Embodiment Construction

[0047] Refer below Figures 1 to 5C A crusher according to one embodiment of the present invention will be described.

[0048] figure 1 It is a front view showing the crusher 10 . again, in figure 1 shows a cross section when the crusher 10 is cut with a plane perpendicular to the axial direction of the rotor of the crusher 10 . The crusher 10 crushes the material by impacting the material thrown into the crushing space 14 inside the housing 18 from the inlet 11 formed in the housing 18 . The crushed material is discharged from the discharge port 12.

[0049] The crusher 10 includes a rotor 15 and a plurality of impact members 16 attached to the rotor 15 in a crushing space 14 inside a casing 18 . The impact members 16 are mounted on the rotor 15 at regular intervals along the circumferential direction of the rotor 15 . As the impact member 16, for example, a hammer is used. Such as figure 1 As shown, each percussion member 16 can also be mounted to the rotor 15 via a ...

Abstract

[Problem] To provide a pulverizer wherein the temperature of the inner surface of the liner can be efficiently adjusted. [Solution] The pulverizer (10) is provided with: a rotator (15); striking members (16) installed on the rotator (15) for colliding with brown coal (13); collision plates (20) disposed around the rotator (15); and liners (30) provided on the inner surfaces (21) of the collision plates (20) and having an inner surface (31) onto which brown coal (13) that has collided with the striking members (16) is thrown. The pulverizer (10) also is provided with a temperature adjustment mechanism (40) for adjusting the temperature of the inner surface (31) of a liner (30). The temperature adjustment mechanism (40) is configured so as to be capable of adjusting the temperature of the liner (30) further to the inside than the inner surface (21) of the collision plates (20).

Description

technical field [0001] The invention relates to a crusher for crushing coal and other materials, in particular to a crusher for crushing peat, lignite and other high-adhesion materials containing a large amount of water. Background technique [0002] In recent years, the consumption of energy resources in the world has grown rapidly, and the prices of oil, coal or natural gas, which are the main energy sources, are all rising. Therefore, how to efficiently utilize these energy sources has become an important issue. [0003] As coal used as fuel, bituminous coal with high calorific value is generally used. However, with the economic development of emerging countries, the supply and demand of bituminous coal is becoming tense worldwide. On the other hand, it is presumed that the reserves of low-rank coal represented by lignite, peat, or sub-bituminous coal are higher than the reserves of high-rank coal such as bituminous coal. Therefore, research related to efficient utiliz...
