Calcite grinding process

Calcite powder processing is generally divided into calcite coarse powder processing (0-3MM), fine powder processing (20 mesh-400 mesh), and ultra-fine powder processing of calcite (400 mesh-1250 mesh) and fine powder processing (1250 mesh-3250 mesh).

• First: broken

The large calcite material is crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.

• Second: milling

The crushed calcite pieces are sent to the silo by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the vibrating feeder for grinding.

• Tthird: classification

The ground material is classified by the classifier, and the unqualified powder is classified by the classifier and then returned to the host for re-grinding.

• Fourth: collecting powder

The powder that meets the fineness is separated and collected in the dust collector through the pipeline through the airflow. The collected product powder is sent to the finished product silo through the discharge port by the conveying device, and then is packaged by a powder tanker or an automatic baler.

The working principle of calcite powder grinder machine

When working, the main motor of the grinding equipment drives the main shaft and the turntable to rotate through the reducer, and the roller pins on the edge of the turntable drive dozens of grinding rollers to roll in the grinding ring raceway. The calcite raw mineral material is crushed into small particles by a hammer crusher, and then sent to the storage bin by the elevator, and then sent through the vibrating feeder and the inclined feeding pipe to evenly send the calcite particles to the bulk tray on the upper part of the turntable . After three layers of loops are processed into calcite powder, the high-pressure fan sucks outside air into the machine through suction, and brings the crushed calcite powder into the classifier. After regrinding, the fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged by the discharge valve at the bottom of the cyclone powder collector, which is the final ultrafine calcite powder. The airflow with a small amount of fine dust is purified by the pulse dust collector and then passed through the fan. And muffler discharge.

Maintenance of calcite powder grinder machine

1. During the use of the pulverizer, there should be a fixed person responsible for supervision, and the operator must have a certain technical level. Before installing the pulverizer, the operator must have the necessary technical training to make them understand the principle and performance of the pulverizer, and be familiar with the operating procedures.

2. In order to make the mill normal, the "equipment maintenance and safe operation system" should be formulated to ensure the long-term safe operation of the mill, and the necessary maintenance tools, grease and corresponding accessories should be provided.

3. The pulverizer should be overhauled after a period of use. At the same time, the wearing parts such as the grinding roller, grinding ring, blade, etc. should be overhauled and replaced. The connecting bolts and nuts of the grinding roller device should be carefully checked before and after use to see if there is any looseness. , Whether to add enough lubricating grease.

4. When the grinding roller device of the calcite mill is used for more than 500 hours to replace the grinding roller, the rolling bearings in the roller sleeve must be cleaned, and the damaged parts should be replaced in time. The refueling tool can be a manual refueling pump and a grease gun.
