Description

Single-transmission roller press for mountain stone in-situ crushing for construction of power station in mining area

Technical Field

The invention relates to the field of grinding equipment, in particular to a single-transmission roller press for in-situ crushing of mountain stones for construction of power stations in mining areas.

Background

Mine areas generally need a large amount of electric energy, and in order to meet the use requirements of the electric energy of the mine areas, special power stations are generally established in the mine areas and used for establishing auxiliary facilities of other power systems including voltage stations and the like. In the process of power station construction, a large amount of construction materials such as construction stones and the like need to be used. Since the stone is the least lacking in the mining area, the only thing that is lacking is the treatment device, so that this part of the stone cannot be directly utilized.

The roller press is also called an extrusion mill and a roller mill, is mainly used for rolling slag, cement clinker and the like into fine particles from large-particle substances, and can also be used for rolling stone in a mining area into a usable particle size. The roller press is divided into a single-transmission roller press and a double-transmission roller press, the single-transmission roller press and the double-transmission roller press have the same point that both the single-transmission roller press and the double-transmission roller press comprise a fixed roller and a movable roller, the two rollers have the same speed and are completely synchronous, the two rollers run oppositely, materials enter from an upper feeding port and are extruded by high pressure in a gap between the two rollers to be crushed. The difference is that the single-transmission roller press only transmits power by the fixed roller, the power consumption is low, the motion of the movable roller is transmitted by the fixed roller through the tooth system, the complete synchronization is achieved, the installed power of the double-transmission roller press is large, the energy consumption is high, the installed power of the single-transmission roller press is about 65 percent of that of the double-transmission roller press, and the energy-saving effect is better.
