Abstract

The invention provides a double-shaft differential type crusher. In the prior art, in a double-shaft differential type crusher, chromium-molybdenum steel having excellent strength property is employed to work as disc type cutter material. However, the chromium-molybdenum steel corrosive, so the surface of the disc type cutter is corroded when used in corrosive environment such as a sewage processing factory and sliding surface wear is caused. To solve the above problems, impurities in the water can be crushed by the use of the double-shaft differential type crusher. The double-shaft differential type crusher is characterized by comprising a driving motor, a driving shaft driven by the driving motor, a driven shaft driven by rotation of the driving shaft, and a ceramic cutter equipped to the driving shaft and the periphery of the driven shaft.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2014-106897 filed on May 23, 2014. The entire contents of this Japanese application are incorporated herein by reference. technical field [0002] The invention relates to a double-shaft differential crusher for crushing inclusions in water. Background technique [0003] In sewage treatment plants, etc., there is a problem that impurities such as residues clog pumps or dehydrators and other equipment. Therefore, a crusher for crushing inclusions such as slag is installed in the front stage of these equipments. In addition, in the process of cleaning foreign matter such as residue, a crusher is used in order to improve the cleaning effect of foreign matter. [0004] For example, Patent Document 1 describes a dual-shaft differential crusher, which is used for crushing and cleaning residues recovered in sewage treatment plants in a treatment system for residues. In this twin-shaft differential c...
