Guilin Hongcheng is a fly ash mill manufacturer with rich production experience. It has a complete set of different types of coal ash stone mill equipment that meets different production fineness and output. Different production line equipment can process different coal ash powder.

HC LARGE CAPACITY COAL ASH VERTICAL GRINDING MILL is a large-scale product based on the company's HC1700 vertical pendulum mill. This series of mills is a large-scale environmental protection mill independently developed by Guilin Hongcheng Mining Equipment Manufacturing Co., Ltd., covering 5 invention patents. The fineness range of coal vertical mill is between 38-180μm (80-400 mesh), which can meet the domestic industrial policy and the expanding demand for industrialized scale production, make up for the blank of my country's large-scale pendulum mill, and expand the pendulum mill The application field of the powder machine, whether in terms of production capacity or unit energy consumption, has greatly improved the user's equipment efficiency, and its technical level will be at the domestic advanced level.

This product is suitable for grinding activated carbon and other non-flammable and explosive materials with Mohs hardness below 7 and humidity within 6%.

Finished product size: 38-180μm

Production capacity: 3-90t/h

ADVANTAGES AND FEATURES                                                                                                                                                                                                                       

New type of spide-arm featured in compact structure. It can be maintained without disassembly, which save the maintenance time.		Adopt maintenance-free oil seal technology, screw seal and skeleton oil  sealmulti-layer barrier, limited to prevent dust from entering, can achieve add  lubri-cating oil per 500~800 hours, reduce the maintenance cost.
Unique high chromium alloy material technology, the use time is nearly 3 times of the industry standard.		Forced turbine classification technology. The particle size of finished products  can be adjusted infinitely between 80~400 mesh.
Off-line pulse dust collection system, dust collection rate up to 99.9%.

MILL STRUCTURE & WORKING PRINCIPLE                                                                                                                                                                                                   

HC coal ash grinding mill consists of mill system, classifying system, screening, collecting system and other components. The mill system adopts the structure of integral casting base, which can be used as shock absorbing foundation. The classifying system adopts mandatory turbine classifier structure and the collecting system adopts pulse collection.

WORKING PRINCIPLE & PROCESS

Power processing system technological process: raw material will be transport to semi-open shed by special vehicle, and then be shoveled into the crusher to be crushed into particles smaller than 40mm. The material particles will be raised to the storage hopper by the elevator and then be evenly sent to the main mill for grinding by feeder. The qualified fine powder will be classified and blew to the pulse dust collector as product and finally discharged from the dust collector. The product will be transported to powder storage. HC super large grinding mill has really high capacity so the product cannot be packed by hand-filling, the packing job is supposed to be done after the power be sent to storage tank.

COAL ASH STONE POWDER PRODUCTION PROCESS                                                                                                                                                                               

1. Crushing of raw materials

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

2. Grinding

The crushed small pieces of coal ash stones 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:

1. The Models above are equiped with newly designed spider-arm structure.

2. The capacity is for limestone powder, and specification is just a reference. The actual production depends on these materials being processed.
