GEMCO started its business exporting the YZL (6YL) series small-sized oil press in 1997. The machine was originally designed to produce agricultural crude oil. After years of innovation we successfully built corollary equipment to further process crude oil into edible oil. In response to some clients who used the oil press for biodiesel preprocessing, we then established a biodiesel initiative to provide consultation and aid for biodiesel processing. From 2002 to 2004, GEMCO was the largest Chinese oil press exporter in China according to official customs’ statistics.

In 2005, GEMCO began exporting small-sized pellet mills used for traditional feed pellet processing. However, some of our clients succeeded in applying the machines to biomass pellet production. This inspired us to enter the biomass energy industry. After intensive study and research, we concluded that our feed pellet machines could in fact produce wood pellets, but since little or no binder is added in the pelletization process the useable life of the machine was shortened. Given these facts, GEMCO established a research and development department in 2007 focusing on biomass machinery design and technological innovation. After countless trials and modifications, we finally succeeded in building the GEMCO ZLSP series pellet mill. It broke through the limits faced by the feed pellet machine when utilized for wood pellet production and meets the needs of commercialized biomass pellet production.

GEMCO currently possesses several core patented technologies in the field of biomass pellet production. Besides small-sized pellet mills, GEMCO also provides pellet mills and complete pellet production lines with capacities of over two tons per hour. We provide a complete range of services to include design, manufacture, installation, debugging and training. To present, GEMCO has completed several pellet production lines across Europe, Asia, the Americas and Africa. In 2009 and 2010, GEMCO was China’s largest exporter of pellet machines according to official customs’ statistics.
Along with the development of the biomass pellet equipment, GEMCO also devotes its efforts to the fields of biomass briquette production and biomass carbonization. We have numerous kinds of briquette machines for customers to choose, including both screw and hydraulic presses. Different accessories are also available.
