Sand Maker, Crusher (vertical shaft impact crusher) The vertical shaft impact crusher(sand maker) is the most advanced sandmanufacturer in the world at present. It may be divided into RX series granulator and SX series VSI crusher based on application. RX series granulator is used for rounding the angles of the aggregates to improve the shape of the grain; SX series is used for crushing basalt, granite, pebble, andesite etc. into manufactured sands directly by dry method.This catalogue mainly introduces PEBRAS SX series VSI crusher(sand maker).CINSTRUCTION OF SX SERIES VSI CRUSHER* SX series VSI crusher mainly consists of body, feeding tube, impacting plate, vertical shaft with rotor and motor;* The impact plate is made from special high-Cr cast iron with high wearing property, fastening without bolts, easily replacing;* Equipped with air circling unit to reduce dust discharging;* The rotor fitted with wearing pad to prolong service life, to cut down the quantity of damageable parts ,and to reduce the running cost;* The high speed rotor is balanced to realize lower noise and lower vibration.CRUSHING PRINCIPLE OF SX SERIES VSI CRISHERThe materials to be crushed are fed into the machine from the feed opening at the top, and fall down into the central section of therotor rotating with high speed. Then they are thrown out at great speed by the strong centrifugal force of the rotor, colliding with the impact plates and crushed. The installed impacting plates are collided with the materials to be crushed in a right angle, which gives full play of excellent crushing performance.The manufactured sands with proper size are discharged from the bottom of the machine.CONSTRUCTION CHARACTERISTIC OF SX SERIES VSI CRUSHER* Excellent crushing performance;* Lower running cost: ** Less damageable parts ** Long service life of damageable parts(made from special high-Cr cast iron or hard alloy) ** Impact plate may be adjusted and up-side-down remounted, thus, leading higher productivity ** Easily replacing of damageable parts* Environment friendly ** Lower noise and lower vibration ** Less dust discharging outCAPACITY AND USE ILLUSTRATION* CAPACITY(TABLE 1)TYPE MAX.

The actual production capacity mainly depends on the materials used, and the surface humidity of the materials.In view of the output and service life of the damageable parts, it is suggested that the max. feeding size is had better less than 15mm(width size) .
