The Antares roller mill comes in two designs – the four-roller mill MDDR and the eight-roller mill MDDT. Roller lengths range from 600 mm to 1500 mm, with two diameters – 250 mm or 300 mm. You can add various options including automatic grinding gap adjustment, roller and bearing temperature monitoring, water cooling and direct suction.
Machine-grooved rollers are available in steel or chrome and can be inexpensively re-machined up to three times if damaged or worn. An optional magnet removes nails and other metal objects from the grain and prevents …
Vertical roller mill is suitable for the large-scale processing of non-metallic mineral powders below 1250 mesh. Its large-scale and energy-saving effects are significant. ... If the pressure is too small, effective grinding cannot be achieved, resulting in low powder yield and low production capacity. Excessive pressure may lead to instability ...
4.2.3.1.1 Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.
With the single-roller mills, brittle, soft to medium-hard materials can be reduced in size with a reduction ratio of approx. 1:5 to 1:5. The stepped arrangement of the crushing jaws on the crushing wall enables any material rolling off being …
In the case of a mill stop, the material being rolled can remain in contact with the work rolls for a considerable time. The temperature of the roll surface increases rapidly in the contact area and heat penetrates deeper into …
Automatic grinding gap adjustment. The grinding gap on our roller mills can be adjusted manually or, on some models, automatically. If you adjust the grinding gap automatically, the adjustment can be based on your recipe or on particle size. This enables you to produce a consistent and high quality of flour and semolina.
