Filter, the filtering of super fine can increase the loss of power consumption and filtration core, and yield rate is low, adds the cost of finished product.
Existing airflow mill, such as：Chinese patent application publication No.：The A of CN 105312144 disclose " ultra micro air-flow
Grading mill ", it is a kind of mechanical crusher crushed with jump bit, ultra micro air current classifying mill include connecting simultaneously source of the gas with
The material inlet end that supply stream enters, and the material outlet end for fine powder discharge, disintegrating area directly connects to be formed with graded region
Pulverizing chamber, air-flow enter the pulverizing chamber of ultra micro air current classifying mill, rotating disk with feeding from material inlet end by rotating disk bottom
Driven and rotated by turntable motor, by between the liner plate of the jump bit on rotating disk and disk edge on mill chamber inwall
Collision makes material conglomeration be broken up and crushed for several times.In order to improve crushing effect, shape, quantity, height and its position of jump bit
Putting optimised can be designed as increase and the contact area of material, such as：Including with the trapezoidal of oblique angle, or there is certain altitude
Cylindricality.In addition, it is also possible to consider the gap reduced between jump bit and liner plate.Generally, liner plate is the gear ring with internal tooth, is subtracted
Small above-mentioned gap advantageously increases the impact dynamics between jump bit and liner plate, promotes powder to crush.The fine powder being crushed
The graded region where effect backspin is raised to grading wheel is submitted in air-flow.Now, the grading wheel of rotation is driven by classification wheel motor
Fine powder is classified using centrifugal force field caused by its blade, sufficiently fine fine silt can follow air-flow to enter through grading wheel
Enter volute area and discharged from material outlet end, coarse granule can then be graded wheel and block and in its periphery convolution.But because it is adopted
Crushed with jump bit, shortcoming is not extremely concentrated for the size distribution of finished product, and it is higher to cross fine powder ratio.
Existing injector-type mill, such as：Chinese patent application publication No.：The A of CN 103025433 disclose " injecting type
Its separation wheel of grinding machine " is horizontal positioned, is fed on top, nozzle has collision component in bottom.Its invention solves container
