HOG FUEL

Hog fuel or wood waste is among the most difficult flowing materials. It is stringy and easily compactable. Also, the consistency of hog fuel is often quite variable. The net result is a material that is unforgiving, where poor bin and feeder design will lead to permanent, chronic bridging and plugging.

The Kamengo Feeder has been relied upon for numerous hog fuel boiler feed, pile reclaim as well as day bin applications. The first Kamengo Feeder for hog fuel went into service in 1993, and has been operating reliably since.


WOOD CHIPS

Wood chips is a low density material that requires a wide bin opening and a fully live bin to achieve reliable material flow without risk of hang-ups. This scenario is challenging to achieve with conventional feeders, but is easy to achieve with a Kamengo Feeder. As a result, the Kamengo Feeder is ideally suited for feeding chips from silos/tall storage, feeding chips through steaming bins, and loading chips into trucks.

A Kamengo designed bin and Feeder installed in 1995 demonstrated that a Kamengo Feeder could load 14-25% more chips in a truck trailer before it volumed-out as compared to a truck loaded using a more conventional method.


CORN FIBER

Corn fiber is a very difficult flowing material, in particular when wet. Corn fiber’s flow characteristics demand a wide feeder and a fully-live bin.

A Kamengo Feeder installed in 2008 is being used to feed wet corn fiber from a 67.5 foot tall bin.


PROCESSED WOOD PULP

Processed wood pulp (or crumb pulp) is a fibrous, low-density, high moisture-content (+60%), highly-compactible material that is able to bridge over large bin openings.

A 6,000 cu-ft mass flow bin and Kamengo Feeder installed in 2004 is being used to store and discharge processed wood pulp into 45-foot truck trailers.

ORE CONCENTRATES


COBALT HYDROXIDE

Cobalt hydroxide is a sticky, cohesive unforgiving material.

Four Kamengo Feeders in operation are discharging cobalt hydroxide from plane from hoppers at one of the largest copper mines in the world in the Democratic Republic of the Congo. Two of the feeders receive material directly from a filter press, making the material particularly cohesive and difficult flowing.

GYPSUM


ROCK GYPSUM

Gypsum is a sticky, cohesive material that is particularly difficult to handle when wet. When compacted, gypsum can gain a concrete-like strength. The net result is a material that is unforgiving, where poor bin and feeder design will lead to permanent, chronic bridging and plugging.

In service are two self-unloading ships for transporting raw gypsum. Each ship is fitted nine 100-foot long Kamengo Feeders. The first ship went into operation in 2002.


SYNTHETIC (FGD) GYPSUM

Synthetic (FGD) Gypsum is a sticky, cohesive material that is particularly difficult to handle when wet. When compacted, gypsum can gain a concrete-like strength.

In service are two mass-flow hoppers and Kamengo Feeders storing and feeding FGD gypsum in arctic conditions in Northern Alberta. Also, two Kamengo Feeders for handling FGD gypsum were installed in 2002. Each of these feeders discharged FGD gypsum from a 36.5-foot long discharge opening below a 55-foot tall silo.


RECYCLED GYPSUM

Recycle gypsum consists of waste board that is typically crushed, screened and re-introduced into the gypsum board manufacturing process. The material can have a high moisture content from being stored outside.

In service are two front-end loaded hoppers and Kamengo Feeders being used to discharge recycled gypsum. The first installation was put into service in 1995, and continues to provide reliable service. The Feeder is able to deliver a consistent metered stream of material at even the low discharge rate required by the board manufacturing process.

FINE, COHESIVE & ABRASIVE MATERIALS


WET BOTTOM ASH

Bottom ash is cohesive and abrasive. For a coal-fired power plant in Australia, Kamengo supplied a feeder to handle wet bottom ash.


WET AND DRY FLY ASH

Fly ash is fine and light, and will de-aerate, allowing it to compact and significantly gain in strength. It can also be quite dusty. Kamengo has delivered minimum water solutions where fly ash is stored dry in a dust-controlled bin and then smartly conditioned as it is discharged.


ROCK PHOSPHATE

A Kamengo Feeder handling rock phosphate has been in operation in Edmonton, Alberta since 2001.

FINE, COHESIVE MATERIALS


GRAIN SCREENINGS

Grain screenings are a fine material that aerates and will pack quickly forming hang-ups.

The first commercial Kamengo Feeder in operation was installed in 1988 in Vancouver, Canada under a 100-foot tall silo containing up to 1,200 tons of stored grain screenings. The Feeder is powered by a simple air cylinder.


FLAKED CORN

An improperly designed bin and feeder handling flaked corn will suffer from unreliable, difficult to control material flow. In 1999, Kamengo retrofitted a 15-foot diameter corn silo at a brewery in Vancouver, Canada. The silo was producing erratic and unreliable flow. The silo’s slope and outlet dimension did not exceed the stored material’s piping dimension. As a result, the stored flaked corn would stagnate along the bin walls causing hang-ups. After the retrofit, the silo could be discharged in an even controlled manner without plug-ups, allowing the plant to operate at optimum capacity.

PELLETS


CANOLA PELLETS

Because the Kamengo Feeder relies on gravity and proper hopper design instead of brute force to discharge material, the Kamengo Feeder is a very gentle feeder ideal for handling pellets. It is expensive if a pellet plant’s reclaim feeder chews up its product.

In 2009, Kamengo delivered three 37-feet long feeders, each feeding canola pellets from a 130-feet high, 42-foot diameter silo.
