Cubicizer or Tertiary Impact Crusher? A kW per t/h Analysis From Catalogue Data
Taking the midpoint of each capacity range, the GNR K series cubicizer needs on average 0.77 kW/(t/h) and the GNR tertiary impact series 1.20 kW/(t/h). The cubicizer's installed power requirement is about 36% lower; the gap is widest at small capacities and closes around 250 t/h.
Sand Making with a VSI Crusher
A VSI crushes material by hurling it with a rotor against stone, producing cubical grains. Even the largest model accepts only 50-55 mm feed, so at least two crushing stages must come before it.
Primary, Secondary and Tertiary Crushing Stages
In a crushing and screening plant the material is reduced step by step: primary accepts up to 1300 mm, secondary 800 mm, tertiary 150 mm and VSI only 25-55 mm. This chain makes it impossible to feed a VSI directly with quarry material.
How Does an Impact Crusher Work? The Logic of the Rotor and Blow Bar
An impact crusher breaks material by striking it with blow bars on the rotor, producing cubical grains. PDK is for the primary stage, DMK for the secondary; since DMK feed is fixed at 800 mm, selection is made according to throughput.
Impact or Jaw? Crusher Type Selection Criteria
A jaw crusher breaks by compression, an impact crusher by striking. At a similar feed size the impact crusher gives 1.3 times the capacity but draws 2.2 times the power. Jaw is preferred for abrasive stone, impact for limestone.
Jaw Crusher Guide: Working Principle, Feed Opening and Model Selection
A jaw crusher is a primary machine that breaks rock by squeezing it between two jaws; the feed opening sets the largest lump it accepts, the discharge setting sets product size and capacity.
Jaw Plates for Jaw Crushers
Jaw plates are the main wear part of a jaw crusher: high-manganese (Mn13) steel with work hardening, fixed and swing jaw, tooth profile and replacement.
