There are several new and unique bulk solids
handling demands that have developed in the environmental industry
due to the increased demand for more environmentally friendly
technologies. The materials handled in this industry, such
as soils, tailings, and sludge materials, often have high cohesive
strength, leading to arching (bridging)
and ratholing.
Bulk solids that are shaped like flakes or fibers, such as
ground plastic, shredded tires, or wood chips, can interlock
to form arches, resulting in large masses of non-flowing material.
Flow problems such as these can result in high cost and wasted
time. The key to success in designing reliable equipment for
these difficult-to-handle materials is determining the flow
properties of the materials and using these properties as the
equipment design basis.
Jenike & Johanson helps plants keep bulk solids flowing
reliably while complying with regulatory requirements. We also
give companies a significant competitive advantage by modifying
their bulk solids handling methods to increase process efficiency
and substantially reduce operating costs.
KEY ENGINEERING SERVICES
- Feeding of sewage sludge at treatment and recycling facilities
- Storing and feeding ground tire rubber powder
- Increasing feed rates of flow rate limited materials
- Conveying and feeding of contaminated soils to remediation processes
- Handling fuel addition, e.g., tire chip
In order to formulate an approach to solving or preventing a problem, we
need to learn as much as possible about your application to ensure that
handling problems do not occur with the new equipment.
