Jaw crusher is the most mainstream primary crushing machine in mineral processing, quarry aggregate production, road construction and construction waste recycling industry. As professional jaw crusher manufacturer, we supply full series stone jaw crusher including PE coarse jaw crusher, PEX fine jaw crusher, European type jaw crusher, diesel portable jaw crusher and track mobile jaw crusher to meet different raw material and output demands.
H2 1. Working Principle of Jaw Crusher
The core crushing mechanism of rock jaw crusher relies on the reciprocating extrusion between fixed jaw plate and movable jaw plate driven by eccentric shaft. When the movable jaw plate moves close to fixed jaw plate, hard stones, ores are squeezed, split and bent to finish coarse crushing; when movable jaw retreats, qualified materials fall down from the discharge port under gravity, uncrushed stones stay in crushing cavity for secondary squeezing. Our jaw crusher adopts deep crushing cavity without dead zone, greatly improving feeding volume and hourly capacity, which makes this jaw stone crusher widely recognized by global mining customers.
H2 2. Main Types of Jaw Crusher For Different Crushing Stages
PE Series Primary Jaw CrusherPE jaw crusher belongs to coarse crushing equipment, maximum feeding size up to 1200mm, processing capacity 3-1200t/h, suitable for large lump granite, basalt, river pebble, iron ore primary crushing in complete crushing plant.
PEX Series Fine Jaw CrusherPEX jaw crusher is medium & fine crushing jaw crusher, small feeding opening, narrow discharge adjustment range, used for secondary crushing to get uniform small aggregate particles.
European Type Jaw CrusherOptimized heavy-duty frame, thickened jaw plate, wedge block quick discharge adjustment, lower failure rate, ideal large jaw crusher for high-hardness rock quarry project.
Diesel Jaw Crusher & Mobile Jaw CrusherDiesel portable jaw crusher works without electric power, perfect for remote mountain mining sites; track mobile jaw crusher integrates feeding, crushing and conveying, no foundation installation, flexible for construction waste recycling.
