Abstract

A rotator of an angle type grinder is composed of a rotator hub and a cutting row. At least two cutting rows which are formed in the same shape and uniformly and symmetrically arranged along the centre line of the cross section of the rotator hub are fixedly disposed on the outer cylinder surface of the cutting rows. The impact disintegration strength of the angle type grinder to materials is relatively weak, aggregates meet the required granularity of the process stipulation are speeded up to pass through a screen, and further impact disintegration rate of the aggregates by the cutting rows is reduced. Consequently, the rotator of an angle type grinder is particularly adapted for breaking work of crushed sheet-like aggregates with the relatively large granularity and relatively high requirements of evenness, which is simple in structure and convenient in manufacture.

Description

A kind of rotor of inclined shaft type grinder

Affiliated technical field

The utility model relate to a kind of can be big relatively to granularity, size reduction machinery that the demanding broken laminar material of evenness carries out the powder operation, especially for a kind of rotor of inclined shaft type grinder.

Background technology

At present, in the known pulverizer commonly used, material is impacted the active rotor that disintegrates, two kinds of patterns are structurally arranged substantially: one, hammer slice type, four groups of some shapes are identical, the hammer leaf of equidistant arrangement, being installed on the rotor hammer carrier symmetrically, and stagger in adjacent set hammer leaf position in the axial direction; Its two, hock type, some shapes are identical, the hock of equidistant arrangement, being arranged on the rotor Moving plate on the concentric circles that three radiuses do not wait symmetrically.The rotor of above-mentioned two types pulverizer commonly used when work, the hammer leaf of numerous quantity or hock, with decide tooth plate, fixed tooth disk cooperates, the impact disintegration intensity that material is subjected to is very big, can in the short time broken laminar material pulverizing be disintegrated to micro mist.Thereby, be not suitable for, evenness demanding broken laminar material big relatively especially and carry out the powder operation granularity.

Prior art is quoted as proof:

1, utility model patent ZL patent No. 200620034458.X " adjustable beater disintegrating machine ";

2, the utility model patent ZL patent No. 99231776.2 " hock type pulverizer ".

Summary of the invention

Above-mentioned disadvantage for fear of existing rotor mill known technology, the utility model provides a kind of rotor of inclined shaft type grinder, that a kind of rotor specially of this inclined shaft type grinder is applicable to is big relatively to granularity, the demanding broken laminar material of evenness carries out the powder operation, and simple in structure, make easily.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of rotor of inclined shaft type grinder is made up of rotor hub and blade row, shape identical and on rotor hub cross-section center line distributing position symmetrically, quantitatively be no less than two blade row, be arranged on its external cylindrical surface; Blade row connects into the framework of H shape by flat board in the middle of two side tool plates and, dull and stereotypedly therebetween meets material face, outer part radially, evenly is provided with some cutter pieces; Meet material face place at blade row by the side tool plate of material inlet end, be the cutting edge shape, the side tool plate of its other end is met material face place, and the plane is rectangle.

The beneficial effects of the utility model are: its blade row of a kind of rotor of inclined shaft type grinder and the cutter number of blocks that is arranged on the blade row are few, to the weak relatively H shape framework blade row of the impact disintegration intensity of material when rotating at a high speed, the wind-force that is produced is big, can make the material that meets process stipulation requirement granularity quicken to pass screen cloth, reducing it is subjected to blade row further to impact the probability of disintegration again, be specially adapted to, evenness demanding broken laminar material big relatively and carry out the powder operation granularity, and simple in structure, make easily.

The specific embodiment

Embodiment 1 Fig. 1 is a kind of rotor of the inclined shaft type grinder that the utility model is implemented, by rotor hub (1) be arranged on rotor hub (1) external cylindrical surface on, shape is identical and on its cross-section center line distributing position two blade rows (2) symmetrically form; Blade row (2) connects into the framework of H shape by flat board in the middle of two side tool plates and, dull and stereotyped therebetween material face, the outer part radially, four cuboid tack cutter pieces that equidistant vertical Boulez shape is identical of meeting; Meet material face place at blade row (2) by the side tool plate of material inlet end, be the cutting edge shape, the side tool plate of its other end is met material face place, and the plane is rectangle.

The another kind of blade row profile that embodiment 2 Fig. 4 implement for the utility model for adapting to the needs of different performance material powder, can be replaced with the wedge shape cutter piece of band roundlet nock with above-mentioned tack cutter piece.

Claims
