Abstract
Description
Technical Field
[0001] The utility model relates to a highly efficient and energy-saving system for dehydrating fine powder used for flake graphite ore dressing and subsequent production. Background Art
[0002] After multiple stages of flotation, the carbon content of graphite reaches 94%, which becomes the final concentrate product. The concentrate foam slurry needs to be dehydrated and dried, as well as screened before delivery. Existing dehydration and drying generally use plate and frame filter presses, earthen beds, drying kilns or rotary drum dryers. The moisture content of the material after dehydration by the plate and frame filter press is relatively high, generally around 30%, which puts a lot of pressure on subsequent drying. High-temperature drying has low energy utilization and high calorific value loss, which is not conducive to enterprises reducing production costs and needs to be improved. Enterprises generally temporarily store the dried materials and screen them before delivery. Stacked damp and agglomerated materials are prone to block the sieve holes, which brings certain troubles to continuous and smooth production; and the traditional drying equipment workshop is dusty, affecting the health of workshop workers.
