The stone separator Stonefex removes stones and inert items reliably and very effectively from biomass fuels. A patented system of pressure and suction blowers generates exactly the right air flow in the expansion chamber to remove stones and heavy objects from wood.
The outcome is a fuel nearly free of stones which can be sold at a higher price. Furthermore fractions that were previously unusable due to their high amount of stones can now be processed into fuel.
It pays off
The Stonefex improves fuel quality by removing more than 90 percent of stones and insert materials. Biomass processors profit from better customer acceptance of their fuels, higher sale prices, and the ability to make a saleable product from material contaminated with stones.
Everywhere applicable
The input material to the Stonefex is usually a usable biofuel fraction with a particle size from 10…20-150 mm for example:
Mobile and economically
The single-axle trailer configuration makes the machine easy to manoeuvre, and it is approved for 80 km/h road speeds, so transportation to the site is no problem. The standard version of the stone separator uses grid electrical power. As an option, a diesel generator is available.
Patented separating system
The input material is loaded onto the intake conveyor.
In the expansion chamber, a patented system of pressure and suction blowers separates the material into a stone fraction and a cleaned usable fraction, which conveyors take out to opposite sides. Fines and any light materials are collected in the container downstream of the suction fan.
