Advantages & Benefits: Versatility: sizes up to 125 mm feeds to 2mm product. Handles difficult feeds, including wet and sticky materials. Economical impactor design saves on horsepower and energy use. Needs no screens. Cages are available with two different striking surface options, both of which protect the cage structure:
At 1.1 µm the effective cut diameter (ECD) is a tight size range (approximately 0.9 to 2.0 µm) taken directly from the sixth stage of the Andersen eight-stage impactor. Although the scatter is large, it can be very valuable in analyzing the performance of most high-efficiency scrubbers. Respirable dust ranges from about 1 to 7 µm.
The coal and biomass fuels were ground and sized before co-combustion. The co-ash samples were prepared as follows: biomass was uniformly mixed with coal in the proportion of 0.5:9.5, 1:9, 1.5:8.5 and 2:8, respectively (energy basis), and the fuels were put into a Muffle furnace and heated in air for 30
The three types of crushers most commonly used for crushing CDW materials are the jaw crusher, the impact crusher and the gyratory crusher (Figure 4.4).A jaw crusher consists of two plates, with one oscillating back and forth against the other at a fixed angle (Figure 4.4(a)) and it is the most widely used in primary crushing stages (Behera et al., 2014).

Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing.
A sample pump pulls air through the inlet nozzle of each impactor in the inlet plate. Particles larger than each impactor's 50% cut-point are scrubbed and retained on the porous oiled impaction substrate, while smaller particles continue to the standard 37-mm collection filter for analysis. * U.S. Patent No. 7,073,402 . The Disposable PPI ...
The CPDM also incorporates a cyclone rather than an impactor for more precise cut point of of 4.5 microns, which NIOSH has determined is the most effective cut point for measuring respirable coal dust.
