What Is The Difference Between a Roadheader And a Shearer?

With the development of the coal industry, its function is more and more, and its structure is more and more complex. It is defined as the machine that rotates the working mechanism to break the coal and load it into the conveyor or other transportation equipment. Therefore, the Roadheader manufacturers gave us an analysis of the difference between the boring machine and the coal mining machine, let's take a look at the following.

Shearer(Coal Roadways Rock Loader) is a large and complex system integrating machinery, electricity and hydraulic pressure. The working environment is harsh. If there is a fault, it will lead to the interruption of the whole mining work, causing huge economic losses. It is divided into planing, sawing, milling and drilling four types:

(1) planer shearer is planer, planer by the reciprocating motion of the plane cutter planer broken coal;

(2) sawing shearer is coal cutting machine, by installing in the circular movement of the chain cut teeth deep into the coal wall coal cutting;

(3) milling shearer according to the characteristics of the force of the coal wall and mechanical characteristics, make full use of the coal rock tensile strength of the weakest of this mechanical characteristics, the use of parallel working face of the coal wall of the tool for the coal body, so that the tool contact with the coal body after the impact of the impact of the tensile stress in the coal body, so that the coal cracking falling of a mining device;

(4) drilling shearer drill into the coal by the edge of the bit cutter teeth, by the middle of the broken coal cutter teeth will be broken in the middle of the coal.

Roadheader is divided into open type roadheader and shield type roadheader. Prices are usually in the hundreds of millions of yuan. It is mainly composed of walking mechanism, working mechanism, loading mechanism and transferring mechanism. As the walking mechanism advances, the cutting head in the working mechanism continuously breaks the rock and carries away the broken rock. It has the advantages of safety, high efficiency and good quality of roadway.
