Concrete Mixer Paddles, Arms and Liner Plates

Which mixer parts wear out?

The mixer is the part of a batching plant that wears fastest: aggregate and cement rub against the paddles and the inside of the trough in every batch. We supply wear parts for twin-shaft and planetary mixers of different brands and models, not only for our own plants.

• Mixing paddles: bolted to the arms; twin-shaft mixers use right-hand and left-hand paddles.
• Arms: connect the paddles to the shaft and can bend or break under impact.
• Liner plates: replaceable wear plates that protect the side walls and floor of the trough.
• End scrapers: keep concrete from building up on the end walls.
• Shaft seals and lubrication parts: seal sets, grease pumps and distributors.
• Discharge gate parts: gate seals, hydraulic cylinder and hand pump.
• Planetary mixer parts: mixing paddles, side and bottom scrapers, floor and side liners.

When to replace

• The gap between paddles and liners grows and a concrete layer forms in the trough.
• Mixing time increases, or the mix is no longer homogeneous with the same recipe.
• Liner plates become thin or holed, or bolt heads wear down.
• Slurry leaks from the shaft ends or bearing noise increases.

Paddles are usually replaced as a set. See our twin-shaft mixer guide for maintenance.
