A 50-100 tons per hour (tph) sand production line is a medium-scale, efficient, and flexible aggregate processing system widely used in construction, road building, water conservancy, and other engineering fields. This production line can be modularly configured according to raw material characteristics (such as limestone, granite, basalt, etc.) and finished sand requirements, balancing capacity, particle shape, and environmental protection.
A typical 50-100 tph sand production line usually consists of a feeder, jaw crusher, cone or impact crusher, sand making machine (such as a VSI vertical shaft impact crusher), vibrating screen, sand washing machine, and conveying system. The process generally involves: raw materials are uniformly fed into the jaw crusher for primary crushing via a vibrating feeder, then undergo secondary crushing by a secondary crushing equipment, followed by fine crushing and shaping in the sand making machine to produce manufactured sand that meets national standards. After screening by a vibrating screen, unqualified materials are returned for further crushing, and qualified sand can be processed by dry dust removal or wet sand washing.
This scale of production line offers advantages such as moderate investment, small footprint, high degree of automation, good finished sand particle shape, and reasonable gradation. In particular, the VSI sand making machine, using "stone-on-stone" or "stone-on-iron" technology, effectively increases the cubic content of the sand, meeting the standards for high-strength concrete. Simultaneously, the accompanying dust removal, noise reduction, and wastewater recycling systems enable green production.
Furthermore, the 50-100 tph production line is highly adaptable, capable of both fixed installation and mobile configuration, facilitating easy transfer between multiple construction sites. With the continuous growth of infrastructure demand, this type of medium-sized sand production line is becoming an ideal choice for aggregate enterprises seeking to improve quality and efficiency.
