Weighing of bagasse with a builtin beltweigher is possible. Depending on the

parameters of the installation, can be made a decision. For a first overview,

we need a drawing of the belt and the following information:

belt width and trough-form p.e. 20°, 3-fold

belt inclination

distance center axis

belt speed in m/s

nominal capacity in t/h,

weigh system works proper in a range 1:5

Best possible accuracy in the range of +/- 1 %.

best regards

It is possible , but difficult, to weigh bagasse on a conveyor belt, but

there have to be special cinsiderations as to the speed, width, troughing of

the belt in order to achieve an acceptable specific loading of the belt such

as to enable reasonable weighing to be done.

I have experience of such an application in the Caribbean. As regards the

handling aspects, these too need to be carefully considered in order to match

the weighing requirements. A company such as Fletchet & Stewart should be

approached for that question.

Thayer Scale have several different design belt scales that can be retrofitted into existing belt conveyor systems.

These belt scales can weigh regardless of intermittent flow. If you would

like send us information on your conveyors and we can take a look at it.

As for discharging Bagasse from silos, Vibra Screw has been successful in

discharging this material using its Bin Activator.

There a couple of possibilities here.



1. Inline weighing by putting loadcells under a section of the conveyor will give a real overall weight to an accuracy of about 3%.



2. Placing a receivable hopper on loadcells will give accurate weight to 0.1%. To extract the material from the hopper you will probably need to use a screw feeder and possibly vibrator/agitator on the hopper. We know companies in Australia who have experience in this type of installation.



Hope this helps.

We would like to visit the plant and study the feasibility to offer a suitable weighing system.We believe we can do it.

We work in the weighing area in the sugar industry though not

specifically for bagasse weighing but we can offer a suitable system.

Thanks and warm regards,

Dear Sir,

We propose you to use a Laser Scanner which is installed over the conveyor belt, measuring the exact profile of transported Bagasse material in very short time cycles (about 75 readings per second). In this way you will get the exact Volume Stream continuous (e.g. as cubic-metres per hour). If we take a unalterable density of Bargasse as a point of departure then we will get the exact tonnage of Bargasse also (e.g. in kilograms per second). Of course you need the scanner and an evaluation unit and the suitable software also.

If there is your interest or any further information you would like to have please write me by fax or email.

Yours sincerely,

hi,

i have been to this problem of weighing bagasse online too. in my opinion, the solution to the problem is to measure the RPM of the rotory bagasse feeders. if we know the RPM of the bogasse feeders, and as the magnitude of bogasse being fed to the combustion chamber of the Bogasse Boiler is same (considering bagasse feeder as positive displacement type), if we multiply the amount of bogasse fed by the feeder in one rotation with the RPM of rotary feeder, we can get the total amount of bogasse in kgs/Hr.

Assumptions:

1. the shoot above the rotatry feeder should be filled with bogasse completely.

2. the moisture contents of the bogasse should be considered same

3. the calorific value of the bogasse is kept constant( to calculate the total heat input from bogasse)

thanking you,
