ultrafine grinding is currently the preferred equipment for milling

SHANGHAI SHIBANG MACHINERY CO., LTD is one high-tech enterprise, which involves R&D, production, sales and service as well. In the past 20 years, we devote to producing mining equipments, sand making machines and industrial grinding mills, offering expressway, rail way and water conservancy projects the solution of making high grade sand and matched equipments.

After the ultra-fine-grinding crusher crushes to the required particle size, the material is sent to the storage hopper by the elevator, and then the material is evenly and quantitatively fed into the main grinding chamber for grinding by the electromagnetic vibrating feeder, and the material after the grinding is blown by the fan. The airflow is sent to the classifier for grading. Under the action of the classifier impeller, materials that do not meet the fineness requirements fall into the ultrafine mill and are re-grinded. The materials that meet the fineness requirements enter the cyclone collector with the airflow through the pipe. Separation and collection, discharge through the discharge device is the finished powder.

The separated airflow enters the fan through the return duct at the upper end of the cyclone collector. The super-fine grinder belongs to the closed-loop circulation system and operates under positive and negative pressure. Since the milled material contains a certain amount of moisture, it is generated during grinding. The heat will cause the gas inside the mill chamber to evaporate and expand and change the system’s air flow, plus the sealing problem at the feed inlet and the junction of the pipes. The entry of outside air will make the air flow in the system out of balance. For this purpose, The exhaust valve of the fan outlet vents the excess gas into the bag filter and discharges it after purification. The system can achieve environmental protection while adjusting the air balance of the system.

Ultra-fine grinding and the base completely soft connection, no rigid contact, avoiding the vibration inside the grinding chamber to the middle body, the analyzer, the selection of high precision, the use of frequency control, than the electromagnetic speed control, speed control precision , process control flexibility, high degree of automation. Ultrafine grinding operation with high stability The base uses high-strength, anti-vibration crack ductile iron – ductile iron has cast iron vibration damping properties, cast steel strength and good impact resistance, the use of domestic imitation Germany Flander reducer, Make full use of professional reducer manufacturers technical manufacturing advantages, improve the stability of the whole machine. ultrafine grinding reducer and motor use V-belt transmission power, which is conducive to overload protection.

Ultra-fine grinding stability, equipment layout with the same resistance program, a wide range of applications, analysis and the use of frequency control and high-density blades, high environmental protection level, the powder collector two material outlet and dust collector discharge port three in one Line layout, first of all, we currently use advanced domestic and foreign technology of ultra-fine mill design, combined with our many years of experience, quality clearance. The components of the ultra-fine pulverizer are closely linked, easy to use, and can achieve our goal more quickly. The economical, reasonable price, small size, small vibration, low noise, energy saving and environmental protection are the preferred equipment for the current milling.
