Description

Technical Field

[0001] This utility model relates to the technical field of reclaimed rubber breaking equipment, and in particular to a reclaimed rubber breaking equipment. Background Technology

[0002] The existing patent publication number (CN207901464U) discloses a recycled rubber crushing device, including a housing with an inlet and an outlet at the top. The inlet is equipped with a detachable roller magnetic separator. Inside the housing, a set of rubber crushing blades and a set of cylindrical grinding wheels are arranged horizontally. The rubber crushing blades and grinding wheels are connected to a motor drive mechanism outside the housing via a transmission box. The rubber crushing blades are positioned above the cylindrical grinding wheels, and a collection area is located below the cylindrical grinding wheels. An inclined filter screen is provided between the cylindrical grinding wheels and the collection area. The side of the housing has an outlet and a return outlet. The outlet is located below the filter screen, and the return outlet is located above the filter screen. This utility model has a compact structure and sequentially performs magnetic separation, crushing, and grinding on waste rubber, resulting in thorough crushing. The processed rubber powder has a small and uniform particle size, which improves product quality and extends service life.

[0003] However, its structure cannot adjust the particle size of the sheared particles.
