Investigation of breakage characteristics of low rank coals in

2014年4月1日  The breakage characteristics of low rank coals by hammer mill (HM) were investigated. • There exists a feed rate threshold above which over-grinding occurs. • A scale-up model of the hammer mill is established based on the energy-size relation. • The model based on Rittinger's theory fits the HM breakage characteristics best. •

Grinding in Ball Mills: Modeling and Process Control

There are three types of grinding media that are commonly used in ball mills: • steel and other metal balls; • metal cylindrical bodies called cylpebs; • ceramic balls with regular or high density. Steel and other metal balls are the most frequently used grinding media with sizes of the balls ranging from 10 to 150 mm in diameter [30].

The kinetics of hammer milling of maize - ScienceDirect

1976年5月1日  The kinetics of breakage of maize were measured in a small laboratory hammer mill, with a rigid blade used as hammer. It was found that breakage was first-order, and that the primary breakage distributions were insensitive to mill conditions or moisture content of the material. The specific rates of breakage were dependent on particle size to ...

Direct mechanical energy measures of hammer mill

2009年7月10日  Cadoche and López [20] tested knife and hammer mills on hardwood chips, agricultural straw and corn stover. Effective specific energy demand to reduce hardwood chips to a particle size of 1.6 mm was 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
