An active activator atomization device for metal tailings grinding system

Abstract

An active exciting agent atomization device for a metal tailing grinding system comprises a spray gun, an air-liquid mixing nozzle, a liquid supply system and an air supply system, wherein the spray gun is composed of an inner tube and an outer sleeve in an assembly welding mode, an air intake ring cavity is formed between the outer sleeve and the inner tube, one end of the air intake ring cavity is a closed end, the other end of the air intake ring cavity is an open end, the spray gun is installed on a connection pipeline between a vertical mill and a bag type dust collector, the side wall of the position, located outside the connection pipeline, of the outer sleeve is provided with an air inlet, and the end, located outside the connection pipeline, of the inner tube stretches out of the outer sleeve to form a liquid intake end; the air-liquid mixing nozzle is installed at the open end of the spray gun; the liquid supply system is connected with the liquid intake end, and the air supply system is connected with the air inlet. The device can be used for effectively and uniformly atomizing and spraying active exciting agents in the pipeline, thereby well guaranteeing uniform mixing of the active exciting agents and micro powder finished products of raw materials, and guaranteeing that the active exciting agents can be effectively attached to interfaces of particles of the micro powder finished products. The device prevents a hot air environment in the mill from affecting performance of the active exciting agents, thereby reducing volatilization and losses of the active exciting agents. The device can be used for regulating and controlling the additive amount, and therefore different production requirements can bet met.

Description

technical field [0001] The invention belongs to the field of grinding equipment for cement industry, and relates to a micropowder treatment technology. In particular, it refers to an active activator atomizing device suitable for working in a high-density dust environment in a vertical roller mill grinding system. Background technique [0002] Vertical mill is an energy-saving grinding equipment widely used in cement, steel, electric power and other industries. In order to ensure that the finished micropowder after the vertical mill grinds the raw materials can have a higher activity index and can be comprehensively utilized with large dosage and high added value, it is very important to control the addition method of the active activator. It is well known that the potential activation properties of materials can be fully utilized through physical excitation and chemical excitation. At this stage, the physical activity of the material is stimulated by forming a material be...

AI Technical Summary

Problems solved by technology

The shortcomings of this active activator addition method are: extensive metering method; belt sticking is easy to occur; active activator is difficult to mix evenly with raw materials; because it is added before the mill, the active activator is easy to volatilize in the hot air environment in the mill , The loss is large, which seriously affects the adhesion effect of the polymer in the active stimulant and the particle interface of the finished micro-powder, which in turn affects the further development of the potential activity of the finished micro-powder of the material
