Aeolian sand reuse antique brick and its production method

Abstract

The invention discloses an aeolian-sand-reutilized antique brick and a production method thereof. The antique brick is prepared from 40-45 wt% of eolian sand, 10-15 wt% of perlite, 10-15 wt% of diatomite, 15-18 wt% of clinker, 8-10 wt% of argil, 5-10 wt% of coal gangue and 0.2-0.5 wt% of nickel powder. The production method comprises the following steps: purchasing raw materials, preparing the raw materials, pulverizing, screening to obtain undersieves, adding water, uniformly mixing, discharging sand soil into a plate feeder through a wheel loader, treating in a stone-removal double-roller machine, grinding in a grinding double-roller machine, milling in a ball mill, screening through a drum screen, sending the undersieves into a double-shaft stirrer, adding water, uniformly mixing, screening, and carrying out magnetic separation iron removal; delivering into a slurry servo tank by a slurry plunger pump and a pneumatic diaphragm pump; delivering into a spray drying tower by a plunger pump, and drying; and carrying out sintering forming.

Description

technical field

[0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and in particular relates to a method for preparing antique bricks by using aeolian sand and the prepared antique bricks. Background technique

[0002] Aeolian sand is sandy soil formed on the surface after natural wind transport, grading, and precipitation. Its particles are uniform, fine, and stable in composition. The main mineral is feldspar mixed with quartz, mica, etc.

[0003] The total area of ​​China's deserts is about 700,000 square kilometers. If including the Gobi of more than 500,000 square kilometers, the total area is 1.28 million square kilometers, accounting for 13% of the country's total land area. The arid region in Northwest China is the most concentrated area of ​​deserts in China, accounting for about 80% of the total desert area in the country, and the desertification of the land has made the land unusable for cultivation. Especially in the Kubuqi...
