Abstract
A process for preparing the calcined kaolinite includes such steps as dressing ore, crushing, pulverizing by 325 meshes, mixing with water and disperser, pulverizing by 4500-6000 meshes, drying, pulverizing, calcining at 970-990 deg.C for 30-40 min while adding whitening agent, and breaking. Its features high whiteness and fineness.
Description
Technical field:
A kind of kaolin calcined producing process belongs to the nonmetallic minerals manufacture field.
Background technology:
Traditional calcining kaolinite (soil) be the kaolinite ore through ore dressing, pulverizing, ore grinding, be processed into 200～800 purpose powders; Or raw ore is through ore dressing, washing, drying; Advance calcining furnace (kiln) calcining.With the kaolin of produced in conventional processes, the whiteness of its product has only 80～90, and the quality instability.Product can only be used in pottery, building materials and the low and middle-grade coating.Some Link Efficiency in the traditional technology are also lower in addition, as: dehydrate operation.
Summary of the invention:
The objective of the invention is to improve the whiteness of kaolin product, improve the low problem of part Link Efficiency in the traditional technology simultaneously.
Kaolin calcined producing process of the present invention is that ore dressing is the fragment of 45 to 55 millimeters of diameters with ore reduction, wears into the following powder of 325 orders then; Powder is sent into the slurry bucket, and after adding the water of equivalent weight, add the dispersion agent stirring to pulp of gross weight 3-5% again, the concentration of slurries is carried out superfine grinding to the 4500-6000 order at 45-55% with the mud pumping machine of delaminating; Powder after superfine grinding slurry is carried out drying break up, send into calcining furnace and calcine, add the improver of gross weight 1-3% during calcining, calcining temperature 970-990 ℃, the time is 30-40 minute; Break up and be packaged as finished product.Improver is made up of cleaned coal, sodium sulfate and sodium-chlor, is ground into the 4000-5000 order, mixes at 10: 0.3: 0.2 by weight.The dispersion agent that uses in the above-mentioned technology is inclined to one side microcosmic salt acid or amides superpolymer.Break up in the operation in drying, the nozzle bore of shower nozzle is become the adjustable angle of 15-25 degree with vertical direction, and allow shower nozzle rotate with 60-200 rev/min speed, the ultra tiny atomization particle of formation and tangential direction enter the hot blast countercurrent flow in the spray tower, strengthening heat transfer improves exsiccant efficient.
The kaolin product that utilizes this Technology to calcine out, the detection means of pressing standard-required makes product whiteness reach 90～95, and granularity reaches 4500～6000 orders, has guaranteed that the every performance index of calcined kaolin of being produced reach processing requirement.
The Gao Bai, the superfine calcined kaolin product that use this production technique to produce are mainly used in industrial circles such as papermaking, high-grade paint.
Embodiment
Raw ore is put into former feed bin with shovel loader in the raw ore storehouse, send Roughpulverizer through rotary conveyor, pulverizes the fragment into the 50mm granularity.Raw ore after the fragmentation falls into conveyor and send the Raymond machine abrasive dust, and powder falls into conveyor through blower fan and fly-ash separator collection.Establish electric magnetic iron remover and electronic weighing balance on the conveyor and carry out deironing miscellaneous material and metering.Raw ore becomes the following powder of 325 orders behind the abrasive dust.Behind the powder feeding warehouse, advance the slurry bucket through conveyor.The slurry bucket adds the water with the powder equivalent weight, and adds the dispersion agent (metaphosphate) of powder and water gross weight 4%, stirring to pulp, and concentration of slurry carries out superfine grinding with the mud pumping machine of delaminating then 45～55%.Slurry is under the effect of the grinding medium and the agent of dissociating, and the segmentation fine grinding becomes 4500～6000 purpose slurries in the machine high speed rotating of delaminating, and is standby with mud pumping stock tank.Mud is sent into comprehensive calcination plant again with pump, and spray-dried machine drying makes its water content less than 3%, when dry, the nozzle bore of shower nozzle is become the adjustable angle of 20 degree with vertical direction, and allows shower nozzle rotate with 150 rev/mins speed.Powder through transfer roller enter feed bin through beater break up, classification, be conveyed into calcining furnace with wind-force before feed bin standby.Cleaned coal, sodium sulfate and sodium-chlor separated pulverizing are become the 4000-5000 order, and it is standby to be mixed and made into improver by weight at 10: 0.3: 0.2.The whitening agent of kaolin powder and weight 2% thereof is added the calcining furnace calcining in the lump, and calcining temperature 970-990 ℃, the time is 30-40 minute.After the powder classification of calcining back, enter the finished goods inventory as ready through wrapping machine metering, packing.
Claims (2)
