Coke fine briquette machine – set up briquette plant with roller press

A coke briquette line in China

Coke fine briquette machine is used to recycle the coke fine which is treated as a waste in the industry. The selling price is very low for this waste compares to the lump coke, but briquette work changes this condition and turns it to be a useful and valuable resource.

Two common coke types

There are several types of cokes in the industry. The main coke fine for briquetting are the following two types

Petroleum coke

The petroleum coke is a byproduct of the petroleum refining process. Different quality petroleum coke has its specific usage in different industries, and most of them are used in the cement industry.

Coal coke

Coal coke is the main product of the coal coking process. Most of the coal coke is used in the steel plant to produce iron, so it has other names like blast furnace coke or metallurgy coke, etc.

There are also other type coke like the asphalt coke, but most of the coke need to briquette is the petroleum coke.

Chart: Applications of petroleum coke

Application	Coke Type	Status	Industry
Carbon source	needle coke	calcination	electrode; synthetic graphite.
	sponge coke	calcination	produce aluminum anode; TiO2 pigment; recarburizer.
	sponge coke	green coke	silicon carbide; foundry and glass factory; coke oven.
Fuel	sponge coke	lump green coke	industrial boilers; utilities; cement; lime; waste heat power generation; space heat source.
	sponge coke	green coke
	shot coke	green coke
	fluid coke	green coke
	flexible coking coke	green coke

Coke fine waste sources for briquette machine

Coke fine sources mainly come from these areas

from low coking temperature. It contains petroleum coke with the wrong operation and coke from lignite, this is something we call as green coke;
from the transportation and storage process;
from the pre-crushing process.

The world generates lots of coke every year (find the data from the chart below). Almost 10% of the coke finally become powder type in this way or that. In some cases, the rate can even be up to 30%.

Why recycle the coke fine by briquetting

Coke fine, most of which the recycle way is burning. Thus, briquetting becomes a very good way as the support.

Cokes are different in particle density, size, and even the internal structure. These make them quite different in chemical properties. It becomes hard to recycle them together in different fields.

But due to it high carbon rate, it is easy to use as a heat source, and briquette makes it easier to use. Briquette is a kind way to treat the waste coke in a way simple, easy and with low investment.

These certain coke fine also can be reused by briquetting and reduce our cost on the lump coke.

Make coke fine briquette with roller press

roller press

Coke is a kind of material with less plasticity, direct briquette is a not a possible way to deal with it. Therefore, in the briquetting process, we need to add other additives especially binder for making the briquette.

Roller briquette press machine is a common equipment which is used to make the coke briquette. The machine is with a single structure, easy to operate, and with a continuous working process.

The working principle

roller press working principle

After uniformly mixed with other materials, the coke then is fed into the briquette machine by it’s feeding hopper. Space becomes smaller and smaller when it going from the top to the center of the two rollers. Meanwhile, the briquetting pressure becomes larger and larger.

With the function of the binder, these mixed materials (mainly coke) combined together on the high pressure, and turns to briquette. As the roller moves down forward, the briquette output from the rollers, thus these dust becomes briquette.

Recycle the coke fine by setting up the coke briquette plant

Coke briquette process normally follows this way

Raw coke fine – crush (crusher) – mix with binder (mixer) – briquette (briquette machine) – drying (natural drying or dryer)

In this process, except the briquette machine, there are also other machines we will use for

Crusher

Raw coke is not all with the proper size for briquette, crush it first to get a size suitable for briquetting.

Mixer

Mixing is a very important process in briquette making, mix raw material well with binder helps to increase the forming rate and make better quality briquette.
