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 an advanced grinding equipment internationally for 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.

Technological process

1. Roll 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 roll surface is over 8000 hours, and daily maintenance is simple.
2. Adopting aviation hydraulic technology makes the hydraulic system of the roller press extremely reliable.
3. The hydraulic system of the CLF series roller press, when combined 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.
4. 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 costs and high operating rates.
5. The supporting automatic control system adopts the principle of fuzzy control and integrates components from world-renowned suppliers.
