Bucket elevator maintenance

In the use of the course, bucket promotion drive failure are the following rare circumstances:


Bucket promotion cause a malfunction. Hopper with skid


(1) Bucket promotion machine is the application of hopper bands and head mill wheel friction torque between the drive shaft for elevator materials, unpredictable enough hopper

belt tension will lead to the hopper with skid. At this time, manufacturers should immediately stop rod mill machine, conditioning installation to tighten the hopper belt

tensioner. If you can not make the hopper belt tensioner complete installation tension, tension mounted explain the trip was too short, we should start a new conditioning.


Accurate approach is: to unlock the hopper with joints, the tension on the bottom wheel mounted to the highest position in the hopper into the machine head with the promotion,

through the fire Jaw Crusher Price wheel and the end of round, and both converge Well, the hopper with the tension in the situation without tension. Then install the full

tensioning the tensioning. At this point the conditioning tensioning screw skate roller conveyormounting tension stroke has not been applied not less than 50% of the whole trip.


(2) promotion machine overload promotion machine overloaded, drag torque increases, leading to the hopper with skid. You should reduce the amount of material fed, and trying to

feed an average. If you reduce the feed rate, still not improved skid Sand manufacturers, it is possible to sit inside the material accumulation is machine hopper is too much or

mentor thing stuck, stop the review, eliminate the fault.Telescopic conveyor


(3) first round shafts and hopper band looks too moist sly wheel shaft and hopper band appearance Henan broken jaw too lubrication, reduces friction between the two, resulting

in the hopper with skid. At this time, the shaft and the outer coating hopper with the inner layer of plastic, in order to increase friction.


(4) the end of the first round and the first round of wheel bearing rotation ineffective and bottom wheel bearing rotation ineffective, moment of resistance increases, causing

the hopper with skid. Then washable refueling or change bearings.


Bucket promotion malfunction causes two. Hopper with a deviation


(A) the end of the first round and the first round wheel shaft is improperly installed and the bottom wheel drive shaft installed incorrectly important statement today following

aspects: First, the end of the first round and round in the same vertical solid shaft inside without parallel; Second two shafts are mounted in a horizontal position is not in

the same vertical internal perspective; third two parallel shafts, and not in the same vertical level within the three-dimensional. At this time, the hopper with a deviation

could easily cause a crash and barrel hopper, hopper bands tear. Should be immediately shut down, eliminate the fault. Do head end of round Henan mill wheel and drive shaft

mounted within the same vertical stereo, and in horizontal position, the whole central line height 1000mm vertical deflection does not exceed 2mm, the accumulation of bias does

not exceed 8mm.


(2) hopper with hopper with connector fitting errors is not exactly refer to the hopper with the combined hopper band edge along the line is not always the same. Tasks, while

tight side of the hopper with loose, so that the hopper with the tight side lateral move, attack deviation, forming hopper containing material is not sufficient, discharge is

not complete, back to the material increases, the consumption rate landing, formed when material hopper with a card edge, torn. At this time should be shut down, modify joints

and connected.


Bucket promotion malfunction causes 3. Excessive production of gravel back to the material equipment, spiral classifier, impact crusher, cement mill, crusher and other equipment

has passed ISO9001 international quality system certification. Welcome to buy!


Promotion machine back to the material refers to the material in the unloading position not fully discharged outside the machine, while the material back to the local promotion

of the scene inside the base machine. In the promotion work, if promotion machine back to the material too, is bound to land consumption effect, increasing energy consumption

and material breakage. Back to the material causes the formation of more than the following:


(1) hopper run too fast promotion opportunities promoted different materials, hopper running speed is different: individual promotion boring powder and pellets, the rate of

about 1 ~ 2m ÷ s; promotion of bulk materials, the speed to 0. 4 ~ 0. 6m ÷ s; promotion moist powder and pellets, the speed is 0. 6 ~ 0. 8m ÷ s. Speed ​​is too large, early

discharge, the formation of recycled material. At this promotion should be based on the material, the proper landing speed of the hopper to prevent back feed.


(2) discharge outlet nose tongue plate mounting unfit, tongue plate is too far away from the hopper discharge status, will form back to the material. Should be the swap tongue

position, to prevent back feed.
