Efficient energy-saving concrete aggregate production line and method

Abstract

The invention relates to an efficient energy-saving concrete aggregate production line. A feed inlet of a crusher, a plate type feeding machine, a hammer impact crusher, an elevator and a primary vibrating screen are sequentially connected. A primary coarse material outlet, a primary medium material outlet and a primary fine material outlet are formed in the primary vibrating screen and connected with the crusher, a first stock bin and a secondary vibrating screen respectively. A secondary coarse material outlet, a secondary medium material outlet and a secondary fine material outlet are formed in the secondary vibrating screen and connected with a second stock bin, a third stock bin and a fourth stock bin respectively. According to the efficient energy-saving concrete aggregate production line, the optimized scheme that the efficient crusher is used, the elevator is used for conveying and screening machines are arranged at the tops of the stock bins is adopted, in this way, the procedure is greatly simplified, the number of pieces of equipment is greatly reduced, and the number of dust raising points is also greatly reduced; a distributed control system (DCS) centralized full-automatic control scheme is adopted, and thus the efficient energy-saving concrete aggregate production line has the advantages that the number of required workers is small, the occupied area is small, investment is low, and energy consumption is low.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a high-efficiency energy-saving aggregate production line for concrete and a production method thereof. Background technique [0002] The current situation of the sand and gravel industry is still dominated by non-scale production. Under the new background of promoting the development of a new type of "industry-information-industry" strategy, the sand and gravel industry has intensively introduced a series of policies and guidelines from the country to the local area, mainly reflected in the following aspects: 1. Scale has become the mainstream. Second, greening is the direction. 3. Machine-made gravel is the main force. Fourth, reasonable and legal exploitation is the premise. Fifth, industrialization has become a trend. In this context, the industry has accelerated the closure of small-scale aggregate production lines that are more polluting. [0003] And the existing sm...
