Used Pugmills

Overview

Pugmills are industrial mixers that blend clay, water and additives into a uniform, plastic clay body for ceramics. Available as batch or continuous units, they use rotating shafts, paddles or knives and sometimes vacuum de-airing to remove air and condition the mix. Pugmills range from small lab-sized machines to heavy production units and are chosen for capacity, discharge type, and ease of maintenance.

FAQ

What capacity and cycle rate should I choose?

Match capacity to your production rate and clay drying line. Specify batch size (kg or lbs), throughput (kg/hr), and discharge style (ram, auger, or belt) to ensure the pugmill keeps up with downstream equipment.

How do I inspect a used pugmill before buying?

Check shaft alignment, paddle wear, seals, bearings, drive motors, and the condition of the barrel and discharge. Run it if possible to listen for unusual noises and verify mixing consistency and vacuum function.

What electrical or hydraulic requirements should I confirm?

Confirm motor voltage, phase and frequency, rated horsepower, control panel compatibility, and any hydraulic pump pressures or flow rates. Verify wiring and starter condition for safe hookup.

How should a pugmill be shipped and secured?

Pugmills are heavy and should be crated or strapped to a flatbed with lifting points identified. Disassemble removable parts to reduce height and weight. Use a carrier experienced with heavy industrial equipment and get weight/width permits if oversized.

What are the most common wear parts and maintenance tasks?

Replace paddles/knives, seals, bearings, wear liners and gaskets regularly. Grease bearings, check shaft clearance, inspect drive belts/chains, and flush the vacuum system. Schedule rebuilds based on hours and abrasive clay use.

Are spare parts and service available for older models?

Availability varies by manufacturer. Ask the seller for part lists, serial numbers, and any service history. Many common parts are rebuildable or can be retrofitted, but confirm lead times for critical components.
