Lump Breakers
These robust machines are available as either Low or High Speed devices in the form of hopper or shaft feed or as cylinder versions. Low Speed versions are for gentle crushing duties on feeble products that require breaking down without the generation of excessive dust and fines. Heat or work sensitive granules, such as resins, are broken and reduced to smaller pieces by a dominant low-speed crushing, without the aggressive crushing and breakdown that accompanies the more vibrant action of high impact speeds. A higher proportion of granules are created in the upper size range determined by the grill, and less fines
The shafts and blades impose a three-stage action on the lumps, wedging and crushing against the casing and grill by means of the square shaft and the short radius edges of the mechanism. The residual lumps are forced through the grill by means of the sliding and crushing action of the blade edges.
High Speed breakers are more destructive of the granular materials, combining the effect of impact, wedging and trapping at a rapid rate, to fracture the chunks into a wide range of particulate fractions, none larger than will pass through the grid.
