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.
