The shale is quarried at a depth of about 25 meters below ground level, is transported by truck to storage piles and from there to the crushers. These machines brake the shale down into small particles of 1 – 10 mm. The particles are then transported to the feeder of the power plant combustor. This combustion process deposits the Alganite® residue at a temperature of 180° C.This is followed by a screening process and the resulting dust is collected by an air suction system. The product is transported under a low pressure pipe conveying system (which also contributes to additional dust removal) to storage tanks.

Market-Minded Alganite® Production

Our goal is to produce a product that meets the needs of your market. The product can be adapted to your needs regarding particle size distribution and packaging.

At present Alganite® is produced in two different particle sizes:

• from 0.5 mm – 7.0 mm
• from 0.5 mm – 4.0 mm

However, Alganite® can be produced for different size distributions according to market needs.

Quality Control System

Production quality is closely monitored so as to ensure that the main product quality variables are consistently maintained and are within the range of the parameters that are now generally applied in Europe. These variables are absorption, particle size distribution, density, color and dry matter.

Most of the above-mentioned properties of the product can be controlled by determining the amount of organic material in the shale and the temperature of combustion. The quality control system applied at the plant is fully automated.
