Description

Crusher for solid < RTI ID = 0.0 >

The present invention relates to a solid crusher for crushing solid matter produced from sewage sludge or the like to be sufficiently combustible in a boiler.

The amount of sewage sludge generated each year due to population growth and industrial development is increasing day by day. Most of sewage sludge that is generated in this way depends on marine dumping. Recently, sewage sludge marine dumping is prohibited according to international agreement. And thus the processing thereof is becoming a problem both at home and abroad.

As a method for solving this problem, research and development of a method of using sewage sludge as a fuel in a coal-fired power plant after being dewatered to a solid material have been proceeded to practical use.

However, in order to be used as a fuel in a coal-fired power plant, it is necessary to sufficiently subdivide the coal and supply it in a state favorable to combustion. For this purpose, a pulverization process is essential, and recently developed Korean Patent Publication No. 10-2002-0035823 (Apr. 15. Disclosed) is being used.

However, the conventional grinding machines have problems such as frequent failure due to abrasion or breakage during use of a member such as a saw blade or a hammer mill knife, and actual grinding efficiency is remarkably lowered.
