Advantages and Disadvantages of PE Jaw Crusher

Advantages of PE Jaw Crusher
Stable structure and strong durability
Adopt high-strength cast steel body and wedge adjustment device to ensure long-term stable operation. The movable jaw and fixed jaw are made of high-quality manganese steel, which is resistant to pressure and wear, and the service life is extended by more than 30%, which is suitable for high-load working environment.
High efficiency and energy saving, low cost
The unique crushing chamber design makes the material bite tightly, the crushing efficiency is increased by 15%-20%, and the energy consumption is significantly reduced. The optimized lubrication system reduces downtime and maintenance time, further reducing operating costs. For example, the PE-600×900 model has a production capacity of 80-160t/h, which is suitable for medium-sized production lines.

Strong adaptability and wide application
The feed particle size can reach 1200mm, and the discharge particle size is adjustable (10-350mm) to meet the needs of coarse crushing and medium crushing. Compatible with a variety of materials such as hard rock, sand and gravel, metal ore, etc., it is widely used in mines, sand and gravel plants, concrete mixing plants and other industries.
Intelligent operation, safe and reliable
Equipped with overload protection device and real-time monitoring system of operation status, the failure rate is low. One-button start-stop design simplifies the operation process, reduces labor costs, and improves production safety.

Disadvantages of PE jaw crusher
The adjustment method is cumbersome
The adjustment of the gasket requires manual operation when stopping the machine, which affects the continuity of production. In contrast, the PEW series adopts a hydraulic wedge adjustment device, which is safer and more convenient to adjust.
The life of the bearing seat is short
The bearing seat and the frame adopt a welded structure, which is prone to breakage due to stress concentration after long-term use. Industry leaders eliminate casting stress by placing them in the open air for more than 1 month, but small manufacturers often ignore this process, increasing equipment risks.
Low efficiency of manual lubrication
Traditional PE jaw crushers require manual lubrication, which is difficult to operate and easy to miss maintenance points, affecting production efficiency. The integrated jaw crusher adopts a centralized grease lubrication system, which saves more time for maintenance.

Uneven product size
The intermittent extrusion crushing method leads to poor particle uniformity, and screening equipment is required to optimize the quality of the finished product. In addition, metal collision produces high-frequency vibration and high noise, which has certain requirements for the working environment.
Initial investment and maintenance costs
Although the PE series is cheaper, the welded bearing housing has a short life span and parts need to be replaced regularly. The long-term maintenance cost may be higher than that of modular design models (such as integrated jaw crushers).
