Process for producing ceramic tile by using coal gangue(collyrium)

Abstract

A method for using coal gangue to produce ceramic tile uses waste coal gangue, alta-mud, talc, fused rock, zinc oxide, feldspar powder and quartz powder, to be stored, broken, loaded on to fork lift, weighted, transmitted via belt, grinded with water, fed into suspending pool, fed into slurry pump, screened to remove iron, fed into slurry pool, fed into slurry pump, made into powder in atomization drying tower, aged in storage chamber, shaped in press machine, fed into atomization drying tower via slurry pump to be atomized and dried. When in use, the powder is fed from material chamber, dried in roller furnace, glazed, sintered in roller furnace, polished, packed and stored.

Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to a method for producing ceramic tiles by using coal gangue (kaolinite). Background technique

[0002] At present, the known cement tiles and ordinary clay tiles have an average water absorption rate of 13-18%, a compressive capacity of 1800-2200N, and frost resistance performance. 4016kg / m 2 , The color is easy to fade and other disadvantages by spraying. Contents of the invention

[0003] In order to overcome the existing cement tiles, the average water absorption rate of ordinary clay tiles is 15-18%, the compressive capacity is 1800-2200N, and the anti-freeze performance has the phenomenon of shedding, bursting, corner dropping, and edge dropping, and the weight load on the house surface is 36. -4016kg / m 2 , The color is easy to fade and other deficiencies by inkjet printing. The invention provides a method for producing porcelain tiles by using coal gangue (ka...
