the step screen has the highest hydraulic capacity of any fine screen due to its larger open surface area when compared to any other fine screen technology. step screens are available with either 3mm or 2mm thick movable and 3mm or 2mm fixed lamellas. for the 2mm option, the open surface area for a clean screen is 75% (3mm thick lamellas = 60%).

flat screen or disc designs were subject to “plastering” or bridging of solids across the screen. screen wear against bottom grit was problematic. also, solids tend to get trapped within the screen center. solids could also bypass the grinder altogether as these units have no way to assure that the solids don’t escape in the gap between the screen and the grinder.

coarse screens remove large solids, rags, and debris from wastewater, and typically have openings of 6 mm (0.25 in) or larger. types of coarse screens include mechanically and manually cleaned bar screens, including trash racks. table 1 describes the various types of coarse screens. fine screens fine screens are typically used to remove material

place in ball, pebble or rod mills. the efficiency of wet grinding can be higher than that for dry grinding, but wear of equipment is also higher. usually, some form of separation follows size reduction. the most common is simple screening, in which the screen openings are selected to pass the desired size range and retain material that is too large.



the grinding track. grinding ball is inserted, the upper rotating part is loaded and the grinder drive is started up. after 60 rotations the grinder stops and the ground coal is screened for 10 minutes on the screen with square openings with eye length of 0.075 mm. after that grains caught at the bottom of the screen are removed by

screening: in its simplest configuration, a screen is a hard perforated surface with a matrix of fixed dimension apertures. the material is presented to the screen surface so that material finer than the apertures falls through the screen and the oversize is conveyed to the discharge end of the screen.

impact grinding is most efficient with dry, low-fat ingredients, although many other materials may be reduced in size by proper screen selection and regulated intake. most hammermills have a horizontal drive shaft which suspends vertical hammers but for some ingredients, such as dried animal byproducts, a 'vertical' hammermill is more efficient.



vibrating grit screen. the slurry consistency from a paste slaker and a slurry slaker is exactly the same after dilution of grit removal. paste slakers are available in sizes ranging from 1000lb/hr to 8000lb/hr. paste slakers are mostly used in the usa. figure 2 is a graphic depiction of a paste slaker. the grit elevator is not shown in this

“ball mill crushing in closed circuit with screens,” by davis, e. w., 1925, bulletin of university of minnesota, no. 10, minnesota school of mines experiment station this is the definitive work on the relationship between ball milling circuit productivity and the circulating load ratio. don’t let the words “crushing” or “screens” throw you off, this is about ball mill grinding (or whatever term you use for size reduction) and the classifier (whether screens



the grinding action is induced by relative motion between the particles of media - the rods, balls or pebbles. this motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage induced primarily by crushing and attrition. in autogenous grinding machines fracture of the media

3.2 shaft speed. the 2nd key design and operational aspect for a hammer mill is the rotation speed. as the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will heat the hammer at high speed, but also be sent against each other or against the screen at high speed.
