After the supplies enter the grinding chamber on the main frame, the grinding roller swings outward and presses closely upon the grinding ring as a result of the centrifugal force generated by the rotation in the key shaft. The blade carries materials for the space between the grinding roller and grinding ring, and materials are ground as the grinding roller rolls.

Soon after being ground, the powder is selected by classifier through the cycle wind from the blower along with the rough powder are going to be back to the grinding chamber for regrinding. The qualified powder is brought into the powder collector with each other with airflow. The powder comes out as finish items while the airflow goes back to the powder collector in cycling to make the machine function normally. The remained airflow comes out immediately after purification by dust filter.

With the extensive development of non-metallic minerals in the field of ultra-fine powder application, downstream enterprises are increasingly demanding non-metallic mineral products. Especially for product fineness has higher requirements. This makes the traditional Raymond mill appear to be inadequate.

Technology innovation is a necessary condition for the development of Raymond mill. Our research on Raymond grinding equipment also has a very long history. As new generation of Raymond mill, MTM series medium speed trapezium mill and MTW series trapezium mill are welcomed by custom.

The new Raymond mill is vertical structure, small occupation area, and strong systemic. From the rough processing of raw materials to the delivery to the milling and the final packaging, it can become an independent production system. Compared with other grinding equipment, the through sieving rate is as high as 99%. An important component of Raymond mill adopts high-quality castings and extrusions manufacturing, fine craft, rigorous process, to ensure the durability of the whole set of equipment.

The technology of micro coal atomization, its result of independent research and development, can boost the transformation and upgrading of coal industry effectively. The so-called micro coal refers to the coal powder meeting the standard of fineness after coal is ground by Raymond mills.

The dry-process production is a kind of new technology. Currently, when building the ceramic board production line, some customer would import the Raymond mill at the time of purchasing pelletizer. However, actually, the domestic grinding equipment can absolutely meet the same demands. And compared to the foreign equipment, it is much cheaper and can increase alternatives for investment on future ceramic industry.

The customer is a leading developer and manufacturer of high-quality calcium carbonate powder in Vietnam, and has established an advanced modern grinding line system that meets European standards. The system consists of 12 machines operating on coated and uncoated lines. The products produced are of high and stable quality, and meet the quality management standard ISO 9001:2015.

From 1906 to today, Raymond mill development than a century, was originally used as a coal grinding equipment Raymond mill , continuous development and innovation , has been widely used in various industries. we look over a hundred years Raymond mill history of the development , which has been constantly adapt to a variety of needs, but also because the process is simple, reasonable structure, easy maintenance , which is widely favored by the milling industry , Raymond mill in milling industry is essential.

The whole structure of Raymond mill is composed of a host machine, analysis, plumbing, air blower, finished cyclone separator, jaw crusher, bucket elevator, electromagnetic vibration feeder, electric motors and other components. The host is composed of a frame, Raymond mill inlet volute, blade, grinding, grinding ring, a cover casing and a motor.

The whole working process of Raymond Mill (the process of grinding material): the bulk materials by jaw crusher to desired size, by the elevator will be material to the hopper, the vibrating feeder evenly and quantitatively and continuously into the indoor host grinding grinding, grinding after the powder is fan airflow. Through the analysis of machine grading, fineness of powder will meet with the gas flow through the pipe into the large cyclone collector, were isolated and collected, then powder tube is finished powder. The airflow from large cyclone collector inhalation top return air duct blower. The air current of the whole system is a closed loop, and circulation in the flow of positive and negative pressure condition.

In the grinding chamber internal grinding material with certain water content, the grinding heat generated in grinding chamber gas evaporation changes the gas flow rate, and the pipeline connection is not tight outside the gas is inhaled, the circulating air volume increase, is this by adjusting the fan with the host legacy of pipe to flow balance, and the gas into the small cyclone collector excess, the fine powder gas into the collection down, then the cyclone collector upper exhaust pipe into the atmosphere, or into the dust collector with the exhaust gas purification.

The 65Mn: grinding ring in the use of this material, the durability is improved obviously. It is characterized by high hardness, good wear resistance, magnetic. Mainly used for product in powder processing of iron. The product after normalizing and tempering heat treatment, mechanical performance is improved greatly, make the product not only has good wear resistance, but also greatly improve the toughness.

The Mn13: compared with 65Mn, the grinding ring in the Mn13 material after casting, in life has changed. After the pouring of water toughening treatment. Water toughening treatment after casting with tensile strength, toughness, high plasticity and no magnetism. The grinding ring is more durable. Subject to severe shock and strong pressure deformation in the using process, surface hardening, and martensite formation, thus forming the wear surface layer high, while the inner layer to maintain excellent toughness, even wear very thin, can bear a larger impact load.

Raymond mill host another vulnerability is grinding roller, under normal circumstances, Raymond mill for grinding roller in use for some time, this according to customer's materials, frequency of use and other factors to determine whether the operation. To limestone as an example, if the same operating conditions, the quality of the grinding roller but hard, then there will be excessive wear, the service life is greatly reduced. As a result, mill roll material is also one of the most important factor in deciding the quality of equipment manufacturers of Raymond mill.

Impulse dust removal equipment is configured for loading, grinding, finished product transportation and storage, to ensure that the production site is clean and environmentally friendly, and there is no dust pollution.

After signing the order, formulate detailed plans for production, preparation and delivery, basic production, and engineer dispatch, installation and commissioning, to ensure that the entire link is carried out in an orderly and efficient manner, and the final delivery is guaranteed.
