LYH996 series intelligent ring roller mill is composed of variable frequency screw feeder, main machine, fan, classifier, hydraulic system, pulse dust collector, electrical control device and pipeline system. The main engine consists of upper and lower body, grinding roller, rotary disc and reducer. When working, the material enters the main engine quantitatively, evenly and continuously through the frequency conversion screw feeder above the main engine side. Under the action of centrifugal force of the fast rotating grinding plate, the material is thrown to the inner wall of the grinding plate, and the material is brought between the grinding roller and the grinding ring, and is rolled and crushed under the pressure of the oil cylinder outside the grinding roller. At the same time, the high-pressure and large flow air flow generated by the air supply system and the crushed powder are mixed into a high concentration air flow, which enters the classifier on the main engine for separation. The coarse powder that can not reach the fineness will be returned to the grinding plate for regrinding, and the qualified fine powder will be collected in the finished product collector with the airflow, discharged from the discharge port of the finished product collector, and then stored in the finished product warehouse through the lifting equipment.

1. There is a gap of 3-5mm between the grinding roller and the grinding ring. The roller and the ring never contact directly, and the wear of the roller ring is small. Therefore, the iron content of the milled material is low and does not lose white;
2. With hydraulic pressure, the roller loading force can be adjusted freely, which can adapt to the grinding of various materials. The hydraulic spring is set in the hydraulic system, which is stable and reliable and easy to maintain;
3. Using new technology, new wear-resistant materials, long life of wearing parts, grinding roller grinding ring service life of 6-8 years;
4. The particle size of the finished product is 400-1500 mesh;
5. The output of 1250 mesh calcium carbonate is as high as 1.5 T / h, and the power consumption can be reduced by about 30% compared with ball mill;
6. The operation noise of the equipment is small, the system is operated under negative pressure, and the pulse dust collector is used to discharge the dust up to the standard without noise and dust pollution.
