Principle Components of the Powerscreen Pegson XH320 Crusher Opening Rubber Curtain Chain Curtain Wear Liners Inlet Chute Inlet Wear Beam Full Blowbar Principles of Operation Impact Crusher Apron Adjustment Spindle Control Cylinder Top Impact Apron Apron Adjustment Spindle Bottom Impact Apron Control Cylinder Rotor Half Blowbar Material enters via crusher opening and slides down the inlet chute where it is struck by the blowbars fixed within the rotor. This initial impact breaks the material which is then accelerated towards the top apron where more reduction takes place on impact. This material then falls back onto the blowbars and the cycle is repeated until the material is small enough to pass between the top apron and blowbar. Further reduction occurs on the bottom apron until the material can again pass through the gap and discharge from the underside of the crusher. Should an un-crushable object enter the chamber, the overload cylinders will relieve and allow the object to pass. The cylinders will then return to the pre-set crushing position. The pre-set gap is adjusted by turning the adjustment spindle whilst the weight of the apron is held on the cylinder (hydraulic assist). The hydraulic cylinders are pre-loaded to minimise apron bounce and wear on the cylinders. This arrangement also greatly reduces the oversize produced and is Patent Pending GB2455203 Main Crusher Specification Feed opening: 1130mm x 800mm (44.5 x 31.5 ) Maximum piece size 450mm 3 (18 inches 3 ) depending on material and blowbar spec Rotor width: 1100mm (43.3 ) Rotor diameter: 1040mm (41 ) Number of aprons: 2 Maximum setting: 180mm (7 ) upper apron; 75mm (3 ) lower apron Minimum setting (CSS) 60mm (2.4 ) upper apron and 20mm (0.75 ) lower apron Number of blowbars: 4 Blowbar removal: Vertically Blowbar configuration: 2 full and 2 half (Optional 4 full) Setting adjustment: Hydraulic assist Overload protection: Hydraulic Rotor speeds: 606-740rpm (33-40 m/s) (108-131 ft/s) Applications: Demolition/Recycling/Quarry Crusher weight: 8500 kg (18,740 lbs) Full Blowbar weight: 220 kg (485 lbs) Side liners: 20mm (0.75 ) thick, abrasive resistant steel Page 3

Hinged side door allows access to apron tips and rotor for gap measurements and inspection. Complete hinged section opens hydraulically to allow blowbar removal and replacement, apron and liner replacement or major maintenance Cast steel and fitted with four reversible and replaceable blowbars Double row self aligning spherical roller bearing fitted each end of rotor Cast steel aprons with replaceable abrasion resistant wear plate on tip of bottom apron Direct through wedge belts with tensioning system on the powerpack Rotor bearings are greased and fitted with inner and outer labyrinth seals Standard Blowbar is martensitic steel. High chrome and Ceramic Blowbars optional This plant is designed for both demolition and quarrying applications. When fitted with Martensitic or Ceramic Blowbars the crusher will tolerate small quantities of steel reinforcing bar in the feed. However, the machine is not designed to accept large pieces of steel or other un-crushable objects, and the feed material should be assessed / inspected for suitability prior to crushing. It is vitally important that large pieces of steel or similar un-crushable objects are not allowed to enter the crushing chamber as severe damage and injury may occur. When high chrome bars are fitted all steel should be removed from the feed material. The machine should only be used on quarry applications or clean materials such as asphalt. Page 4
