Abstract

The invention relates to the technical field of crushing, in particular to an energy-saving and environment-friendly crushing device for construction engineering. It includes a shell, a first endless filter belt, a first crushing assembly, a second endless filter belt, a second crushing assembly, and a discharge belt. The shell is provided with a first transmission device and a second transmission device arranged up and down. Driven by the transmission device, the two filter belts rotate in opposite directions, and the upper part of the two filter belts is tensioned, while the lower part is loose, and they are arranged obliquely in opposite directions. In the present invention, the material is sieved through the first annular filter belt first, and then enters the first crushing assembly for primary crushing; after coarse sieving and primary crushing, the material is sieved by the second annular filter belt, and then Enter the second crushing component for secondary crushing; through the crushing process combined with screening, crushing and graded crushing, the over-grinding phenomenon caused by re-crushing the qualified materials is avoided, and the screening effect and the rational use of equipment are improved. rate, energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of crushing, in particular to an energy-saving and environment-friendly crushing device for construction engineering. Background technique [0002] The role of the crushing device is to decompose large particle materials into small particle materials that meet the required particle size by means of extrusion, rolling, beating, vibration, etc., to meet the needs of production and life. Most of the existing crushing processes adopt the method of graded crushing. Firstly, the crusher is used to roughly crush the material, and then the coarsely crushed material is put into the coarse-toothed roller crusher for crushing, and then the material is put into the fine-toothed roller crusher. Crushing is carried out to finally obtain the desired fine particle material. After coarse crushing, although the particle size of most of the materials is still relatively large, the particle size of a small part of the material...
