Author : Jordan Last Updated : Aug 31, 2019

What is charcoal briquette

The charcoal briquette refers to the charcoal powder pressed by the briquette machines. In addition to the ball shape, it can also be produced various shapes such as perfect round shape, bread type, strip type, egg type, square type, elliptical type shape, and the like.

It is widely used in many fields such as metallurgy, chemical industry, refractory materials, energy, animal husbandry, transportation, power plants, agriculture, industry, barbecue, and heating.

Why charcoal briquette

Charcoal briquettes are widely used in barbecues, fuels, etc. around the world. Studies have shown that in charcoal production enterprises, fine waste materials account for 10% to 15% of available charcoal. Thus, a large survey was conducted on the charcoal briquette machine to avoid resources wasting.

And for other low-density woods and bulk materials, such as charred coconut shells, we also make these charcoal into briquette to improve the quality of charcoal for further use.

Source of charcoal briquette

Charcoal briquette, also known as mechanism charcoal, artificial charcoal, and smokeless clean charcoal, are carbonaceous spheres extruded from charcoal powder. Its raw materials sources are various, like crop straw husk, peanut shell, cotton shell, corn cob, corn stalk, high stalk and other forestry residues can be used for briquettes.

The charcoal briquette has features of high density, high calorific value, being smokeless, odorless, non-polluting, non-explosive and flammable. It is an internationally recognized green environmental protection product.

The usage of charcoal briquette

Charcoal briquette are an ideal fuel because they produce a hot, long lasting, virtually smoke-free fire. Combined with other adhesives, the powder can be pressed a uniform sphere or block, often used for outdoor cooking.

Charcoal is produced by burning carbon-rich materials such as wood in a low oxygen atmosphere. This process drives off the moisture and volatile gases present in the original fuel. The resulting charred material not only burns longer, is more stable, but is lighter than the entire wood (one-fifth to one-third of the original weight).

The production of charcoal briquette is inseparable from the merits of the briquetting machine. And a large number of briquettes are inseparable from the large briquette machine. So, what is a large charcoal briquetting machine?

Large charcoal briquette machine

What is large briquette machine

The large briquette machine is mainly used for pressing powder materials that are difficult to form. It is characterized by large molding pressure, adjustable number of revolutions of the main engine, and a screw feeding device.

Through the belt, it is transmitted to the reducer, and the reducer passes through the coupling to the drive shaft and then by a pair of open gears to ensure that the two rollers are synchronized (equal speed with reverse direction). The material stored in bins uniformly enter the forming hopper through the quantitative equipment.

The unit forming pressure of the material is changed from small to large, and it reaches the maximum at the center line of the pair of rolls. After the material passes the line, the forming pressure is rapidly reduced to make the material enter the off-ball state and smoothly take off from the mould.

Basic structure of briquette machine

It consists of three parts: the feeding part; the transmission part; the molding part.

The main parts of briquette machine

The main parts of briquette machine

1. The feeding part

It is mainly to realize the quantitative feeding to ensure that the material evenly enters between the rolls. The screw feeding device is driven by the electromagnetic speed regulating motor, and is rotated by the pulley and the worm reducer to force the pressed material into the main feeding port.

Due to the constant moment characteristic of the electromagnetic speed regulating motor, when the amount of material of the screw feeder is equal to the amount of material required by the main engine, a constant supply pressure can be maintained to gain the high quality of the pellet.

If the feeding is too large, the feeding device is overloaded; if the feeding is too small, the briquette can not be formed. Therefore, the skilled operation technique is an important condition for ensuring the normal operation of the machine.

2. The transmission part

Its main drive system consists of motor, triangular belt, reducer, open style gear and roll. The main engine is driven by an electromagnetic speed regulating motor, which is transmitted to the driving shaft through a pulley and a cylindrical gear reducer, and then through a pin and pin coupling. The drive shaft and the passive shaft ensure synchronized operation through open gears.

The passive bearing housing is equipped with hydraulics at the rear. A hydraulic pump generates high-pressure oil into the cylinder to cause axial displacement of the piston, thus protecting the machine. The front joint of the piston rod is placed on the bearing housing to meet production pressure requirements.

3. The molding part

It mainly refers to the main engine part, and the core part is the roll. When the feed between the two pressure rollers is too much or enters the metals, the hydraulic cylinder piston rod is overload.

Next the hydraulic pump will stop working, the accumulator will buffer the pressure change, the overflow valve will open for oil return, and the piston rod will be displaced to widen the gap between the pressure roller to allow the hard object to pass through the roller.

Finally, the system pressure returns to normal, thereby protecting the pressure roller from damage.

5 main types of briquette machines

There are many types of briquette machines that can be used for charcoal briquetting on the market. Users can choose a suitable one according to their own production requirements, shape and size, quality requirements and the use of binders.

According to the different devices they are equipped, there are mainly 5 types of machines for briquetting.

1. Strong pressure briquette machine

Production capacity: 4-18 t/h, 25-70 t/h

Finished product shape: Round, pillow, oval, etc.

Applied materials: Coal powder, charcoal, wood charcoal, coconut charcoal, coal slime, coke powder, ore powder, gypsum, quicklime, mineral powder, etc.

3. Static pressure briquette machine

The static pressure briquetting machine is used to press the wet powder, that is, a certain proportion of water and other liquid binders are added to press the ball.

Production capacity: 2.2-40 t/h

Finished product shape: Round, pillow, oval, etc.

Applied materials: Charcoal and coal powder, coal slime, coke powder, ore powder, gypsum, quicklime, mineral powder, etc.

4. Dry powder briquette machine

The dry powder briquette machine has a cushioning device to better protect the equipment from hard objects. It is designed with an adjustable device so that the mould is always within the adjustable range without displacement.

The briquette machine for dry powder does not need to add water, and can be forced to feed materials. If the material needs a large pressure to be pressed, a hydraulic device can also be arranged.

Budget analysis for investing a briquette machine

In China, the price of ordinary charcoal powder is about $280 a ton, and the price of charcoal briquette is $420 a ton. This shows that the profit from powder to briquette is 420-280 = $140.

Assuming a large briquette machine with a production of 40 t/h and a 10 hour work a day, and the daily output is 400 t. Then the user’s daily profit can be 40×10×140 = $ 56000.

Profit(per ton) Capacity Work hour(per day) Total profit(per day)
$140 40 t/h 10 h $56000

The price of a briquette machine

It can be seen that the profit brought by the machine for briquette is considerable without considering the price of the machine itself.

However, the specific price of the briquette machine is often various according to the dealer’s sales method(direct selling manufacturer or middleman) and the capacity. Actually, its market price is between $7000 and $21,000, which is negligible compared with the profit that the charcoal machine can bring. Users can choose the machine that suits their needs according to their actual requirements and economic strength.
