HC3000, Largest Pendulum Mill in Asia

Max feeding size: 40mm
Capacity: 10-90t/h
Fineness: 0.038-0.18mm

HC Large-scale Grinding Mill was developed on the basis of HC1700 Grinding Mill. 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.

1. Advance equipment, reliable operation

(1) HC Large-scale Grinding Mill is a new equipment developed by Guilin Hongcheng, it was appraised by famous experts. The equipment is international advanced and has the advantages of high capacity, low energy consumption, stable performance and environmentally friendly.

(2) Frame style cast pedestal has stable structure and high shock resistance, it can also avoid cracking or damage of vibration.

(3) Shock absorbing axle sleeve made from special rubber and wear-resistant material not only absorb the vibration, but also has long service time.

2. High efficiency, low cost

(1) Single capacity can reach 90t/h, honored as Asian largest pendulum grinding mill by experts. Break the choke point of traditional pendulum mill, able to replace any type of grinding mill. The equipment is the best choice for large-scale powder processing.

(2) 40% higher capacity than traditional Raymond mill, 30% higher than ball mill (under the same condition).

(3) Applied high efficiency turbine classifying technology, production fineness can be adjusted from 80 mesh to 400 mesh. At the same time, applied air sealing obstruct technology to improve efficiency and accuracy in powder classifying, ensuring the percent of pass.

(4) Unique feeding method ensuring evenly material distribution to increase grinding efficiency. Moreover, it will increase the capacity and reduce abrasion.

(5) Applied offline pulse dust collector or pulse-jet collector (Patent No.CN200820113691.6), 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.

(6) 20-30dB lower noise than ball mill.

3. Advanced technology, easy maintenance, low operation cost

(1) 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.

(2) Multi-layer blocking sealing structure（Patent No.CN200820113450.1）: 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.

(3) Applied high performance wear-resistance material to cast wear-resistant parts, offering high wear-resisting property and long service life. High-chromium alloy can be applied to deal with high power and high burden grinding task, in this way, the service life will have 3 times longer than industrial standard.

(4) Equipped with combined cover structure, the roller and ring can be replaced without removing other parts, offering an easy maintenance.

(5) Applied frequency control and can be operated by PLC, realized unmanned operation and save up label cost. Customers can also choose long distance intelligent monitoring system to control the operation state.

4. High coat-effective, low investment cost

(1) The equipment has strong systematic because it can organize an independent and complete production system of raw material crushing, transporting, grinding to production collecting, storing and packing. The grinding mill is in stereo-chemical structure, consume small floor space (1/3 floor space of 4R mill under same capacity), largely reduce construction cost.

(2) High applicability, need not to change any parts before processing different material or fineness.

(3) Lower investment cost than vertical mill under same capacity.
