Guilin Hongcheng HCH Series Ultra-fine Mill has Obvious Advantages in Calcium Carbonate Industry

Along with the development of ring-roller mill, many calcium carbonate enterprises found that it has obvious advantages than other types of grinding mill. So, more and more customers choose ring-roller mill for calcium carbonate processing. According to acknowledge, over 90% of the enterprises equipped ring-roller mill for newly built modern calcium carbonate production lines. Especially, after Hongcheng HCH1395 Ring-roller Mill won the Best Energy-saving Equipment Prize in Hezhou Calcium Carbonate Annual Meeting, the ring-roller mill has become an important equipment of modern calcium carbonate processing.

With years' accumulation of experience in R&D, the HCH Ultra-fine Mill is a new ultra-fine pulverizing equipment designed by Hongcheng. This mill is widely used to grind any non-metal minerals with Mohs hardness below 7 and moisture below 6%, such as talc, calcite, calciumcarbonate, dolomite, bentonite, kaolin, graphite, carbon black, etc. This kind of mill is especially suitable for ultra-fine grinding.

HCH Ultra-fine Mill has four obvious advantages:

1. Reliable operation

1). Large reduction ratio, high usage of energy. Non-metal material under 15mm in size can be processed into micro-powder under 10µm in size (D97), 40% is 3µm fine powder, which has large specific surface area. The equipment has the advantages of high output and low cost, and can produce ultra-fine powder.
2). HCH1395 Ultra-fine Mill is the largest ring roller mill in China. With an output of 11t/h, the equipment break the problem of the large-scale producing of ring roller mill.
3). Lower energy consumption, no pollution. The equipment operates under negative pressure, installed with larger dust remover, offing a low dust environment; applied with semi-automatic control and special technology to improve capacity, the equipment is one of the lowest energy consumption ultra-fine mill.

2. High cost effective

1). Stable operation, the main mill has special and high performance classifying device. The production quality is high and has no large particle pollution. It is an ideal equipment in non-metal fine powder dry processing.
2). Grinding wheel and ring are cast by special wear-resistant steel, which has long service time. It also reduce the time and labor cost of maintenance.
3). Main mill pedestal applied single-casting structure, ensuring structural strength and lower the vibration.

3. High efficiency

1). The equipment organized a complete production system from material crushing, transporting, grinding to production collecting, storing and packing.
2). The main mill is installed with classifying system, production fineness can be adjusted. The equipment has wide application in producing fine powder of D97=3-8µm or normal powder of D97=10-40µm.

4. Wide usage

1). The mill is in stereo-chemical structure, which lower the floor space and construction cost;
2). The mill is applied in ultra-fine powder processing, the construction and operation cost is low but has high efficiency.
