About RUF: Hans Ruf founded RUF Briquetting Systems, located in Zaisertshofen, Bavaria, in 1969. Today his sons Roland and Wolfgang run the company. More than 100 employees develop and produce briquetting systems & solutions on a modular basis suitable to make briquettes from wood, metal and other residual materials. The smallest unit features a 4kW motor and a throughput rate of 20 to 150 kg per hour (depending on material and chips size). The biggest unit featuring a 90 kW motor achieves a throughput rate of up to 5,000kg per hour (depending on the material).

Since the beginning of civilization, humans have tried to store and intensify energy. Methods used were as simple as drying, bundling and bailing to compact loose combustible material for fuel making purposes. Modern briquetting is simple, but only because of the tremendous know-how accumulated over time that the briquetting press manufacturers have put into numerous complex technologies. Today, most briquettes are made on technically advanced and highly automated mechanical, hydraulic or screw extruder briquetting lines. Seen in a historical context, briquetting on a commercial level is a relatively new phenomenon with the first industrial plants dating back to the second part of the 19th century.
