Abstract

The utility model relates to a crusher for non-metallic materials with low and medium hardness (0-3.5 Mohs), which comprises a crushing unit, consisting of a conical rotor and a conical stator enclosing an out ring. Annular space is for crushing, and the conical rotor is composed of 2-3 layer tooling plates and the out rings thereof are provided with a plurality of blades. The inner surface of the conical stator is of a triangular and tooth shape. The conical rotor and stator has fulfilled the requirement of gap adjustment during superfine material crushing. The utility model ha advantages of favorable fineness, regularity, high efficiency, and convenient operation, widely applied to non-metallic minerals, medicines, chemicals and foods.

Description

Cyclone mill

The utility model relates to a kind of atomizer tool of nonmetallic materials.

At present, impact grinder is mainly used in pulverizes the low various materials of medium hardness (0～3.5 Mohs) by the time, kind more as hammer mill, bar type mill, room formula mill etc., but these machines all can not be regulated stator and gap between rotor.Require uniform material for particulate and the particulate pulverized less than 100 microns, can not regulate stator and gap between rotor and be difficult to realize.

At the weak point that exists of above-mentioned size reduction machinery, a kind of Cyclone mill that can regulate stator and gap between rotor of the utility model design.

Thinking of the present utility model: as micronizer, stator and gap between rotor are vital, and the needs of regulating the gap in the ultramicro grinding process have been satisfied in the exploitation of cone rotor and stator, and will reduce regulating step.Regulate stator and gap between rotor makes it less than 1 millimeter by the method that moves axially stator.For the material of pulverizing less than 100 microns particulate, so little gap is necessary.

The new technical scheme of this practicality is achieved like this: its structure is mainly formed crushing auxiliary by rotor and the stator that is enclosed in the outer ring, it is characterized in that the tapered rotor of rotor and stator system (3) and be enclosed in the taper stator (5) of outer ring, its tapering α is 7.5～15 degree, and its annular space is for pulverizing district (2).Diameter is d, highly is h, and tapering is that the cone rotor (3) of α is made up of 2--3 layer knife rest dish, and the cylindrical of its knife rest dish is equipped with several blades; Diameter is D, highly for H, tapering are that the inner surface of the taper stator (5) of α is made the triangle profile of tooth, taper stator (5) is fixed in the inner ring of upper box (6).Cone rotor (3) can be adjusted the pad height by changing spacing with the gap of taper stator, the method that moves axially stator that promptly reaches the lifting upper box regulates stator and gap between rotor makes it less than 1 millimeter, material pulverize the district cause between particle in by fierce helical form eddy current collide mutually, impact and the friction of stator wall and obtain pulverizing, the finished product after the pulverizing is pumped away through discharging opening (1) by the negative pressure exhausting system.

Advantage of the present utility model: owing to use the Cyclone mill of cone rotor and taper stator, regulate stator and gap between rotor makes it less than 1 millimeter by the method that moves axially stator, can pulverize material less than 100 microns particulate, be the low various materials of the nonmetallic ore of medium hardness (0～3.5 Mohs) by the time of a kind of pulverizing, have crush efficiency height, fine size and evenly (can reach 2～8um), power consumption province, advantage such as noise is low, fineness is easy to adjust.

Fig. 1 is structural representation of the present utility model.

Among the figure: 1, discharging opening; 2, pulverize the district; 3, cone rotor; 4, charge door; 5, taper stator; 6, upper box; 7, spacing is adjusted pad; 8, motor.

Below in conjunction with Fig. 1 the utility model Cyclone mill implementation process is described further: material is from reinforced.(4) enter in the machine, drive the cone rotor (3) of rotation at a high speed through narrow V belt, along the circumferential direction evenly disperse the pulverizing district (2) between back arrival cone rotor (3) and the taper stator (5), material is caused by fierce helical form eddy current and runs foul of each other, impacts between particle and the particle and pulverize with the flank of tooth friction of stator triangle profile of tooth pulverizing the district, its process from pulverize the top, district along helix until the bottom, the finished product after the pulverizing is extracted out by blower fan through discharging opening (1); When material does not reach fineness requirement, can adjust the washer height by reducing spacing, the method that moves axially stator of lifting upper box reaches the purpose of regulating stator and gap between rotor, makes it reach the requirement of fineness.

Claims (1)

1.
