Symmetric integrated crushing system

Abstract

The invention discloses a symmetric integrated crushing system, mainly comprising a vertical hoister, a horizontal crusher, a center body, a negative pressure powder removing device and a grading and vibrating screen, wherein the vertical hoister, the horizontal crusher, the center body, the negative pressure powder removing device and the grading and vibrating screen are arranged on a same frame and form a stereoscopic structure. Two lateral discharge holes are respectively connected with a left feed inlet and a right feed inlet of the center body, so material crashing and crushing zones are further formed in the center body, and the area of a bottom outlet of the center body matches with the area of a screen surface of the grading and vibrating screen. The crushing system is of a totally-enclosed structure. The symmetric integrated crushing system provided by the invention has the advantages of a compact designed structure, easy and convenient installation, good adaptability, good sealing performance, uniform granularity of a discharged material, great production capacity, a high crushing ratio, environment friendliness, conservation of energy and capacity of saving more than 30% of energy.

Description

Technical field: [0001] The invention relates to a material crushing system, in particular to a dry sand making crushing system, in particular to a symmetrical integrated crushing system. Background technique [0002] Sand making equipment belongs to material fine crushing equipment. The crushing of materials in the crusher generally has various forms such as extrusion, splitting, shearing and impact crushing. The crushing principle of most crushers is the joint action of several forms. Commonly used machine-made sand equipment has the following types, cone crusher, rod mill, double-roll crusher, impact crusher and impact crusher. From the initial rod mill adopting the principle of crushing and grinding, it has developed to the principle of lamination crushing of the rotary sand making machine and the principle of material mutual grinding and impact shock cracking of the "stone-on-rock" impact crusher. [0003] Since the production of wet sand requires a large amount of ...

AI Technical Summary

Problems solved by technology

[0005] At present, the dry sand making process generally adopts an open series connection method, and multiple belt conveyors are used to connect single-function sand making equipment in series according to the process requirements. The entire production line occupies a large area, high energy consumption, and low efficiency. The dust pollution of traditional production is serious, and it is difficult to achieve the requirements of fully enclosed environmental protection
