PCL Sand Making Machine PCL sand-making machine has high performances but low consumption with international advanced level. It is irreplaceable for mining fine crushing and is an effective, practical and reliable sand-making machine currently.It is widely used in crushing of metal and nonmetal or cement, refractory material, bauxite, quartz, glass raw material, building aggregate, artificial sandy soil and all sorts of metallurgy slag, especially for middle hardness and special hardness material. PCL Sand Making Machine Features: 1.High hardness material crushing. 2.Safety and environmental protectionand durable. 3.Strong adaptability. 4.Simple structure, versatility. 5.Low working noise. Working Principle : Stone less than 60mm enters sand making machine though conveyor belt. Stone is crushed by hitting other stones. Material falls down to impellor cavity. Under great centrifugal force, it hits material that coming downwards. After hitting each other, they force a vortex between impellor and shell, and hit each other several times, finally smaller stone comes out, and goes to vibrating screen. Satisfactory material is transported to sand washing machine, however overlarge material will go back to sand maker to be recrushed. Output sizes can be made according to customers requirement. If input size is larger than the designed size, other crushing equipment will be necessary.
