Hammer mills High-performance grinding
The hammer mills are fed radially for dual-rotational operation to achieve uniform wear and full utilization of screens and hammers. Models with tangential inlets are available for low-density products. The hammer mills have a directly coupled mo-tor mounted on a base frame. The front doors are bottom-hinged and open on sliding rails.

of 60g/min and 100g/min while the hammers are rotated at 600rpm and 1140 rpm. The hammer-wall clearance is kept constant at 2.9mm. Mean particle size for all samples at different time intervals were measured. As depicted in Figure 1a and Figure 1b a lower feed rate produced a smaller size distribution at the given impeller speeds.

Hammer mill: parameters that affects grinding
Sieves configuration: The sieves (or screens) of the hammer mills are usually perforated steel sheets of 2 - 3 mm. thickness, with holes whose diameter is usually equal to or less than the diameter of the pellet.Larger holes mean higher open area, and therefore increased throughout a performance, reduced specific power requirements, coarser product, a shorter useful lifespan of the sieves.

Performance Evaluation of a Locally Fabricated
ABSTRACTA bone-crusher ( Haminrrer Mill ) was designed, constructed and tested. The machine was designed to crush 1000kg of bones in one hour. The motor operating speed employed is 2920rpm, the sieve hole diameters are 7mm and 5mm while the numbers of hammers are 12 and 18 'pieces. The performance tests show that the mill is capable of crushing between 860 to I l70kg within an hour.
