Lab Jaw Crusher
Compressive Primary Crushing for Hard & Coarse Laboratory Samples
Overview
The Oswal Lab Jaw Crusher delivers controlled compressive size reduction for hard, coarse, and abrasive materials. A fixed jaw and a moving jaw driven by an eccentric shaft apply high crushing force, producing uniform output particles. The discharge gap is fully adjustable to set the required product size ahead of splitting and fine grinding.
Process Role
In a cement laboratory, representative samples collected from belts, silos, and kilns arrive as lumps or coarse fractions. The jaw crusher delivers the first reduction stage, converting raw material, limestone, clinker, or additive lumps into crushed fractions suitable for further division and XRF preparation without introducing analytical bias.
Engineering Principle
Compressive force applied between a fixed and an oscillating jaw fractures hard material through its natural cleavage planes. The adjustable discharge gap and toggle plate mechanism ensure consistent output size and protect the crusher from uncrushable objects.
Core Engineering Features
Fixed & Moving Jaw Mechanism
Eccentric-driven moving jaw delivers high compressive force for hard limestone, raw materials, and clinker.
Adjustable Discharge Gap
Precise output particle size is set by a simple gap adjustment, eliminating over- or under-crushing.
Abrasion-Resistant Jaw Plates
Manganese steel jaw plates withstand abrasive cement process materials with extended plate life.
Overload Protection
Toggle plate mechanism protects the crusher and drive from damage if uncrushable objects enter the feed.
