A short Introduction to Roller Press

Roller press, which can be also called extruding mill and horizontal mill, is actually a new sort of cement grinding device which was formulated through the mid eighties. It truly is to substitute for ball mill

method whose power usage is substantial but efficiency is lower. It also has the merits of minimizing consumption of metal goods and noisy, which happens to be rather suitable to your construction of new factories along with the engineering update of previous factories. It boosts the output of ball mill method by 30% to 50%. The material cakes which have been extruded contain 20% to 35% fine materials whose diameters are only 0.08mm and 65% to 85% other materials whose diameters are smaller than 2mm. The interior constructions of the particles are full of cracks because of the pressure, so the grindability with the materials is drastically improved.

The major attributes of roller press

(1) It might make the grinding gadgets generate as much as they're able to. Normally speaking, the output could be increased by 30% to 40%, but the total vitality consumption is reduced by 20% to 30%.

(two) It's a compact framework, gentle weight along with a little measurement. Compared using the other grinding techniques acquiring the exact same productive functionality, roller pressure can save the investment drastically.

(3) It has a simple structure, occupies a modest area and might be operated and fixed conveniently.

(4) Compared with other grinding gadgets, roller press has less electricity ash and lower sounds, which may enhance the doing work problem.

The software of energy saving engineering to make use of roller press grinding cement


During the entire process of cement manufacturing, 60% to 70% electrical power intake of the unit product is spent in grinding raw resources, reliable fuel and cement clinker. So the grinding engineering system using ball mill as the leading gear must be modified, and also the one particular which features a superior efficiency, a complicated composition as well as a higher vitality utilization rate really should be taken. This system whose main attribute is adopting material layer crushing principle adopts vertical mill

and roller press (also referred to as extruding mill) as principal grinding products. The grinding system can help save 30% to 40% electricity and decrease the electrical energy usage of cement unit product by 20% to 30% by adopting saving energy grinding machine and the relating engineering. Roller press and extruding grinding technologies, which adopt modern material layer crushing principle, are to show the supplies which might be fed into your two rollers of roller press into compact and flat material cakes with lots of very small cracks on it underneath powerful stress. These cakes contain plenty of very small powder, which improves the grindability tremendously. The combination grinding method and semi-finished grinding system are created up of roller press and V kind grading machine hierarchical thrasher (or hierarchical thrasher). They adopt low tension and higher circulation technologies, which may not merely boost the output of grinding program significantly but in addition boost the service daily life of devices.
