The SKIOLD Disc Mill® is the result of many years product development and testing, with the object of producing an all-round mill for grinding grain and other crops, with low power consumption, quiet running and minimum dust levels. At the same time the mill should allow automatic adjustment of the degree of grinding during operation to achieve the required fineness and structure of specific feed mixtures for different animal groups or species. The Disc Mill® should also be compact and fit in easily, even with existing plants.

The Grinding Process on a SKIOLD Disc Mill®The grinding process takes place between two discs consisting of a number of segments made of tungsten carbide - the same material used for producing cutting tools in the engineering industry. Quality and product-wise, the SKIOLD Disc Mill® meets all the demands made by today's largest and most professional animal producers as well as commercial feed millers.

The Grinding Wheel on a SKIOLD Disc Mill®When grinding normal cleaned grain, the durability of a set of discs ranges from about 5,000 tonnes for the SK 2500, to 10,000 tonnes for the SK 5000 and up to 20,000 tonnes for the PROF 10T, considerably increasing service intervals.

Since each of the SKIOLD Disc Mill® motors are mounted directly on one of the grinding discs, power is used very efficiently in the grinding process. Since the process operates without air, dust emissions are virtually eliminated. Noise levels are an amazingly low 80 dB which is considered quiet running compared to a traditional hammer mill with a noise level between 85 - 90 dB(A).

Feed structure is determined by the required ration, and it is therefore important to be able to control fineness and grinding degree. This is carried out be adjusting the distance between the discs, an operation that is performed either manually, by means of a handle on the front of the mill, or automatically via an actuator controlled directly by the control system of the plant.

By virtue of its compact appearance the SKIOLD Disc Mill® fits easily in both new and existing plants.

Even though each mill is fitted with a strong labyrinth magnet as standard, Danagri-3S recommends the use of a Screen Cleaner as an insurance policy against damage to your Disc Mill due to stones, metal and other foreign bodies which can severely damage the equipment and result in down time periods for repair.

Capacities for the SKIOLD SK 2500, SK 5000 and PROF 10T Disc Mills®
(Capacity depends on raw material quality, moisture content, and grinding fineness. The indicated capacities were measured in cleaned raw materials with a moisture content of 13-14%.)

HAMMER MILLS
Danagri-3S offers a comprehensive range of hammer mills from SKIOLD to complement any mill and mix system and for any livestock enterprise.

SKIOLD Hammer Mills from Danagri-3SSKIOLD Hammer Mills are ideally suited to grinding ingredients for animal feed and are supplied complete with built-in fans which have the added advantage of cooling the meal in the process. The simple but robust construction of the mill enables it to be accommodated into most existing systems.

The hammers are made of hardened spring steel with a great wear resistance. All the hammers in a set are weighted so that the mill does not vibrate during operation. The hammers are reversible up to 4 times to increase durability.

A comprehensive range of replacement parts is available for all SKIOLD hammer mills, including hammers, screens, fan wings and protection covers. Added to this, a large range of accessories is available to give greater flexibility and adaptability into the SKIOLD range of mixers, proportioners and many other existing systems (see below).

Three models are available in the range: the DM-2, the DM-3 and the BM-5.

Type DM-2
This is supplied with either a 5.5 or 7.5 kW motor with a capacity of up to 500 kg/hr, a conveying capacity of up to 70 metres and a daily consumption of up to 2 tonnes.

Type DM-3
The DM-3 is supplied with either a 11, 15 or 18.5 kW motor with a capacity of up to 1300 kg/hr, a conveying capacity of up to 80 metres and a daily consumption of up to 5 tonnes. The DM-3 is also available in the Prof-Line version which have more durable parts.

Type BM-5
The BM-5 is the biggest in the range and is equipped with either a 30 or 37 kW motor with a capacity of up to 2.5 tonnes/hr, but the conveying capacity is limited to up to 30 metres.

The Prof-Line version of the SKIOLD DM-3 Hammer Mill from Danagri-3SPROF-LINE DM-3

The Prof-Line is a specially adapted version of the DM-3. The construction of this mill includes the use of wearing parts that have been specifically made to give extra long durability compared to the normal DM-3.

The mill is characterized by its large, conical suction hopper, which distributes the material more evenly over the hammer rotor therefore prolonging its lifetime. A complete Prof-Line set is available for remounting on the standard DM-3 mills.

ACCESSORIES
Cyclone and Filter
With air conveying, a cyclone is necessary to separate feed from air. Cyclones are adapted to the various mill types in order to obtain maximum separation. The air outlet of the cyclone is equipped with a filter for collecting fine dust. Alternatively, the air can be discharged into the open with with a rain cap fitted.

Feeding Device
The material is sucked into the mill through a feeding device which, for safety reasons is fitted with a magnet to catch possible iron parts in the grain. Feeding devices are available in lengths of 0.5, 1.0 and 2.0 metres. They can be mounted directly on the silo outlets.

Stone Trap
In order to protect the mill against damage, a stone trap is always mounted in the suction pipe. The stone trap separates all that is heavier than the grain, and a special device takes care that the stone trap is emptied automatically.

Ducting
A full range of ducting and accessories are available for each size of mill.

Booster Fan
In plants where the mill's own fan is not sufficient, a booster fan can be built into the system to increase conveying capacity by up to 150 m. The fan is built into the mill blowing line and does not increase the air quantity, but only the pressure in the system. The fan can be placed anywhere in the fan pipe of the mill, but there must be a minimum of 2 metres of straight pipe on the inlet and outlet of the fan, before a bend is placed. A special electrical panel, connected to the mill controller, operates the booster fan.
