Integrated space stone shaping and screening system

Abstract

An integrated space stone shaping screening system solves the problems that existing stone shaping screening equipment is miscellaneous, heavy and large in occupied area. According to the technical scheme, the integrated space stone shaping screening system comprises a preprocessing system, a hoisting system, a preprocessing device, a stone shaping device, a screening device, a secondary sliding screening device and a matched dust removal system. The preprocessing device, the stone shaping device, the screening device and the secondary sliding screening device are sequentially arranged in a mounting rack of confined space in the vertical direction. The screening device comprises at least an upper-layer screening net, a lower-layer screening net and a matched discharging outlet channel, screening holes of the screening nets are rectangular, the rectangular screening holes of the upper-layer screening net and the lower-layer screening net are distributed according to the blanking direction from large to small, and screening holes of various sections of the screening nets on the same layer are distributed according to the material flowing direction from small to large. A shock excitation device is arranged on the screening device, and the screening device is obliquely positioned below the stone shaping device and above a grading classification device composed of the secondary sliding screening device. The integrated space stone shaping screening system has the advantages of being small in occupied area, good in dust removal effect and high in screening efficiency.

Description

technical field [0001] The invention relates to the field of stone shaping and screening, in particular to an integrated space stone shaping and screening system. Background technique [0002] At present, the domestic road construction teams use stones that have not been shaped. The industry lacks standardized management on the size and shape of road materials, especially stone materials. The stone particles are bound together by asphalt. If the stone has sharp points and edges, the strength of the sharp points and edges is weak, which will damage the asphalt mucous membrane on the stone bonding surface and form cracks. Flat flake stones are more likely to break during use. The crushing process also causes gaps at the junction to form dust inclusions, which reduces the strength of the road surface. Because stone processing belongs to the primitive level of labor, poor equipment and lack of standards result in inconsistent product specifications and uneven stone sizes, whi...
