1.Introduction of VSI crusher

      VSI series impactors are represented in Model A and Model B,among them,Model A with a "Rock on A Anvil" crushing chamber is mainly used for low abrasive rock,Model B with a “Rock on Rock”mainly used for abrasive rock.Mode A and Model B can be converted into each other by replacing crushing chamber.VSI series are featured in high reliability,less maintenance and economic operation cost over competitors,all the benefits are from cascade feeding,deep rotor,full feed flow centralization,inner air flow cycling,heavy duty hearings and oil lubrication systems.

2.Features of VSI crusher

(1) Operation theory:Feed material in the hopper goes in two ways,one flow goes directly down to the rotor,being accelerated,and thrown out on the anvils or rock packing where breaking is taken place;the another overflows down to the crushing chamber through the hopper outlets and collides with the high moving material for breaking.

(2) Patented feed centralizer:Feed centralizer could eliminate feed hitting unevenly the wear parts and rotor which will shorten parts life and cause bearings failure;the another benefit is helpful for dust enclosure because of without air flow entering crushing chamber.

(3) Patented air inner cycling design:It assures there is no air in or out of the crushing chamber,so a dust leaking is avoided.

(4) Deep rotor:Perfect balance,high throughput,less wear parts consumption.

(5) Model A,Model B converts other.

(6) Inspection and maintenance door is convenient for wear parts changing without lifting tools.

(7) Oil lubrication system and motor start control are equipped with completed function prevention.
