What equipment is used for coal gangue sand making

In the public's perception, the raw materials for manufactured sand are typically chemically stable stones such as river pebbles, pebbles, greenstone, and granite, or common construction waste materials like concrete and bricks. Therefore, when first hearing about using coal gangue, a solid waste material, for sand making, many in the sand and gravel industry may wonder: Can coal gangue be used for sand making? Can coal gangue meet the requirements for construction sand? What equipment is used for processing? The following will provide an introduction:

Coal gangue can be used for sand production and can meet the requirements for construction sand. The following equipment can be used:

1. Double-roll sand-making machine

This machine crushes materials by squeezing them between two rollers. The drive system is powered by two electric motors, enabling both crushing and sand production. It simplifies the coal beneficiation process, reduces investment and production costs, and has an hourly output of 5–110 tonnes, with an input particle size of ≤30 mm and an output particle size of 2–10 mm.

2. Small Hammer-Type Sand-Making Machine

The hammer-type sand-making machine can process coal gangue into finished sand in a single step, directly producing premium sand with a particle size of less than 5 mm. It has a production capacity of 5-100 tonnes per hour, high efficiency, and a relatively low cost, making it suitable for newcomers to the industry and small-scale investors.

3. Impact Crusher Sand-Making Machine

This is a relatively new fixed sand-making equipment that combines sand-making and shaping functions. It adopts a deep-chamber rotor, significantly increasing the throughput of coal gangue and improving the equipment's production efficiency. It produces high-quality sand, The finished product is cubic-shaped particles. The machine's lubrication system is interchangeable, providing strong protection for the equipment with a low failure rate. It is equipped with dust removal and dust prevention devices to reduce dust particle pollution emissions and lower noise levels, ensuring that environmental issues related to coal gangue sand-making equipment do not affect production.

4. Mobile Sand-Making Machine

The mobile sand-making machine is a mobile impact crusher, available in two types: tyre-mounted and track-mounted. Mobile sand-making machines feature high output, high efficiency, and low operating costs. No piling installation is required, no raw material transportation is needed, one machine equals one factory, and one person can operate production. This means that for every tonne of manufactured sand produced, significant costs are saved, effectively increasing monthly profits.
