Raymond Mill for sale in India
R-type Raymond mill (Raymond Swing) After years of practice and continuous improvement, its structure has been improving. Because widely used in the grinding process metallurgy, building materials, chemicals, mining minerals in areas such as materials, suitable for processing the following seven Mohs hardness, humidity, Raymond Mill for sale in India, various non-explosive ore below 6%, such as gypsum, talc , calcite, limestone, marble, feldspar, barite, dolomite, granite, kaolin, stone, bauxite, iron oxide red, iron ore, finished fineness 613 microns to 44 microns (0.613 mm -0.044 mm) between the machine and by analyzing the joint action fans can meet different user requirements.
1.Systematic, high-pass sieve
The whole three-dimensional structure, small footprint, systematic, from raw materials to delivery to rough milling and final packaging, of an independent production system. Finished powder fineness uniform rate of 99% through sieve.
2.Smooth transmission, high abrasion resistance
Machine adopts airtight gearing and pulley gear box, transmission smooth, reliable operation. Core components using high-performance wear-resistant materials, high wear resistance, and cost savings.
3.Easy to control, easy to maintain

Structures and working environment:
Raymond mill the entire structure by the host, analysis machine, plumbing fixtures, blower, finished cyclone, jaw crusher, bucket elevator, electromagnetic vibrating feeder, electric control motors and other components. Which Raymond host from the rack, inlet volute, blade, roller, grinding ring, cover and motor. Raymond the entire work process (the process of grinding material): Large bulk materials by jaw crusher to the desired particle size, by the elevator to the storage hopper the material, and then sent via a uniform continuous quantitative feeder into the host indoor grinding mill, flour grinding after the child was taken away by the fan airflow. The analysis machine for classification, in line with the fineness of the powder will flow through pipes into the large cyclone collector, to separate the collection, and then the powder discharge pipe is finished powder. Airflow and then from the upper end of the large cyclone collector suction blower return air duct. This machine is a closed loop system throughout the airflow, and is under negative pressure state circulating.
Generate heat in the room when the mill is grinding because there is a certain moisture content of the material, grinding mill indoor gas evaporation leads to changes in the gas flow, as well as the whole of each pipe connections are not tight so that the outside air is inhaled, so air circulation flow increases, this is a positive By adjusting the fan duct and the host than to achieve a balance between airflow and excess gas is introduced into the small cyclone collector, the residual gas into the powder down the sub-collection, and finally by a small cyclone collector on the exhaust pipe section into the atmosphere, or introduced into the precipitator so empty gas purification.
Raymond hosts work process is driven by rotation of the central shaft gear, the upper end of the shaft is connected to the plum rack, rack mounted roller device and the formation of the swing pivot around its center of rotation is not only the country, but around the grinding ring roller revolution Meanwhile, due to the friction roller itself and rotation. Plum frame with the bottom of the blade system, its location in the lower roller, roller blade and with the transfer process between the material feeding roller shovel throw ring, forming a litter layer, layer of the material generated by the rotation of the roller outward centrifugal force (i.e., pressing force) of the material is crushed, i.e., thus achieve the purpose flour.
By analyzing machine and after two slow speed motor drive 60 on the turntable rotating blades to form a sub-classification of the role of powder. Speed is based on the speed of the blades finished powder Liaoduo size adjustment. When To obtain a more fine-grained powder midnight, we must raise the blade speed, so that the blades in contact with the powder will increase, so that undesirable powder will be thrown into the outer wall and the airflow from the leaves, coarse child because of the role of self-gravity to fall grinding chamber regrinding, qualified to be finished powder with the air leaves a large cyclone collector inhalation, after the child is separated from the air flow and powder, the powder will be collected.
Large cyclone collector Raymond mill mill on the performance plays a very important role when the powder will flow into the collector with a high-speed rotation when the state, with the powder will be separated air flow, air flow over the cone wall Shrink to move to the center cone at the end (from the natural gas stream length) to form a cylindrical rotating updraft, then the powder will fall collection was isolated. As the upward rotation of the core negative pressure state, so the collector demanding the lower seal, must be strictly separated from the outside air, otherwise the powder will be collected under the core flow will be taken away again, which directly affects the whole production, So the tongue plate collector with the bottom lock powder feeder, whose role is to separate the external positive pressure gas and vacuum gas collector, this is a very important part, if not installed locks or lock pink powder is sealed anastomosis loose powder will cause no less flour, seriously affecting the whole production.
Another: Raymond winnowing process: the material after grinding, fans will be blown inside the White chassis, blowing powder into the grinding chamber through the top of the analyzer sorting, fine through coarse material falls back into the grinding Room regrinding, fineness meet the specifications into the cyclone collector with the airflow, after collecting pollen tube after discharged is finished. Air flow from the return air cyclone collector upper end of the tube back into the fan, the air duct is circular, and the flow under negative pressure, air flow circulation path integral plus some discharged by the fan host intermediate exhaust conduit into the small cyclones collector. Purification.
