Cement Mixers & Mortar Mixers

cement industry

A&J manufactures cement and mortar mixers for in multiple configurations for a variety of industry uses. A&J began designing The Shearmaker™ for cement mixers, specifically, to develop red and salmon colors in masonry cement which is non-sanded, in a fixed time, and these are the colors we usually design for. There is a mallard green that takes longer, and our customers just take less production on this color as it is not a big seller. Lighter colors take less time but most customers can’t package any faster, so we work on a fixed time.

We are the only company who can develop color in non-sanded material.

Mixer Details

The PHLAUER™ patented mixer rotor is ideal for customizing and introducing high shear, making it one of the best cement mixers in the industry. The mixer is divided into zones with two paddles., an outer and inner that creates randomized flow in both directions. When adding a Shearmaker, we notch the paddle face to accommodate the Shearmaker blades. Any surface area removed is added to the other side of the paddle head as to not compromise the mixing action.
We just started a system that had enough Shearmakers to develop in six minutes and that is exactly the time we started up and packaged saleable material. We have installations up to 5 ton batches fully developing color in 3 minutes.
Adding sand to the Shearmaker cuts time in half, or you can use half the number of Shearmakers. You will save 5 to 17% of your pigments. Thinsets and mortars without color take one minute of mix time. We had one customer get a payback of 3 months because of quality and production capability from system designed by A & J.

Mixer Features

The rotor mixes to 1/2% standard deviation and Cv of 5% with one minute of mix time.

  • Load automatically and/or over the side – Less space required
  • Sealed Machine – requires dust collection only for manual loading. With the plenum connection, this reduces material in dust collector
  • Seals that last and easy, low cost repair: Some customers PM just once per year
  • End plates and rotors are re-straightened for proper seal presentation
  • Shearmaker seals are patented controlled orifice seals air-purged (COSAP). The sealing is just a film of air
  • Variety of discharges: heavy duty drop bottom, single port, dual port, end discharge – up to 3 on one machine all discharging at same rate. 8:1 power to load ratio, self adjusting
  • Low horsepower and low maintenance
  • Lower cost per ton
  • Custom for your exact needs including the hoppers and controls
  • Paddles and housing sides of 400 min. BHN heat treated alloy plate
  • Reverse knife edge sealed cover for flush top to load bags
  • Stand-up heavy-duty pipe grate
  • Easy to clean
  • High volume. Each – Shearmaker will develop 12.5 cu. ft. (350 liters) of red in 3 minutes in non-sanded material. Sanded and lighter colors are faster
