INTRODUCTION OF PRODUCT                                                                                                                                                                                                                         

Quartz stone is processed by a sand making machine and a jaw crusher to become quartz sand. Quartz sand is an important industrial mineral raw material. After being finally ground by a mill, it can reach a fineness of 20 mesh to 1000 mesh or even higher. It is widely used It is used in industrial production fields such as glass, casting, ceramics and refractory materials, metallurgy, construction, chemical industry, plastics, rubber, abrasives, etc.

HCH easy-maintainable superfine quartz powder production mill line is a new type of high-fine grinding equipment newly developed by Guilin Hongcheng accumulated years of production and R&D experience. The product fineness can be adjusted between 325 mesh and 2500 mesh according to needs, and the product fineness can be adjusted once. The performance can reach D97≤5um. This machine has comprehensive mechanical crushing properties such as roller compaction, milling, impact, etc., and is widely used for high-fine crushing of various non-metallic minerals with Mohs hardness below 7 and humidity within 6%, such as activated carbon. HCH2395 is currently the larger high-fine ring roller mill in China.

Finished product particle size: 5-45μm (325-2500 mesh)

Production capacity 1-22t/h

The complete system of HCH superfine quartz powder mill is mainly composed of main machine, feeder, classifier, blower, piping device, storage hopper, electric control system, collection system, etc.

WORKING PRINCIPLE                                                                                                                                                                                                                                      

The grinding roller mounted on the rotary table in the main machine chamber rotates around the central axis, and there is a large gap between the grinding roller and the grinding roller pin. Under the action of centrifugal force, the grinding roller swings horizontally outward, so that the grinding roller compacts the grinding ring, and the grinding roller rotates around the grinding roller pin at the same time. Through the gap between the grinding roller and the grinding ring, the material can be crushed and ground by the grinding roller. The grated powder falls to the chassis under the action of gravity and is blown to the classifier above the main engine for screening under the action of a blower. The air path is circulating, except for the positive pressure from the blower to the grinding chamber, the gas in other pipelines flows under negative pressure. The material contains water, which evaporates into gas when it is heated during grinding. The air entering into the gas at various joints in the pipeline leads to the increase of the air volume in the circulating air path. The increased air volume is discharged into the atmosphere through the bellows interface between the blower and the main engine.

QUARTZ POWDER PRODUCTION PROCESS                                                                                                                                                                                                   

1. Crushing of raw materials

The large pieces of quartzs are crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.

2. Grinding

The crushed small pieces of quartzs are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the feeder for grinding.

3. Classification

The ground material is classified by the classification system, and the unqualified powder is classified by the classifier and returned to the main engine for re-grinding.

4. The collection of finished products

The powder that meets the fineness is separated and collected in the dust collector through the pipeline through the airflow. The collected finished 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.

Note:

The capacity is for calcite powder(feeding size ≤10), and specification is just a reference. The actual production depends on these materials being processed.
