Description

Limestone is a common building material widely used in industries such as construction, engineering, and metallurgy. In order to meet market demand, limestone needs to be ground to obtain the required particle size and fineness.
It can be widely used in industries such as power, metallurgy, cement, chemical, non-metallic minerals, etc. It is mainly used for grinding and processing raw materials such as cement, clinker, desulfurization limestone powder in power plants, slag micro powder, manganese ore, gypsum, coal, barite, calcite, bauxite, etc.
Vertical grinding machine is a commonly used equipment, and the following is its process flow for processing limestone.

Firstly, after initial crushing, the limestone is transported to the feed inlet of the vertical mill. The vertical grinding machine has a large feeding port and a high-efficiency crushing device, which can crush larger block shaped limestone particles into smaller particles, preparing for subsequent grinding.
Next, the crushed limestone particles enter the grinding chamber of the vertical mill. This grinding chamber is equipped with a set of grinding stones or grinding discs that grind limestone particles through rotation and rolling. The grinding chamber of the vertical grinding machine is also equipped with a grading device, which can separate fine powder and coarse powder by adjusting the device parameters according to the required powder particle size. During the grinding process, the vertical grinding machine takes limestone particles out of the grinding chamber through a negative pressure fan. The function of the fan is to generate negative pressure, introduce limestone particles into the airflow, and transport them to the classifier. In the classifier, finer powder is carried into the dust collector by the force of the airflow, while coarser particles are further ground and returned to the grinding chamber to obtain finer powder.
Later, the powder processed by the classifier and dust collector is transported to the storage equipment or packaging device. According to actual needs, limestone powder can be stored, packaged, and sold.

Limestone Vertical Roller 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.
