The HZSL Modular Sand Crushing Plant adopts modular design, which combines the sand making, screening, feeding, conveying and dust removal systems with the floor structure, with less floor space, short construction period and fully enclosed design to meet the needs of the city. The requirements for the production of mechanical sand are a set of high-grade dry sand production systems. It is especially suitable for high-grade machine sand production requirements with limited area and high environmental protection requirements. It is the best partner for dry mortar plant and commercial concrete mixing plant .The HZSL series modular sand-making plant produced by the Great Wall Construction Machinery adopts the ZS series single-electric mechanism sand machine independently developed by our company. The feeding granularity can reach 100mm, the throughput can reach up to 500 tons per hour, and the sanding rate can reach 50%. Above, the fineness modulus can be controlled at 2.2-3.0, the gradation distribution is uniform, the stone powder content is controllable, the finished sand grain shape is excellent, it can be compared with natural sand,Can effectively improve the strength and durability of concrete, as well as the pumping performance of concrete.
