In this step, the configuration of described pulverizer can be beats hair style pulverizer or mill piece type crusher, its crushing process is to adopt current mixing method mode, in the hopper of pulverizer, install and connect water jet standpipe, so that blanking limit, limit water spray, make medicinal powder material fully moist, companion's pigment are broken, the uninterrupted of water be according to powder blanking amount number control the switch size of water pipe;
B, centrifuge dehydration
By the starchy wet mash of one-tenth, with braided fiber bag or cloth bag splendid attire and put into spin-dry in whizzer, dewatering time is 20-25 minutes, and the wet-milling water content after dehydration is 10-15%;
(3) sieving and grading
A, moistening screening, elect the semi-wet Powder screen after dehydration as 40-60 orders and 60-80 orders two kinds;
The choosing of b, water sieve, is mainly the above powder of screening 80-100 order, or sizing screening is 80-100 orders and more than 100-120 orders as required, and the powder that adopts water sieve to select also needs to carry out centrifuge dehydration for the second time;
C, by the moist powder classification after screening be packaged into 25 kilograms packed, and be transferred to entrepot storage and store;
(4) dry powder processing
A, wet-milling are dried, the moist powder of staged packaging is dried or dried, concrete drying mode is to adopt baking room electric heating air drying, moist powder to be put into solarization dish or hack is spread out, be placed on stoving rack, bake out temperature is 35-65 degree, and be 20-24 hours time of drying, and medicinal powder water content is 1-5%;
B, cooling down, carry out cooling down by the powder of oven dry, cooling 2-4 hours of natural temperature, and mechanical cooling down 1 hour, to natural temperature 25-30 degree, makes single original washing powder for described fireworks, double-basis powder product;
(5) finished product packing
With anti-electrostatic and moistureproof fiber woven bags, single original washing powder, double-basis powder after drying or drying are packed and be finished product warehouse-in.
In the course of processing of the present invention, do not change single original washing powder, the original intrinsic chemical molecular structure of double-basis powder, therefore do not change its physics and chemistry stability yet, just the physical structure of external form changes, and by original crystalline structure or grain pattern shape, after processing, has become pulverized structure shape, the density of respective physical structure also changes to some extent, by original tight type, become loose type, originally density is little, and after processing, its density increases.
Therefore, with single original washing powder, the double-basis powder for fireworks of the inventive method processing, substitute black powder and pyrotechnic composition in prior art, advantage and positively effect that it has are:
