Researchers of Pyongyang University of Mechanical Engineering have recently developed a new high-performance hammer crusher.

Such a crusher is widely used in the mining industry and various other sectors of the national economy as it is simple in structure and high in crushing effect.

Generally, there are two kinds of hammer crushers: horizontal and vertical ones.

A horizontal hammer crusher has a wide application for its simple structure and easy operation, but its sieve is often blocked during its operation, decreasing its utilization rate, and the utilization rate of crushing space is low.

Meanwhile, the vertical one is high in energy efficiency as its outlet is never blocked. But its structure is complicated, so it is difficult to disassemble and assemble it for maintenance.

Therefore, the researchers set a goal of developing a high-performance crusher free from such demerits and conducted research to that end.

In the course of this, they conceived of a kind of hammer crusher with a unique structure unlike horizontal and vertical ones, channelled efforts into optimizing the design of all its parts and properly solved different technical problems including those of using no sieve and preventing the bearing section from being dusted.

All parts of the hammer crusher are installed at an oblique angle.

While rolling round the axis of the crushing cylinder installed at an oblique angle, raw materials are hit and crushed by the crushing hammers at different levels.

The hammer crusher, which is high in crushing capacity and easy to repair, was registered as a practical technology patented one as it is widely used in different sectors of the national economy.
