Wet processing technology
efficient solutions meeting the most sophisticated demands
In the field of wet processing technology, SBM Mineral Processing offers innovative and powerful solutions for the natural stone industry, sand and gravel production, building materials recycling, slag processing and ore dressing. With a broad portfolio of machine types that are individually customised to specific requirements, SBM ensures optimum results in demanding processes. Because with SBM, you don't just get any machine - you get the right one right from the start.
Efficient technologies to obtain clean results
The shortage of high-quality material resources often requires the extraction of sand and gravel layers with impurities. SBM offers solutions for the processing of:
- Inorganic impurities such as loam, clay, caking and fine grain attached to the larger particles, which are reamed and washed out.
- Organic impurities such as coal, peat and wood, which are sorted out by processes that make use of the density difference between the materials.
Double-shaft log washers
SBM double-shaft log washers are mainly used to loosen loam but also brittle grain. With the overflow, wood, coal and peat can be removed as well.
Design
- Twin drive with connected and controlled bevel gear motors
- Fixed bearing as ship thrust bearing
- Floating bearing as a generously dimensioned pedestal bearing
- Large distance between logs and trough for low-wear operation
- Trough safety cover
- Upstream device (optional) to remove light materials
Jetting device
With material cascades for primary loosening of the contaminated raw gravel.
Loosening and cleaning by
- High-pressure water jet
- Mechanical load of the material
Dewatering screening machines
For subsequent sand dewatering or as a washing device with spray facilities.
Design with:
- PU-mats
- Unbalance motors
DISC Separator
To reduce fillers and separate light-weight material
- Rotary disc with central discharge
- Counterflow- separation
- Vibration dewatering
Sand traps
To dewater and recover fine sand from solid material-- water suspensions from the underflow of a washing screen or loosening station: discharge of the elutriable particles via water drain; sands (finest sand particles) are discharged by buckets. Vacuum chambers increase the dewatering capacity. With sand traps, the settled solids are transported to the buckets by screws.
DESIGN
- Various trough lengths available to adjust the separating cut to the amount of washing water
- Optimised crusher dewatering by means of vacuum extraction and quick water drainage
- Long overflow edges to ensure smooth and even dirty water drain
- Adjustable overflow edges to optimise the separating cut
- Wear-resistant inlet chamber and material discharge chute
- Fill-level-regulated speed control
Double sand trap
The SBM double sand trap is provided with two independent speed-regulated bucket wheels. Simultaneous use as both sand and fine sand trap allows to produce 0/4 as well as 0/1 in one single operation.
- Possibilities for sand correction
