Our manufactured sand-making crusher is to apply impacting, grinding, rubbing and other high-efficiency and reasonable ways to crush stone materials. Qualified sand particles are exhausted out of the crusher in time and become products, and unqualified particles are sent forward for further crushing till being exhausted out as qualified products. Core technology of PL Air Classifier is to separate particles by air only without sieving equipment, but the separation precision and efficiency are high with no abrasion, noise and dust pollution.And here is a list of advantages of using our products:
①　High Return: saving 10%-30% cement
②　Saving energy and wear parts consumption: Significant energy saving 50% compared with conventional equipment .The consumption of wear parts is RMB 0.5~1 Yuan/t.
③　High Performance:Stable and safe operation, rarely need to repair.All the solutions are proven and reliable multiply.  
④　Saving energy and wear parts consumption: Significant energy saving 50% compared with conventional equipment .The consumption of wear parts is RMB 0.5~1 Yuan/t
⑤　Superior cubical shape and standard particle size distribution
⑥　Eco-Friendly: Negative pressure operation is without dust.Noise lower than 80dB.
