Zhangjiagang vertical plastic mill manufacturers common problems in the use of mills:
I. Wear repair of mill rollers and disc liners
During the use of the mill roller body and the wear-resistant lining board, once there is a gap between the body and the lining board, the wear between the body and the lining board will be aggravated. In addition, hot air and cement particles will constantly wash the mating surface, resulting in the occurrence of grooves. , Resulting in an impact collision between the body and the lining plate, in severe cases, the lining plate may crack or even break, and the machine may be damaged, especially the reducer, causing a vicious event.
Once such problems occur, general repair methods are difficult to solve, and replacement costs are high. The excellent mechanical properties and good plasticity of polymer composites make this problem solved.
Wear repair of the bearing room of the mill roller
The assembly requirements of the mill roller bearing are relatively strict. Enterprises generally adopt the method of placing the bearing in dry ice to cool it. Once there is a gap between the bearing and the bearing chamber, it will affect the normal operation of the bearing, cause the bearing to heat up, and in severe cases will cause the bearing to burn. Fushilan technology is fast, simple and easy to operate, and in many cases can be repaired in the field.
3. Leakage treatment of mill reducer
Leakage of the reducer of the mill not only affects the appearance of the machine, but also wastes oil products, causing great trouble to the equipment maintenance. 25551 fast curing material and 3223 rubber repairing material can be used to treat the leakage on site without stopping the machine. The operation is simple and the treatment effect is good.
Zhangjiagang Jianuo Machinery Co., Ltd. specializes in the production and development of plastic mill rotors and disc blades. The PVC rotor blades are made of high-speed wear-resistant steel, and the rotors of vertical high-speed mills are forged parts and high-speed. Dynamic balance test, high processing accuracy, good wear resistance, no residual dead angle, durable, can be used on both sides alternately with a size of 145 * 90 * 10 * center hole 90mm, all models are used together, and it is easy to disassemble and install.
After the material is pulverized to the required particle size, the material is sent to the storage hopper by the hoist, and then is evenly and continuously fed into the grinding chamber of the main unit of the Raymond mill by the vibrating feeder. Due to the centrifugal force during rotation, the grinding roller swings outward , Pressed tightly on the grinding ring, the blade scrapes the material and sends it between the grinding roller and the grinding ring, which achieves the crushing purpose due to the rolling of the grinding roller. The fine powder after material grinding is taken into the analysis machine by the circulating air of the blower to be sorted. The material with excessive fineness falls back to the regrind, and the qualified fine powder enters the finished cyclone powder collector with the air flow and is discharged through the powder outlet pipe. That is the finished product. In the Raymond mill, there is a certain amount of moisture in the material being milled. During the grinding, heat is generated, water vapor is evaporated, and the pipes of the whole machine are not tight. Outside air is sucked in, which increases the circulating air pressure and ensures 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.
Structural characteristics of plastic mill manufacturers
1.Three-dimensional structure, small footprint, strong package, independent production system from block material to finished powder;
2. The fineness of the finished powder is uniform, and the pass rate is 99%, which is difficult for other milling equipment.
3. The transmission of the machine adopts a closed gear box and a belt wheel, with stable transmission and reliable operation;
4. Important parts are made of steel, wear-resistant parts are made of high-performance wear-resistant materials, the whole machine has high wear resistance and reliable operation;
5. The electrical system adopts centralized control, the milling workshop can basically realize unmanned operation, and the maintenance is convenient.
