Grinding Machine HD9720 Features:
1. Large grinding force: GYM9720 high-pressure mill grinding roller assembly uses high-pressure spring device to increase the grinding force. The grinding force of each grinding roller assembly can be increased by 500Kg on the original basis, which greatly improves the milling efficiency.
2. Large grinding area: Grinding height of grinding roller and grinding ring increased from 160mm to 200mm.
3. Large amount of shovel: use an enlarged blade to maximize the feed of material into the grinding roller and the grinding ring.
4. High classification accuracy: The use of ultra-large grading turbines has a high pass rate and a large air volume. Moreover, the end surface of the classifying impeller sealing blade and the sealing end surface of the powder discharging port form a palace seal, and it is not easy to form a short circuit powder, and the classification accuracy is high.
5. Double cyclone collector: The parallel double cyclone collector is used, the collection efficiency is up to 80%, and the collection efficiency is increased by 10% compared with the single cyclone collector.
Grinding Machine HD9720 working principle:
Firstly, raw material is crushed by jaw crusher to the size required, and then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind. After this, the ground stuff is carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The airflow system is closely sealed up and circulated under condition of negative and positive pressure.
