Weathered rock is a phenomenon that rocks are broken, loose and mineral composition changes under the action of solar radiation, atmosphere, water and biology. It is generally divided into unweathered rock, slightly weathered rock, moderately weathered rock, strongly weathered rock, completely weathered rock and residual soil.
For strongly weathered rock, completely weathered rock and residual soil, the hardness of the stone is greatly reduced due to the high degree of weathering. If it is made into machine-made sand, there may be problems such as weak compression resistance, which is lower than the quality of machine-made sand generally made of hard stone, thus affecting the quality of later construction projects. Therefore, such highly weathered materials are not recommended to be used as raw materials for machine-made sand.
For general weathered rock, it can be used as machine-made sand raw material to produce sand with a sand making machine. Its production process and equipment selection are roughly the same as those of bluestone, limestone and other stones. The specific needs to be adjusted according to the hardness grade of the stones.

At present, VSI series sand making machine and 5x series sand making machine are widely used in the industry, and 6x sand making machine with larger capacity upgraded on this basis is also widely used.
In addition, under the severe environmental protection situation, the fully sealed production VU Aggregate Optimization System has also attracted the attention of many customers. The system not only has good environmental protection effect, but also has its own particle optimizer. The quality of the finished manufactured sand is also very good, which can meet the standard of high-quality manufactured sand.
