Mobile Jaw Crusher

Mobile jaw crushers integrate jaw crushing units with mobile chassis (tire-mounted or track-mounted), enabling on-site crushing with high mobility and no need for fixed foundations. Their structure comprises a crushing system (jaw crusher, feeder, optional screen), a mobile chassis (hydraulic-driven for terrain adaptability), and auxiliary systems (power, control, dust reduction). Manufacturing involves high-strength steel welding for frames, precision machining of 42CrMo eccentric shafts, and modular assembly, with strict quality control—raw material certification, dimensional tolerance checks (≤±1mm), and 8-hour load testing (≥95% particle size compliance). Widely used in mining (on-site ore crushing), construction waste recycling (recycled aggregate production), infrastructure, and water conservancy projects, they serve as mobile primary crushers or form integrated mobile plants, reducing transportation costs and adapting to diverse terrains

Double toggle Jaw Crusher

The double pendulum jaw crusher, characterized by its compact structure and the elliptical trajectory of the moving jaw (combining extrusion and grinding), offers 15–30% higher efficiency than the simple pendulum type, suitable for medium-hard materials (e.g., granite, iron ore) with a crushing ratio enabling output sizes of 10–300 mm. Its core components include a frame (cast or welded), fixed/moving jaws (with high-chromium or ZGMn13 liners), an eccentric shaft (40Cr/42CrMo forged), a toggle plate (safety component), and hydraulic adjustment systems. Manufacturing involves precision forging (eccentric shaft forging ratio ≥3), water toughening of liners, and strict quality control—raw material UT inspection, bearing fit clearance (0.1–0.2 mm), and 4-hour load testing (≥90% particle size compliance). Widely used as secondary or primary crushing equipment in mining (metal/non-metal ores), construction materials (recycled aggregates), and infrastructure (road base materials), it excels in small-to-medium production lines (10–200 t/h) requiring efficient medium-fine crushing.

European style Jaw Crusher

European-style jaw crushers (ESJC), adhering to EU standards, feature modular designs, intelligent systems, and advanced environmental performance, tailored for high-end crushing needs. Comprising modular frames, efficient crushing mechanisms (with ceramic-composite jaws), smart transmissions, and hydraulic protection, they offer 10–15% energy savings, ≤80 dB noise, and dust emissions ≤10 mg/m³. Manufacturing involves precision welding, 42CrMoV eccentric shafts, and digital twin debugging, with rigorous testing (100-hour full-load runs) and certifications (CE, ISO 14001). Quality control ensures -40℃ operability, 0.01 mm precision, and 100,000-hour bearing life. Widely used in premium aggregate production, metal mining, recycling, and infrastructure, ESJC delivers superior particle shape (flakiness ≤10%), predictive maintenance, and extreme condition adaptability, making it a top choice for high-standard projects globally.

Single swing Jaw Crusher

The single pendulum jaw crusher, a traditional primary crushing device, features a moving jaw swinging in a single arc around a suspension shaft, suitable for crushing materials with compressive strength ≤250 MPa (e.g., limestone, coal gangue) into 10–200 mm particles (crushing ratio 3–5). Its structure includes a frame, fixed/moving jaws, eccentric shaft transmission, shim adjustment, and toggle plate safety devices, characterized by simplicity and low cost. Manufacturing involves cast/welded frames, 40Cr eccentric shafts (forging ratio ≥2.5), and ZGMn13 jaw plates (water toughened). Quality control includes UT for castings, bearing coaxiality checks (≤0.1 mm), and load testing (≥90% particle size compliance). Widely used in small mines, construction materials, rural road building, and coal preprocessing, it offers economical reliability for low-budget, basic crushing needs, though with lower efficiency than double pendulum models.

ZPE Series Jaw Crusher

The ZPE series jaw crusher, a specialized fine crushing equipment, is designed to reduce pre-crushed materials to 5–50 mm with a crushing ratio of 8–12. Its structure, optimized from the PE series, features a deep crushing chamber (15°–18° angle), double-wave high-chromium jaw plates, and a "small eccentricity + high speed" transmission system, paired with hydraulic adjustment and overload protection for precision and efficiency. Manufacturing involves CNC welding (frame), precision machining of 42CrMo eccentric shafts (eccentricity tolerance ±0.03 mm), and composite jaw plate casting (bond strength ≥200 MPa). Quality control includes wear testing (rate ≤0.1 mm/100 hours), hydraulic cycling checks, and particle size validation (≥90% ≤10 mm product at 10 mm discharge). Widely used in aggregate production, mining secondary crushing, and industrial waste processing, it offers superior fine crushing performance with lower flakiness (≤15%) and higher continuity, making it ideal for lines requiring ≤50 mm finished products.

PE Series Jaw Crusher

The PE series jaw crusher (where "PE" stands for "Primary Crusher") is the most commonly used primary crushing equipment in industries such as mining, construction, and metallurgy. Renowned for its simple structure, large crushing ratio (typically 4–6), and wide adaptability to material hardness (capable of crushing ores and rocks with compressive strength ≤320 MPa), it serves as the "first-stage core" in material crushing production lines. Operating on the principle of "compressive crushing," it reduces large materials to a particle size suitable for subsequent processing (discharge opening adjustable from 10–300 mm) through the periodic opening and closing of the moving and fixed jaws.
