The specific embodiment

Produce the embodiment of siliceous shale stoneware glazed tile, be further described by accompanying drawing 1 process chart:

At first will excavate or the siliceous shale of explosion is sent into hammer and pulverized (1) machine, and by self 4-5mm sieve aperture (summer can the appropriateness watering help broken with reduce dust) to send into secondary vibration sub-sieve (2) one sieve sheet aperture be 3mm, two to sieve the sheet apertures be 1mm.Thereby make on the sieve sheet coarse particle return go into mill, and a sieve down two sieves go up particle and generally be about 3-1mm and send into particle Ji Chang (4-1) and be stand-by particulate material.The two sieves down particles powders that enter grinding (3) general requirements 80-90% are about that to send into powder Ji Chang (4-2) below the 0.15mm stand-by.Again particle (accounting for the 20-30% of total amount) and powder (accounting for the 80-70% of total amount) measures respectively to enter after (5) and add water stirring (6) moisture and should be controlled at 6-10%, entering the general digestion time of ageing (7) after the stirred for several minute is 24-48 hour, gets final product extrusion forming (8) (annotate: hydraulic press is generally chosen the type of 80-100T) (9) to be dried.In addition: its glaze should be chosen or make by oneself (10) once-firing high-quality color glaze that do not chap.Can glazing (11) but loading of kiln once-firing (12) (suggestion should be selected and build advanced at present energy-conserving and environment-protective brick and tile tunnel cave) after treating, its temperature is controlled at 1000-1100 ℃.During kiln discharge: should divide high-class product and certified products sign indicating number to go into finished product (13) storehouse or direct marketing.
