PE500x750 Jaw Crusher
In many fields, including mineral processing, building aggregate production, building material recycling, and even laboratory research, crushing is the most fundamental and crucial first step. As a mineral processing equipment manufacturer with 20 years of professional experience, we understand that choosing a suitable, efficient, and reliable crusher is the cornerstone determining the efficiency, finished product quality, and operating costs of the entire production line.
Small crushers, with their flexibility, economy, and wide applicability, have become the ideal choice for many small and medium-sized projects, mobile crushing plants, or specific material processing scenarios. Today, we will delve into small crushers and focus on analyzing a classic model—the 500x750 jaw crusher.
What is a Small Crusher?
A small crusher does not refer to a crusher based on a specific principle, but rather is a general term for all crushing equipment with relatively small processing capacity, compact size, and suitable for small to medium-scale production. They typically possess the following core characteristics:
• Compact structure and small footprint: Easy to install and arrange in limited spaces, also suitable for mobile crushing plants.
• Low investment cost and short payback period: Relatively low initial purchase costs and subsequent maintenance and operating costs lower the entry barrier for small and medium-sized investors. • Wide and flexible applications: Not only can it be used for primary crushing in mines, but it is also widely used in construction waste recycling, road construction, brick factories, and ceramic raw material preparation.
• Easy to operate and maintain: The design typically emphasizes user-friendliness, making daily inspections and replacement of wearing parts relatively simple.
Common types of small crushers include jaw crushers, impact crushers, hammer crushers, double roll crushers, and miniaturized versions of cone crushers. Among them, the small jaw crusher is the most common choice for primary crushing due to its simple structure, reliable operation, and wide range of materials it can handle (it can handle various ores and rocks with a compressive strength not exceeding 320MPa).

Classic Model In-Depth Analysis: 500x750 Jaw Crusher
Among the many small jaw crusher models, the PE-500×750 jaw crusher is a "gold standard" product with long-term market validation and extremely balanced performance. Its model name is directly derived from its feed opening size: 500 mm wide and 750 mm long.
Core Structure and Working Principle
The 500x750 jaw crusher adopts a classic double-pendulum structure with a suspended moving jaw. Its working principle involves a motor driving a belt and pulley, which in turn drives the eccentric shaft to perform periodic reciprocating motion of the moving jaw. When the moving jaw approaches the fixed jaw, the material is squeezed, split, and crushed between the two jaw plates; when the moving jaw moves away, the crushed material is discharged from the bottom of the crushing chamber under gravity.
Performance Characteristics and Advantages
1. Robust and Reliable, High Durability: The machine body is welded from high-quality steel plates, and key components (such as the eccentric shaft) use high-strength forgings to ensure stable operation under harsh conditions. This reflects our 20 years of manufacturing experience and our pursuit of ultimate equipment reliability.
2. Deep Cavity Crushing, Excellent Capacity: The feed inlet size of the 500x750 crusher determines its maximum allowable feed particle size of approximately 425mm. Its optimized crushing chamber shape eliminates dead zones, enabling a higher crushing ratio and stable processing capacity.
3. Flexible discharge adjustment: The discharge port size can be adjusted via an adjustment device (such as a wedge or shim) to control the finished product particle size. The adjustment range is typically between 50-100mm, and can be flexibly adjusted according to subsequent process requirements.
4. Simple maintenance and low operating costs: The simple structural design and easy replacement of major wear parts (jaw plates, side guard plates, etc.) effectively reduce downtime for maintenance.
