Material layer extruding energy-saving grinding apparatus

Abstract

The invention discloses a material layer extruding energy-saving grinding apparatus, which comprises a suspending device, a cambered supporting plate, a lining plate, a lateral baffle plate, a pressure device, a roll shaft, a roll sleeve, a driving device, a feeding device, a discharging device and a frame, wherein an upper lifting lug of the cambered supporting plate is connected with a pin shaft on the frame through a joint bearing in the suspending device, while a lower lifting lug of the cambered supporting plate is connected with one end of the pressure device through a joint bearing in the pressure device; the other end of the pressure device is connected with the frame through the joint bearing and a bearing block thereof; the roll shaft is eccentrically mounted inside the cambered supporting plate and one end of the roll shaft is connected with the driving deice; a material grinding chamber is formed between the roll sleeve and the lining plate; the cross section of the material grinding chamber is shaped as sigma which is big in top and small in bottom; and the feeding device and the discharging device are fixedly connected to the frame, respectively. The material layer extruding energy-saving grinding apparatus is good in corrosion resistance and energy-saving; the design of pressure bearing parts and the selection of materials are implemented easily; and the feeding device is designed easily.

Description

Technical field [0001] The invention relates to a grinding equipment, in particular to a material layer extrusion energy-saving grinding equipment. Background technique [0002] At present, the grinding equipment used in metallurgy, mining, electric power, building materials and chemical industries mainly includes: tube mill, roller mill and roller press. Among them, tube mill is a kind of grinding equipment with very low energy utilization rate. The effective grinding work only accounts for about 3% of the total energy. Most of the energy is converted into heat and noise and wasted. With the rapid development of modern industry, energy The tension problem is becoming more and more prominent, so the tube mill has gradually become the backward grinding equipment; the roller mill and the roller press are all material bed grinding equipment, with high grinding efficiency, low energy consumption, small footprint, and compact structure. It has gradually been widely used in many indus...

Problems solved by technology

Among them, the tube mill is a kind of grinding equipment with a very low energy utilization rate. The effective work of grinding only accounts for about 3% of the total energy, and most of the energy is converted into heat energy and noise and is wasted. With the rapid development of modern industry, energy The tension problem is becoming more and more prominent, so the tube mill has gradually become the obsolete grinding equipment; both the roller mill and the roller press belong to the material bed grinding equipment, with high grinding efficiency, low energy consumption, small footprint, and compact structure. It has gradually been widely used in many industrial production grinding systems, but the disadvantage of the two is that it is not suitable for grinding materials with high abrasiveness; in recent years, the French FCB company has developed a new type of grinding extrusion equipment, HOROMILL mill, with a large diameter round The cylinder rotates on a special support (main movement), and the grinding shoes made of wear-resistant materials are installed on the inner surface of the cylinder, and the roller acts on the grinding shoes with additional pressure, driven by the cylinder to rotate (passive), so that the material The crushing completes the grinding process, but the mill cylinder bears relatively large pressure from the rollers, and the structural design and material selection still need to be improved. At the same time, the design of the feeding device is difficult due to the rotation of the cylinder
