BHS-Sonthofen reported it built, shipped and oversaw the installation of the largest Combimix mixer system in company history for a zinc miner in India. The company reported its high-quality customizable technology and support helped it win the contract.
The mixer will be used on overburden and filter cakes to create a homogenous mass, free of clumping, for use as backfill.
The customer sought a mixer offering a longer retention time and a filling level below the mixing shaft. BHS-Sonthofen said that, to meet the requirements, the company first did extensive testing. “With a throughput of 263 m3/hr, we arrived at a retention time of about 137 seconds,” Sebastian Poppel, design engineer, BHS-Sonthofen, said. “During this time, lumps are dissolved to our satisfaction thanks to the high-performance mixing unit.”
The customer also wanted a solution that offered easy cleaning and maintenance.
Production of the unit was completed in August 2019, the company reported. It was transported on a ship. Installation occurred in late 2019 with the assistance of BHS-Sonthofen personnel.
