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.
Raymond mill is also called Raymond roller mill. It is a new type of high-fineness grinding mill with high efficiency and closed circulation, which can completely replace the cement ball mill. This kind of machine is commonly used in cement plant for raw materials fine grinding, such as limestone, coal, gypsum, etc. Under normal conditions, these materials Mohs hardness should not be greater than 9.3 and the humidity should be under 6%. AGICO is one of the Raymond mill manufacturers in China. The Raymond roller mill we produced has the characteristic of stable performance, strong adaptability and high-cost performance. Its finished product fineness is usually between 0.61 and 0.033 mm, which can meet the requirements of different users.
When materials uniformly and continuously enter the machine body, they will be transported to the middle of the grinding roller and grinding ring by scraper blades,and during the grinding process, the materials will be stirred repeatedly by them. The grinding roller is tightly pressed on the grinding ring under the action of centrifugal force so that the material is crushed into powder under the action of grinding pressure, and then entered into the analysis machine by the cycle wind of the blower. After that, the qualified materials will pass through the analysis machine and enter the classifier for separation and collection. Otherwise, they will be sent back to the grinding disc for further grinding.
AGICO Group is an integrative enterprise group. It is a Chinese company that specialized in manufacturing and exporting cement plants and cement equipment, providing the turnkey project from project design, equipment installation and equipment commissioning to equipment maintenance.
