<p>The cleaner for the interior of a concrete mixer, comprises nozzles (1) connected together and to a high-pressure water pump (3). The nozzles are aimed so that their jets penetrate inside the mixer, and are typically mounted opposite its loading opening. This keeps the interior of the mixer free from deposits of concrete, which would otherwise have to be chipped free regularly, with consequent risk of damage to the mixer drum and blades. The pump has an output regulated to be in the range of ten and one hundred and fifty atmospheres.</p> |
