Description:

Crowley hoppers are of a sturdy high quality fully galvanised steel construction. Hoppers are smooth-walled, circular cross section therefore ensuring good flow of feed without the trapping effect of corrugated sections. The hoppers are constructed from heavy gauge (1.6 to 2mm) galvanised steel sheets, with the steel support structure from heavy gauge hop-dip galvanised steel sections. All hopers are fitted with a comprehensive set of stiffeners to prevent deformation during the load/unload cycle. Stainless steel nuts and bolts are used throughout the hopper. This gives our hoppers a low maintenance lifespan of around 30 years when correctly cared for.

 

All silos are supplied as standard with a 4” dia. blow & 6” dia. exhaust pipes, and also feed level sight glasses. Hoppers come in plain galvanized finish but for personal preference or local authority planning requirements, bulk feed bins can be sprayed in a range of landscape blending colours.

 

A range of extra equipment is available for the hoppers to suit almost every requirement, in addition to this, non-standard equipment can be manufactured to meet one-off individual requirements.

 

 Hoppers are delivered, tipped upright and secured to the ground using our specialized hopper transport.

 

Ventilation System:

All feed silos are fitted as standard with an exhaust pipe to allow air to escape from the hopper during filling without leaving dust of the roof. Where high moisture content feeds are to be stored roof mounted moist air ventilators to regulate the hoppers internal atmosphere are available. These incorporate an anti-dust valve, which automatically shuts during filling to prevent dust venting onto the hopper roof. Once filling is complete the valve opens to allow moist air to vent therefore preventing condensation.

·          Side & roof ladders

·          Bag-off chute

·          Additional sight glasses
