XH250 SPECIFICATION - OVERVIEW

The TEREX Pegson XH250 Horizontal Shaft Impactor is a highly compact tracked crusher designed to reinforce a world class range of tracked machines. The TEREX Pegson XH250 offers both excellent reduction and high consistency of product yield. The XH250 is designed mainly for the recycling and demolition markets and is an ideal contract machine due to the compact design and mobility.

Principles of Operation

Material enters via the crusher opening and slides down the inlet chute where it is struck by the blowbar which is held within the rotor. This initial impact breaks the material which is then accelerated onto the top apron where more reduction takes place on impact. This material then falls back into the blowbars and the cycle repeated until the material is small enough to pass between the apron and the blowbar. Once through this gap, further reduction occurs on the bottom apron until the material can again pass through the gap and discharge from the underside of the crusher. Any uncrushable material entering the chamber will relieve the overload cylinders and allow the material 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).

XH250 SPECIFICATION - IMPACT CRUSHER

Main Features Crusher Body: Fabricated from steel plate and fully lined with replaceable abrasion resistant liner plates. 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 Rotor: Cast steel and fitted with four reversible and replaceable blowbars Bearings: Double row self aligning spherical roller bearing fitted each end of rotor Aprons: Cast steel aprons with replaceable abrasion resistant wear plate on tip of bottom apron Drive: Direct through wedge belts with tensioning system on the powerpack Lubrication: Rotor bearings are greased and fitted with inner and outer labyrinth seals Blowbars: Standard blowbar is martensitic steel. Options are available in high chrome and ceramic Applications This plant is designed for both demolition and quarrying applications. When fitted with martensitic or ceramic blow bars 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 uncrushable 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 uncrushable 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 and the machine should only be used on quarry applications, or clean materials such as asphalt.
