The portable 300×500 stone jaw crusher is a mobile crushing equipment widely used in mines, construction sites, and road construction projects.  It is favored for its compact structure, strong mobility, and convenient operation. Its core parameters are as follows:

Firstly, the equipment model "300×500" indicates a feed opening size of 300 mm (width) × 500 mm (height). The maximum feed size is typically no more than 250 mm, suitable for primary crushing of rocks, ores, concrete blocks, and other materials of medium hardness or below. Its processing capacity generally ranges from 15 to 60 tons per hour, with the specific capacity affected by material properties, humidity, and operating conditions.

The drive system usually employs a diesel engine or electric motor, with a power range of 30–55 kilowatts, ensuring efficient operation even without an external power supply. The total weight of the machine is approximately 5–8 tons, equipped with a standard trailer chassis or crawler track system for easy road transport or flexible movement on site.
