Footpath, its center point-blank, in grate plate is evenly equipped with elongated hole or circular hole with the rear center of quill shaft 110；
The width of the elongated hole or the diameter of circular hole be less than the diameter that the minimum mill filled in ball mill is situated between three/
Two, preceding grate plate 104 and rear grate plate 106 can prevent mill is situated between to enter preceding quill shaft 102 and rear quill shaft 110；
202 materials of mill Jie include aluminum oxide, zirconium oxide, stainless steel, carbon steel, manganese steel etc., and shape includes spherical and circle
Cylindricality；
Mill Jie 202 is filled into mill tube by ball-loading hole 113, and its volumetric filling ratio is between 60% to 85%；
The material collecting device includes charging aperture 114, discharging opening 109 and impurity discharging port 112；Crushing rear material passes through rear quill shaft
110 enter material collecting device by charging aperture 114, and product is pumped collection, impurity (broken ball, bead and thick material) by discharging opening 109
Because gravitational settling effect is discharged into impurity discharging port 112.
Preferably, the forced feeding machine 101 is to force powder material to feed by the way that spiral and compressed air are common
In mill tube.
Preferably, the mill is situated between 202 volumetric filling ratios 60% to 85%.
Preferably, the grate plate includes preceding grate plate 104 and rear grate plate 106.
Preferably, the material collecting device has charging aperture 114, discharging opening 109 and impurity discharging port 112, impurity (broken ball, bead
With thick material) it is discharged into impurity discharging port because of gravitational settling.
Beneficial effect：The present invention uses superelevation filling rate using being situated between for mill, makes the pulverization principle of ball mill by leave
Based on impact comminution, be changed into grinding based on friction, improve crush efficiency, Chinese medicine, ore, chemical industry can be achieved former
The ultra-fine grinding of the materials such as material.High fill-ratio improves the center of gravity of grinding machine, is more nearly mill tube center line, makes grinding machine torque significantly
Reduce, not only increase crush efficiency, realize ultra-fine grinding, while having reached the purpose of noise reduction and energy-conservation.

Embodiment
For the ease of understanding the present invention, with reference to specific embodiment, the present invention will be described in more detail.The present invention
It can realize in many different forms, however it is not limited to the embodiment described by this specification.On the contrary, providing these embodiments
Purpose be make understanding to the disclosure more it is thorough comprehensively.
Unless otherwise defined, technology all used in this specification and scientific terminology are led with belonging to the technology of the present invention
The implication that the technical staff in domain is generally understood that is identical.Used term is to be in the description of the invention in this specification
The purpose of description specific embodiment, is not intended to the limitation present invention.
By under same operational factor, mill of the same race be situated between and material of the same race be ground, and reach same equigranular in product
In the case of distribution, the present invention and the yield with the commercially available dry method continuous ball mill of size, unit work consumptiom, noise are contrasted,
To embody the features of the present invention and advantage.Two kinds of ball mill parameter comparisons are as shown in the table：
The grinding machine parameter comparison of table 1
Both the above grinding machine is respectively adopted extra-fine grinding is carried out to insect medicine cicada slough, and to equipment maximum production, unit energy
Consumption and grinding machine noise are tested and calculated.30 μm of 15 μm of target product D50 ＜, D90 ＜, for convenience of material collection and control thing
Material fineness rewinding mouth rear connects a generic hierarchical machine (3KW), bag-type dust (1.5KW) and centrifugal blower (11KW).Specifically
Operation is as follows：
Operation principle：Cicada slough after tens of kilograms of coarse crushings is poured into forced feeding machine, then starts ball mill, grader successively
And blower fan, finally start forced feeding machine and carry out feeding.Grader rotating speed is adjusted, stock product granularity in bag-type dust is reached
It is required that, the thick material under grader is returned into forced feeding machine, after grinding machine is stable, gradually increases giving for forced feeding machine
Doses, on the premise of grinding machine is stable, draws maximum production, and record grinding machine noise and use respectively with noise meter and ammeter
Electricity.Aforesaid operations are repeated for commercially available ball mill.It is computed showing that performance comparison table is as follows：
The grinding machine performance comparison of table 2
Contrasted by above-mentioned parameter, it is evident that the present invention is in yield, specific energy consumption, noise and product bulky grain side
Face is substantially better than commercially available ball mill, not only increases crush efficiency, realizes ultra-fine grinding, while having reached the mesh of noise reduction and energy-conservation
