The tailings grinding mill machine design integrates the functions of grinding, powder selection and drying. Compared with other grinding equipment such as ball mill and Raymond mill, the tailing mill has high efficiency, energy saving, high powder effect, small abrasion, large drying capacity, convenient adjustment of product thickness, uniform particle size and easy control of chemical composition. Low noise, less dust, less metal wear, simple operation, easy replacement of wearing parts, simple system process, small floor space, and good comprehensive economic benefits, so the vertical mill has attracted much attention in the grinding industry. It has been widely used in calcite, electrolytic stone, talc, kaolin, manganese ore, phosphate rock, gypsum powder, zircon sand, and metal silicon.
Product performance characteristics:
The grinding machine is installed on the ground. The above ground part is 50% of the height of the traditional mill, which reduces the height of the plant and saves investment in the plant, which is more conducive to equipment maintenance.
The grinding roller bearing seal is a new type of sealing method, which realizes maintenance-free and oil-free. Eliminate the bearing into the powder, greatly reducing equipment maintenance costs.
The grading cavity adopts a floating structure, which can automatically lift and shift to reduce equipment resonance, reduce noise and improve maintenance convenience.
Innovative grinding ring and grinding roller design optimize the arc-shaped occlusion method. Compared with the traditional old-style Raymond mill, it reduces the falling speed of the material through the grinding zone, prolongs the crushing and pulverizing time, and has the Raymond mill. The machine has a wide range of feed particle size requirements and ultra-fine grinding machine with ultra-fine grinding function. The crushing, grinding and ultra-fine grinding are in one step, and the fineness can reach d90:10um.
The rotating arm type installation structure of the classifier avoids the resonance of the main machine and the classifier, reduces the vibration of the equipment, reduces the running noise, eliminates the investment of the lifting and maintenance tools, and opens the maintenance operation, which increases the convenience of operation.
The middle tangential cyclone type air inlet makes the material spirally rise in the pulverizing and classifying chamber, which is more conducive to coarse powder extraction, reducing fan energy consumption and reducing production cost.
The whole system runs under negative pressure throughout the whole process, without positive pressure zone. The production environment is extremely excellent. The dust emission concentration is better than the national standard to reach ≤30mg/m3.
The classifier adopts the German vertical classifier technology. The same particle size classification can reduce the motor speed by 50%, which improves the service life of the bearing and reduces the wear of the classifying turbine, prolonging the replacement cycle. The wind structure and the wind-grid inlet method make the structure wear-free. Through the combined adjustment of frequency conversion speed regulation and secondary air, the classification efficiency can be improved by 5-20%, and the particle size distribution is more concentrated.
Medium-pressure pulse cleaning bag type dust collector adopts sealing welding, and the total air leakage rate is <2%. The utility model has the advantages of small structure volume, large filtering area, long service life and suitable for ultrafine powder filtration. The total collection efficiency is above 99.99%, and the dust emission concentration is less than 30mg/m3, which is superior to the national standard and achieves environmental protection exhaust.
The induced draft fan provides power flow to the system and is connected by high-pressure centrifugal fan suction. Ensure that all links operate under negative pressure. No dust leakage.
