Bucket Elevator For Limestone
Dear Shri Shrinivas Bartakke,
The bucket elevator is handling 75 mm size limetsone. So firstly the bucket size should be suitable for this lump size. Preferably bucket speed should be low. Also lumpy limestone digging (scooping) resistance would be more and so bucket mounted on chain will be able to deal with the forces better. Positive discharge has low speed (around 0.6 mps) i.e. 120 fpm, the continuous type bucket elevator has also low speed about 0.6 mps and super capacity type of elevator (as named by US practice) has about 0.5 mps (100 fpm) speed. So one can have a choice about the type of bucket elevator with respect to capacity mtph. Refer the manufacturer of elevators with the specific application data to get the recommendation / quotation.

Re: Bucket Elevator For Limestone
Thanks you very much Sir for your reply.
We have also received the offers from the different suppliers of the Bucket Elevators, most of which have preferred with the positive discharge bucket Elevator as mentioned by you in the above reply.
Hope to see you again.

Dsi Snake Sandwich High Angle Conveyor
Dear Shri Shrinivas Bartakker,
Have you considered the DSI Snake Sandwich High Angle Conveyor instead of the bucket elevator?
The DSI Snake has many advantages including:
- Unlimited conveying capacity
- A system suitable for the most rugged mine applications, yet gentle on sensitive and friable materials.
- High availability and low operating and maintenance costs.
- Smooth surfaced belts allow continuous belt cleaning by scrapers and plows. This also facilitates intermediate material discharge by belt plows, as appropriate, before and/or beyond the sandwiched part of the Snake profile.
- All conventional conveyor hardware insures economy and fast delivery of replacement parts.
Please email me at aduncan@dossantosintl.com so we can provide you further information.

Bucket Elevator For Limestone
As you might guess I agree with Amy. A Dos Santos sandwich belt high angle conveyor is a better solution. If you insist on a bucket elevator then I would recommend positive discharge or continuous discharge and this will limit you to a very slow elevator speed. The slow speed will be to ensure maximum discharge/minimum carry-back and minimum material damage. This does not undo the damage of the confronting bucket lips digging in the boot. Even in the case of a continuous design, where the material transfer should be directly onto the buckets substantial digging still occurs as the clean transfer is impossible to achieve.
Centrifugal type discharge will be mayhem with course limestone and the wear and tear will eat your lunch.

Bucket Elevator for Limestone
Dear All,
Greetings
In one of the project, we need to convey lime stone with the particle size of -75 mm (where 75 mm is the maximum lump size and the lump percentage is unknown)
Due to the space constraint, we have to choose Bucket Elevator to conveyor the lime stone.
Kindly let us know weather Bucket Elevator is suitable for the Lime stone with the above given size. If yes, which type of bucket elevator will be advisable. (i.e Positive discharge, Continuous or Centrifugal)
Thanks in advance for replying to the above subject. ■
