1. PE250×750 Jaw Crusher Basic parameters of the equipment
Model definition: PE stands for jaw crusher, 250×750 represents the feed port size (width 250mm×length 750mm)
Processing capacity: 5-20 tons/hour (depending on the hardness of the material)
Motor power: 30kW
Maximum feed particle size: 210mm
Discharge port adjustment range: 25-60mm
Machine weight: about 5.5 tons

2. Core structural features
Crushing chamber design: adopts "V" symmetrical structure, the tooth plate is made of high manganese steel (ZGMn13), and the elbow plate adopts cast steel safety device
Power system: pulley transmission structure, flywheel energy storage design balances the load, and the eccentric shaft adopts alloy steel forgings
Adjustment mechanism: wedge-type discharge port adjustment device, hydraulic jack auxiliary maintenance

3. Typical application scenarios
Primary crushing field: coarse crushing of raw stones in mines (granite/limestone, etc.), recycling and treatment of construction waste, and first crushing process of cement production line
Special working conditions: small and medium-sized quarries, mobile crushing station matching, laboratory pilot crushing

4. Maintenance points
Check the wear of the jaw plate every week, replace the grease every 500 hours, check the tension of the V-belt regularly, and empty the material in the crushing chamber when the machine is shut down for a long time

V. Market positioning analysis
As the main model of small and medium-sized crushing, its advantages are: low investment cost (about 1/3 of large machines), simple structure, failure rate <3%, energy consumption ratio reaches 1.8t/kWh
