Sand producing equipment and process suitable for materials of various specifications

Abstract

The invention discloses sand producing equipment and process for materials of various specifications. The sand producing equipment comprises a raw material conveyor line, a raw material crusher, a semi-finished product conveyor line, a semi-finished product screening machine, a powder removal system and a finished product output line, wherein a conveying start end of the raw material conveyor lineis provided with a raw material bin; the raw material crusher comprises a raw material inlet which is jointed with a conveying tail end of the raw material conveyor line, and a semi-finished productoutlet for discharging a crushed semi-finished product; a conveying start end of the semi-finished product conveyor line is jointed with the semi-finished product outlet; the semi-finished product screening machine comprises a screening inlet jointed with the conveying tail end of the semi-finished product conveyor line, and a screening outlet for discharging screened semi-finished products according to the specifications; the powder removal system comprises a plurality of dust removal lines which separately correspond to the raw material conveyor line, the raw material crusher, the semi-finished product conveyor line and the semi-finished product screening machine; the screening outlet comprises a finished product outlet and a returned crushed material outlet; a conveying start end of thefinished product output line is jointed with a finished product outlet; and the returned crushed material outlet is jointed with a raw material inlet of the raw material crusher. The sand producing equipment of the structure can be suitable for producing materials of various specifications, and can achieve relatively high production standards.

Description

technical field [0001] The invention relates to the field of sand-making system equipment and a sand-making process. Background technique [0002] The traditional sand making process usually transports the aggregate to the crusher for crushing and processing into semi-finished products, and then transports the crushed semi-finished products to the screening machine for screening, and the screened products of different sizes are output separately, which meets the requirements of sand making. The finished products of the size are output, and the ones that do not meet the size are sent back to the crusher for further crushing, and then the sand and gravel of the required size are produced in the output. [0003] The size uniformity of the sand produced by the existing aggregate sand making system equipment is low, and the dust content in it is relatively high. If it is used for asphalt mixing, it is relatively rough. The sand making process is directly related, for example, th...

Problems solved by technology

[0003] The size uniformity of the sand produced by the existing aggregate sand making system equipment is low, and the dust content in it is relatively high. If it is used for asphalt mixing, it is relatively rough. The sand making process is directly related, for example, there is no dust removal when the aggregate is conveyed, the dust removal effect is poor, the working effect of the mechanical equipment is poor, and the production compliance rate gradually decreases with the increase of the use time, so the solution to the above problems needs to be solved from the production equipment of the sand making system and sand making process, and make improvements to sand making equipment and sand making process

[0004] In addition, the existing aggregate sand making system equipment has unstable working efficiency, cannot efficiently and rationally utilize production energy, and has the problem of wasting production energy
