Abstract

The utility model discloses a mechanical ring mill crushing classifier, belonging to the equipment technical field that crushes materials by rotating element, comprising a classifier in the upper part and a ring mill host machine in the lower part, the wheels and the track combining with the wheels mesh closely to be an arc structure; the upper two layers of the three-layer ring mill disc frames and the lower layer of the three-layer ring mill disc frames stagger strip position; the wheels produce centrifugal force, because the disc frame is driven electrically to rotate by host machine, the materials are rolled in the groove of the track to be crushed, due to the centrifugal force of the wheels. The utility model has the advantages of reducing the wear of the disc frame, effectively improving the fineness and output of crushing materials, improving crushing probability.

Description

The broken grader of mechanical type ring abrasive dust

(1), technical field

The utility model discloses the broken grader of a kind of mechanical type ring abrasive dust, belong to equipment technical field with the spinner member comminuting matter.

(2), background technology

The broken grader of existing machinery formula ring abrasive dust is generally Raymond mill, and the inside in existing Raymond mill pulverizing chamber is bearing arrangement, and adding oil spill covolume easily pollutes powder; And because of its reasons in structure for thermal sensitivity and fibroid material processing difficulties.

(3), summary of the invention:

1, goal of the invention: the purpose of this utility model is the deficiency at above technology, by to its structural improvement, provides a kind of product purity height, performance is good, efficient is high energy-saving desirable micro mist production equipment.

2, technical scheme: the broken grader of a kind of mechanical type ring abrasive dust, mainly form by the grader on top, the ring mill main frame of bottom.Ring mill main frame mainly comprises parts such as the auxilliary axle 1 of ring mill, ring millrind 2, ring emery wheel 3, ring mill track 4, rail support ring 5; Its ring emery wheel 3 and the ring mill track 4 that cooperates with it are the arcuate structure of tight engagement; Its ring millrind 2 is three layers and upper two layers and following one deck staggered positions.By main driven by motor ring millrind 2 rotations, make ring emery wheel 3 produce centrifugal force during use, rolled realization pulverizing in rail groove thereby powder encircles the centrifugal force of emery wheel 3.

Its course of work and principle are: raw material is in feeding device adds main frame, evenly fall into after rib 6 is broken up via breaing up on the bearing support in the engagement ring shaped slot of bull ring and ring mill track and grind, material is top-down through repeatedly grinding, drop at last on the spreading disk and to be thrown to rising passway and deliver to graded region by primary air, qualified powder is discharged by the finished product discharging opening through classification and is collected.

3, this machine of beneficial effect is compared with China present employed Raymond mill, and every performance indications are leading, and particle size range is ground carefullyyer than common Raymond mill, is fit to the processing superfine powder.Concrete advantage is: the 1. radian of track unique design, and can make grinding machine when driven by motor is rotated, produce centrifugal force, make the suspension of ring emery wheel, press weares and teares thereby reduce plate rail; 2. the tight engagement of track radian and wheel radian makes accumulation material stock in the groove, realizes pulverizing; 3. shellring millrind structure can effectively improve fineness and the output of pulverizing the material thing; 4. the ring millrind of different angles, i.e. the storing of staggering of upper two layers and the 3rd layer can prevent effectively that coarse fodder from escaping, and improves and pulverizes probability.

(4), description of drawings

The utility model can illustrate in conjunction with the embodiments.Figure of description is an embodiment of the present utility model.Wherein Fig. 1 is a front view; Fig. 2 is a vertical view, and as seen its ring millrind 2 is three layers and upper two layers and following one deck staggered positions situation.1 is the auxilliary axle of ring mill among the figure; 2 are the ring millrind; 3 are ring emery wheel; 4 are ring mill track; 5 is the rail support ring; 6 for breaing up rib; 7 is the main frame lower house; 8 is belt pulley; 9 is main shaft.

(5), the specific embodiment

The specific embodiment of the present utility model is shown in Figure of description 1,2, and it is made up of the grader on top, the ring mill main frame of bottom.Ring mill main frame mainly comprises parts such as the auxilliary axle 1 of ring mill, ring millrind 2, ring emery wheel 3, ring mill track 4, rail support ring 5; Its ring emery wheel 3 and the ring mill track 4 that cooperates with it are the arcuate structure of tight engagement; Its ring millrind 2 is three layers and upper two layers and following one deck staggered positions.By main driven by motor ring millrind rotation, make ring emery wheel produce centrifugal force, thereby being encircled the centrifugal force of emery wheel, powder rolls realization pulverizing in rail groove.

Claims (2)

1. the broken grader of mechanical type ring abrasive dust is made up of the grader on top and the ring mill main frame of bottom, it is characterized in that its ring emery wheel (3) and the ring mill track (4) that cooperates with it are the arcuate structure of tight engagement.

2. the broken grader of mechanical type ring abrasive dust according to claim 1 is characterized in that, its ring millrind (2) is three layers and upper two layers and following one deck staggered positions.
