A method for making building material bricks by reusing tailings slag

Abstract

The invention discloses a method for re-utilizing tailing slag to manufacture a building material refractory block and relates to the technical field of energy manufacturing. A tailing slag refractoryblock manufacturing device which comprises a bottom support plate and a lifting shaft, wherein the bottom support plate is horizontally fixed on the ground; a support ribbed plate erected at the topend of the bottom support plate is fixed at the top end of the bottom support plate; a first transverse beam plate horizontally fixed is arranged in the middle of the support ribbed plate; a second transverse beam plate parallel with the first transverse beam plate is arranged at the top end of the support ribbed plate; and a penetrating circular hole is formed in the middle of each of the secondtransverse beam plate and the first transverse beam plate. Support blocks horizontally fixed are mounted in the middles of rollers on the two sides, are arranged on the inner ring of a conveyor belt,and are fixed in the middles of the top ends of roller brackets, so that when a pressing block is pressed downwards, the support blocks support the top surface of the conveyor belt, and the conveyor belt serves as the bottom surface of a cavity to be supported in a steadier and firmer manner.

Description

technical field [0001] The invention relates to the technical field of energy production, in particular to a method for making building material bricks by reusing tailings slag. Background technique [0002] Tailings slag is the residual gangue and ore left after the metal ore is sorted by the concentrator. Usually accounts for 50%~90% of the total ore. The main chemical components are silicon dioxide, iron oxide, aluminum oxide, calcium oxide, etc., and some also contain ferrous metals or rare metals. Generally, it is discharged from the concentrator in the form of slurry, and the particle size is usually 0.001~1mm. After drying, it is easy to raise dust and pollute the air environment. The main method is to build dams for storage and disposal. It can be recovered from non-ferrous metals or rare metals, or used as filling materials and manufacturing building materials. [0003] Existing patent No. CN201220150618.2 discloses a hydraulic brick-making demoulding machine an...
