In mining, aggregate, and material handling environments, water is one of the most stubborn operational challenges. It sticks to belts, adds unnecessary weight, reduces flowability, and causes costly material buildup. That’s why operations across the country trust Cogar Manufacturing’s Underdrum Dewatering System—a rugged, low-maintenance solution designed to remove excess water right at the conveyor discharge point.
That’s why leading operations across the U.S. rely on Cogar Manufacturing’s Patented Underdrum Dewatering Systems, protected under U.S. Patent No. US8,147,689 B1. These units are engineered for rugged reliability, maximum water removal, and efficiency in the toughest environments, built for confined spaces.
Why Dewatering at the Conveyor Discharge Matters
Excess water in material handling causes:
- Higher transportation and cleanup costs
- Reduced material flow and belt efficiency
- Premature wear on equipment
Cogar’s underdrum system tackles the problem directly at the discharge point, ensuring your operation moves drier, lighter, and cleaner material through every stage of production.
How Cogar’s Underdrum Dewatering System Works
Our patented underdrum dewatering unit (US8,147,689 B1) is mounted beneath the head pulley of a conveyor belt. As wet material discharges, the unit captures and channels water away before it creates problems downstream.
With field-proven durability, our system includes:
- Corrosion-resistant stainless steel construction
- High-efficiency water removal performance
- Minimal maintenance design
- Custom-built configurations for your belt specs


Built for Demanding Operations
From salt mines to coal prep facilities, Cogar’s patented underdrum system is trusted to perform in some of the most aggressive, high-moisture environments in the industry. With solid-state durability and performance you can count on, these units help reduce downtime and material loss.
