Double roller machine for artificial sand making
Generally, all processed machine-made sand and mixed sand are collectively referred to as artificial sand, which is divided into rock particles with a particle size of less than 4.75mm by machinery and sand making. In addition, river sand mining is prohibited in recent years, and various infrastructure constructions continue to develop. The amount of sand used has also greatly increased, becoming the main raw material
Is it possible to use a roller machine for artificial sand?
Yes, because it is a device that uses two oppositely rotating rollers to crush materials. It can produce stones and sand. It is suitable for medium and high hardness materials. The compressive strength is ≤160MPa, such as river pebbles. , Pebbles, limestone, coke, coal mines, etc. In addition, using this machine to crush raw coal, it can be crushed directly after iron removal, impurity removal, and no gangue removal. The finished product has uniform particle size and low over-crushing rate, which simplifies coal preparation. The technology reduces investment and production costs.
How about the roller machine sand?
The finished product rate is 85-90%, with good grain shape, low needle and flake content, no internal cracks, fine particle size, and at the same time the particle gradation, mud content, stone powder content, crushing index, apparent density, bulk density, etc. are in line with the technology index.
