High-quality feed requires high-quality grinding
This is where the crushing roller mill comes into play. As a crushing machine, it has always been used to grind grain and legumes such as maize, wheat, barley, rye and
drives with energy recovery. It has been developed by the company AMANDUS KAHL, an expert in the construction of machines and plants for the compound feed industry. "Animal welfare in connection with animal nutrition has been a key issue at AMANDUS KAHL for years," explains Felix Tometten, animal nutritionist at KAHL.
"Our
crushing roller mill revolutionises feed production in that manufacturers have even more infl uence on the grinding result owing to fl exible setting options. Thus they are able to adapt the recipes to a wide variety of their customers' requirements. This is a huge advantage in terms of animal health."
oats, but also soybeans, rapeseed, lupins, peas and fi eld beans. As an alternative to the hammer mill, the crushing roller mill is suitable for the production of somewhat coarser feed rather than for fi ne grinding. This is achieved by two counter-rotating, corrugated rollers that break up the respective grain into small particles. For this to be possible, the rollers rotate at different speeds so that the desired cutting effect is produced as a result of pressure and shear stress between the sharp cutting edge and the non-cutting edge. The energy consumption is signifi cantly lower than that of the hammer mill. Furthermore, the machine is equipped with very few wear parts and therefore requires very little maintenance and is highly reliable.
For rollers with a diameter of 400 millimetres and a length of 1,500 or 2,000 millimetres, the throughput per hour is around 20 to 80 tonnes. Moreover, the compact machine is characterised by low power requirements and smooth operation. The technology is suitable both for individual components and for mixed products, especially for laying hen feed and other poultry feed as well as for pig feed.
Functioning and technical parameters
The individual drive increases the fl exibility in feed production
The new version of the crushing roller mill is a novelty on the market. It is no longer equipped with the traditional central drive, but with frequency-controlled individual
The new drive design has a particular advantage over the reduction gear previously used. In addition to the size of the grinding gap, the speeds of the two counter-rotating, corrugated rollers made of surface-hardened special steel can now be adjusted individually - even during operation. This infl uences the so-called lead, which denotes the speed difference of the rollers. The lower the differential speed, the lower the fi nes content in the fi nal product and vice versa. The speed ratios can also be reversed if required, which infl uences the resulting structures. Further options are the different corrugations that can be refl uted up to eight times, depending on the product to be crushed, as well as the option of single-stage or two-stage crushing. In the case of two-stage crushing, two pairs of rollers are arranged on top of each other.
