At the end of 2019, DHM GROUP signed a Contract for the design, manufacture and supply of a combined suspended taphole drilling and mud gun machine for a mineral wool manufacturer – ROCKWOOL.
DHM GROUP has fulfilled the order in due time. ROCKWOOL independently carried out the installation of the main components: a pump and an accumulator stations, overhead craneway and a combined machine. All work was carried out using plans and instructions previously developed by our specialists. Then the DHM GROUP’s technicians flew to Norway and carried out the first stage of commissioning machines, including installation check, preliminary equipment adjustment, the hydraulic, pneumatic and electrical systems set up.
The final stage of adjustment and commissioning of the taphole drilling and mud gun machines took place in February 2021. A group of our specialists checked the machines operation in manual and automatic modes, and also conducted trainings for service personnel and operators. Experienced operators from France also participated in the training and shared their skills with younger colleagues.
DHM GROUP once again confirms the status of a reliable manufacturer and supplier of high-quality for taphole drilling and mud gun equipment.
