High-efficiency crushing device for building materials

Abstract

The invention discloses a high-efficiency crushing device for building materials. The crushing device comprises a vertical column, a base, a primary crushing mechanism and a secondary crushing mechanism, wherein the vertical column is fixedly arranged on one side of the base; the primary crushing mechanism comprises a first crushing box, one side of the first crushing box is fixed on the inner side of the vertical column, the top of the first crushing box is provided with a feeding port, and an inner cavity of the first crushing box is provided with two groups of crushing assemblies; and the secondary crushing mechanism is arranged below the primary crushing mechanism, the secondary crushing mechanism comprises a second crushing box, the top of the second crushing box is provided with a feeding port, an inner cavity of the second crushing box is provided with two groups of crushing stirring assemblies and one group of spiral stirring assemblies, the bottom of the second crushing box isprovided with a discharging port, the base is provided with a material collecting box, and the material collecting box is arranged right below the discharging port. The high-efficiency crushing device has novel structural design, can realize multiple crushing of a building thermal insulation material, and has high crushing efficiency.

Description

technical field [0001] The invention relates to the technical field of crushing devices, in particular to a high-efficiency building material crushing device. Background technique [0002] Building insulation materials include extruded polystyrene foam glass, foam concrete (foam mortar), chemically foamed cement board, polystyrene particle insulation mortar, mineral wool (rock wool), phenolic resin board, expanded perlite insulation mortar Intel inorganic active wall thermal insulation materials, etc. Mainly by taking measures on the building envelope to reduce the indoor heat of the building to the outside, so as to maintain the building's indoor temperature. [0003] Building insulation materials need to be crushed in the actual recycling process, but the current crushing device has a complex structure and low crushing efficiency, so it is necessary to improve it. Contents of the invention [0004] The object of the present invention is to provide a high-efficiency bui...
