ABON Low Speed Sizers Machine by Aravindan

Low Speed Sizing is one of the more unique crushing technologies in the world today. A combination of high torque and low roll speeds with a unique tooth profile in the ABON equipment leads to a specified product with a minimum of fines creation.In essence the interaction of tooth, spacer and roll set up a “Sized Void” which in turn “Sizes” oversize material when feed through the machines rolls. Undersize material basically “free falls” through the unit with little or no further size reduction.The actual rotating tip speed of the tooth or sizing element in an ABON Sizer can be as low as 0.8 m per sec (primary applications) and no higher than 1.8 m per sec (tertiary & quaternary applications).

ABON Sizers have several unique features to exploit extending from this low roll speed principle -

• Environmental features of low noise, low dust and minimal fines creation.
• Simple Infrastructure requirements due to minimal dynamic loads placed on surrounding supports and structure. Units also have the ability to process full ROM envelopes and are not reliant on pre scalping of undersize material.

• Minimal fines creation from shear-breakage “sizing”
• Insensitive to clay and sticky materials
• Pre-scalping of undersize is not required
• Exceptionally low headroom requirements
• Simple infrastructure requirements due to minimal dynamic loads placed on the supports and structure
• Primary units that start up under a full load
• Long wear life of consumable components due to positive bite and minimal feed slip
