Jan 01, 2010 Measuring the energy requirement for alfalfa size reduction could be important for downstream processes such as densification. 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

Apr 01, 2013 In order to further reduce energy consumption and to spare the environment, UFA continuously adapts its feed mills to the latest technological knowledge. For example, over the past 10 years about 5 percent electrical energy and 17 percent thermal energy per metric ton of animal feed produced have been conserved, while at the same time

Compared to conventional, straight forward hammermilling, these new hybrid arrangements can reduce power consumption by around 15%, which cannot be ignored in these stringent times. The key to successful size reduction, however, is diligence and, as with all aspects of mill management, attention to detail is paramount

Hammer mills use large rotating drums with protruding metal bars (i.e., hammers) that impact the material at high veloc - ity to shatter and tear material particles. Typically, the metal bars swing freely from the drum, but fixed hammers are also common in hammer mill designs. Hammer mills are recognized as technology capable

Optimal hammer design and placement will provide maximum contact with the feed ingredient. Hammer mills in which the rotor speed is approximately 1,800 rpm, should be using hammers which are around 25cm (~ 10 inches) long, 6.35cm (~2.5 inches) wide, and 6.4mm (0.25 inches) thick. For a rotor speed of about 3,600 rpm, hammers should be 15 to 20
