Single Shaft Mixers

UNIQUE BEARING AND SEAL DESIGN

The specially designed Bearing and Single Shaft Mixer seal group consists of a number of metallic and polyurethane components. The bearings are place on the outside of the mixer in the specially designed housing, which prevents the ingress of cementitious grouts, if a seal failure should occur, therefore, with the correct routine maintenance, the life expectancy of each bearing can exceed 500,000 m³ of production. The Labyrinth seal structure encapsulates the grease provided by the automated greasing system, to create a seal, preventing the grout from penetrating the bearing.

PERFECT LUBRICATION SYSTEM

The Centralized automatic lubrication system, continuously supplies the mixer labyrinth seals, with sensors on each seal, to ensure, you are informed of a failure, before it is too late.

UNIQUE PADDLE STRUCTURE

The Single Shaft Mixer paddle structure has been specifically designed for strength and abrasion resistance. Each Pallet group attached to a helicoidal main shaft has been reinforced against failure, and the concave structure improves life expectancy. The design and quality of our mixer paddle structures, are market leading and the quality is often compared to many German products on the market today. The life expectancy of the mixing group, is equal to the abrasion proof liners and cast thickness of the mixer structure, therefore, the life expectancy of Hamac equipment is more than often, in excess of many of our competitors.
