WHAT IS A ROTARY DRUM BATCH MIXER?
A rotary drum batch mixer is an industrial mixer that blends materials by gently tumbling them inside a rotating cylindrical drum. Unlike ribbon, paddle, or plow mixers, the rotary drum does not rely on a shaft-mounted agitator to move material.
Scott Equipment’s Rotary Drum Batch Mixer rotates forward and reverse while angled internal baffles continuously lift, tumble, and move material through the mixing chamber. This creates a consistent blend while minimizing product damage, buildup, and material left behind after discharge.
BEST SUITED FOR:
Heavy, free-flowing materials • Fragile products • Granules • Pellets • Powders • Coated products • Bulk solids
HOW DOES A ROTARY DRUM MIXER WORK?
Efficient Mixing
Material is gently tumbled as the drum rotates forward and reverse. Angled internal baffles create continuous crossflow and end-to-end material movement for fast, consistent blending.
Gentle mixing protects fragile materials
Angled baffles promote continuous material movement
Minimal dead zones
Consistent batch-to-batch blending
Handles batches as small as 10% of rated capacity
Complete cleanout
The simple drum design minimizes internal product contact points where material can collect. Smooth interior surfaces and the optional swing inlet/discharge door promote virtually complete product discharge.
Virtually 100% product discharge
Less material waste
Reduced cross-contamination
Faster cleaning between batches
Easy access to the drum interior
EASy MAINTENANCE
With fewer internal moving components than many shaft-driven mixer designs, the Rotary Drum provides a simple, durable solution for demanding production environments.
Bearings and seals remain outside the product zone
Fewer wear components
Easy access for inspection and maintenance
Heavy-duty construction
Long service life

ROTARY DRUM MIXER FAQs
What is a rotary drum mixer?
A rotary drum mixer blends materials by tumbling them inside a rotating cylindrical drum. Scott’s design uses forward/reverse rotation and angled internal baffles to create consistent material movement and blending.
What materials can a rotary drum mixer handle?
Rotary drum mixers are well suited for heavy, free-flowing, and fragile materials, including powders, granules, pellets, feed ingredients, minerals, food ingredients, and other bulk solids.
How fast does a Scott Rotary Drum Mixer mix?
Depending on the material and application, Scott Rotary Drum Mixers can achieve mix times as short as 30 seconds.
Does a rotary drum mixer completely discharge the product?
Scott’s Rotary Drum Mixer is designed for virtually 100% product discharge, helping reduce product waste, carryover, and cross-contamination.
Can a rotary drum mixer handle fragile products?
Yes. The gentle tumbling action makes rotary drum mixing particularly useful for materials that more aggressive mixing methods could damage.
Can I test my material before purchasing a mixer?
Yes. Scott Equipment offers material testing so customers can evaluate mixing performance before selecting a production system.
