#The full range
From silo to discharge, one continuous line.
From silo to discharge, Cosben builds every stage in between: storage discharge, conveying, feeding, mixing, valves, filtration, fluidisation and the spares that keep them running. Buy one machine or the whole line, with a single manufacturer.
Screw flights and conveyor bodies are fabricated in-house in Mumbai, India.
For every stage from the silo to the discharge.
Each family of products below handles one stage of the manufacturing line, meaning the handshake points are designed by one team instead of many negotiations from multiple suppliers.
Conveying & Feeding Equipment
05 Products
Inclined Tubular Screw Conveyor / Feeder
Enclosed tubular screw for lifting powder at an angle without spillage or dust escape.
Cement Screw Conveyor
Long-throw tubular screw sized for cement, fly ash and other fine abrasive powders.
Trough Screw Conveyor
Open U-trough screw with a bolted cover, for free-flowing material and easy inspection.
Discharging Equipment
06 Products
Automatic Bag Slitting Machine
Cuts, empties and compacts sacks automatically, typically 400 bags/hour on 50 kg cement.
Bag Dumping Station
Operator-height dumping hood with integral dust extraction and a discharge screw.
Loading Bellow
Retractable telescopic chute for loading tankers and open trucks with the dust contained.
Feeder Equipment
03 Products
Loss in Weight Feeder
Gravimetric feeder that doses by weight loss per second, for accurate continuous addition.
Micro Batch Feeder
Small-dose feeder for pigments, additives and minor ingredients in the grams-per-batch range.
Mixing / Conditioning Equipment
03 Products
Plough Share Mixer
Ploughshare blades throw material into a fluidised bed, fast, uniform, low shear.
Dust Conditioner
Wets and conditions collected dust so it can be handled and disposed of without re-dusting.
Valves / Silo Accessories
06 Products
Pressure Relief Valve
Protects the silo shell from over-pressure and vacuum during pneumatic filling.
Safe Venting PRV
Relief valve that vents downward and filters the escaping air, so nothing is released at height.
Filters & Dust Collectors
06 Products
Top Mounted Dust Collector (Vibratory Type)
Silo-top filter with mechanical shaker cleaning, no compressed air needed.
Ground Mounted Dust Collector (Vibratory Type)
Same shaker cleaning, mounted at ground level where the silo top is not accessible.
Top Mounted Dust Collector (Reverse Air Jet Type)
Silo-top filter with pulse-jet cleaning for continuous, high dust-load filling.
Ground Mounted Dust Collector (Reverse Air Jet Type)
Pulse-jet filter at ground level, with the hopper and rotary discharge below.
Silo / Bin Mounted Dust Collector (Reverse Air Jet Type)
Pulse-jet bin filter that sits directly on the bin it vents.
Fluidization / Vibrators
03 Products
Electrical Vibrator
External motor vibrator for hoppers, chutes and screens where power is available.
Spare Parts for Silo Accessories

Nothing in this range has a standard size.
Every machine here is built to the material and the duty. The same 350 mm screw is a different machine in fly ash than it is in foundry sand, a different flight thickness, a different facing against abrasive material and a different bearing choice.
