ADVANTAGES AND FEATURES                                                                                                                                                                                                        

The frame-type integral base has a solid and reliable structure and strong anti-vibration ability. It avoids the cracking or damage of other components caused by long-time working vibration and fatigue of the split structure of the air return box and the base, and improves the stability and reliability of the  equipment operation.		The shock-absorbing shaft sleeve made of  rubber and wear-resistant materials not only  effectively isolates the vibration generated by  the operation of the equipment, but also changes the short service life and frequent maintenance defects of the rubber sleeve structure used in the old Raymond mill, ensuring production continuity.
The special feeding method allows the raw materials to be evenly distributed in the mill, which improves the rolling rate, which is more conducive to the crushing of the powder, the grinding area wears evenly, and the service life of the wear-resistant parts is prolonged.		The new structure of spider-arm is compact, reasonable and reliable. The grinding ring can be updated without disassembling it, reducing maintenance time and avoiding additional failures caused by the previous Raymond mill’s quincunx structure.
Using unique wear-resistant high-chromium alloy material technology, it is more suitable for high-frequency, heavy-load collision and rolling conditions, and the service life is nearly three times longer than the industry standard.		The combined hood structure makes it simpler and more convenient to maintain and repair without disassembling other parts when the grinding roller is worn out.
The classifier adopts large-scale forced turbine classification technology, which has large processing capacity and high classification efficiency. The particle size of the finished product can be adjusted between 80-400 mesh. At the same time, it can adopt air-sealed barrier technology with high classification accuracy to ensure the qualified rate of fineness.		The off-line dust cleaning pulse dust collection system or residual air pulse dust collection system is adopted, which has a strong dust removal effect, a long service life of the filter bag, and a dust collection efficiency of up to 99.9%. It is more suitable for dust collection conditions with high dust concentration and large moisture.
Multi-layer barrier structure is used to ensure the sealing of the grinding roller device (patent number CN200820113450.1): The working environment of the grinding roller device is high dust concentration, and the grinding roller device of the traditional R-type pendulum mill cannot be reliably sealed by stacking. For bearing sealing, the grinding roller assembly needs to be oiled and maintained every day. The HC large-scale pendulum mill adopts maintenance-free oil seal technology, spiral seal and multi-layer barrier structure of skeleton oil seal, which can effectively prevent the entry of dust and maintain the normal working condition of the grinding roller assembly. It can be refilled every 500-800 hours. Grease greatly reduces equipment maintenance time and maintenance costs.

MILL STRUCTURE & WORKING PRINCIPLE                                                                                                                                                                                       

The HC pendulum mill system is composed of a grinding host, grading and screening, product collection, and other components. 

The host adopts an integral casting base structure and can adopt a shock-absorbing foundation. The classification system adopts a mandatory turbine classifier structure, and the collection system adopts pulse collection. The process flow of the pulverizing system: the raw materials are transported by a special vehicle to the semi-open raw material shed, and then shoveled by a forklift to the lower hopper, crushed by a crusher to less than 40mm, and the material is lifted by a hoist to a storage hopper in front of the mill; When the material is discharged from the hopper, the material will be evenly sent to the host by the feeder for grinding. The qualified products in the grinding process are classified and screened by the classifier, and then enter the pulse dust collector through the pipeline. After being collected by the pulse dust collector, the products are discharged through the discharge port at the lower end of the pulse dust collector. Unified delivery to the powder storage bin. This system is designed as an open-circuit system, the dust collection is full pulse collection, the pulse collection efficiency is 99.9%, the output of the mill will inevitably increase, and it is more environmentally friendly. For the finished product, the user can perform the next set of procedures for deep processing according to the actual process. The single unit of HC large-scale mill has a large output, which cannot be packed manually, and must be transported to the powder storage tank before packaging.
