Embodiment

[0023] A high-strength lime-sand brick and its production process. The raw materials are hard construction and industrial waste, machine-made sand (egg machine-made sand or mountain machine-made sand), medium-coarse sand (river sand), powdery waste, and cementitious material (cement) Composition, production steps include:

[0024] Step 1: Crushing each raw material separately requires the use of a crushing device;

[0025] The raw materials are added into the cylindrical box 2, and the raw materials can be ground through the interaction between the rotating fixed grinding disc 7 and the linkage grinding disc 9; the raw materials after grinding are crushed by the stirring blade 10 to obtain broken particles; when the broken particles When the particle size is not greater than 0.45cm, the broken particles are collected into the collection box 17 from the discharge hole 14, the filter screen 15, and the discharge pipe 16 under the action of centrifugal force;

[0026] The rotati...

Abstract

The invention relates to the technical field of artificial stone, and discloses a high-strength lime-sand brick and a production process. Raw materials include hard building and industrial waste, manufactured sand, medium and coarse sand, powdered waste and a binding material. The process includes 1) grinding and crushing each raw material with crushers to obtain crushed particles; 2) storing thecrushed particles in separated bins; 3) adding water into the crushed particles, mixing and stirring the materials to obtain a mixture; 4) subjecting the mixture to compression moulding to obtain a brick blank; and 5) subjecting the brick blank to steam pressing and curing to obtain a finished product of the steam-pressed lime-sand brick. The technical scheme mainly overcomes a problem that standard bricks adopted at present cause loss of cultivated land resources and harm to human bodies.

Description

technical field [0001] The invention relates to the technical field of artificial stone. Background technique [0002] With the rapid development of my country's economy, the demand for building bricks has doubled, especially the large number of demolition and construction projects in cities, making the demand for building bricks increasing. The standard bricks currently on the market mainly include clay bricks and shale bricks. Clay bricks are fired from clay, which requires excavation of cultivated land, resulting in a large loss of cultivated land resources; at present, my country has adopted relevant measures to limit the use of clay to make bricks to protect scarce cultivated land resources. Shale bricks are calcined from shale and coal gangue, and the residual sulfur dioxide in the finished products is harmful to the human body; at the same time, because shale bricks are easy to weather, their service life is limited. In summary, it is imperative to research and deve...
