Removing correct bearing shaker

In the course of using the shaker , we always because of this or that reason , you need to remove vibrating screen bearings, false

Such as vibrating screen bearings demolition is incorrect, could cause damage within the bearing , contaminants may enter the shaft

Order . So on the vibrating screen bearings stone feeding machine demolition process, we should pay attention to the following three points :
( 1 ) shaker tapered bore bearing removal removal more compact adapter sleeve bearings, fastening on the bearing stopper

Supporting the inner ring, the nut back several times, using the pads with a hammer and beat demolished ;
( 2 ) shaker cylindrical bore bearing removal vibrating screen manufacturers by pressure mechanical pull , so that the inner ring to withstand pulling force , is the easiest inner demolition

Method ;
( 3 ) Removal of external shaker
     Removing the interference fit of the outer ring , the circumference of the housing in advance several outer extrusion screw is provided with a screw , while the

Tighten the screw equal , while removal. These screw holes on the usual blind plug , shaker tapered roller bearings and other sub-

From the type of bearing , the housing block set shoulders several incisions , the use of pads, with presses gently tapping the demolition or removal

Vibrating sieve and screen box frame broken explore

In the process of using vibrating screen , vibrating sieve sieve sieve frame and box beams fracture is a relatively common problem , then what
What causes vibrating sieve sieve sieve frame and box beams break it ? We vibrating sieve sieve boxes and boxes of broken bits
Set to start, will cause analysis for the following aspects:
First , vibration sieve vibrator on both sides of the vertical support plate is too short causes. When the time is too short mining screen riser , vibrator screen frame
Force above the surface will be more concentrated , resulting in vibration sieve and screen box frame breakage , for this situation , we should
Vibration sieve riser extended in order to play to improve the screen frame often fracture failures.
Second , vibration sieve sieve box frame with broken crusher machine plates with thickness vibrating sieve box there is a certain relationship, if vibrating sieve box
Thick enough , it is most likely caused by vibrating sieve and screen box frame broken, so for this situation, we can change the
As with thick high quality steel sieve shaker box .
Third , vibration sieve shaker and screen box connecting bolts discontinuity , causing vibration sieve sieve box frame with broken needles
On this situation, we should adjust the vibration sieve shaker position, changing the force , so that even by force .
Fourth, selection and beams shaker force strength is not enough.
Fifth , each shaker inconsistent internal stress between the beams .
These five points are based on vibrating sieve sieve box frame and determine the location of fracture vibration sieve boxes, screen frame crossbeam rupture causes.

Bucket elevator hopper belt slippage

( 1 ) bucket machine is to use the hopper with the first round of the friction torque between the drive shaft for elevator materials , unpredictable enough hopper belt tension

will cause the hopper with skid. At this time , you should immediately shut down, adjust the belt tensioning device to tighten the hopper . If you can not make the hopper belt

tensioning device is fully tensioned , said

Ming tensioning device trip is too coal production line short, should be re- adjusted .
The correct solution is : untie bucket elevator hopper with coupling to the bottom tensioning device on the wheel adjusted to the highest position , the hopper with bucket

elevator into the hoist head through the first round and bottom round , and both connected, the hopper with bucket elevator in the tensioner without sheets

Tight state. Then the tensioning stone feeding machine device is fully tensioned. At this point tensioning device untapped tension adjustment screw stroke of not less than 50% of the whole trip .
( 2 ) bucket elevator overload , resistance torque increases, resulting in the hopper with skid. You should reduce the amount of material fed and seeks uniform feeding . If you

reduce the feed rate , still not improve skid, sit inside the machine may be too much or material accumulation mentor material hopper are stuck , you should stop to check

, Troubleshooting.
( 3 ) bucket elevator hopper nose wheel shaft and the inner surface is too smooth head with round shafts and hopper band surface is too smooth , so that the friction between

them decreases, resulting in the hopper with skid. At this time, the hopper with the shaft and the inner surface coated with a layer of adhesive to increase the friction.
( 4 ) bucket elevator nose wheel and wheel bearing rotation not working head end and a bottom wheel bearing wheel rotation ineffective, moment of resistance increases, causing

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

Vibration platform should be noted that in the course of events

Vibration platform in the application process tap major role to play in the long-term use should be careful to check the vibration motor mounting screws are loose in the long

process of using the vibrating Circular vibrating screen body is broken , in order to avoid breaking the vibrating body , adopted a new kind of riveting , long look at the

The use of practices achieved certain results
 Vibration sieve in the filtration Dry vibrating screen industry needs to pay attention
Vibration sieve in the filtration industry is also widely used , but the actual operation, there are many problems , and sometimes the material according to the filter mesh

sieve has a great relationship, and not a one-time feeding too much , it is prone to breakage sieve , affect the production , the most effective method is: 1 in cast

Delivery boring case, the power to open , screen machine operation , 2: the case of delivery of materials to be gradual.

Vibration sieve matters noted during transport

Vibration sieve again before shipment need to do is
1: Check the accessories are complete
2 : Check the screws are sand vibrating screen imprisoned
3: Check the transport support is secured , especially this one , because a lot of time in transit , since transportation support will cause damage during transport, sport

springs with crane swinging back and stone screening machine forth , there will be a spring crooked , broken, lost , etc. phenomenon . Affect the normal use
4: Upon arrival, the first look at the transport support is intact. Then twist off the screw , remove the support, check the parts , springs , power use

Vibration motor power calculation

Vibration motor power calculation :
Motor power , should be based on the required power production machinery to choose, as the motor at nominal load . Selection coal vibrating screen should pay attention to the following points:
① If the motor power selected too small . There will be " small horse cart " phenomenon , resulting in long-term motor overload . Insulate due to heat damage. Even the motor is

burned.
② If the motor power selected too China Vibrating Screen large . There will be " big horse car " phenomenon. The output mechanical power can not be fully utilized , power factor and efficiency is not

high , not only for users and grid disadvantage. But can also cause energy waste .
To correctly select the motor power , you must go through the following calculation or comparison:
P = F * V / 1000 (P = computing power KW, F = desired tension N, working machine line speed M / S)
For constant load continuous work, can be calculated as the required motor power :
P1 (kw): P = P/n1n2
Where n1 is the production efficiency of the machine ; n2 efficiency of the motor , the transmission efficiency .
Power obtained by the above formula P1, is not necessarily the same power with the product . Therefore . The rated power of the motor selected to be equal to or slightly greater

than the calculated power .
In addition . The most commonly used is the analogy to select the motor power . The so-called analogy . With similar production machinery is used to compare the motor power .
Specifically: the understanding of the unit or other units of similar nearby production machinery using multiple high-power motor , and then use the power of the motor is

similar to trial . The purpose is to verify that the selected test motor and production machinery match.
