CALCIUM CARBONATE HCH ULTRAFINE RING ROLLER GRINDING MILL
CALCIUM CARBONATE HCH ULTRAFINE RING ROLLER GRINDING MILL
HCH Calcium Carbonate ultrafine ring and roller grinding mill has comprehensive mechanical crushing properties such as roller crushing, grinding and impact, etc. It is widely used for ultrafine crushing of all kinds of non-metallic minerals, such as calcium carbonate and other non-metallic minerals with mohs hardness below 7 and moisture within 6%.
Hongcheng HCH1395 Calcium Carbonate ULTRAFINE RING ROLLER GRINDING MILL has been certified by China Carbonic Acid Association as the energy saving and consumption reducing equipment in the field of calcium carbonate superfine processing in China. It is also the super large ultrafine ring roller mill in China.
Finished product size: 5-45 μm
The production capacity is 1-22T /h
MILL STRUCTURE:
The complete system of HCH Calcium Carbonate ultrafine ring and roller grinding 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.
CALCIUM CARBONATE POWDER PRODUCTION PROCESS
1. Crushing of raw materials
The large pieces of Calcium Carbonate are crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.
2. Grinding
The crushed small pieces of Calcium Carbonate 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.

The broken ratio is big. Feeding non-metallic mineral particles with a particle size of <10mm can be processed into fine powder of <10μm (under the pass rate of 97%) at one time, and the fine powder of -3μm accounts for about 40%, with a large specific surface area. It has the advantages of high-speed impact mill to produce powder and low consumption, and it has the product fineness close to jet mill. |

Environmental protection. The pulse dust collection system (patent: CN200920140944.3) has a dust collection rate of over 99.9%, ensuring dust-free operation in the workshop. Thorough dust removal: The pulse dust collection system adopts a pulse-jet dust removal method, which uses compressed air to clean each filter bag separately. The cleaning kinetic energy is higher and more thorough, thereby preventing the long-term backlog of powder. The powder is on the filter bag for a long time. Retention and clogging of the filter bag. |
 |
Forced turbine. Forced turbine classification technology (patent: ZL201030143470.6), the finished particle size can be adjusted between 45μm and 5μm. |

Good performance.
The roller and ring are made of special wear-resistant steel, which has a long service life. The base is firm and has good shock absorption performance. |
