Raymond pendulum grinding mill for limestone / nonmetallic ore

Raymond pendulum mill for limestone /calcium carbonate/dolomite/ talc/nonmetallic ore

Product Description                                                                                                              

Product Application

HC-series Grinding Mill is a kind of newly-designed roller-type mill, featuring in higher efficiency, lower power consumption and much better performance than traditional raymond mill developed by our engineer. With 5 patents, the HC1500 grinding mill is widely used to grind almost any non-metallic minerals with Moh’s hardness below 7 and moisture below 6%, such as gypsum, kaolin, calcite, marble, talc, manganese, ceramic, etc. The fineness can be adjusted from 0.18mm(80 mesh) to 0.038mm(400 mesh). Not only can the HC1500 grinding mill live up to the national industrial policy and meet the needs of mass production, but also fills the gap of large-size mill in the mill industry. This kind of mill plays a leading role in grinding technology, production capacity and power consumption per ton. With a production capacity of 25T/H, the HC1500 grinding mill can replace all kinds of mill, especially suitable for large-scale powder-making industry such dolomite/limestone/calcite, and etc.

 Technical Advantages and Feature

1.     Unique swag style (Patent No: CN200720081221.1)

The traditional R-type roller device caused a skew angle between roller and ring working platform because the rollers are placed horizontally and roller device turn up when swag. And the HC1700 applied vertical roller device which throw away horizontal when swag. The centrifugal force of vertical device increased almost 35% when the central rollers of main mill swag so that the roller compaction and crush power are strength. Otherwise, it is better for powder crush and average wearing of grinding area because of the horizontal touch of roller and ring of the vertical device. At the end, to extend the service life of wearing parts.

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 80-200mesh to 80-400mesh and ensure the highest passing rate.

3. 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 millneeds lubrication each days. The newly designed sealing structure ensures the roller assembly works continuously for 500-800 hrs without lubrication.

4.The powered device of HC1500 grinding mill is reducer transmission:

Compact structure, high transmission efficiency; Separated from main mill, easy maintenance.

 As well as the internal of reducer is designed by helical gear, it can bear larger load. Also gear

processing is completed by our specialist working on special machine to ensure its machining precision and working life. 

5.The Inblock Casting Foundation Base:

It provides solid structure and perfect vibration absorption, which can avoid crack or damage of other components caused by the long-time vibration and separate structure between air-return box and base. Improve the machine reliability and durability.
