Double Drums Sewage Grinder

Pipeline grinder can be installed in variety of diameter pipelines to crush the solids to 8mm*12mm particles.

Product advantage

Operation Principle

• 1． Solids enter grinders through open channel；
• 2．Solids pass through cutters for size reduction.；
• 3．Solids are cut into smaller particles and no threat to downstream equipment.
