Cement Products

A&J Mixing manufactures Severe Duty machinery for the cement industry in both single rotor and double rotor designs. The cement industry is an important part of our sales.

Our first development was a single rotor paddle mixer with Shearmakers designed specifically to develop red and salmon colors in masonry cement with a mixing rate of 3.5 tonnes in 3 minutes with only 160 hp (1 x 40 hp main drive, 8 x 15 hp Shearmakers).

The rotor will mix pigment in one minute, and the aggressive Shearmakers will repeatedly develop the color in a predictable time, a major break through.

We have never failed a color test and users have reduced pigments.

In addition to performance, it is mechanically designed to give seal life of one year or better, which means more production and less down time.

Investment and operating costs are lower.

The mixer is available with 400 minimum Brinell hardness abrasion resisting plate for the housing sides and paddle faces, a popular option.

Severe duty peripherals are also developed including discharges, bag dumps, weigh hoppers, discharge hoppers to feed baggers. All levels of controls are available.

Performance guaranteed per our T&C.
