere after purification.

The MTM Raymond Mill is a leading-world-level industrial mill. The Mill is designed by our own engineers and technical workers, basing on industrial mill research of many years and adopting world-leading-powder processing technology. Our machine adopts many advantages from numbers of mill all over the world, such as trapeziums working surface, flexible connection, roll linked pressure boost, etc. It has overcome the traditional mills defect completely in application, capacity, fineness, energy consumption, service life, etc. And it is the ideal substitute of the traditional mill, such as Raymond mill, high pressure suspension mill, ball mill, etc. Nowadays, our products have been widely used in metallurgy industry, electric power industrial, chemical, building, steel industry, coal industry, etc. And it has brought large economic benefits to our customers and the society.

Technical Advantage Of The MTM Raymond Mill:

The ladder-shaped rollers and rings improve crushing efficiency greatly. The rollers and ring are designed in the main machine of an inverted trapezium, which control the material’s slip velocity between rollers and rings. They can extend the grinding time, and enhance the crushing effect. The press springs with balancing and pressurized function and the forming resilient connection with steady and vibration reducing function are invented into our machines. The powder classifier adopts high density impeller, which can increase precision of powder and capacity. There is high-efficiency and energy-saving blower installed on our machine. The efficiency of prismatic blade equipped on the traditional machine is only 62%, but the efficiency of the energy saving blower, whose impeller and blade are both stamping, is 85%. There is convenient impeller adjusting device. The clearance between housing and ending of powder classifier’s blade also effects fineness. Our mill is convenient to adjust the fineness.

Working Principle Of The MTM Raymond Mill:

Air is driven into the undersurface of the grinding ring and flows upward, carrying fines to the classifying section. The classifier allowed the pulverized material to pass and the oversized particles are drove back to the grinding chamber for further processing. The whole mill operates under negative pressure conditions, which can maximize the service life of major mechanical components. Thus minimizing mill maintenance and plant housekeeping problems have been solved.
