Engineered for primary reduction stages in mining and aggregate circuits, PE Series Jaw Crushers process various ores and rocks exhibiting compressive strengths up to 320MPa. Incorporating deep crushing cavities and heavy-duty structural assemblies, this classic equipment delivers medium-sized output continuously. It operates in tandem with cone crushers, impactors, and sand-making machines to form complete, high-efficiency material processing lines.
Built to handle rigorous primary crushing duties across mining, construction, and chemical sectors.
Processes primary extractions of iron, copper, and gold ores, providing reliable size reduction for downstream secondary processing stages.
Crushes high-hardness river pebbles, granite, and basalt into suitable feed sizes for tertiary sand-making equipment and concrete batching plants.
Reduces limestone and quartz materials required for dry powder mortar, power plant desulfurization, and other specialized chemical processes.
Withstands severe working conditions common in coal extraction and large-scale open-pit quarrying, ensuring stable continuous output.
Utilizes split-welded cast steel frames for structural simplicity and immense impact tolerance. Heavy-duty eccentric shafts, oversized bearings, and heavy protective plates mounted above moving jaw assemblies absorb extreme feed impacts safely.
Core wear parts, including jaw plates and side guards, consist of top-tier high-manganese steel. Eccentric shafts utilize high-strength forged steel subjected to rigorous precision machining, heat treatment, and flaw detection to ensure absolute mechanical rigidity.
Mechanical fail-safes prevent catastrophic damage. If uncrushable materials exceed maximum load ratings, gray cast iron toggle plates fracture automatically. This breaks transmission forces immediately, halting operation and protecting critical frame components.
Jaw plates feature symmetrical profiles. Once lower sections wear down from abrasive friction, operators can flip plates top-to-bottom, effectively doubling service life and cutting replacement costs significantly.
Discharge settings adjust via straightforward shim devices, allowing fast and reliable CSS tuning. Integrated centralized lubrication systems ensure moving parts receive continuous grease, reducing manual maintenance labor.
Built upon fundamental kinematics utilized since late 19th-century mining. PE models integrate modern manufacturing, strict quality control, and advanced testing equipment to deliver highly reliable primary crushing performance.
Electric motors supply primary motive power. V-belts transmit rotational force to heavy grooved pulleys, subsequently driving heavy-duty eccentric shafts into motion.
As eccentric shafts rotate, moving jaws travel upward. Angles between toggle plates and moving jaws increase, forcing moving jaw plates closer to stationary jaw plates.
Trapped rock undergoes severe compressive, rubbing, and grinding forces. Material shatters instantly under massive mechanical pressure within deep V-shaped cavities.
During downward strokes, toggle plate angles decrease. Return rods and tension springs pull moving jaws away from fixed plates. Properly sized fragmented material discharges freely via gravity through bottom openings.
