Cleaning mixing equipment is a challenging task that the MixerWasher handles efficiently and in an environmentally friendly way. The MixerWasher is a tank cleaner with an electric geared motor, developed for cleaning mixers such as concrete and cement mixers as well as production, storage and transport tanks. It consists of the RW cleaning head, a connecting pipe, a mounting flange and the electric motor.
The geared motor generates the rotary motion and transmits it via the motor drive shaft and the connecting pipe to the cleaning head, which is inclined at 45°. As the head rotates at 14 rpm, the two nozzles achieve a jet coverage of 270°; a complete cycle takes approx. 4.1 minutes. The high-pressure water is connected at the connecting pipe and routed to the cleaning head. Only the cleaning head and the connecting pipe enter the tank; the mounting flange can be slid along the pipe and clamped in the desired position.
Speed and torque are matched to the cleaning task. Thanks to the modular design, the individual components can be replaced, so the unit is quickly ready for use again after servicing. The robust design of the components, especially the cleaning head, is specially tailored to the requirements of the concrete industry – a reliable tool that is always ready for use. The MixerWasher is designed for durability, is easy to maintain and complies with the applicable directives and standards. Special versions are available on request – contact us directly.
In planetary and pan mixers, cleaning affects wear, availability and product quality. Several high-pressure cleaning heads permanently installed in the mixer lid (3 to 4 depending on mixer size), supplied by a pump unit delivering at least 120 bar and 50 l/min, clean the mixer automatically with the lid closed. The 45° angle in the swivel joint deliberately leaves out the upper part of the mixer; solid-stream nozzles ensure high impact pressure, and all rotating points are sealed against dust.
- Time: basic cleaning in approx. 10 minutes instead of 50 to 60 minutes by hand – with correspondingly shorter downtime.
- Staff: the operator only needs to check the cleaning result.
- Water: experience shows water consumption is halved compared with manual cleaning – lower fresh water and waste water costs.
- Cleanliness: no splash water around the mixer.
Existing mixers can often be retrofitted if mounting openings are provided in the mixer lid. A detailed description including a cost-efficiency example is available in the PDF Mixer Washer – cleaning concrete mixers (German). We will be happy to prepare a concept and quotation for your mixer cleaning.
