VSI Impact Sand Making Machine: High-efficiency Sand Making and Particle Optimization Specialist

VSI impact sand making machine has become the core equipment for fine sand making in mining industry by virtue of the double mode crushing principle of “stone hitting stone” and “stone hitting iron”. Its advantages are reflected in:  

1. High-grade sand: through high-speed collision crushing of projectile materials, the output is rounded and well-graded sand, with controllable powder content to meet the national standard for concrete sand;  

2. Flexible adaptation: hydraulically adjust the rotor speed and feed volume to adapt to different raw materials such as granite, pebbles, tailings, etc., with a single machine capacity of 50-650 tons per hour;  

3. low consumption and environmental protection: reduce energy consumption by 40% compared with traditional sand making equipment, closed structure combined with pulse dust removal, dust emission ≤ 20mg/m³.  

In application, VSI equipment is mainly used for aggregate shaping (such as crushing 5-10mm gravel to 0-5mm high value-added sand), construction waste recycling sand (concrete block crushing and resource utilization) and other scenarios. For example, in a granite production line, VSI further processes the coarse crushed products of jaw crusher and cone crusher, and the proportion of mechanism sand is increased to 35%, replacing natural sand for commercial concrete mixing, and the return rate of the project is increased by 20%.  

With the tightening of infrastructure and environmental protection policies, VSI sand making machine with “high efficiency, green, intelligent” characteristics, has become the key equipment for the mining crushing industry to improve quality and efficiency.
