Mainly Factors about Model Selection of Bucket Elevator

As common used lifting equipment, selection of bucket elevator is effected by many factors, wrong model will give customers endless troubles. Generally, model selection of bucket elevator depends on the following factors.
1. Material shape: powder, granular or small lump material.
2. Physical property: adsorbability or viscosity, and moisture content.
3. Proportion of material: common bucket elevator parameters are designed and calculated according to the materials which mass density under 1.6. While large proportion of materials are according to tensile strength of traction and drive part.
4. Unit conveying capacity:
Generally speaking, shape of material directly determines the discharging method. It is common practice that powder materials use centrifugal discharge and gravity discharge for lump materials. In addition, different charge method determines the different type of bucket, centrifugal discharge always use shallow or arc bucket, while deep bucket for gravity discharge. The unit conveying capacity of bucket elevator is different as its different bucket type. The conveying capacity of bucket elevator is a comprehensive parameter that depends on bucket type, speed, proportion of material, property of material and number of bucket. Selection process is as follows: proportion of material, property of material, discharging method, bucket type, conveying capacity and the model.

How to Install the Asbestos Tape in the Bucket Elevator?

How to Install the Asbestos Tape in the Bucket Elevator?

In the process of the installation of the bucket elevator,in order to prevent the leakage of dust, pollute the environment,our engineer always using the asbestos tape in the bucket elevator.Here we will introduce the detailed information as follows.

Why the asbestos tape has such good sealing?That's mostly because the asbestos tape is woven with high quality stone cotton yarn.Asbestos tape is suitable for various thermal equipment for heat preservation, heat insulation material or processed into other asbestos products.

A good sealing plays an important role in the installation quality of the bucket elevator.  Asbestos Tape is the best choice of sealing material, which is installed on the casing flange joints.What you should pay attention is that you should put the asbestos tape into the interface before connecting flange, and then connecting the bolts.

Four Methods to Solve Uneven Rotating Speed of Bucket Elevator Problem

1. Base frame blockage
The reason is feeding prior to start-up, the bucket belt lacks of tension which will cause belt skid, or the inflow rate of feeding is greater than the conveying capacity (including excessive of feeding back), as well as bulk materials enter into the base frame. The methods to eliminate the problem is to shut down the machine at once, close the feeding chute, open the base frame gate plate , clear the clogged material, and start up the machine in accordance with procedures. And also adjust the tension device in order to strengthen the clean up speed of anterior materials.
2. Conveying capacity reduces
The reason is due to the skid of the drive belt or lifting belt, insufficient rotating speed of electrical motor, uneven feeding, serious feeding back, unreasonable selection of bucket design. The methods to eliminate the problem is to adjust the tension device, check electrical motor, eliminate the fault, feed evenly, identify the cause for promptly discharge of material, and select bucket design reasonably.

3. Excessive of material returning back
The reason is the linear speed of belt elevator too fast or too slow, improper design or size of drive head, material discharging in the outlet is not smooth. The methods to eliminate the problem is to adjust the rotating speed of bearing, modify the external dimensions of drive head or adjust the drip plate at the bucket gap, and unblock the outlet.
4. Casing wears seriously and large power consumption
The reason is the installation of bearing tilts, dust deposition on bearing, poor lubrication, bearing failure or elevator belt is too tight, excessive of material returning back, blockage of base frame. The methods to eliminate the problem is to readjust, clean or change the lubricating oil, replace the bearing and adjust it properly. Identify the cause for promptly discharge of material, and clear the clogged materials.
