HUBER Coarse Screen TrashMax® Sturdy screen for coarse material separation

Cable operated coarse screen for:

  • Pumping station protection
  • Seawater intake
  • Surface water intake
  • Sewage treatment plants

The HUBER Coarse Screen TrashMax® is a highly effective solution for protecting downstream systems. It is ideally suited for pumping stations, the first treatment stage in wastewater treatment plants, industrial plants, and the inlet to power plants. This screen efficiently removes coarse and bulky materials, protecting downstream sensitive equipment and processes.

The TrashMax® excels in demanding environments, providing reliable protection and minimizing the risk of damage to downstream systems due to its high-capacity screen rakes and the high operational safety due to efficient and reliable screen rack cleaning.

Design and Function

The HUBER Coarse Screen TrashMax® features an efficient and adaptable cleaning system designed for high-capacity screenings removal. The cleaning elements, attached to a chain system, are easily adjustable to accommodate varying requirements, enabling the removal of heavy and bulky objects. This flexibility allows the removal capacity to be tailored to meet the needs of specific installations, making it particularly beneficial for areas with high solids loads.

The installation height of the HUBER Coarse Screen TrashMax® above ground level is minimal and depends only on the installation height of the screenings transport or disposal units, even for deep channels. Both ends of the cleaning rakes are securely connected to robust drive chains. Each rake is guided by two wear-resistant rollers on either side, which run smoothly in lateral guide tracks to ensure reliable and thorough screen rack cleaning. The chains are powered by sprockets mounted on a common shaft and driven by a gear motor.

The rakes of the TrashMax® screen engage with the screen rack bars at the bottom dead center, first cleaning the rear of the screen rack and then the front. This operational design prevents material buildup in front of the screen, allowing even large, bulky debris to be effectively removed and transported upward out of the channel.

The lower section of the HUBER Coarse Screen TrashMax® features a steep conveying segment, followed by an upper section with a gently inclined, flat discharge area. This design ensures the efficient and reliable discharge of screenings into downstream transport or disposal systems.

FAQ

Frequently Asked Questions

Machines with a steep installation angle are best suited for such applications.

This screen installation option allows the installation space to be very compact, especially in the direction of flow.

Typical examples are our HUBER Multi-Rake Bar Screens RakeMax® and RakeMax® CF as well as the HUBER Belt Screen EscaMax®, HUBER Coarse Screen TrashMax® and HUBER Grab Screen TrashLift.

The best possible screenings discharge capacity is achieved with screens that have several rakes. The number of rakes can be adjusted to suit the conditions.

In addition, screenings discharge capacity can also be influenced via the discharge speed, e.g. through drives controlled by frequency converters.
