Technique for sintering color sand from basalt particles

Abstract

The invention relates to a technological method for burning festoon sand with basalt particle, which comprises the following steps: stirring, preheating, perching and cooling. The technological method is characterized in that: in the preheating and the perching steps, the stirred materials are preheated and perched in a preheating roller and a perching roller by using the hot wind provided by a hot blast stove. The technological method for burning festoon sand with basalt particle has the following advantages and active effects: 1. In the invention, coal is taken as raw material; therefore, energy is saved. 2. By adopting the purified wind with constant temperature and constant hot wind to perch the material, the material purification is ensured. 3. The diameter of the roller can be adjusted according to the material yield; therefore, the yield of the production has a certain assurance. 4. The preheating and perching effect is good. 5. The material can be directly packed after being cooled by a cooling roller; therefore, the complicated turning and drying work is avoided. 6. The festoon sand is ensured that the color is even and can not fade for a long time. 7. The technological method for burning festoon sand with basalt particle can be fitted with a coaling machine, an automatic slagging machine and dust collecting equipments, thus not only saving the labor but also meeting the environment protection requirement.

Description

Technical field: [0001] The invention relates to a production method of colored sand, in particular to a process method of sintering colored sand with basalt particles. Background technique: [0002] In the construction industry, with the popularity of high-end residential areas and a large number of sloping roofs, colored sand tiles are becoming more and more popular. The colored sand tile is manufactured by laying a layer of colored sand evenly on the asphalt felt at high temperature, and then cooling, rolling and other production processes. The production process of colored sand mainly has the following four stages: stirring, preheating, calcination and cooling. Stirring is to uniformly attach the pigment to the surface of the sand at room temperature; preheating is to keep the stirred material at a temperature of 200-220°C for 20 minutes; calcining is to heat the preheated material at 400-420°C ( According to the requirements of different pigments, the temperature can ...

Problems solved by technology

The disadvantage of this process is: the material cannot be laid too thick on the conveyor belt, the air will not penetrate the material if it is too thick, and the drying will be uneven, so the final color of the material will be inconsistent, which will limit the output
