The present invention relates to a kind of crushing devices, more particularly, to a kind of screening type grinding of large reduction ratio support roller carrying roller supportMachine.
Background technique
Traditional broken scratch system is by primary crushing, second-time breakage, flour mill, screening machine, conveying equipment, dust collection deviceDeng composition, entire process equipment is more, and environment fugitive dust is big, and operation and maintenance are difficult, and process flow is too long to cause capital construction investment very big.
Current broken milling production technology: supplied materials is crushed to by alumina crust block using jaw crusher to be less than200mm is delivered to surge bunker by belt conveyor, then by vibrating feed to meet the pan feeding requirement of subsequent screening type flour millMachine, which is delivered to the material after screening type flour mill, (or autogenous tumbling mill, counterattack broken) crushing and grinding and is delivered to bucket type by flat belt again, to be mentionedThe machine of liter, bucket elevator are conveyed to screening machine, and the material of sifted qualification off the net, to finished bin, is sieved by chute or Belt ConveyingUnderproof material is crushed by belt return again again on extension set sieve, is had the following problems in whole system；
1. since the pan feeding of existing screening grinding machine is to feed screening type flour mill by the hollow shaft of grinding machine bearing, by screening type powderThe limitation material size of grinding machine bearing diameter is less than 200mm, increases hollow shaft diameter if it is material size is improved, can be very bigIncrease the difficulty of processing and manufacturing cost of screening type flour mill.
2. jaw crusher is difficult to effectively seal, dust collection effect is poor, easily blocks, expects clearly difficult in maintenance；
3. equipment is more, space occupied is big, cause equipment and capital expenditure larger.
4. process route is long, dust collection effect is bad, and environmental pollution is big, operation and maintenance higher cost.
Summary of the invention

The deficiency of the present invention to solve above-mentioned technical problem, used technical solution is:
A kind of screening type flour mill of large reduction ratio support roller carrying roller support, the cylinder of several hollow holes is offered including one thereonBody, the end of cylinder are equipped with aside-liner, and the shell liner of several interval cooperations is equipped on cylinder lateral wall and promotes liner plate, cylinderThe outer cup of body is equipped with shell, and cylinder is sealed in a closed cavity, is connected on wherein one end of cylinder axial direction by shellHollow shaft is fed, charging hollow shaft is connected to through shell with cylinder lumen, and it is hollow that discharging is connected on the other end of cylinder axial directionAxis, discharging hollow shaft are connected to through shell with cylinder lumen, are provided with reversion row in cylinder on one end of discharging hollow shaftExpect that device, reversion discharge device are connected to discharging hollow shaft, charging hollow shaft, cylinder, shell and discharging hollow shaft cooperateRotating part is formed, rotating part is rotatably supported in support roller group, feeds the spiral shell for being provided in hollow shaft and material being imported to cylinder lumenStructure is revolved, is provided in the hollow shaft that discharges by the helical structure of material export cylinder lumen, rotating part is driven by driving mechanismRotation, material are admitted in cylinder from charging hollow shaft, and material is mentioned in the case where promoting liner plate effect in rotating part rotation processIt rises and casts and be crushed on cylinder inboard wall to realize, the housing bottom is provided with splicing chute.
It is connected with dust arrester installation on the shell and collects dust in order to form negative pressure in cylinder lumen.
The charging hollow shaft is far from being provided with feed hopper on one end of cylinder, the diameter etc. of the charging hollow shaftIn the 1/3~1 of the diameter of cylinder.
Offer sieve pore on the shell liner, the area of the sieve pore exit side is greater than the area of feed side and mutualDraft taper hole is cooperatively formed, to avoid feed blocking sieve pore.
The driving mechanism includes driving motor, chain, drive sprocket and driven sprocket, and driven sprocket is fixed on dischargingDrive sprocket is connected on the output end of driving motor outside hollow shaft, and chain is set on drive sprocket and driven sprocket and is formedChain wheel drive mechanism.
The rotating part is connected in support roller group by wheel belt, and wheel belt is fixed on the outer wall of rotating part.
The support roller group is supported on mounting plane by adjustable base.The beneficial effects of the present invention are: the application collectsSecond-time breakage, screening, removal of impurities is multi-functional is integrated, and the broken milling process of tradition can be reduced to support roller carrying roller screening type grindingMachine --- conveying --- finished bin+dust collecting system.Simplification of flowsheet reduces equipment, capital expenditure, reduces operation and equipmentMaintenance cost.
