It is very common to use an explosion-proof motors,motors’ explosive class is EXDIIBT4.In such case,we will design and make a backstop device to prevent buckets go in the wrong direction if motor is stopped all of sudden.
Here is an example technical data form :
1 | Bucket width | 160mm | Photo | 
|
2 | Hoist height | 4900mm | ||
3 | Conveying capacity | 1.6m3/hour | ||
4 | Speed of elevator | 10rpm | ||
5 | Motor power | 2.2KW | ||
6 | Gearbox model | R97 | ||
7 | Usually the bucket width is 100mm,130mm,160mm,200mm,250mm,315mm,500mm,630mm |
The bucket elevator’s shell is made up of head shell,middle shell and tail shell. It requires high suitability between shell’s flanges.So these flanges will be made through precision work.
Sometimes there exist pressue inside bucket elevator .We will make a pressure test before delivery,and to ensure this bucket elevator can work under required pressure.
