Problems solved by technology

[0002] In China's traditional machine-made sand and gravel aggregate production line, there are many problems regardless of dry sand making or wet sand making: some production lines are unreasonable in equipment configuration or process design according to different raw stone materials, resulting in low product quality, manifested as Firstly, the grain shape of the aggregate is not round enough, and the content of needles and flakes is more than 15%, which leads to poor coagulation and heterogeneity of the aggregate; secondly, the grading of the aggregate is unreasonable, the fineness modulus, the content of stone powder are not up to the standard, and the moisture content is uncontrollable , not only cannot meet the sand requirements of commercial concrete, but also cannot meet the requirements of sand for ready-mixed mortar with higher standards; some production lines do not meet the environmental protection standards. A large amount of dust generated is very serious to the environment. Wet sand making, the output of finished sand is low, and a large volume silo needs to be set up for dehydration. The dehydration cycle is long, the loss of stone powder is large, and recycling is difficult. The content of stone powder in the finished sand is low and the gradation is not good. Reasonable, and the production wastewater pollutes the environment heavily, the cost of water treatment is high, and it is difficult to realize resource recycling; some production lines have rough and backward production technology, low degree of automation, let alone intelligence, resulting in uncontrollable product output and unbalanced production. High energy consumption and low efficiency

Embodiment Construction

[0057] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0058] figure 1Among them, the discharge port of the raw stone silo (1) is connected with the feed end of the bar vibrating feeder (2). The discharge chute of the bar-type vibrating feeder (2) is directly connected to the feed port of the jaw crusher (3), and the discharge chute of the under-screen feeder is connected to the feeder through the one-way belt conveyor (4). The feed end of the circular vibrating desilter screen (5) is connected. The discharge chute of the circular vibrating desilting screen (5) is connected to the feeding end of the circular vibration pre-sieve (8) through the connection of the one-way belt conveyor (4), and the discharge chute of the under-screen passes through the one-way belt conveyor (4). The communication of the belt conveyor (4) is connected with the 0-10mm mud pile (6), and the 0-10mm mud is directly loaded into ...

Abstract

The invention belongs to the field of machine-made sandstone equipment manufacturing and provides a high-quality granite machine-made sandstone aggregate production line. The production line adopts acrushing and screening process of jaw crusher coarse crushing, desilting and screening, pre-screening, cone crusher secondary intermediate crushing, vertical shaft impact crusher shaping and coarse aggregate finished product screening at the front end, and adopts a floor type sand making process at the rear end. According to the production line, technical means such as a computer network, wirelesscommunication, spatial positioning and geographic information are comprehensively utilized, monitoring and control information of operation of production line equipment compositions is integrated into a set of intelligent monitoring and control system, dynamic management and control of the sandstone aggregate production line are achieved, and controllability and flexibility of the whole production process are achieved. By adopting the production line, firstly, the high quality of the finished aggregate can be ensured; secondly, green and environment-friendly production process can be realized; and thirdly, the intelligent process control can be realized, and the controllability and the flexibility of the whole production process are ensured.

Description

technical field [0001] The present invention relates to a machine-made sandstone aggregate production line, more specifically, to a fine-quality granite machine-made sandstone aggregate production line, and more specifically, to an intelligent and environment-friendly high-quality granite machine-made sandstone aggregate production line. Background technique [0002] In China's traditional machine-made sand and gravel aggregate production line, there are many problems regardless of dry sand making or wet sand making: some production lines are unreasonable in equipment configuration or process design according to different raw stone materials, resulting in low product quality, manifested as Firstly, the grain shape of the aggregate is not round enough, and the content of needles and flakes is more than 15%, which leads to poor coagulation and heterogeneity of the aggregate; secondly, the grading of the aggregate is unreasonable, the fineness modulus, the content of stone powde...
