Largest Hydro-Clean unit delivered to the US

THE first HC 2000 –– the largest model in the Hydro-Clean series of high-pressure washing systems from Haver & Boecker –– has recently been delivered to a customer in North America.

The Hydro-Clean series now comprises the HC 350, HC 700, HC 1000 and HC 2000. The smallest model, the HC 350, is primarily used for exploration work in the diamond industry, while the largest machine, the new HC 2000, has been developed for high material throughput rates, especially in sand and gravel applications. On all four models, parameters such as the pressure level, nozzle count, mounting angle of the washing rotor and other settings can be adjusted to suit the specific application requirements.

The recently delivered HC 2000 Hydro-Clean is being used in the sand and gravel industry in California, where its main job is to wash approximately 140 tons/h of unclean 0–50mm gravel to remove agglomerates and reduce soft stone content as part of a process to produce an end product that is ready for sale. In terms of water and power consumption, the HC 2000 is using a modest 0.31m³ per ton and 1.29kW/h per ton respectively.

An innovative washing drum design is the most prominent feature of the HC 2000 Hydro-Clean machine. In contrast to the other models in the range, which are equipped with a single washing rotor, the HC 2000 has two rotors. Both are positioned in line alongside each other and share a common bunker, washing drum and discharge belt conveyor. However, in common with the other Hydro-Clean models, operation and adjustment of all parameters is via a touch-screen control panel.

The Hydro-Clean 2000 measures 3.2m x 3.5m x 3.7m and weighs 14.7 tons. For ease of transport from Haver & Boecker’s manufacturing facility in Germany to the job site in the US, the machine was designed in modular form to allow for partial disassembly for shipment by sea using standard containers.
