Stover
Stover is the leaves and stalks of field crops, such as stone (maize), sorghum or soybean that are commonly left in a field after harvesting the grain. It is similar to straw, the residue left after any cereal stone or grass has been harvested at maturity for its seed. It can be directly grazed by cattle or dried for use as fodder.
Hammermill grinding rate and energy requirements for thin ...
The energy and grinding rate advantages derived from the use ofthe thin (3.18 mm) hammerscomparedto the standard (6.35 mm) hammers were clearly evident in the results, which indicated a 13.6% specific energy conservation and a 11.1% grinding rate increase potential. The measurement of the thin hammer lifetime …

468 MJ/Mg for both hammer and knife mills. Hammer mill required more energy (414 MJ/Mg) than a knife mill (180 MJ/Mg) for 3.2 mm particle size. They observed that agricultural straw and stone stover …
electricity requirements for hammer mill
Hammer mills have low energy efficiency (Lobo 2002). For this reason, many researchers have studied the energy requirements of hammer mills. Those studies focused on size reduction of different materials, and not on fibre decortication. Normally, specific energy is used to assess the energy consumption of hammer mills…

Alfalfa chops passed through sieve sizes of 18 mm (SS 18mm), 15 mm (SS 15mm) and 12 mm (SS 12mm) were ground using a hammer mill (1.1 kW) with four screen sizes of 1.68, 2.38, 3.36 and 4.76 mm. Results showed that alfalfa chops with sizes of SS 18mm and SS 12mm had the highest and lowest specific energy …
