The bifurcated chute is one of nine transfer point solutions that is being engineered and manufactured by bulk materials handling transfer solutions provider Weba Chute Systems for Canadian low-cost gold producer Eldorado Gold8217s Hellas Gold Skouries project.
This high-grade gold-copper porphyry deposit is located in northern Greece and will operate as an open pit mine for around seven years followed by a further 20 years of underground development.
Weba Chute Systems technical director Alwin Nienaber says this is not the first time the manufacturer of transfer point solutions has worked at Eldorado Gold operations.

An important contributing factor to this particular project was the extensive communication between the mine the EPCM contractor and Weba Chute Systems which resulted in Weba Chute Systems being able to assess adjust and verify general arrangements between conveying crushing and screening equipment.

Commenting on the design of the bifurcated transfer point Nienaber explains that this particular chute is engineered for the secondary crushing circuit.
The chute feeds either a surge bin which in turn feeds the secondary crushers or it provides a facility whereby the crushers are bypassed.
However among the challenges in this particular application was having to overcome a transfer height of 17.5 m by passing from just below the head pulley through the conveyor building then under the structure over the bin and down to the conveyor and still provide access for crusher maintenance.
Weba Chute Systems recent solution at a diamond mine in Botswana has tackled the issue of large particle sizes to ensure more uptime for the customers operation.
The mine had been faced with replacing transfer chutes almost every three months as they could not withstand the arduous operating conditions. Run-of-mine material with lump sizes up to 1200 mm was fed via an apron feeder onto a grizzly feeder with the oversize material reporting to the jaw crusher.
The large size of the lump kimberlite in this application as well as material being uncontrolled posed an ongoing challenge to the transfer system. Another challenge in this primary circuit was that the conveyor receives material from the grizzly underpan and jaw crusher discharge and lack of material control had resulted in high impact onto the conveyor belt. This damaged the conveyor and caused considerable spillage resulting in unplanned downtime as the conveyor belt had to be replaced just about every quarter according to Weba.
The added expenditure and lost productivity meant increased operating costs for the plant and eventually led to a decision to address the total material transfer system. The technical team from Weba Chute Systems assessed the challenges being faced and in close collaboration with the mine engineered a material handling solution Weba said.
Dewald Tintinger Technical Manager at Weba Chute Systems said Dealing with challenging applications and in particular uncontrolled material flow is something we are known for we are often called in to assist plants where a standard one-size-fits-all solution has proved inadequate to their specific material handling needs.

Belt End Cross Cut Sampler Multotecs belt end cross cut samplers are custom designed for all discharge stream applications and models are available for all conveyor widths between 450 and 2 400 mm Owning to its rugged construction the belt end cross cut sampler is very suitable for export heavy duty sampling applications
Belt Feeders. From a 4-0 long feeder for a roofing shingle manufacture to capture fines overflow to an 84 BW x 60 feeder with a bed depth of 2-0 and a 6-0 long fiberglass section to enable utilizing a tramp metal detector and a discharge chute with integral flop gate for tramp metal rejection weve supplied equipment for a wide variety of applications.
Tintinger said An integral swing mechanism engineered to guide these large lump sizes through the transfer point at a controlled velocity reduces the impact on downstream equipment. The next chute in the process flow therefore no longer has to deal with excessive impact as this has been addressed through the swing mechanism in the first chute. The material then flows through the grizzly discharge chute and reports to the crusher.
The combination of an engineered transfer point with the swing mechanism in this position has drastically reduced high impact and excessive wear previously experienced according to Weba. The chutes longevity has been dramatically improved and has not required replacement since its installation over a year ago.

Fine undersize material washes through the Trommel Screen falls into the Material Distribution Chute and is then washed onto the Concentrator Belt. The Chute can be adjusted to precisely control where material is discharged onto the Concentrator Belt. This allows for additional control of mineral recovery and yield in certain applications.
