The "Pengfei" roller press is the latest generation of grinding equipment developed and researched by Jiangsu Pengfei Group Co., Ltd. It greatly reduces the energy consumption and noise of the pre grinding system, is suitable for new plant construction, and can also be used for technical transformation of old plants, increasing the output of the ball mill system by 30-70%

　　Process characteristics

　　After extrusion, 0.08mm fine particles account for 20-35% of the material cake, while those smaller than 20mm account for 65-85%. The internal structure of small particles is filled with many small cracks due to extrusion, greatly improving their grindability. The roller surface adopts hot welding, making the maintenance of the wear-resistant layer more convenient. Achieve a significant increase in output with extremely low energy consumption and operating costs. The roller press is widely recognized as the most advanced grinding equipment in the world due to its significant energy-saving (20-50%) and production increasing (30-70%) advantages. Jiangsu Pengfei Group has independently developed and designed various specifications of roller presses based on foreign experience and the actual situation in China, forming a series of roller press products that can meet the supporting needs of 50-1500t/h production lines, reaching the current international advanced level. The market share of roller presses has reached over 30%, and has achieved good results in use.

　　Technical Description

　　The "Pengfei" roller press adopts a roller press based on material layer grinding technology and a matching powder selector that integrates dispersion, grading, and drying in the grinding system. It can be combined with ball mills or form its own system to form various process flows, such as pre grinding, mixed grinding, semi final powder grinding, and final grinding systems. Due to changes in the grinding mechanism, the "Pengfei" roller press and its system technology can reduce power consumption and increase production in the grinding system; Suitable for grinding systems in newly built or renovated factories, and changing the current situation of insufficient grinding capacity due to the adoption of new standards.

　　Process flow

　　Roller surface technology (welding materials, equipment, and welding processes) effectively reduces the generation and propagation of microcracks during the welding process, with high hardness (>HRC58) and toughness. The service life of the roller surface is over 8000 hours, and daily maintenance is simple.

　　Adopting aviation hydraulic technology, the hydraulic system of the roller press is extremely reliable.

　　The CLF series roller press hydraulic system, in conjunction with a complete automatic control system, can achieve load control of the main drive motor of the roller press; Control and automatic correction of left and right gap deviation between two rollers; Fault self diagnosis technology.

　　The matching VX or VXR powder selection machine integrates the breaking, grading, and drying of the aggregate cake, and has the characteristics of low operating cost and high operating rate.

　　The supporting automatic control system adopts fuzzy control principle and integrates components from world-renowned suppliers.
