ABC Hansen Africa has developed as part of our feed milling equipment range, a simple, yet high capacity range of feed milling systems, that we call the Mini Feed Mill.
The Mini Feed Mill allows for a producer to be able to buy the core equipment of a feed mill, working in a continuous process, to minimize initial capital investment, while not giving up capacity or feed quality.
The Mini Feed Mill is able to process nearly the entire range of feeds, including poultry, ruminant and pig feeds – in either mash form, or in pelleted form – either as concentrates, licks or as whole rations.
The Mini Feed Mill is supplied in two basic capacities – 750kg per hour and 1500kg per hour. Though we call it the Mini Feed Mill, the capacities are actually quite significant – for example – by running the 1500kg/hr mill for a mere 8 hours a day, you would be able to produce 12 tons of feed per day – which translates into enough feed for a broiler poultry farm of 170,000 birds (at an average consumption of 70 grams of feed per day). Not so mini at all, or translated into a full ration for a small feedlot – it would be enough for 950 heads of cattle (at an average consumption of 12.5kg per day).
Using the proven Hippo Hammer mill and the ABC Hansen Contraflow Horizontal Paddle mixers, ensures a homogenous sized and mixed final product, for optimal utilization by livestock
The Mini Feed mill system provides you with all the core components of a feed mill, being milling, mixing and pelleting of your ration, and the mill can be upgraded with time, to incorporate more automation in the batching and weighing process to ensure repeatable results in the process.
The Mini Feed Mill process is a simply one – and we’ll run through it for you.
-Rations are weighed off before milling in the correct quantities – using a platform scale – making up a batch of either 500kg(for the 1500kg/hr system) or 250kg(for the 750kg/hr system) – which is equal to the capacity of the horizontal paddle mixer
-The ration is then fed through the hammermill, which then mills all the components to a homogenous size, and then deposits the milled ration into a batching bin – using its intetgrated air transport and dust control system – that Hippo Mills are famous for.
-The hopper bin (which can be mounted on load cells with a LCD indicator) is also fitted with a vibration motor, to ensure that the ration doesn’t bridge in the hopper bin – especially for rations high in roughage)
-The hopper bin is unloaded with an auger directly into the Contraflow Horizontal Paddle mixer, where the ration is then mixed for between 3 and 5 minuts. After mixing is completed, the blender slide is opened, and the mixed ration is discharged with an auger into a second bin – called the post blending bin.
-Depending on whether you choose to pellet the feed, or to just produce mash feed – the post blending bin will either discharge at a controlled speed (using a variable frequency drive) into the pellet mill(when making pellets), or directly into bags (when producing mash)
-Because the pellet mill is mounted on HDPE wheels, it can be easily moved out of the way, and a bagging attachment fitted to the post blending bin unload auger, for quick switches between producing mash or pellets.
When producing pellets, the size of the pellets can be adjusted by changing the pressing die in the mill. Pellet sizes available are Ø2.5mm/ Ø4mm/ Ø6mm/ Ø8mm/ Ø10mm – the size selection would depend on the type of feed and type of animal being produced. Ø2.5mm and Ø4mm are favoured in poultry feeds, while Ø6mm and Ø8mm are favored for sheep, goats and cattle. Ø10mm is usually favored by producers of game pellets, as the pellet size is still small enough for most antelope to eat, while it is too big for guinea fowl to easily handle – reducing losses from birds.
After the feed has been pelleted, it is then collected by a bucket elevator, and discharged into a cooling unit, where the pellets are cooled from the exit temperature of the feed mill of between 50ºC and 60 ºC to ambient temperature – which allows for the pellet to quickly cool, and the drying off of condensed moisture that collects on the pellets, and thus result in harder, better quality pellets.
