HC1700, New Generation of Large-size Grinding Mill

Max feeding size: 30mm
Capacity: 6-25t/h
Fineness: 0.18-0.038mm

HC1700 Grinding Mill is a newly developed large-scale mill by Guilin Hongcheng. The equipment referenced the operating principle of pendulum mill and improved the swinging method. With out changing other parameter, the centrifugal grinding pressure increased about 35%. The contact area of roller and ring is improved, the output has 2.5 to 4 times higher than traditional R mills. Applied constraint turbine classifier, production fineness can be adjusted around 0.18-0.022mm (80-600 mesh). At the same time, gearing device and roller assembly sealing are also improved to increase operational reliability and to offer an easier maintenance. HC1700 has the advantages of high capacity, high efficiency, low investment and operation cost and low pollution, it is the best choice of large-scale powder processing.

1. Most popular model, reliable operation

(1) HC1700 Grinding Mill following the powder processing development trends, HC1700 Grinding Mill, with revolutionary and innovative technology, is designed by our engineers, it is the most popular equipment in powder processing industry. Over the years, the marketing shows that HC1700 is a reliable, low cost and low pollution equipment.

(2) Advanced and reasonable structure of unique swinging pattern (Patent No.CN200720081221.1), new spider-arm and pendulum roller device. The equipment operates in low vibration and low noise.

2. High efficiency, low cost

(1) Single machine capacity can reach 25t/h, equal to 6 sets of 4R mills, while the energy consumption is 1/4 lower. The development of HC1700 is the first revolution of large-scale Raymond Mill.

(2) Turbine Classifying System（Patent No.ZL201030143470.6）: The classifying system uses the turbine classifier featuring in higher production capacity and more efficient classifying, which can make powder with a precise fineness ranging enlarge from 80-325mesh to 80-600mesh and ensure the highest passing rate.

(3) Equipped with pendulum roller structure. Compared with the traditional Raymond mill, more raw material can be ground per unit time, and the capacity is 40% higher than traditional Raymond mill with the same power consumption. 305 power can be saved for producing one ton powder.

(4) 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.

(5) 20-30dB lower noise than ball mill.

3. Easy maintenance, low operation cost

(1) 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.

(2) 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.

(3) Applied high quality steel to produce important parts, applied high performance wear-resistance material to cast wear-resistant parts, so the whole equipment has high wear-resistant performance and long service life.

(4) Unique double belt drive device (Patent No.CN200820104043.4): Grinding mills are working in bad condition, large material or hard matter may cause damage to the reducer and lead to long time maintenance. But the double belt drive has simple structure and is able to offer reliable operation and easy maintenance.

4. High cost 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.

Note: 1.The Models above can be equiped with Hongcheng patented certical pendulum sturcture,suspension pendulum structure is also avaible to material character
　　　　　　and product fineness.

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