Environment-friendly high-quality sand making building station system

Abstract

The invention discloses an environment-friendly high-quality sand making building station system. A discharging port of a feeding and collecting bin is connected with a feeding port of a spill waterfall type vertical shaft through a pipeline, a discharging port of the spill waterfall type vertical shaft is connected with a feeding port of a primary powder concentrator, and a plate conveyor is placed below a discharging port of the primary powder concentrator. The system has the benefits as follows: 1, the gradation and fineness can be controlled according to demands of clients, so that different selling prices of products in different specifications can be obtained, and better economic effects can be obtained; 2, the capacity is high, finished products have superior granule shapes and thesand production rate is high; 3, the stone powder content and moisture content of sand can be controlled as required.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an environment-friendly high-quality sand making building station system. Background technique [0002] With the continuous development of my country's economy, various large-scale construction projects are gradually increasing, especially the rapid development of high-speed rail, the continuous emergence of super high-rise buildings and long-span bridges, the performance requirements of concrete are getting higher and higher; and sand and gravel as concrete The raw material with the highest proportion, its performance directly affects the performance of high performance concrete. In the existing major projects, almost all important structures require high-performance concrete, and the sand of high-performance concrete must use natural sand to ensure its performance. As a non-renewable resource, natural sand is already facing depletion. The mining of natural sand ha...

AI Technical Summary

Problems solved by technology

[0006] 1. The air screen is used for screening, although the vibration is small and the energy consumption is low; but the screening accuracy is low, the efficiency is low, and the production capacity is low, which cannot meet the needs of high production capacity and high efficiency;

[0007] 2. The equipment configuration is single, only simple sand making or shaping; when there is only a sand making machine, the sand production rate is high, but the grain shape is poor, and the quality of the finished product is poor; when there is only a shaping machine, the finished sand grain shape is good, but the sand production rate is low. Too many returns, low crushing efficiency and low production capacity

[0008] 3. There is no special coarse and fine sand adjustment channel, and it is difficult to control the thickness ratio of finished sand by air sieve wind force, and it is difficult to guarantee the gradation and fineness modulus of sand;

[0009] 4. Some have a variety of equipment configurations for sand making. Although the sand making effect is good, the process is too complicated, there are many equipments, and the layout is cumbersome. Not only does the cost of the equipment increase, but also the structure of the entire building is huge, and the height is greatly increased. The net height of the building Even more than 20 meters, greatly reducing the stability and safety of the building;

[0011] 6. The performance of the powder selection equipment is poor, and the dust control is not ideal
