How Briquetting Press works?

Briquetting press may be of varying kinds but its objective of producing environmental friendly biomass fuel remains the same. Ideally, a briquetting press is utilized to compress waste, which is then transformed into renewable source of energy. Briquetting press is a kind of a machine that first crushes waste such as saw dust, bamboo dust, wheat husk, ground-nut etc and then this waste is dried and carbonize so that it can be used as fuel. This type of technology is extremely useful in the rural areas where good use is made of the waste available thereby ensuring cost effective and environmental friendly fuel is used.

Different types of Briquetting Press

Briquetting press is available as both screw as well as piston models. Where screw model is concerned, the biomass is screwed forward through a nozzle under extremely high pressure. In the second case also pressure is forwarded but through a piston. These are the two main methods through which it is formed into a cylindrical shape.

For one method binding agent is used while the other method is processed without binding method. When briquetting takes place without binding, it needs a raw material that contains maximum of up to 15 per cent and also requires a briquetting press that can produce pressure of a minimum of 1000 kg/cm2.

The minimum pressure can range and is completely dependent on the type of raw material that is being pressed. When briquetting is done with binding then it doesn’t need low moisture content because that can differ based on the kind of raw materials used. Therefore in a nutshell, the four important parameters of the briquetting process are moisture, binding agent, the size of the particle and the level of pressure used.

Usage of Briquetting Press in Rural Areas

Briquetting Press is extremely suitable for villages and ideally the right kind of briquetting press should be able to properly meet the following requirements:

• It is important that briquetting press remains eco-friendly thereby becoming an ideal alternative for fossil fuels.
• It has to be affordable so that it can be established easily in the rural village.
• It is also important that the briquetting press can be repaired using local materials.
