Getech spins centrifugal washwater cleaner into tunnelling applications

Getech, the Italian manufacturer of centrifugal washwater cleaning systems (formerly Gennaretti) is targeting tunnelling operations with containerised versions of its V type machines. The five-machine range can remove up to 60tonnes an hour of solids from washwater flows of up to 180m3/hr.

Centrifugal separators are compact and suited to operation in confined spaces.
7186 Getech, the Italian manufacturer of centrifugal washwater cleaning systems (formerly Gennaretti) is targeting tunnelling operations with containerised versions of its V type machines.

The five-machine range can remove up to 60tonnes an hour of solids from washwater flows of up to 180m3/hr.

The system uses a rotating helical flight shaft (similar to an Archimedes screw) to separate the solids using centrifugal force in the same was as a cyclone air filter. As the contaminants are thrown outwards, the helix pushes them along the machine towards a narrowing taper, which separates the excess water from the solids.

According to the company, the system is only a fraction the size of a traditional filtration plant, making it ideal for tunnelling operations. The water it produces is 99% clean while the outlet cake has a dryness of 65%.

Although the system will accept bigger contaminants, ideally the maximum particle size in the infeed water should be kept to around 73microns to minimise wear.

The system can also recover bentonite from the drilling sludge for re-use and the scroll has a metalised anti-wear surface finish.

    February 7, 2013
    Synthetic diamond division of DeBeers, Element Six, has developed the 3D Percussive Diamond Insert (PDI) that it claims will radically cut costs in the mining drill industry. The 3D PDI uses the firm’s polycrystalline diamond technology to optimise wear and impact resistance properties, while improving penetration rates for the drill bit. The firm claims that tests of the drill insert show up to 10 times the drill life of a conventional tungsten carbide insert., greatly reducing costly rig downtime for serv

    Wirtgen’s novel inspection system offers a quick indication of wear rates on the cutting tools of the firm’s surface miners. Called the Wirtgen Pick Inspection (WPI) system, this tool comprises eight sensors that can make fast measurements and which are integrated into the cutting drum compartment of the surface miner. The sensors measure the degree of wear of the picks and the measuring process takes just one minute to complete, allowing it to carried out while changing trucks and reducing downtimes. The W
