Milling and Mixing SystemsOnly from Big Dutchman Skandinavien
for the production of feed mixes from home-grown cereals
The trend is increasing towards using home-grown cereals for the production of mixed feed. This permits the farmer to produce individual feed mixes of known quality, saves transport costs and makes for more flexibility. Big Dutchman can offer you the respective technology:
- hammer mills with a throughput of 1.5 to 15 t/h
- different dry mixers (vertical, horizontal)
- silos for indoor and outdoor use in different sizes for grain storage, storage of additional raw materials and of the finished mixed feed
- containers for premixes and micro ingredients
- pelleting equipment.
for evenly-structured feed
The Big Dutchman hammer mills operate with a driving power of 11 - 110 kW. Depending on the requirements, for example fine grinding or feed with more structure, different mills and screens are used. The special milling control system ensures that the dosing auger supplies the mill with the type of material that is to be milled. This means the delivery rate is automatically adapted to the type of material to be conveyed.
The ground meal can be transported by means of different conveyor elements (bucket or chain conveyors or trough augers). The type of mill installed (single, double or parallel mill) depends on the throughput requirements. Certain conditions might require the installation of a parallel mill instead of a large single mill. This way different recipes or different particle sizes of feed can be produced much faster.
- high capacity (up to 15 t/h);
- even feed structure;
- mill grinds in both directions → even wear of the screens;
- screen cleaner and metal collector for high performance and a longer service life of the mill;
- rugged construction;
- dust filter for better hygiene;
- designed for easy maintenance;
- all parts of the mill are mounted onto a frame which minimises the installation requirements on site.
high mixing accuracy, versatile use
The vertical and horizontal mixers offered by Big Dutchman can be used to mix different ingredients such as cereals, soya, dry minerals, vitamins and fats together to produce high quality feed mixes. Both large amounts and small amounts can be mixed with a high mixing accuracy.
Advantages of the vertical mixer
- massive, vertical mixing screw;
- compact design, made of steel → requires only little space and is very rugged;
- the screw can be reached by means of a cleaning hatch;
- operation surveillance via an inspection window.
Advantages of the horizontal mixer
- double, counter-rotating steel screw along the entire length of the mixer
-> high mixing accuracy (1:100 000)
-> very good mixing quality, including small amounts
-> low wear; 4 short mixing times;
- 3 or 4-leg, weighed batch mixer → precise weighing;
- residue-free emptying;
- maintenance-friendly cleaning opening for better hygiene;
- mixing of CCM is also possible.
Silos for indoor and outdoor use
for storage of primary ingredients and finished feed mixes
Big Dutchman can offer their customers a variety of silos made from different materials and in different sizes for safe storage of ingredients and of finished feed mixes. The number and size of the silos are planned according to the individual requirements on a farm. For slow-flowing materials there are special auger silos available.
Hoppers for minerals and premixes
for storage of small amounts
Different types of hoppers are available for premixes and other additives.
- hopper T 100 for 0.5 m3
- hopper T 160 for 0.65 m3
- hopper with agitator for 0.45 m3 ; for slow-flowing premixes.
Other sizes are available on request. The transport of the additives from the hopper to the mixer can be done by means of augers (Ø 102 mm) or spirals (Ø 75 mm). If a hopper with agitator is used, the material is exclusively transported by means of augers (Ø 102 mm).
for pelleting of finished feed mixes
If the mixed feed is not to be supplied as meal but as pellets, Big Dutchman can also supply the respective technology.
The pelleting equipment comprises the actual pellet press which is preceded by a hopper for the meal-type feed. The feed is transported from the hopper to the conditioner by means of a frequency-regulated dosing auger. In the conditioner the feed is treated with hot steam to facilitate pressing and for better hygiene (by reducing salmonella and bacteriae). From there, the feed is transported to the actual press. The press itself is a rugged, low-maintenance ringdie press.
A cooler installed downstream ensures that the pellets can be stored stable and safe in a silo. The dimensioning of the pelleting equipment depends on different factors, among others this includes which type of ingredients are used and for which type of animal the feed is being produced.
