Abstract
The invention discloses a mica raw material sorting process. The mica raw material sorting process includes the following steps that (1) primary screening is performed, specifically, a mica raw material is subjected to two-stage screening through a vibrating screen so as to remove impurities such as sediments; (2) crushing is conducted, specifically, the mica raw material obtained after primary screening is put in a counter-roll machine to be extruded and layered so as to obtain mica sheets; and (3) secondary screening is performed, specifically, the mica sheets are rescreened through a double-layer mesh-number screen so as to remove the sediments and quartz powder, and the sorted mica raw material is obtained. Raw material sorting is performed through the three steps of primary screening, crushing and secondary screening, the finally obtained mica sheets are consistent in thickness and sheet diameter, and damage to the qualities of the mica sheets in the prior art is avoided. Meanwhile, the tensile force of the mica sheets is increased, and the pulp yield is synchronously increased.
Description
Technical field
The invention belongs to mica manufacture field, be specifically related to a kind of mica material sorting technique.
Technical background
Mica is a kind of rock-forming mineral, is tabular, sheet, the column crystalline form of false six sides or rhombus usually.Color is different with the change of chemical composition, increasing and deepen mainly with Fe content.The characteristic of mica is insulation, high temperature resistant, glossy, physical and chemical performance stable, there is good thermal insulation, elasticity and toughness, have again and shelled into the performance with flexible transparent sheet, be widely used in the chemical engineering industries such as building material industry, fire protection sector, extinguishing chemical, welding rod, plastics, electric insulation, papermaking, bituminized paper, rubber, pearlescent pigment.
Mica paper is a kind of conventional insulating materials, and production process mainly comprises pulverizing, classification, slurrying, manufactures paper with pulp, shaping, squeezing, dry seven steps.Wherein manufacture paper with pulp, shaping, squeezing and to dry four steps be quite ripe operation in mica paper is produced, so the pulverizing of mica, classification and slurrying three operations are most important parts in whole mica paper production process, the quality of these three operations directly affects the quality and performance index that mica paper becomes paper.
At present, pulverize, classification is that conventional mica is selected materials method, generally adopt artificial naked eyes classification, hammer hammer is broken, and hand sieve removes silt; Smashing with breaker bar of bulk.But the method efficiency is low, disintegrating machine dnockout greatly reduces the soft right property of mica sheet itself, and graininess is many, and silt divides de-weak effect, large on the mica paper pulling force impact of manufacturing paper with pulp out.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of mica material sorting technique.
A kind of mica material sorting technique, comprises the following steps:
(1) sieve for the first time: adopt reciprocating sieve to carry out two-stage screening, to remove the impurity such as silt mica raw material;
(2) broken: the mica raw material after screening for the first time to be dropped into twin rollers, carries out extruding layering, obtain mica sheet;
(3) again sieve: adopt double-deck order number sieve again to be sieved by mica sheet, to remove silt, quartz powder, mica raw material must be sorted.
The reciprocating sieve of described step (1) is 4 mesh sieves, 8 order framework reciprocating sieves.
The double-deck order number sieve of described step (3) is 10 orders, the double-deck order number sieve of 12 orders.
Beneficial effect of the present invention: the present invention carries out material sorting by first screening, fragmentation, again screening three process, thinness, the sheet footpath of the mica sheet finally obtained are consistent, solve in the past to the damage of mica blade matter, also improve mica sheet pulling force, slurry yield also synchronously rises simultaneously; The mica sheet steady quality of the present invention's sorting, greatly can reduce silt and quartz powder content, the mica paper electric property of manufacturing paper with pulp out fullys meet industry technology requirement.
