Abstract

The utility model relates to a ring mill. A lining board adopts a composite structure and is provided with a wear-resistant inner layer of the lining board, a copper powder and adhesive layer and an outer layer of the lining board in sequence from the inner part to the outer part, and the outer layer of the lining board is fixedly connected with a machine body. A milling ring is divided into a plurality of fan-shaped rings, the upper layer surface of one end of each fan-shaped ring is provided with a hollow layer which forms a star shape and the lower layer surface is a solid layer, and the lower layer surface of the other end is correspondingly provided with a hollow layer with the same size and the upper layer surface is a solid layer. The solid layer of the connection point of each fan-shaped ring is just arranged above the hollow layer of another fan-shaped ring to form definite join opening connection. The milling ring is easily changed or repaired, and the service life of the lining board is enhanced. The cost can be reduced, and the expenses can be saved.

Description

A kind of annular grinder

The utility model relates to a kind of powder process machinery, a kind of annular grinder of more specifically saying so.

Annular grinder is a kind of important powder process machinery, this machine utilizes rotor rotated to drive and grinds to encircle material is carried out impact grinding, rolled between ring and the liner plate and the effect of milling such as shearing grinding again by the material after impacting, make the granularity that material reaches to be needed, often be used to fragmentation, the ore of hardness in the grinding.The liner plate of annular grinder is a high abrasion resisting material, and price is very expensive, so former annular grinder all drops to minimum point as far as possible with liner plate thickness, in order to save material, reduces production costs, and causes the liner plate of a lot of annular grinders often broken.But, can increase user's use cost again if liner plate thickness is thickened.At present also there are many practical difficulties in compound casting, difficult realization the, and the working face of annular grinder liner plate is internal layer, the poorest part of compound casting effect exactly.The annular grinder liner plate is a high-abrasive material, is difficult to it is carried out machining, because difficult processing, liner plate and casing applying leakiness also often cause liner plate to damage.Grinding ring also is the consumable accessory of annular grinder, and after annular grinder started, the stone roller ring directly impacted liner plate and also causes liner plate often to break.And grinding ring is a full circle, is enclosed within on the main shaft of rotating disk, and rotating disk is again one by one overlapping, and is also inconvenient for maintenance.

The purpose of this utility model aims to provide a kind of change with comparalive ease or ring is ground in maintenance, improves the service life of liner plate, both can reduce cost, but the annular grinder of cost saving again.

The purpose of this utility model realizes by following manner:

Stone roller ring set of the present utility model places on the little axle between the rotating disk, and in rotating disk placed liner plate, rotating disk then was placed on the main shaft one by one, and liner plate is made into tubbiness, and employing composite construction, be followed successively by the liner plate wear resistant inner layer from inside to outside, can make the tight copper powder tack coat of inside and outside two-layer applying, the liner plate skin, liner plate is outer to be connected and fixed with body, grind ring and then be divided into the plurality of sector ring, the aspect file has a dead level on each eccentric circular ring one end, becomes

Shape, subsurface then are real layer, and its other end subsurface is also correspondingly filed and had a dead level of the same size, last aspect then is real layer, make its each eccentric circular ring junction in fact layer just in time be positioned on another eccentric circular ring dead level, and fixing, forms certain mouthful connection of taking.

In addition, stone roller ring internal layer of the present utility model adopts general steel plate, and skin then adopts high-abrasive material to make.

The utility model is because it grinds the special construction of ring, make its in maintenance, change conveniently, and in use, grind ring and directly liner plate do not impacted, also improved the service life of liner plate.Also, so also just improved the service life of annular grinder, reduced use cost because the composite construction of liner plate has improved shock proof intensity of liner plate and toughness widely.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Accompanying drawing 1 is the front view of stone roller ring of the present utility model;

Accompanying drawing 2 is an eccentric circular ring front view in the stone roller ring of the present utility model;

Accompanying drawing 3 is an eccentric circular ring longitudinal sectional view in the stone roller ring of the present utility model;

Accompanying drawing 4 is the utility model lining plate structure diagrammatic sketch;

Configuration diagram when accompanying drawing 5 grinds ring with the liner plate work in combination for the utility model.

Shown in accompanying drawing 1,2,3, stone roller ring 1 of the present utility model is divided to make three eccentric circular rings 2, and the last aspect file of each eccentric circular ring 2 one end has a dead level 3, and subsurface then is real layer 4, becomes

Shape, the also corresponding file of its other end subsurface has a dead level 3, and the aspect that then goes up is real layer 4, and then its each eccentric circular ring junction layer 4 in fact just in time places on another eccentric circular ring dead level 3, and fixes by screw, forms certain mouthful connection of taking.

Stone roller ring 1 of the present utility model, internal layer 5 adopts general steel plate, and outer 6 then adopt high-abrasive material to make, and make it more wear-resisting, have increased service life, when changing grinding ring, as long as pull down two screws arbitrarily, can unload and grind ring.

Shown in Fig. 5,6, liner plate of the present utility model is made into tubbiness, it adopts lamination layer structure, from inside to outside, is followed successively by liner plate wear resistant inner layer 7, copper powder tack coat 8, liner plate skin 9, liner plate skin 9 is general steel plates, liner plate wear resistant inner layer 7 is a high-abrasive material, connect with screw between them, and copper powder tack coat between the two is adhesive and copper powder that it is tighter that inside and outside two layers of material is fitted, copper powder can play filling effect, the heat that produces in the time of conducting the high-abrasive material abrasive dust again.

As shown in Figure 6, grind and encircle on the 1 little axle 12 that is placed between the rotating disk 10, can be nested with a plurality of stone roller rings as required between two rotating disks, rotating disk then is placed on the main shaft 11 one by one, and places in the liner plate with rotating disk 10, during annular grinder work, main shaft 11 drives rotating disk 10 and rotates, and make stone roller ring 1 in the irregular rotation of rotating disk 10 intercropping, and material is constantly impacted between stone roller ring and liner plate, mill.
