Steele Primary Crushers
— Cost-effective, reliable sizing for bulk raw materials
Robust, workhorse machines built for decades of reliable sizing and consistent output, with minimal maintenance, easy wear part replacement and fast change outs for drives and roll speeds.
Steele crushers improve bulk raw material preparation, for better mix quality and homogenous blending. They deliver consistent output of small particles (one inch or below), eliminating overloads on secondary crushing machines and lowering maintenance costs.
Model A Primary Crusher
- Parallel shaft gearboxes drive coarse or fine grind output
- Coarse-ground materials 1-4”
- Fine-ground materials 1/2-2”
- Fine grind increases output
- Minimizes wear and additional processing by secondary/tertiary grinders
- Available with coarse and fine grind options
Ductile iron discs mounted on an 8-inch square shaft form our crushing rolls, with steel alloy teeth designed for easy removal (you can specify teeth for production requirements).
Built to last
Like all Steele machines, our primary crushers are built for decades of service — supported by our global service and parts network. We make primary frames with heavy ductile iron castings and use oversized gearboxes with high thermal ratings for a longer service life.
Roll shafts allow for roll space adjustment to change output size or adjust for wear. An integral system monitors torsional loading on roller shafts and bending loads on the crushing rolls, to shut down motors when it detects overloads.
