Product overview: The product is a new type of cement energy-saving grinding equipment, based on the material layer grinding technology, by roller press, dispersion, classification, drying, powder selection of a grinding system, can be combined with the ball mill to form a variety of processes, such as pre-grinding, mixed grinding, semi-final grinding and final grinding and other systems. Due to the change of grinding principle, roller press and grinding system technology, the power consumption is reduced by 50-100%, and the output is increased by 100-300%; It is suitable for the transformation of the grinding system in new or old plants. After extrusion, the 0.08mm fine material in the cake accounts for 20-35%, less than 20mm accounts for 65-85%, and the internal structure of small particles is full of many tiny cracks due to extrusion, and the grindability is greatly improved.
Working principle of roller press
The roller press grinds cement clinker and brittle materials by applying huge pressure to produce micro-cracks in the material and also produces a large amount of fine material. For some types of feeds and end products, the roller press can have the function of final grinding, replacing the ball mill, doubling the grinding efficiency. More commonly, the PFG roller works in conjunction with the ball mill to pregrind or semi-finish the material, significantly increasing the output of the entire mill system and reducing energy consumption. When the rolled clinker is fed into the ball mill, the energy consumption required to produce the finished cement is greatly reduced compared to the clinker that has not been pre-treated by the roll press. Based on innovation, the PFG roller press is one of Pengfei's advanced and efficient working systems. This solution is extremely flexible, not only for new equipment installation, but also for technical upgrading. The PFG roller press is used for technical transformation and can increase production by up to 100%. When installed as new equipment, it can reduce energy consumption by 20-30% compared to conventional ball mills.
