Training Service
WTW service engineers are available to assist all clients with successful installation, start-up and operation of their WTW equipment.
Our trained staff can offer complete maintenance training, review all equipment, and assist operators with routine maintenance programs for their equipment. In most instances WTW equipment operates 24/7 leaving little down time. A routine maintenance program and a better understanding of key maintenance areas, often leads to longer life of all equipment.
Flow & Techniques
Where bulk materials create most of the problems, equipment
must be correctly selected to achieve proper plant layout
and operations. No matter whether the material is cohesive
like filter cake or flue gas desulphurised gypsum (FGD),
contains large pieces such as limestone or coal, is fine,
powdery and free flowing like Fly Ash, or is moist and odor
intensive like Sewage, the layout for the storage, conveying
and reclaim system must be individually matched according to
the characteristics of the bulk material concerned in order
to ensure trouble free plant operation.
Funnel Flow Vs Mass Flow
Funnel Flow occurs when some of the material in your bin
moves while the rest remains stationary. The walls of the
hopper section of your bin are not steep or smooth enough to
overcome the friction that develops between them and your
bulk solid.
Mass Flow
occurs when all the material in your bin is in motion
whenever you discharge the product. The hopper walls
are steep and smooth enough to overcome the friction that
develops between the wall surface and bulk solid, ensuring
mass flow. Since all the material is moving, ratholes
cannot form, making mass flow suitable for cohesive solids,
powders, materials that degrade or spoil, and solids that
segregate.
