Point, if the equipment work site is a high temperature environment, then the mill can be placed in a ventilated position, this can ensure that the motor work heat dissipation, which is an effective program to extend the service life of the motor.

Artificial sand production, can be divided into mechanisms of sand and broken marble grinder mechanism sand two categories. Rod mill mechanism sand with process stability, maturity characteristics. Crushing mechanism has vertical impact crusher sand sand and other types of rotating disk fragmentation laminated form , but the application of more PCL vertical shaft impact crusher.

Smaller than the marble grinder volume , basic simplicity , high efficiency, but the vertical impact crusher mechanism is not completely sand sand requires closed- loop circulation process large amount of finished sand fineness modulus compared large, coarse particles , and the particle size distribution is not ideal , especially in the production of limestone sand, grit and powder have produced more intermediate level of particles less than normal shortcomings.

This requires supplemented easy to control , stable quality marble grinder as a regulation. This can complement each other, that the impact of the joint use of vertical sand breaking technology combining with the marble grinder . In fact , finished by a vertical impact crusher sand is sand , sand and some mechanism marble grinder less than 5mm screen blanking, and most blended powder 4 made ​​, the composition of the particles of sand products more reasonable.

Duck Creek Pengshui hydropower male sand aggregate processing system uses three V1400 vertical impact with four broken marble grinder joint sand , finished sand production capacity of up to 370t / h.
