CN102909119A - Ultra-fine barite powder processing method - Google Patents

Abstract

The invention discloses a ultra-fine barite powder processing method, which comprises the following steps of: 1, roughly crushing barite raw ore, and then crushing again; 2, washing, finely selecting, dehydrating and drying; 3, grinding to 325-600 meshes; 4, mixing water and barite powder according to a certain proportion to form pulp, adding a drug, and leading the pulp to enter a buffer barrel for stirring; 5, throwing into a main machine to perform wet grinding; 6, throwing a sizing agent in a pulp storage barrel into a secondary vibrating screen by a screw pump; and 7, throwing into a drying barrel for drying, smashing the dried sizing agent by a smashing hammer, classifying by a classification machine according to requirement, leading classified fine powder to enter a bag filtering machine, throwing by a dust catcher and a pulse, leading to enter an automatic package machine, and introducing a packaged product into a product bin. The traditional barite powder method is improved; compared with the prior art, the method has the advantages that the barite powder can be processed into 8,000 to 10,000 meshes and reaches a secondary nanometer level, whiteness is improved by 2 points, and product additional value is improved.

Description

A kind of ultra tiny blanc fixe processing method

Technical field:

The present invention relates to a kind of blanc fixe processing method, especially a kind of ultra tiny blanc fixe processing method.

Background technology

Blanc fixe is a kind of broad-spectrum raw material of industry, can be used for coating, papermaking, the industries such as rubber, plastic cement.Along with the development of industry, increasing to ultra tiny bar demand.And the general inaccessible dimension of blanc fixe of now domestic production, ultra tiny blanc fixe basic need is from external import, and many overseas enterprises sell at high price to China after China's import barite deposit through fine finishining is ultra tiny blanc fixe at a low price.

Summary of the invention

For the deficiencies in the prior art part, the present invention aims to provide a kind of ultra tiny blanc fixe processing method,

Guarantee that the blanc fixe of processing can reach secondary nanophase.

A kind of ultra tiny blanc fixe processing method comprises following operating procedure:

(1), with the former mining jaw crusher coarse crushing of barite, then through the fragmentation of two-stage ring hammer crusher;

(2), the flushing of the input of the barite deposit after fragmentation log washer, be sent to again and jump that the ore deposit machine is selected, dewatered drying, risen in the barite storehouse by bucket elevator again;

(3) by electro-vibrating feeder material is sent in the material grinder and ground, be ground to 325 order to 600 orders;

(4), the 325 orders-600 purpose barite dry powder through grinding hangs in mixing cirtern, with water and blanc fixe furnishing slurry by a certain percentage, adds medicament, enters the buffer barrel stirring by certain solid content;

(5), squeeze into main frame by electric diaphragm pump and carry out wet grinding, in process of lapping, carry out the medicament titration, prevent that slurry is solid, institute's defibrination material flows into vibrations and is sieved to bucket to be checked, the slurry storing tank of being allowed for access after the assay was approved;

(6) slurry in the slurry storing tank being squeezed into the second vibratory sieve by screw pump filters;

(7), then squeeze into the logical heat exchanger that enters of oven dry bucket, carry out drying and processing, after smashing the slurry of oven dry, hammer as requested carries out classification by grader by shattering, fine powder after the classification enters bag filter, enter automatic packaging machine, packed product introduction product warehouse after being laid by deduster and pulse.

This method is improved traditional barite Flour milling method, and compared with prior art, this method can be worked into blanc fixe 8000 order to 10000 orders, reaches secondary nanophase, and whiteness improves 2 points, has improved value-added content of product.

The specific embodiment

Embodiment

(1), with the former mining jaw crusher coarse crushing of barite, then through the fragmentation of two-stage ring hammer crusher;

(2), the flushing of the input of the barite deposit after fragmentation log washer, be sent to again and jump that the ore deposit machine is selected, dewatered drying, risen in the barite storehouse by bucket elevator again;

(3) by electro-vibrating feeder material is sent in the Raymond mill material machine and ground, be ground to 325 order to 600 orders;

(4), the 325 orders-600 purpose barite dry powder through grinding hangs in mixing cirtern, with water and blanc fixe furnishing slurry by a certain percentage, adds medicament, enters the buffer barrel stirring by certain solid content;

(5), squeeze into main frame by electric diaphragm pump and carry out wet grinding, in process of lapping, carry out the medicament titration, prevent that slurry is solid, institute's defibrination material flows into vibrations and is sieved to bucket to be checked, the slurry storing tank of being allowed for access after the assay was approved;

(6), the slurry in the slurry storing tank being squeezed into the second vibratory sieve by screw pump filters;

(7), then squeeze into the logical heat exchanger that enters of oven dry bucket, carry out drying and processing, after smashing the slurry of oven dry, hammer as requested carries out classification by grader by shattering, fine powder after the classification enters bag filter, enter automatic packaging machine, packed product introduction product warehouse after being laid by deduster and pulse.
