Komptech Cribus 3800 Core Features

1Easy Maintenance Access

The drum sidewall easily folds down hydraulically, enabling efficient, direct access to the drum. Changing drums can be completed in as little as a few minutes and without extra tools. Large panels and doors throughout the machine give quick access to all maintenance points.

2Keep A Clean Drum

An electrically adjustable round brush, with available remote control, keeps the drum clean during operation. The feed cross-section to the drum, the drum diameter and the gap to the sidewalls help prevent clogs and allows a smooth screening-off process – even with large screen hole size.

3Low-Wear Discharge System

The Cribus 3800 trommel screen features a collector conveyor which moves against the material movement in the drum. Lower conveyor loading reduces wear and energy consumption and the corrugated side and fines discharge conveyor prevents leakage.

4Efficient Drum Drive

The maintenance-free drum drive features a high-efficiency, friction wheel drive with patented WHEELGRIP anti-slip technology to prevent slippage and produce maximum efficiency. Even support wheel loading through all-wheel drive minimizes wear.
