A double roller type magnetic machine typically refers to a magnetic separator or processing equipment that uses two rotating rollers with magnetic properties to separate or manipulate materials based on their magnetic susceptibility. These machines are commonly used in industries like mining, recycling, and material processing.
Key Features & Working Principle:
1. Dual Roller Design:
– Consists of two parallel rollers, often made of stainless steel or other materials with embedded magnets (permanent or electromagnets).
– The rollers rotate in opposite directions or at different speeds to enhance separation efficiency.
2. Magnetic Separation Mechanism:
– Ferrous (magnetic) materials are attracted to the rollers and carried along their surface.
– Non-magnetic materials fall straight down due to gravity, separating them from the magnetic fraction.
3. Adjustable Magnetic Intensity:
– Some models allow adjusting the magnetic field strength (if electromagnets are used) for different material types.
4. Applications:
– Mineral processing (e.g., iron ore beneficiation).
– Recycling (e.g., separating ferrous metals from waste).
– Food/pharmaceutical industries (removing metal contaminants).
Advantages:
– High separation efficiency for fine and weakly magnetic particles.
– Continuous operation with minimal maintenance.
– Can handle both dry and wet materials (depending on design).

Common Variations:
– Dry Double Roller Magnetic Separator: Used for powdered or granular materials.
– Wet Double Roller Magnetic Separator: Used in slurry-based processes (e.g., kaolin clay purification).
