We combine various by-products and waste streams into briquettes suitable for re-use as raw materials. These briquettes are 100% waterproof and can withstand temperatures above 1000°C.
Briquetting of various fine materials have been practiced for a long period of time. The main purpose of briquetting is to agglomorate fine material into a bigger unit so that the better qualities of the bigger unit can be utilized to benefit the specific application.
Hydraulic briquetting presses are used for this purpose. They apply considerable force to compress the material into compact briquettes. This process changes the material properties in a way that creates a product similar to those of the solid raw material state. This is why briquettes can be used as a raw material in certain processes.
We make use of the briquetting technique to utilize all kinds of fine organic or anorganic materials, usually dispatched as waste or low value by-products. These briquettes are then recycled as a raw material feed for normal furnace operations.
The two main benefits of recycling these materials as briquettes back into the furnaces are:
- Economical solution for raw materials
- Long term environmental solution by utilizing every type of process waste
To make use of briquettes in furnaces, the briquettes need to have certain essential qualities to benefit furnace operations:
- Compaction strength – Due to the nature of furnace operations, briquettes are exposed to a rough environment and must be able to handle tough circumstances like HMV drive-overs.
- Handling strength – To survive the harsh environment of material loading and conveying systems to the furnaces, the briquettes need to be abrasive resistant.
- Water resistance – Not all furnace operations have the benefit of under roof storage of raw materials to protect the briquettes against the elements.
- High temperature strength – In all furnace processes it is essential that certain raw materials stay in their solid state up to specific temperatures before undergoing phase transitions.
You can press briquettes without binders by using very high hydraulic forces to compress the material to the accepted standard, usually by secondary machinery in the form of force feeders. Or you can do it by using specially formulated binders mixed with the fine material to agglomerate the particles together. Picko make use of binders.
Over a period of four years we have developed binders that can give the briquette enough strength to survive even the harshest of material handling environments and sustain the briquette up to 1100°C in the furnaces. Our binders are highly developed in all kinds of manganese-, chrome-, ferrous-, coal-wastes and by-products.
Every furnace operation is unique in itself, taking into consideration waste and by product materials. The binders, or combination of binders, are specifically developed and tested in our laboratory according to the clients’ briquetting application. We have managed to develop and produce successful briquettes for various ferro- and siliconmanganese furnace operations. These include high profile companies like BHPBilliton – Metalloys, Assmang – Cato Ridge, SiCarbide and also Renova – Transalloys.
