Steel mould for biogas digester

The steel mould is composed of decades of steel moulding boards and work pieces. The steel mould is applied to construct the concrete digester of the Puxin biogas plant. It is a very simple and easy job to build the concrete digester by applying the steel mould, because for the constructers the blueprints are not needed, to master the steel mould is the only skill required. So, the speed and quality of the construction can be greatly increased by using the steel mould. By using a steel mould a 6 or 10 m3 Puxin biogas digester can be build in two days, or 150 in a year. The steel mould is reusable and can be used over 2000 times, last over ten years.
