Masa presents new, service-oriented features
Concrete mixers PH 2000/3000 and S 350/500Andernach 3 Aug 2022 - Masa will be exhibiting the PH 2000/3000 mixer optimized for main mix concrete production and the special S 350/500 face mix mixer at bauma 2022, along with other interesting exhibits. For both models, Masa engineers developed new, service-oriented features over the past months, which will be shown there for the first time.
The quality of raw materials plays a decisive factor in being able to achieve a homogenous mix of high-quality concrete inside the mixers. Both the raw materials and mixers significantly influence the appearance and performance of the finished concrete products. The production of main mix and face mix concrete have different criteria meaning the respective mixers require specific solution-based approaches. While in main mix concrete production, the primary requirement is to achieve the highest possible quantity of concrete while maintaining the quality, the focus in face mix concrete production is on achieving the highest possible quality while limiting the quantity to small batches. In addition to the pure performance of a mixer, plant operators value its serviceability and ease of maintenance.
Stagnation is regression
That is why the mixer specialists at Masa do not lose sight of continuing to optimize our products. Both small, detailed modifications and larger improvements to the concrete mixers contribute in total to results that can be proud of.
The modifications to the PH 2000/3000 as well as to the S350/500 that will be presented at bauma 2022 are aimed at optimizing both the function of the mixer and the ease of maintenance.
PH 2000/3000
- Modification baffle plates: Following analyses in various customer plants, Masa has now moved the baffle plates installed below the mixer to the top, which has significantly improved the uniformity in the filling of the bucket conveyor. Local cone formation or segregation, but also subsequent adhesion should be avoided.
- Large inspection opening: Continuously assessing the degree of wear to the ring gear, pinion, and motor as well as monitoring the level of gear oil is essential for high plant uptime. Masa engineers have now developed a very convenient inspection opening for this purpose. The easily removable shutter of the opening has a diameter of 460 mm giving the plant operator a comprehensive, and if necessary, camera-supported view into the gearbox.
- Modification of the attachment points of the mixing arms and the side scrapers, which has a positive effect on the service life of the mixing arms and the cleanliness of the mixing trough.
- Further small improvements to optimize maintenance intervals and work.
S 350/500
- Improved accessibility to the main drive of the mixing trough: The design of the lower steel frame was modified. Screw connections now make it easier to remove the side cover plate, which clears the way to the motor. The designers created the possibility to drive under the motor with a scissor jack, lower the motor and pinion, and drive out sideways. Locking screws ensure precise positioning of the pinion and ring gear during subsequent reassembly. Masa reduces the corresponding downtime by more than 50% with this modification.
- Easy maintenance access to the Bluetooth probe: The Bluetooth probe, which is optionally available for the water dosing system, is positioned flush with the bottom of the mixing trough by means of a fastening ring. Depending on the degree of wear of the fastening ring and mixing trough lining, it may be necessary to adjust the probe. A small, easy-to-remove insert plate now allows direct and, above all, maintenance-friendly access from below, and the adjustment can be made using adjustment screws. For the plant operator, this means significant time savings during probe adjustment or probe replacement, which is an indispensable component to achieving reliable measurement results.
- Improved motor accessibility: The drive motor for the rotating bottom cover of the mixing trough, which was previously mounted on the side, sits on a stand in the modified version and is now more easily accessible. The sealing joint on the closing lid is blown off so that the lid always closes cleanly.
