1. Product Overview

PE250×750 jaw crusher is a popular medium-sized stone primary crushing machine. It is designed for coarse crushing of various hard rocks and ores in mining, quarrying, construction, road and railway industries. Featuring sturdy welded frame, durable movable jaw plate and stable eccentric shaft, this jaw crusher realizes continuous high-efficiency stone crushing. With large feeding opening, uniform output particle size and low failure rate, it is the most cost-effective primary crushing equipment for medium and small crushing production lines.

This model is widely used for crushing raw stones such as granite, basalt, limestone, iron ore, river pebbles and quartz stone. It can work independently or cooperate with cone crusher, hammer crusher and sand making machine to form a complete stone crushing production line.

2. Technical Parameters

3. Working Principle

The jaw crusher adopts extrusion crushing working principle. The motor drives the eccentric shaft to rotate through the belt pulley, which makes the movable jaw plate perform periodic reciprocating motion. When the movable jaw plate moves close to the fixed jaw plate, the materials are squeezed, rubbed and crushed. When the movable jaw plate moves away, the crushed materials smaller than the discharge gap fall down and discharge from the bottom. The raw materials are repeatedly extruded and crushed in the crushing cavity to meet the required particle size standard.

4. Product Advantages

4.1 Strong Crushing Capacity

PE250×750 jaw crusher is suitable for hard materials with compressive strength below 320MPa. The deep crushing cavity design increases feeding quantity and improves production efficiency without material blocking.

4.2 Wear-resistant & Long Service Life

The jaw plate, side lining plate and other vulnerable parts are made of high manganese steel. The thickened welded main frame is resistant to vibration and pressure, which greatly reduces wear and prolongs equipment service life.

4.3 Easy Discharge Size Adjustment

Equipped with wedge adjustment device, the discharge particle size can be adjusted quickly and stably. Simple structure ensures no jamming during the adjustment process.

4.4 Stable Operation & Low Vibration

Optimized eccentric shaft and heavy-duty flywheel design ensure smooth operation, low vibration and low noise. The equipment runs stably under long-term continuous working conditions.

4.5 Convenient Maintenance

Reasonable structural layout makes daily inspection, lubrication and vulnerable parts replacement easier. It effectively reduces maintenance time and overall operating cost.

5. Application Scope

5.1 Processing Materials

It is widely used for hard and medium-hard minerals: granite, basalt, limestone, river pebble, iron ore, copper ore, quartz stone, coal mine slag, construction waste and other bulk raw stones.

5.2 Working Scenarios

Quarry stone crushing, mining primary ore crushing, concrete aggregate processing, construction waste recycling, highway and railway infrastructure construction, building materials factory raw material processing.

6. Product Value

PE250×750 jaw crusher has high production efficiency and stable performance. It is the mainstream primary crushing equipment in medium and small crushing lines. With low failure rate and affordable price, this jaw crushing machine can effectively reduce production investment cost. It is the preferred coarse crushing equipment for global medium and small mining investors and aggregate processing plants.
