Problems solved by technology

[0005] The known technology has the following problems: The pulverizer usually realizes the work of crushing materials by means of two rollers moving in opposite directions through differential gear transmission. The power consumption of the motor of this equipment comes from driving the reducer, gear pair, driving roller and slave Moving roller and material load, so the power consumption is large;
[0006] The big problem in the treatment of waste materials is that materials of different textures and particle sizes are mixed together. The speed of the driven roller in the known technology is usually fixed. When the pulverizer is working, the driven roller in a constant speed state is Driven by the differential gear, since the two rollers must operate at a certain differential speed ratio, when the load exceeds the allowable value, no matter how much material is, it must be forced to pass through the gap between the two rollers, which will cause the equipment to stop. When the load is too large When the deformation of the roll exceeds the allowable value of the elastic deformation of the roll, the roll will break

Embodiment Construction

[0024] The specific implementation, structure, features and effects provided by the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0025] see Figure 1-3 , a material pulverizer, including a power part 1, the power part is connected by a motor 11 through a first coupling 12 and a reducer 13, wherein,

[0026] A material crushing part 2 is composed of a driving roller 21 and a driven roller 22 arranged side by side on the main frame 20. The driving roller is connected with the reducer 13 through the second coupling 14, and the driven roller can rotate freely around the axis.

[0027] The moving roller is installed on the main frame 20 by means of a bearing, which is a self-aligning roller bearing, which can make the main shaft bear even force, drive smoothly, prolong the service life of the bearing, and facilitate installation and maintenance at the same time;

[0028] There is a preset gap 24 betw...

Abstract

A material breaking machine is composed of machine frame, speed reducer, power unit with motor linked with said speed reducer via the first shaft coupling, cooling system, and breaking unit consisting of hollow active and passive rollers parallelly installed on machine frame and communicated to said cooling system. It features that the gap between active and passive roller is preset to make the active roller to just drive the passive roller via the material to be broken.

Description

technical field [0001] The invention belongs to the field of material crushing equipment, in particular to a waste crushing machine for further processing tire blocks into rubber powder and separating the rubber powder from steel wires, and is especially suitable for further crushing rubber materials such as waste tires. Background technique [0002] In the crushing of waste materials, waste automobile tires are crushed as a whole to make tire blocks, which need to be further processed. The tire blocks are crushed and crushed into rubber powder by a material shredder, and the rubber powder is separated from the steel wire. [0003] Known technology such as the published Chinese patent CN200320102601.0, a kind of crushing of tough materials such as waste printed circuit boards, waste plastics, rubber and waste batteries, especially flat materials with good toughness, high hardness and not easy to bend The double-roller shear crusher is composed of a...
