Description
Technical field
The invention belongs to a kind of raw material processing equipment, specifically, more particularly to a kind of powder cycle crushing and classification production
Line.
Background technology
Ball mill is the key equipment that material is broken and then crushes, it is widely used in cement, silicate system
Product, the production industries such as New Building Materials, refractory material, chemical fertilizer, black and non-ferrous metal ore and glass ceramics, to various mines
Stone and other grindability materials carry out dry type or wet type grinding.Ball mill is suitable for the various ores of grinding and other materials, wide
It is general to be used for ore dressing, the industries such as building materials and chemical industry.It is existing using ball mill carry out powder production technique be:Usually first a certain amount of
Coarse fodder placement be ground in the ball mill, after the completion of to be ground, the powder after grinding is carried in grader and is divided
Grade screening, obtained qualified products carry out packaging or next process, and underproof product will be put together, after a certain amount of
Concentration send into ball mill the screening for carrying out ball milling again, and again passing by grader.Current powder crushing and classification production line
It has the following defects:(1) conveying pipeline bend air-flow and product directly pass through, larger to the abrasion of channel bend easy-wearing surface, lead
Cause product iron-holder high, high labor cost is replaced and expends the time;(2) abrasion of grader page wheel bottom surface is big, and product iron-holder is high,
Repair and replacement are difficult, time and effort consuming;(3) feed back uses discharger feed back, and discharger material mouth poor sealing, abrasion is big, causes
Product iron-holder is high, and difficulty is replaced in repair, and time and effort consuming is of high cost.
Invention content
It is an object of the present invention to provide a kind of powders to recycle crushing and classification production line, to overcome powder crushing point in the prior art
Grade production line pipeline elbow, grader page wheel and discharger material mouth wear larger, the high defect of product iron-holder.
Realization that the present invention adopts the following technical solutions:
Powder of the present invention recycles crushing and classification production line, including ball mill, conveyance conduit, grader and feed back dress
It sets, the ball mill discharging mouth connects grader with channel bend by conveyance conduit, and the grader coarse fodder outlet connects back to
Expect device, the feeding back device includes feed back pipeline, and the feed back on the feed back pipeline exports last point and is covered with fixed envelope
Closure plate, another part are covered with movable plugging plate, and the activity plugging plate is connected through the hinge on fixed plugging plate, and only
It can be to activity on the outside of feed back pipe outlet.
The channel bend is the box like structure that section is more than conveyance conduit section.
The grader page wheel bottom surface rotation backplate uses polyurethane material.
Compared with prior art, the beneficial effects of the invention are as follows:
(1) it is more than the box like structure of pipeline section at conveying pipeline bend using section, there are one rotations after air-flow enters
Effect, each surface wear is average;
(2) rotation backplate in grader page wheel bottom surface uses polyurethane material, wears small, handling ease;
(3) feeding back device is quick on the draw, and is not easy to plug pipeline, makes simply, abrasion is small.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention;
Fig. 2 is the structural schematic diagram of the feed back outlet of the present invention;
Fig. 3 is the structural schematic diagram of the channel bend of the present invention;
Fig. 4 is the page wheel of the present invention and rotates the structural schematic diagram of backplate;
In figure:1, ball mill;2, conveyance conduit;3, channel bend;4, grader;5, feed back pipeline;6, feed back exports;7,
Fixed plugging plate;8, hinge;9, movable plugging plate;10, page wheel;11, backplate is rotated.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, powder of the present invention recycles crushing and classification production line, including ball mill 1, conveyance conduit
2, the discharge port of grader 4 and feeding back device, the ball mill 1 connects grader 4, institute by conveyance conduit 2 and channel bend 3
The coarse fodder outlet connection feeding back device of grader 4 is stated, the feeding back device is arranged above 1 feed inlet of ball mill, the feed back
Device includes feed back pipeline 5, and the feed back of the feed back pipeline 5 exports 6 last points and is covered with fixed plugging plate 7, another part
It is covered with movable plugging plate 9, the activity plugging plate 9 is connected to by hinge 8 on fixed plugging plate 7, and can only be to feed back
The outlet of pipeline 5 outside activity.
As shown in figure 3, the channel bend 3 is the box like structure that section is more than 2 section of conveyance conduit, air-flow enters pipeline
There are one the effect of slew buffer behind 3 box like structure inside of elbow, 3 each surface wear of channel bend is average.
As shown in figure 4,10 bottom surface of the page wheel rotation backplate 11 of the grader 4 is using small, handling ease the poly- ammonia of abrasion
Ester material.
The present invention operation principle be:Ball mill 1 is added from feed inlet in raw material, it is negative in the air-introduced machine of connection grader 4
Under pressure effect, the powder after ball milling enters grader 4 from 1 discharge port of ball mill through conveyance conduit 2 and channel bend 3, through dividing
After grade machine 4 sieves, granularity underproof powder is discharged into feed back pipeline 5 by grader 4 when working, while under air-introduced machine effect
Negative pressure is formed in feed back pipeline 5, movable plugging plate 9 is close to the feed back outlet 6 of feed back pipeline 5, feed back pipe under the action of negative pressure
Road 5 exports whole closings, and when the underproof powder of granularity runs up to certain amount, the vacuum force of air-introduced machine is less than powder
Gravity, movable plugging plate 9 are opened outward, and powder falls into 1 feed inlet of ball mill and carries out ball milling again, then recycles above-mentioned work
Process, when the vacuum force of air-introduced machine is more than the gravity of powder, movable plugging plate 9 is closed, and powder stops falling, this structure is kept away
Exempt from powder and feed back outlet 6 is persistently in friction contact state, significantly reduces the abrasion of feed back outlet 6.
