The knife side chops sticky products. The hammer side is used for crushing hard, crystalline products. In the hammer mill, the particle size is defined by the sieve size selected for the mill. The BTM provides different sieve inserts that can be used to reduce the material size to as little as mm. An application example
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 holes mean higher open area, and therefore increased throughout a performance, reduced specific power requirements, coarser product, a shorter useful lifespan of the sieves.

This article focuses on two widely used types: the hammer mill and the jet mill. Hammer mills are often used for generalpurpose grinding and the finished product particle size ranges from millimeters to tens of microns. The jet mill is primarily used for superfine grinding applications and creates particles sizes down to a few microns.
ABSTRACT: The laboratory size hammer mill was fabricated from locally available materials for crushing of minerals such as calcite, dolomite, limestone, granite and other materials of medium hardness.

A hammer mill is a machine or mill whose purpose is to shred or crush aggregate material into smaller pieces by the repeated blows of little hammers or beaters. A number of ingredients used in making feed for Poultry and other livestock are granular in nature and need to be broken down for further processing.
Adekomaya and Samuel (2014) reported the design of a hammer mill with crushing efficiency of 94% that reduces processing losses and eliminates health hazard experienced by the operator. AlRabadi (2013) investigated the influence of hammer mill screen size on the average particle size, production output and energy consumption of a hammer mill ...
The hammer mill has 32 pieces of swing hammer of × × 120 mm on a 610mm diameter rotor. The tip of the hammers reaches a linear speed of 115 m/s. The air flow rate of the blower is 63 m 3 /min. The total rated power of the hammer mill circuit was 42 kW (Table 1). Several different sized screens were used to investigate their effect ...
This indicated that for the same batch of maize the screen size of the hammer mill (target GMD) affects the nutrient content distribution. Starch content of fractionated maize ranged from to g/kg in the current study, which is higher than results obtained by Acosta et al. (2019) ranging from 556 to 683 g/kg.
