High-quality basalt machine-made sandstone aggregate production line and technological process thereof

Abstract

The invention belongs to the field of manufacturing of machine-made sandstone equipment, and provides a dry-wet combined intelligent environment-friendly high-quality basalt machine-made sandstone aggregate production line. A technological process is designed into three-section crushing, wet method and dry method combined production, wherein coarse crushing is carried out by a hydraulic gyratory crusher in an open circuit manner; the intermediate crushing is formed into closed-loop production through a cone crusher and graded screening; and fine crushing is formed into dry-method closed-loop production through vertical shaft sand crushing and checking and screening, and is also supplemented with open-loop production of a rod mill. According to the dry-wet combined intelligent environment-friendly high-quality basalt machine-made sandstone aggregate production line, by comprehensively utilizing technical means such as a computer network, wireless communication, space positioning and geographic information, controllability of the whole production process of the sandstone aggregate is achieved. By adopting the dry-wet combined intelligent environment-friendly high-quality basalt machine-made sandstone aggregate production line, firstly, the high quality of the aggregate can be ensured; secondly, green and environment-friendly production is realized; and thirdly, intellectualization and controllability of process control can be realized.

Description

technical field [0001] The present invention relates to a machine-made sandstone aggregate production line, furthermore, it relates to a high-quality basalt machine-made sandstone aggregate production line, more specifically, it relates to a dry-wet combination intelligent environment-friendly high-quality basalt machine-made sandstone aggregate production line. Background technique [0002] In my country's traditional machine-made sand and gravel aggregate production scheme, there are dry sand making, wet sand making and dry-wet combined sand making. Disadvantages: Some production lines have unreasonable equipment configuration and process design according to different raw stone materials, resulting in low product quality. Firstly, the aggregate particle shape is not round enough, and the needle and flake content> 15%, resulting in aggregate coagulation and The heterogeneity is poor; secondly, the aggregate gradation is unreasonable, the fineness modulus and stone powder ...

[0002] In my country's traditional machine-made sand and gravel aggregate production scheme, there are dry sand making, wet sand making and dry-wet combined sand making. Disadvantages: Some production lines have unreasonable equipment configuration and process design according to different raw stone materials, resulting in low product quality. Firstly, the aggregate particle shape is not round enough, and the needle and flake content> 15%, resulting in aggregate coagulation and Poor heterogeneity; secondly, the aggregate gradation is unreasonable, the fineness modulus, the stone powder content are not up to the standard, and the moisture content is uncontrollable, which cannot meet the different needs of normal concrete and roller compacted concrete.

Some production lines do not meet environmental protection standards. Although dry sand making can solve the problem of high stone powder content in aggregates, a large amount of dust generated during the production process is quite serious for environmental pollution; wet sand making has a large loss of stone powder and is difficult to recycle. Low, unreasonable product gradation, unqualified quality, and it is difficult to realize the recycling of water resources, and the waste water produced will pollute the environment; The disadvantages of wet sand making, and the two cannot be integrated, the system is complex but the effect is counterproductive

Some production lines do not pay attention to automatic production, resulting in uncontrollable product output, unbalanced production, high energy consumption and low efficiency
