Steele Smooth Roll Crusher
— Medium to fine grinding to produce discs, strips or sheets of material
The Steele Smooth Roll Crusher plays a key role in bulk raw material preparation, processing clays, coal fines, coke breeze and gypsum waste. Twin rollers reduce pebbles and plastic lumps to form thin, flat discs, strips or sheets of material for additional processing or pugging.
Crushing and shearing improve mix quality, so we use a twin-speed roller design. The slow roller turns at approximately 280 rpm and is paired with a fast roller running at approximately 290 rpm.
Improved shearing action for better mixing
The slow roller’s face width is sprung, so uncrushable objects can pass through without damaging the machine. The fast roller is fixed, not sprung. The difference in rpm generates additional shearing and improves self-cleaning on the roll shell surfaces.
We cast our rollers with a high chrome alloy renewable shell, to extend periods between required resurfacing. Steele recommends maintaining spare smooth rollers mounted on centers and shafts, for resurfacing and exchange with worn rollers as necessary.
Reliable operation with minimal maintenance
Our smooth roll crusher, like all Steele machinery, is built for decades of reliable operation. Spherical roller bearings are self-aligning and grease lubricated. Castings, other than wear parts, are virtually indestructible ductile SG iron.
Materials processing
- Wet, sticky clays
- Shales
- Soft limestone
- Fireclays
- Other dry materials
Input material
- Typically uses ¼” output of disintegrator, but handles soft materials as large as 2” (51mm)
Output size
- As low as 1/16” (1.6mm), with a practical minimum roll spacing of 1/8” (3.2mm)
Throughput
- Up to 70 tons per hour with a 1/8” (3.2mm) gap, depending on feed material
Industry Applications
- Intermediate smashing and flattening for clay working applications in brick, block and tile
- Smashing coal fines, coke breeze or gypsum waste
