Multi-functional-tooth-form integrated high-crushing-ratio type fine crushing machine

Abstract

A multi-functional-tooth-form integrated high-crushing-ratio type fine crushing machine comprises a machine body and two crushing rollers, wherein each crushing roller comprises a main shaft (8), a roller tooth plate (3) and a connecting bolt (7); and roller tooth plates (3) with the same quantity are mounted on the two main shafts (8) in a staggering distribution manner. The machine is characterized in that a plurality of groups of crushing teeth are distributed at uniform intervals on an outer cylindrical surface of each roller tooth plate (3); each group of crushing teeth comprises primary crushing teeth (4), cutting crushing teeth (5) and trapezoidal teeth (6); the primary crushing teeth (4), the cutting crushing teeth (5) and the trapezoidal teeth (6) are sequentially distributed; the crushing teeth on all roller teeth plates (3) on each main shaft are distributed in the same phase; the primary crushing teeth (4) are olecranon-shaped; edges of which the top angles are 55-65 degrees are arranged at the tail ends of the cutting crushing teeth (5); and an included angle between long edges of the trapezoidal teeth (6) and tangent lines of the cylindrical surfaces of the roller teeth plates is 45-55 degrees. The machine is compact in structure, reliable to work, high in production capacity in unit volume, and convenient to maintain.

Description

Technical field [0001] The invention belongs to the field of mechanical crushing, and relates to a crushing device, in particular to a fine crusher with a large crushing ratio integrating multiple functional tooth profiles. Background technique [0002] The full use of renewable resources is an important measure for my country to realize a circular economy, and waste electromechanical products contain a large number of renewable resources that can be recycled. Under normal circumstances, for the disassembled part, it can be remanufactured or directly recycled as raw materials; and for the difficult-to-disassemble part, it needs to be evenly crushed to a smaller size, that is, crushed to achieve fine sorting, and then achieve Efficient recycling of renewable resources of different materials. [0003] The roller crusher has become one of the main choices of crushing equipment for waste electromechanical products due to its simple structure, reliable work, and good comprehensive crus...
