Roller Press
1、 Equipment introduction
Roller press is a kind of grinding equipmentaccording to the principle of high-pressure layer pulverization, and adopts the work mode of single-grain pulverization. It is mainly composed of frame, roller system, hydraulic system, feeding device, control system, transmission system and so on. The roller system is divided into a movable roller system and a fixed roller system. The two roller systems rotate relatively gradually. The movable roller system can be horizontally moved on the frame guide rail by the pressure of the hydraulic cylinder to continuously feed the material between the two rollers. It is crushed and pressed into a cover to fall outside the machine. The wear-resistant protection technology of the roller surface forms a self-generated wear-resistant protective layer during use and has a long service life. The maintenance of the roller surface is simple, and low in cost. And, the roller sleeve can be replaced. The design concept of constant roll gap control in a certain pressure range and the optimized control technology of high-pressure roll load solve the problem of traditional roll presses due to material separation and current out-of-tolerance stop. While ensuring the extrusion effect of materials, it improves productivity and also brings economic benefits. The automatic control system based on the principle of distributed fuzzy control and integrated with high quality components of renowned international and domestic suppliers can be controlled remotely on-site or in the central control room. It is simple, stable, safe and reliable.
2、 Technical advantages
(1) Increase output: install the roller press in the cement grinding plant, the high pressure load is transmitted to the layer of the grinded material through the diameter of the double roller, most of the energy is used for the mutual extrusion between the materials. Most of the energy is used to squeeze the materials between each other. The heat energy is converted into the deformation energy of the material, which is deformed, and crushed. Fully utilize the potential of the cement grinding equipment, The output can be increased by 50-100%, and the total energy consumption can be reduced by 20% -30%and promote the production efficiency of the entire system.
(2) Reduce power consumption: If you grind materials with roller press, the material after rolling is not only greatly reduced in particle size, The Bond function index is significantly reduced too, which greatly improves the grinding. The unit power consumption and the total power consumption of the grinding system of the entire grinding system is significantly reduced Compared with the traditional grinding method, it can save 25-50% energy, and the annual electricity saving benefit is considerable.
(3) Investment saving: Compared with the tube mill, the roller press with the same production capacity requirements is simple in structure, small in size, light in weight, and takes up less work space, which can save civil engineering investment and facilitate the whole investment. In addition, the operation and maintenance of the roller press is also very simple.
(4) Good working environment: The material is continuously and squeezed and crushed in the roller cover, and harmful dust doesn’t spread. At the same time, the noise of the roller press is much smaller than the tube mill because no impact.
(5) Easy to develop: Traditional tube mills are limited by conditions such as processing, transportation, and heat treatment. The grinding system with roller press solves this kind of problem well. Turning the grinding system into a large-scale development has become a reality.
3、 Specifications and Parameters
The configuration parameters of the conventional roller press are as follows, and special parameters can be customized as per the requirement.
