Hazemag know-how on show at Hillhead

A major feature of the HAZEMAG stand at Hillhead 2012 will be a fully operational model of the HAZEMAG VARIOwobbler^â. This new generation of roller screen, designed for pre-screening operations in crushing plants, offers the facility to vary the gap between individual shafts by means of an hydro-mechanical control system. It means that the the granular size of screened product can be determined at the touch of a button, allowing the operator to achieve a consistent quality of screened feed to the crusher, despite any changes in the characteristics and properties of the initial feed material.

Also displayed will be an AP-KVH 1005 R sand impactor designed to produce high quality, uniformly-sized sand and chippings at capacities up to 60tph.The impactor features generously-sized doors for full access to internals and blow bars are inserted laterally, to permit quick and easy turning or replacement. Impact aprons are hydraulically adjustable and the AP-KV's housing is lined with easy-to-change wear plates. It has a reversible rotor, which allows rotation direction to be changed to ensure that blow bar striking edges are fully utilised, and rotors can be supplied with either two or four blow bars.

A vibrating feed system and vertical inlet arrangement provide optimum feed distribution over the whole length of the rotor to achieve optimum comminution of feed material whilst maintaining even wear rates of the blow bars.
