New transfer point technology eliminates dust in conveyor systems

Cleveland Cascades Ltd designs and manufactures handling
systems for dry bulk materials and has extensive practical
experience handling a wide range of dry bulk products.
Recently the company has introduced an entirely new transfer
point concept which is designed to eliminate dust production,
spillage and the degradation or segregation of materials during
handling. Based on the proven Cleveland Cascade loading chute
technology, the system is so effective that expensive, highmaintenance
energy consuming dust extraction and filtration
systems are not required and spillage problems are avoided. The
system is fully self-contained and no additional containment
structure is required as with conventional transfer points.
Material fed from the delivery conveyor enters the headchute
section of the transfer point from where it is directed to flow
into the deflector section. In the deflector section the material
flows downwards over a series of inclined deflector plates. This
action controls the materials’ speed of descent and ensures the
material travels in mass flow without entrainment of air.
The angles of the inclined deflector plates can be adjusted to
optimize performance of the transfer point even when different
materials and flow rates must be accommodated; this can be
performed remotely from an operator’s position if required.
Where reception and delivery conveyors are set at an angle
to one another, each deflector plate is partially rotated in order
to gradually redirect the material flow into the correct
orientation whilst eliminating material degradation and dust
production.
In the TaperFlow® section material is placed gently onto the
reception conveyor in the direction of travel minimizing impact
damage, belt abrasion and reducing the need for impact sections.
The TaperFlow® skirt less delivery section further controls
dust production and helps ensure that material is placed
uniformly on the belt thus eliminating the need for skirting
systems which historically have been a major source of issues
associated with belt tracking and ongoing maintenance costs.
To accommodate inevitable surges in the amount of material
flowing through the transfer point, the surge capacity section has
the capacity to retain excess material without spillage until it can
be dispersed to the reception conveyor through the TaperFlow®
delivery section.
The Cleveland Cascade transfer point is available in a range of
diameters selected to suit the volume and characteristics of the
material being handled, typically between 40 and 6,000m3/hr.
The Cleveland Cascade series of transfer point designs has
been developed using the latest dynamic modelling technology to
achieve superior material handling performance incorporating
mass flow techniques. This helps to ensure reduced
housekeeping and maintenance costs whilst promoting dust
controlled operation, spillage elimination and reduction in
material degradation or segregation.
Further benefits include compliance with environmental
protection standards and the ability to demonstrate adoption of
best practice in minimizing environmental pollution.
The Cleveland Cascade transfer point is one of a family of
systems produced by Cleveland Cascades Ltd for producers and
