The role of the tailings slag waste slag brick making machine process equipment binder:
Tailings slag waste slag brick making machine process equipment, inorganic binders commonly used in brick making in non-ferrous metallurgy include slaked lime, bentonite and their mixtures, etc., organic binders include neutral sulfurous acid pulp waste liquid, etc. Slaked lime is an additive with strong hydrophilicity and cementing ability, after adding slaked lime as raw material. It can increase the strength of the agglomerate and at the same time act as a flux. Bentonite has good expansibility, cohesiveness, plasticity and stability in hot state, which can ensure the strength of agglomerates and improve the thermal stability of agglomerates. Neutral sulfurous acid pulp waste liquid still has good fluidity at relatively low temperature, is easy to use, and can improve the strength of the pellet. Binders for sulfide concentrate briquetting are generally expected to act as slag-forming fluxes during smelting, so slaked lime, bentonite and their mixtures are often used.
Tailings slag waste slag brick making machine process equipment process:
There are two methods of tailings slag waste slag brick making machine process equipment, which are divided into hot pressed bricks and cold pressed bricks. Hot-pressed bricks are made by mixing normal-temperature pulverized coal directly with high-temperature roasted ore, heating the coal until it is fully softened, and precipitating a certain amount of colloidal bodies and then forming it under pressure. The process of this method is simple, the heat utilization rate is high, and no adhesive is required, but the quality of the brick ore is often not as good as that of the cold pressed brick method. Cold-pressed bricks are made by mixing, grinding, and compacting raw materials, coal powder, and adhesives at room temperature, and then pressing them into blocks. The purpose of milling is to make the mixture dense and plastic. The quality of grinding will affect the formation rate of pellets and the strength of pellets. Generally, it is enough to grind 3 times. The function of compaction is to press the joint abrasive into small balls and improve the strength of the milled abrasive. Brick pressing is to press and form the compacted grinding material in the tailings slag waste slag brick making machine process equipment.
Industry provides services:
