A concentrate dehydration process and device

Abstract

The invention provides a concentrate dehydrating technology and a device, which is composed of a set of dehydrating pools (3) with special devices (3) and a high pressure air supply system (1) which are manually matched, a dehydration task comprising three processes: settling dehydration, vibration dehydration and pneumatic dehydration, is completed by utilizing self characteristics of concentrate slurry. The concentrate slurry, after natural settling dehydration in the dehydrating pool (3), is blown into a bottom surface of the dehydrating pool (3) by a high pressure blast to generate a big blasting force and a big vibration force, to make solid particles be dehydrated from a hydration membrane package and generate settlement and compaction, and water is extruded out and blown into a water return system (4) by high pressure blast, thereby making a water content of a concentrate product reach a standard requirement. The concentrate product is loaded, transported and sold by a concentrate loading and transporting system (5). The technology and device has advantages of simple flow, small equipment, no intermediate material conveying and transferring link, no filtering medium, energy saving, consumption reduction and low labor intensity, is suitable for dehydration of the concentrate of various metal and nonmetal ores, and is suitable for large scale industrialization production.

Description

technical field [0001] The invention relates to a concentrate dehydration process and device in the mineral processing process, especially a process and device capable of removing the water wrapped in a hydration film in a fine-grained concentrate. The process and device are suitable for various metal and non-metallic minerals. Concentrate dehydration is suitable for large-scale industrial production. Background technique [0002] At present, the known mineral processing process concentrate dehydration process is mainly composed of three parts: concentration, filtration and filtrate treatment. Most of the concentration and filtration parts are completed by special equipment. Technical parameters such as blowing pressure and blowing pressure have strict requirements, so the process flow is complex, operation control is difficult, the water content of the concentrate product is difficult to meet the standard, and the energy consumption is large and the production cost is high....

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiency that the existing concentrate dehydration process equipment and devices cannot effectively remove the hydration film wrapped water in the fine-grained concentrate, the present invention provides a concentrate dehydration process and device, the concentrate dehydration process and device not only It can remove the hydration film-wrapped water in the fine-grained concentrate, so that the water content of the concentrate product can meet the standard requirements, and the process is simple, the equipment is less, and it is easy to operate and control, which can save construction investment and reduce production costs.
