Limestone Grinding Vertical Roller Mill For Slag Coal Clinker Cement Pet Coke

Description

Introduction to Limestone Vertical Mill:
Vertical mill is an efficient, energy-saving, and environmentally friendly drying and grinding equipment widely adopted by Hefei Hengcheng both domestically and internationally. Based on years of practical experience, it is researched, designed, and manufactured. It integrates drying, grinding, powder selection, and transportation, and has advantages such as wide adaptability, high grinding efficiency, low power consumption, low wear, large drying capacity, convenient product fineness adjustment, simple process flow, low noise, low dust pollution, reliable operation, and convenient maintenance. In recent years, it has been widely used in many fields such as cement raw material and coal powder preparation, power plant coal grinding and desulfurization stone powder preparation, slag grinding, chemical industry bentonite and phosphate ore grinding, metallurgy industry, ultrafine grinding industry, and so on.

The HVM vertical mill is increasingly favored by users for its excellent quality, advanced process technology, good performance, and excellent service.
Limestone powder for desulfurization requires a particle size of 250 mesh or 325 mesh (45 μ m) 325 mesh limestone powder has better desulfurization effect.

Characteristics of HVM type vertical mill
(a) The HVM vertical mill is equipped with a slag discharge port on the lower shell, which allows difficult to grind foreign objects to be discharged from the machine at any time. After shutdown, all remaining materials can also be emptied.
(b) The grinding roller can be flipped out of the mill for maintenance with the help of a hydraulic flipping roller device, and replacing easily worn parts only takes three shifts, improving the operation rate of the mill.
(c) The curved plate sealing structure is used between the grinding roller and the shell, which has better sealing effect and durability compared to traditional structures.

Limestone Vertical Grinding Mill Working principle:

The electric motor drives the grinding disc to rotate through the reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the wind ring at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and the qualified fine powder is discharged with the airflow, Collecting in the powder collection device is the product. Materials containing moisture are dried during contact with hot gases to achieve the required product moisture.
