What Motor Is Used for the 57 Jaw Crusher? How Much Can It Produce Per Hour?
The 57 jaw crusher, also known as the PE500×750 jaw crusher, is a widely used coarse crushing machine in stone crushing lines. With a compact structure and reliable performance, it’s ideal for medium to small-scale production. In this article, we’ll answer two common questions:
- What size motor is required for the 57 jaw crusher?
- What is its hourly production capacity?
What Motor Is Used for the 57 Jaw Crusher?
The 57 jaw crusher is relatively small in size and has a lower capacity compared to larger models like the PE600×900. Therefore, it requires a smaller motor. The standard motor configuration is:
- Motor Power: 45 kW
For comparison, the PE600×900 (commonly known as the 69 jaw crusher) typically uses a 55 kW motor to support its higher output.
✅ Pro Tip: Choosing the right motor power helps balance production capacity and energy efficiency. Oversized motors can lead to unnecessary energy consumption.
How Much Can the 57 Jaw Crusher Produce Per Hour?
Under ideal conditions, the PE500×750 jaw crusher has a processing capacity of:
- Output Capacity: 40–130 tons per hour (t/h)
Actual performance may vary depending on:
- The hardness and size of the raw material
- Feed rate and moisture content
- Discharge port setting
- Operator skill and equipment condition

Working Principle Overview
The PE500×750 jaw crusher operates using a mechanical crushing method:
- The motor drives the belt and pulley;
- The eccentric shaft moves the movable jaw up and down;
- The stone is crushed in the cavity between the fixed and movable jaw plates;
- Crushed material is discharged from the bottom of the crushing chamber.
This process applies compressive and frictional force to break the stones, making the 57 jaw crusher ideal for hard materials like granite, basalt, limestone, and more.
Frequently Asked Questions (FAQ)
Q1: What types of stone can the 57 jaw crusher handle?
A: It can crush stones with a compressive strength of up to 320 MPa, such as granite, limestone, river pebble, iron ore, etc.
Q2: Is 45 kW the only motor option?
A: While 45 kW is standard, it may be adjusted based on specific working conditions. However, proper compatibility with the machine and power system must be ensured.
Q3: Can the discharge size be adjusted?
A: Yes. The discharge size can be adjusted between 50–100 mm to meet different particle size requirements.
Q4: How long does the equipment last?
A: With proper maintenance, the jaw crusher—made from high manganese steel—can last more than 10 years under normal operation.
