Embodiment Construction

[0017] Combine below figure 1 , figure 2 Introduce the present invention in detail:

[0018] The tandem ultra-fine two-wheel airflow classifier system includes vertically arranged upper and lower bodies and a feed chamber 41 formed in the upper body 42, and the upper and lower bodies are respectively provided with rotating hollow runner devices 2. The rotating wheel device 2 is rotated by the rotating shaft 3 driven by the motor 5. The powder entering the feeding chamber is under the action of negative pressure, and the finer powder flows in from the outside of the rotating wheel device of the rotating upper body. The inner chamber of the runner device then flows into the discharge chamber arranged in the upper body from the inner chamber of the runner device, and then flows out from the discharge chamber; the coarser powder in the feed chamber moves along the upper The outer side of the runner device of the body flows down to the outer side of the runner device of the lowe...

Abstract

The invention relates to a fluidized bed airflow mill, in particular to a series type superfine dual-wheel airflow classifier system comprising an upper machine body and a lower machine body arranged vertically, and a feeding cavity molded in the upper machine body, wherein a rotary hollow runner device is arranged in each of the upper machine body and the lower machine body, finer powder entering the feeding cavity flows into the inner cavity of the runner device from the outer side of the rotary runner device in the upper machine body under the effect of negative pressure, then flows into a discharging cavity arranged in the upper machine body from the inner cavity of the runner device, and then discharges from the discharging cavity; thicker powder in the feeding cavity flows downwards to the outer side of the runner device in the lower machine body along the outer side of the runner device in the upper machine body under the effect of negative pressure, and the runner device in the lower machine body further classifies the thicker powder. According to the system provided by the invention, the milled powder can be classified twice via the two vertical runner devices, so that classification efficiency is improved and classification effect is also improved.

Description

technical field [0001] The invention relates to the technical field of dry powder grinding and powder crushing and classification, in particular to a serial ultrafine two-wheel airflow classifier system of a fluidized bed jet mill. Background technique [0002] Due to their excellent performance, ball mills and pulverizers have won the reputation of researchers and business owners in the field of material ultra-fine and grading. With the sudden emergence of new energy and new material industries, the market demand for the above-mentioned machines is increasing rapidly. Increased, and its performance and quality requirements are becoming increasingly stringent, especially in developed countries such as Europe and the United States have more stringent requirements. With the development of technology, jet mills have been recognized by more and more manufacturers for their low energy consumption, environmental protection and other excellent performance. However, the classificat...
