Types of Used Mills Available
Aaron Equipment offers a range of used mills designed to support size reduction, grinding, and material processing applications:
Hammer Mills – High-speed impact mills used to crush and grind materials into smaller particles through repeated hammering action.
Ball Mills – Rotating mills that use grinding media to reduce material size through impact and attrition.
Roller Mills – Compression mills that reduce material size by passing it between rotating rollers for controlled particle sizing.
Colloid Mills – High-shear mills designed for emulsifying, dispersing, and fine grinding of liquids and semi-solids.
Pin Mills – Fine grinding mills that use intermeshing pins to achieve uniform particle size reduction.
Sand & Media Mills – Wet grinding mills that use media agitation for fine dispersion and particle size reduction in slurries.
Mill Applications & Industry Uses
Used mills are essential across industries where particle size reduction and material conditioning are required. Common applications include:
Chemical Processing: Grinding powders, pigments, and intermediates
Food & Beverage: Milling grains, spices, and ingredients
Pharmaceutical Manufacturing: Fine particle size reduction for formulations
Minerals & Mining: Crushing and grinding ores and aggregates
Plastics & Polymers: Size reduction of pellets and regrind materials
These systems improve material consistency, increase surface area, and enhance downstream processing efficiency.
Used Mill Buying Considerations
When selecting a used mill, it is important to evaluate both process requirements and equipment condition:
Material Characteristics: Hardness, moisture content, and abrasiveness
Particle Size Requirements: Desired output size and uniformity
Grinding Method: Impact, compression, or attrition depending on application
Throughput Capacity: Match system output with production needs
Wear Components: Evaluate liners, hammers, or grinding media condition
Condition & Maintenance History: Review prior usage and service records

An industrial mill is a machine used to reduce the size of materials through grinding, crushing, or pulverizing. Mills are used to process solids into smaller particles for further manufacturing or processing.
Common types include hammer mills, ball mills, roller mills, colloid mills, pin mills, and media mills. Each type is designed for specific materials and size reduction methods.
Choosing the right mill depends on material properties, desired particle size, throughput requirements, and the appropriate grinding method for your process.
Yes. Used mills are built for long service life and can remain highly reliable when properly maintained, inspected, and refurbished if necessary.
Mills are used in chemical processing, food production, pharmaceuticals, mining, and plastics industries where size reduction is essential.
