Embodiment 1

[0015] First, crush the mined red shale to 100 mesh with a Raymond machine, then add water and granulate the red shale powder to 20 mesh to keep the water content below 9%, and put the granulated red shale powder into the warehouse for aging After 10 days, use a 1,300-ton press to press the red shale granulated powder under a steel mold of any shape, and finally, burn the shaped glazed tiles in a roller kiln at 1,200 degrees Celsius for 12 hours to obtain Finished glazed tiles.

Embodiment 2

[0017] First, crush the mined red shale to 120 mesh with a Raymond machine, then add water and granulate the red shale powder to 25 mesh to keep the water content below 9%, and put the granulated red shale powder into the warehouse for aging After 10 days, the red shale granulation powder is pressed into a steel mold of any shape with a press machine of more than 1,300 tons, and finally, the glazed tiles are fired in a roller kiln at 1,200 degrees Celsius for 12 hours. Obtain finished glazed tiles.

Abstract

The invention discloses a process method for dry powder type pressing preparation of a vitreous tile from red shale. The process method includes the steps: smashing the red shale to 100-120 mesh by a Raymond machine, carrying out water addition and granulation of the red shale powder to 20-25 mesh, allowing the water content to below 9%, warehousing the granulated red shale powder, staling for 10 days, carrying out pressing molding of the red shale granulated powder in a arbitrary-shape steel-prepared mold by utilizing a more-than-1300-ton pressing machine, and sintering the molded vitreous tile in a roller kiln with the temperature of 1200 DEG C for 12 h. The process method has the advantages in the production that only one kind of shale is required; moreover, the raw materials are more abundant; and the process method for dry powder type pressing preparation of the vitreous tile can allow trace water to be directly added for granulation after smashing, has simple production operation, and also plays a big role in saving resources.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a process method for pressing glazed tiles with dry powder of red shale. Background technique [0002] At present, the main method of producing and processing glazed tiles on the market is: using more than two kinds of soil, ball milling into a mixed slurry (with a moisture content of more than 50%) through a ball mill, and then granulating with a spray tower (with a moisture content of less than 9%) and putting it into the warehouse for stale use. It is pressed into shape by a press, and finally fired in a roller kiln. Glazed tiles prepared by this wet method are porcelain, and have poor performance in heat insulation and antifreeze. [0003] As a kind of clay rock, red shale has a complex composition. In addition to clay minerals (such as: kaolinite, montmorillonite, hydromica, Baillite, etc.), it also contains many clastic minerals (such as quartz, feldspar, etc....
