Title: What is Powder Grinding Mill used for?
Tags: Powder Grinding Mill
Blog Entry: Powder Grinding Mill   is widely used in the grinding and processing of mineral materials in metallurgy, building materials, chemicals, mining and other fields. According to the fineness of the material to be ground and the fineness of the discharged material, the mill can be divided into a vertical pendulum mill, a high-pressure suspension roller mill, a high-pressure micro-powder mill, a straight-through centrifugal mill, and an overpressure trapezoidal mill There are six types of pulverizers, three-ring medium-speed pulverizer.    The pulverizer is composed of a host, an analysis machine, a blower, a finished cyclone separator, a pipeline device, and a motor.    High-pressure suspension roller mill    The main engine is composed of a frame, an air inlet volute, a blade, a grinding roller, a grinding ring, a cover and a motor. Auxiliary equipment includes jaw crusher, bucket elevator, electromagnetic vibrating feeder, electric control cabinet, etc. Users can choose flexibly according to site conditions.    working principle    After the material is crushed to the required particle size, the material is sent to the storage hopper by the elevator, and then the material is uniformly and continuously fed into the main grinding chamber of the Raymond mill by the vibrating feeder. The grinding roller swings outward due to the centrifugal force during rotation. , Is pressed tightly on the grinding ring, the shovel blade scoops up the material to be sent between the grinding roller and the grinding ring, and the crushing purpose is achieved due to the rolling of the grinding roller. The fine powder after material grinding is brought into the analyzer with the circulating air of the blower for sorting. The coarse material falls back to regrind, and the qualified fine powder enters the finished cyclone powder collector with the airflow and is discharged through the powder outlet pipe. That is the finished product. In the Raymond mill room, there is a certain amount of water in the material to be ground, which generates heat during grinding, vapor evaporates, and the pipeline connections of the whole machine are not tight, and external air is sucked in, which increases the circulating air pressure to ensure that the mill is under negative pressure. Working in the state, the increased air flow is discharged into the dust collector through the residual air pipe, and then discharged into the atmosphere after being purified.    Structure    1. Three-dimensional structure, small footprint, strong complete set, independent production system from block material to finished powder; 2. The fineness of finished powder is uniform, and the sieving rate is 99%, which is difficult for other milling equipment. Available; 3. The machine transmission device adopts a closed gear box and belt wheel, which is stable in transmission and reliable in operation; 4. The important parts are made of high-quality steel, and the wear parts are made of high-performance wear-resistant materials, and the whole machine has high wear resistance and operation Reliable; 5. The electrical system adopts centralized control, the grinding workshop can basically realize unmanned operation, and the maintenance is convenient.    Scope of application of the high-pressure suspension roller mill: The high-pressure suspension roller mill is used to crush non-flammable and explosive mines and metallurgy, such as barite, limestone, ceramics, slag, etc., with Mohs hardness not greater than 9.3 and humidity below 6% , Chemical, building materials and other industries for high-fine powder processing of more than 280 materials, and the particle size of the finished product is adjusted in the range of 80-425 mesh (the finest is 1000 mesh). The machine can produce 30-80 mesh coarse powder by adding special devices.    In the main machine of the high-pressure mill, a high-pressure spring with a pressure of 1000-1500 kg is fastened on the roller hanger. After starting to work, the grinding roller rotates around the main shaft, and under the dual action of the high-pressure spring and centrifugal force, it rotates close to the grinding ring. Its rotation pressure is 1.2 times higher than that of the Raymond mill under the same power condition, so the output is greatly improved. . When the material to be ground enters the grinding cavity, it is shoveled by a spatula and sent between the grinding roller and the grinding ring for rolling. The powder after rolling is brought into the analyzer with the circulating air of the blower, and the qualified fine powder enters the cyclone with the airflow The powder collector collects the finished product, and the large particles fall back to regrind. The circulating air returns to the blower to repeat the above process, and the remaining air enters the bag filter for purification. When the grinding roller and the grinding ring reach a certain degree of wear, adjust the length of the high-pressure spring to maintain a constant grinding pressure between the grinding roller and the grinding ring. So as to ensure stable output and fineness.    Our company not only has Powder Grinding Mill, but also many other products, such as Ultrafine Pulverizer Machine  , etc. Welcome to visit our company!
