Rotary kiln and method for producing calcining color frit using rotary kiln

Abstract

The present invention discloses a rotary kiln and method for producing calcined color frit therewith. The rotary kiln includes inclined lined cylinder with material feeding port in the head, drive system, flue with chimney, temperature metering unit inside the cylinder, heat source in the tail and discharge port in the tail. During production, the mixed raw material is fed to the inner hearth and rolled from head to tail while the cylinder is rotated and the high temperature gas flows from tail to head, so that the material is preheated and high temperature calcined to become color frit, which is discharged from the tail and cooled. The present invention has high yield and low cost.

Description

technical field [0001] The invention relates to a kiln and a production method for calcined colored glaze, in particular to a rotary kiln for calcined colored glaze and a production method for calcined colored glaze using the rotary kiln. Background technique [0002] As we all know, the traditional method of producing ceramic colored glazes is to mix and crush chemical raw materials according to a certain proportion, then put them into a closed sagger and send them to the kiln for calcination. washing), drying, and packaging, no matter what kind of kiln is used to calcinate color materials, it is inseparable from saggers, kiln cars (push plates) and other kiln furniture. The labor intensity is high, and the production cost cannot be effectively reduced.
