Grinding Sludge Goes Green. Briquetting for the Environment
To briquette grinding sludge, it must first be transferred from the machine into the briquetter. Once inside, the sludge is compressed—squeezing out excess oils and fluids—while transforming the metal chips into metal briquettes. The oil pressed out during the briquetting process can be pumped directly from the briquetter into tanks.
