Embodiment 1

[0069] Please refer to image 3 , 4 And the structural representation of 5 embodiment one. The low-temperature material crushing structure described in Embodiment 1 is set on the material crushing equipment to carry out low-temperature material crushing. The low-temperature material crushing structure shown in the figure includes a cutter capable of crushing materials and an air flow channel capable of introducing air flow. The knives are two crushing knives capable of relative movement, which include a fixed fixed knife and a rotatable moving knife. There is a gap between the moving knife and the fixed knife, and the material is crushed in the gap, so the gap Also called "crushing chamber", the working surface of the moving knife is parallel to the working surface of the fixed knife. The air flow channel is arranged on the crushing blades and communicates with the gap between the two crushing blades. Such as image 3 As shown, the shape of the crushing knife is disc, coni...

Abstract

A method for crushing low-temperature materials uses a material crushing device which comprises two crushing blades capable of moving relatively and an air flow channel communicated with a gap between the two crushing blades. The method comprises the following steps that: (1) the materials are sent into the gap between the two crushing blades; (2) the air flow passes the air flow channel and goes toward the working face of the crushing blades and the surface of the materials in an angle of incidence, and fills the gaps to form a jet air curtain layer; (3) the two crushing blades move relatively and crush the materials in the jet air curtain layer; and (4) the crushed materials are discharged from the gap with the air flow. By using an air-flow direct cooling way, the method effectively eliminates accumulation of crushing heat and static generated from friction, and prevents occurrence of melting and softening of the materials and degeneration and clustering, thereby meeting crushing requirements of high mesh and fine grain of the low-temperature materials. A structure for crushing low-temperature materials has advantages of large output, low energy consumption and high efficiency, and can be used for crushing the low-temperature materials with relatively low melting temperature, such as rubber, silicone, plastic, protein powder, herbal medicines, etc.

Description

technical field [0001] The invention relates to a material crushing method and equipment thereof, in particular to a process method and equipment structure for low-temperature material crushing, belonging to the technical field of material crushing and grinding. Background technique [0002] In order to reuse waste materials, people usually crush and grind waste materials into particles or powders of various sizes, and then put them into production as recycled raw materials, such as plastics and rubber. The crushing or grinding of materials generally adopts grinders specialized in processing recycled materials, such as: 280 plate grinder is a kind of material grinding machine with double discs, which can process waste materials into 40-120 mesh (0.38-0.12mm) at room temperature ) Fine rubber powder. As another example, the conical grinding head material pulverizer is a recycling material crushing equipment whose grinding head is a cone. Existing grinding machines are usual...
