But how to make charcoal briquette from agricultural waste?

What machines can be used in making agricultural waste charcoal briquette?

Besides suitable material selection, it is also necessary to buy professional equipment for agricultural waste biochar briquette plant. Because it is the secret of finishing charcoal briquette from agricultural waste smoothly and quickly. But what machine is needed for agricultural waste charcoal briquette production? In general, you need the following five charcoal briquette processing machines.

Hammer mill

If you want to achieve the continuous production for agricultural waste biochar briquette, continuous carbonization machine is more suitable for you. But the feeding material of this machine is different according to agricultural waste. Such as wood chips and sawdust are usually ideal for particles smaller than 5 mm. Then straw & plant residues are usually no longer than 20-50 mm and no wider or thicker than 10 mm. Finally, branches and wood chips are usually no larger than 30-50 mm. For this, hammer mill is necessary.

According to the above mention, the rotary carbonization furnace is suitable for charring the agricultural waste which are in small pieces. Though the carbonization rotary kiln has the function of drying, we don’t suggest carbonizing the wet materials directly, it will affect the carbonizing efficiency and charcoal quality. So it is better that make sure the moisture of materials is less than 30%.

Charcoal wheel grinder

Wheel grinding mixer consists of a pair of rollers and a pair of shoveling plates. Charcoal particles are grinding into powder by the roller. And it can blend the charcoal powder with water and a binder evenly. It is ideal equipment for producing biochar briquette.

There are four types of charcoal briquettes making machines for your choice. Including charcoal extruder machine, biochar ball press equipment, hookah press machine and rotary charcoal tablet press. So you can choose a suitable one for agricultural waste charcoal briquette making.

What is the cost of agricultural waste charcoal briquette making line?

For a complete charcoal briquette production line for making agricultural waste into biochar briquette, the cost is closely related to the equipment design. There are some examples for your reference.

500-1000 kg/h agricultural waste charcoal briquette making system cost

In general, you need to prepare $61,000 – $150,000 for a hookah press line for your 500-1000 kg/h agricultural waste charcoal briquette plant. Because it has small capacity and detailed processes. Its processes usually contains hammer mill, continuous carbonization machine, charcoal wheel grinder, double shaft horizontal mixer, hookah press equipment.

1-10 t/h biochar extruding system from agricultural waste investment

As for buy agricultural waste charcoal extruding system, it needs $85,000 – $335,000. Generally, the layout of an 1-5 t/h agricultural waste charcoal briquette factory is loader type feeder, hammer mill, continuous carbonization machine, charcoal wheel grinder, double shaft mixer and rotary charcoal tablet press. But for 5-10 t/h output, it is advisable to replace charcoal extruder machine.

10-30 t/h agricultural waste charcoal ball press plant budget

How about the 10-30 t/h charcoal ball press plant? How much dose the agricultural waste charcoal briquette production line cost? It needs $310,000 – $900,000. Because it has a large capacity, which customer needs enough budget. Including loader type feeder, hammer mill, continuous carbonization machine, charcoal wheel grinder, double shaft mixer and charcoal ball press equipment.
