CONTINUOUS DRYING, DISAGGREGATING AND CENTRIFUGING SYSTEM FOR METAL AND NON-METAL MINERAL CONCENTRATE

摘要

The invention relates to a continuous drying, disaggregating and centrifuging system for mineral concentrates that is automated, modular, of a mechanical type that makes it possible to reduce the moisture % of the mineral concentrate to an acceptable moisture in order to improve the yield and the quality of the mineral concentrate, comprising two units: A) a support, control and power unit that includes: a) a movable rectangular steel platform, with a length of 12,000 mm, capable of supporting 25 tonnes, collapsible steel-tube handrails being placed around the entire platform, and the side walls of the platform comprising collapsible ladders; and two digital control and power panels (13), attached to the front wall (6a), including an acoustic siren (31) for initial safety, and at 1000 mm is located b) a unit c) a compressor with an air pressure of 120 psi, d) a water tank with a capacity of 1000 l, connected to a 1 HP pressure pump and arranged in one of the side walls; B) a unit for drying, disaggregating and centrifuging material, which comprises: e) a hopper for feeding the mineral to be dried, supported by a mechanical structure, and unloading to f) a feeding belt which is self-supported and held by a mechanical structure, that includes protective skirts, this belt feeds g) a drum with a diameter of 1000 mm and a length of 4000 mm, protected around its circumference by a metal cover having four inspection hatches; inside the drum are arranged nine blades with a diagonal configuration for moving the material and twelve blades with a concave configuration for disaggregating and stirring the material; unloading chutes are arranged at the bottom of the drum for receiving the disaggregated and dried material, and conveyor belts are installed under each chute; and C) software developed specifically to remotely monitor, operate and control the drying and disaggregating system.
