Coal Crusher

More information is required.

What type of crusher classifier are you considering?

Is it a ball mill, a tyre and table type or a set of reciprocating jaws?

Is the coal being crushed to a fine or a coarse consistency? The finer you wish to crush to the greater power requirements. It may also require a reduction in the feed rate if it is to fine.

The type of coal is also critical. The higher the ash content the lower the coefficient of friction. If the coal is washed then you may have additional requirements for clearing blockages in your feed system.

It is the classic how long is a piece of string?

We are basically looking at a coal lump breaker fitted to the rear of a discharge conveyor on a coal cutting machine. To transport the coal on it next journey out of the mine, it must be sized to 200mm maximum "lumps"

Coal would typically be up to 30MPa.

I realise there are a few f"udge factors" to throw in but am looking for a feel of how much power would be consummed.

I think you might be look at this project from the wrong perspective. It seams like you might be stating conveyor speed rates and quality characteristics of the end product. You might be focusing your attentions more on what you want to do than how much of it you need to do. I think one question that might be inportant is what is the size (capacity) of the lump breaker. How much lumps (tons, kilogram, or what ever weight you measure it in) you want to have broken is largely depend on size of the equipment.

There are many lump breakers available. Use "lump breaker" as a product search (you might have to use other words also I am just guessing) word to find a company that can help you specifiy what type of breaker, size and power requirements you need. Once you find you power requirements then you have an answer to your energy requirements question.

I would really ask your project manager if he/she knows what they are doing or if they have any experience in this application. If they don't, I hope you have a lot of money. I think you are going to be using a lot of it.

Talk to someone who has done this type of work. It might cost you big time dollars, but it could save you that much in mistakes (and time to correct them) if you build/buy the wrong component. Mistakes can take a toll on our projects and our ego. I am saying this because I screw up all the time.

Good luck.
