Display Cases of Hongcheng Grinding Mill Calcium Carbonate Powder Processing

Project location: certain calcium carbonate powder processing project in Guangxi province, China
Raw material: marble, calcite
Equipment: 2 sets of HC2000 Grinding Mill (325 mesh D90); 1 set of HCH1395 Ultra-fine Mill (800 mesh D97);
Date of installation: September, 2015
Capacity: HC2000: 38t/h; HCH1395: 7t/h--7.5t/h

HC2000 Grinding Mill is the incredible Hulk in non-metal mineral powder processing. The HC series mill is a really high efficiency, energy saving and environmentally friendly ultra-large grinding mill referenced Germany technology and applied multiple patents. The capacity can reach 90t/h and can full fill the national industry policy and large-scale industry producing requirement. The equipment fill the blank of large grinding mill in China, and extend the application fields of pendulum grinding mill. The HC Large-scale Grinding Mill has international advanced technology which largely increase efficiency. The mill is able to be the replacement of any other facilities, it has the best performance in large-scale powder processing of power plant desulfuation, manganese industries.

At present, Hongcheng HC Large-scale Grinding Mill has a wide application in more than one hundred enterprises of manganese, petrol coke, power plant desulfuation, talc, calcium carbonate industry.

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.

Numerous cases show that Guilin Hongcheng HC Series Grinding Mill and HCH Ultra-fine Mill have obvious advantages than foreign brands in calcium carbonate processing:

Advantages of HC Series Grinding Mill:

1. Frame style cast pedestal has stable structure and high shock resistance, it can also avoid cracking or damage of vibration.
2. Shock absorbing axle sleeve made from special rubber and wear-resistant material not only absorb the vibration, but also has long service time.
3. Compact, reasonable and reliable spider-arm structure, the grinding ring can be changed without tearing down, which can reduce maintenance time and avoid unexpected trouble.
4. The roll assembly works in high dust concentration environment. The lamination sealing of the traditional R type roller mill sealed bearings unreliable. While this proposal adopted with multi-layer blocking sealing structure which combined with the floating oil sealing technology, screw seals and skeleton seals to prevent dust going into the bearing. Keep the roll assembly working smoothly and durable. Vastly short the maintenance time. The traditional R type roller mill needs lubrication each 1-2 days. The newly designed sealing structure ensures the roller assembly works continuously for 500-800 hrs without lubrication.
5. Applied high efficiency turbine classifying technology, production fineness can be adjusted from 80 mesh to 600 mesh. At the same time, applied air sealing obstruct technology to improve efficiency and accuracy in powder classifying, ensuring the percent of pass.
6. Applied offline pulse dust collector or pulse-jet collector, high capacity of dust removing, long service time of filter bags. 99.9% of the powder can be collected. The sealing for the mill ensures no powder floating in the workshop, so the equipment is more suitable for high dust concentration and high moisture site.

Advantages of HCH Ultra-fine Mill

High efficiency and high output, low cost and no pollution:
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.

Reliable operation, easy maintenance
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.

Complete set, wide usage
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.

High cost effective, low investment cost
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.

Under the situation of depression, Guilin Hongcheng will increase R&D input and promote product upgrading, will achieve the future by high quality and fine service. Guilin Hongcheng offers the best equipment for customers and will overcome the 'winter of depression' with all customers.
