Coal gangue can make sand, and from the raw material situation, performance characteristics, sand making process and application areas, etc., can reflect that coal gangue sand making is feasible, the main components are Al2O3, SiO2, and other trace rare elements (gallium, vanadium, titanium, cobalt), the price itself is low, compared with other mining masterbatch cost-effective, low investment costs and high returns.

How about coal gangue sand? Can gangue sand be up to standard? Its particle size is uniform, cubic, low needle flake content, good quality, according to the national technical standards for construction sand, the particle gradation (fineness modulus), clay content, stone powder content (including methylene blue test), crushing index, etc., is able to meet the standards.

Application fields of coal gangue sand making

1、Gangue is easy to mine, after crushing and sand making, the aggregate has better adhesion and compressibility, and the fineness modulus can be controlled artificially through the production process, and the production can be organized according to the user's requirements.

2, gangue sand production in the use of cement and other structural bonding, good adhesion, compressive resistance, corrosion resistance, no radiation, long service life.

3、The composition is not as complicated as natural river sand, its chemical composition and mineral composition is basically the same as the raw material of mechanism sand.
