Method for preparing bricks and plates by utilizing granite leftovers of mountain flour and rock ballast

Abstract

The invention relates to a method for preparing bricks and plates by utilizing granite leftovers of mountain flour and rock ballast, sequentially comprising the steps of feed preparation reaction of the granite leftovers, material stirring, compression moulding, and steam evaporation. The method is characterized by adding selected granite leftovers of wet mountain flour and rock ballast into a reaction tank for reacting and precipitating; and then adding calcium desulfurization, carbide slag, lime powder and coagulant, utilizing a stirrer to stir the materials evenly under the steam condition; then utilizing a brick machine to carry out compression moulding; and finally putting well-compacted products into a still kettle to evaporate thoroughly in high-pressure steam, thus obtaining the bricks and the plates. The invention reasonably utilizes wastes and protects environment, the product thereof is not easy to break, the cost is low and the method is easily accepted by extensive information users.

Description

Technical field: [0001] The invention belongs to the field of comprehensive utilization of industrial solid wastes, and more specifically relates to a method for making bricks and boards by utilizing granite leftover stone powder and gravel slag. Background technique: [0002] The prior art has not yet utilized the granite leftover stone powder and gravel to make bricks and panels. With the development of the stone industry, its granite leftovers have not been rationally utilized, resulting in waste of resources and deterioration of the ecological environment; existing Brick and plate making methods mainly use fly ash, sand and other small amounts of chemical materials as raw materials, and the manufacturing process is complicated. Due to the large silicon content, the products are easily broken, and the waste of resources is caused, and the cost is generally relatively high. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies o...
