Keoghs - Silo Unloaders

Flat bottom Silos are an effective and efficient solution for large volume commodity storage, Keoghs purpose built range of silo unloaders are ideal for reclaiming these stored products. In an industry where experience and quality do matter Keoghs is the undisputed leader. We manufacture 2 main types of unloaders, the first is the agricultural silo unloader which is marketed towards farmers who unload their silos on average less than 5 times per year. Continuing on from the agricultural grade machine is the commercial silo unloader which is targeted at large grain stores and those requiring serious grain handling. Both types come in a multitude of different drive types, lengths and angles to suit almost any imaginable configuration, when requested we can fully customize our silo unloaders to suit any size silo. But when creating a new storage site we recommend using major silo suppliers such as either Kotzur or Cyclone Silos, as our standard line of products compliment there silo lines perfectly. Our unloaders are capable of handling all grain types and come fully sealed for silo gassing.


Keogh Ag Silo Unloaders
 
The Agricultural Silo Unloader is by far the most popular choice when it comes to a quality silo unloader that enables fast and reliable operation with a class leading long life span. This long life span is due to Keoghs renowned  extra heavy construction, which includes standard items such as 3 mm thick tube, 3.5 mm thick flite, 6 mm thick flite at the incline pick up and all external metal items are hot dip galvanized. Our agricultural silo unloaders come in a range of barrel diameters from 200 mm up to 350 mm (see the chart below for further details)and can be ordered in a variety of drive types. A popular choice are our electric/electric models, this unit uses 2 separate electric motors with the sweep motor located in the center of the silo being D.I.P. rated which is required for areas that are prone to explosive dust. If you would prefer to run your new Hawk agricultural unloader off your tractor or hydraulic power pack you can either order a hydraulic/hydraulic unit or a PTO/hydraulic unit. In both cases the sweep is driven by a hydraulic motor in the center of the silo,  the PTO/hydraulic unit has a gearbox that drives the subfloor whilst the hydraulic/hydraulic unit has another hydraulic motor to drive the subfloor. It is also possible to remove both the incline head and sweep to transfer them to other silos that are fitted with the same subfloor. For more Hawk agricultural silo unloader specifications please see the below specifications list.

Based around  a 'U' trough design that allows for periodic 100% loading Keoghs commercial unloaders will move all grain types efficiently out of your silo. Keoghs supply an electric/electric version of our unloaders which has become increasingly popular due to the D.I.P rated motor located inside the silo which gives dependable service. Other drive types include electric/clutch (electric drive to the subfloor and to the sweep via a clutch system) and PTO/clutch (PTO power to the subfloor and to the sweep via a clutch system).
