SANDVIK UH320 Specification Summary Sandvik UH320 General information 08-02 • UH320 Classic type; is superior in its function and can produce 3 calibrated fractions. The Unit can also be used as a screen Unit, producing up to 4 products • Well known Sandvik CH430 crushing plant with a wide range of mantels and settings for different applications are available. • ASRi is optional. • Beneath the dosage and the screen the chute have 3 flaps which make it possible to divide the feedmaterials so that 33%, 66% or 100% can ether be transported to the crusher or to the screen by seperate conveyors supplier. This make it possible to optimize the quality, and capacity with different raw materials. • Remote-controlled tiltable static bar grizzly on feed hopper. Adjustable fixed position between 7-17°. The grizzly is divided in three sections, which can easily be taken off when the feeder is loaded from a conveyor and also changed according to individual wear. The whole grizzly can be removed if not required. Grizzly separation is accordingly to the crusher chamber 100mm alt. 125mm. • Foldable flaps on feed hopper can give wider loading area. • IR level monitors on feed hopper to regulate the feed rate. • A foldable flap on each side can be used as a back-wall for a loader ramp and as protection against oversize stones falling from the tip able grizzly. • The Screen is a SF1843 which can take out 3 calibrated fractions • Rollaway discharge chute on screen provides easy access for inspection and service. • Flaps inside the chute provide adding top fractions with fine fractions except for the oversize conveyor • All conveyors are electrically driven and hydraulically foldable for transport, except for the oversize return conveyor. • Oversize conveyor is equipped with stone brake and side protection plates intended only for screening natural gravel (to prevent rolling stones causing damage and accidents). Removed during transport. • Dust-encapsulated feed conveyor, screen and conveyor for the finest fraction. • Hydraulic supporting legs at front end make connection with semi-trailer easier. • The whole unit can be transported in one piece if local transport legislation permits, start-up time approx. 30 minutes. • Walkways (with industrial stepladders) around the screen, to provide easy access for inspection and service. • Self-contained galvanised steel switchgear cabinet fixed on-board the unit. The cabinet contains all the components necessary for power distribution specifications and control - fuses, contactors, indicating lamps, control push buttons, interlocking relays, etc. • Emergency stop push buttons are placed at strategic locations. • Frequency convertor for feeder and conveyor for coarsest product, to provide step less regulation of feed rate and conveyor speed. • 220V transformer for power outlet ( 2pc.10A, 1pc.16A). • 32-pole connection for external control of the Unit. • The Unit has no on-board genset due to the axle load limits. • The design and manufacture of UH320 complies with ISO 9001
