Gangue can be used for machine-made sand production, which meets the construction standards. Its sand making process has fixed and mobile types, with the advantages of high efficiency and flexibility. The policy supports recycling, and high-performance equipment ensures quality. Gangue sand making is environmentally friendly and has economic and social benefits.

With the increasing demand for machine-made sand in the sand and gravel industry, gangue, a mineral material with abundant resources and easy access, has gradually attracted people's attention. So, can gangue be used for machine-made sand production? Does the sand and gravel aggregate made from it meet the standards for construction sand? This article will answer these questions step by step.

Gangue crushing and sand making equipment

Can gangue be used for machine-made sand?

The chemical composition of gangue is basically the same as that of machine-made sand raw materials, and the fineness modulus is controllable. It can produce coarse sand, medium sand or fine sand that meets the needs of construction, meeting the needs of construction, roads, infrastructure and other projects. The machine-made sand made from gangue has good adhesion and compressive strength, and has a long service life, so it is widely used in concrete mixing, road construction and other fields.

Gangue sand making process

Gangue is not hard and has low processing difficulty. The following two solutions can be used:

Fixed gangue sand making process

Process flow: feeder-jaw crusher-impact crusher-sand making machine-sand washing machine.

Advantages: high production efficiency and good particle shape, suitable for application fields with high requirements for finished product quality, such as high-standard construction sand.

Mobile gangue sand making process

The mobile sand making process is equipped with tire-type or crawler-type mobile equipment, without site restrictions, high flexibility, and suitable for construction sites that need to be relocated quickly.

Advantages: flexible production, saving transportation costs, and high degree of intelligence.

Feasibility analysis of gangue sand making

Material advantages

Gangue is easy to crush, and the sand and gravel aggregates made are uniform in particle size, strong in compressive resistance, and reasonable in grading. Its finished products can be used in recycled bricks, road construction and other fields, and have good application prospects.

Policy support

The state encourages the recycling of industrial waste such as coal gangue to reduce pollution and improve resource utilization efficiency. The process of making machine-made sand from coal gangue not only complies with environmental protection policies, but also obtains additional support through tax incentives, and has obvious economic and social benefits.

How to ensure that the machine-made sand made from coal gangue meets construction standards?

The quality of sand made from coal gangue is closely related to the selection of sand making equipment. Choosing high-performance sand making equipment (such as VSI5X sand making machine, VSI sand making machine) can not only improve product quality, but also extend the service life of the equipment. These equipment have good crushing effect, high wear resistance, and strong production capacity, which can ensure that the quality of machine-made sand made from coal gangue meets the standards for construction sand.

As a machine-made sand raw material with great potential, coal gangue meets the needs of environmental protection and resource utilization. Choosing appropriate equipment and process flow can ensure that the machine-made sand made from coal gangue meets the requirements of construction sand.
