PE 250x400 Jaw Crusher.jpg

In mining, building materials, infrastructure, and other industries, primary crushing (coarse crushing) of materials is the cornerstone of the entire production process. For projects with small to medium-sized production capacity or laboratory research, choosing a small jaw crusher with stable performance and reasonable price is crucial. The PE 250x400, a classic model in its class, has become the preferred choice for many users due to its exceptional reliability and high cost-effectiveness. This article will provide a comprehensive introduction to this "small crushing pioneer."

I. Introduction to the PE 250x400 Jaw Crusher

The PE 250x400 is a jaw crusherdesigned according to advanced international technical standards. The "PE" in its model number stands for "jaw crusher," the "250" designates a 250 mm feed opening width, and the "400" designates a 400 mm feed opening length. This machine is renowned for its simple structure, easy operation and maintenance, and high crushing ratio. It is ideal for processing various ores and rocks with a compressive strength of up to 320 MPa, such as granite, marble, basalt, and limestone.

II. Core Advantages

• Sturdy and Durable Structure: The movable and fixed jaw plates are made of high-quality manganese steel, offering strong wear resistance and a long service life. The integral steel frame structure ensures stable operation and can withstand high-intensity impact loads.

• High Crushing Efficiency: The optimized cavity design eliminates dead zones, improving feed capacity and output, ensuring efficient crushing efficiency.

• Adjustable Discharge Size: By adjusting the gasket or ejector pin at the bottom of the jaw plate, the discharge size can be flexibly controlled to meet the product size requirements of different processes.

• Low Operating Cost: The simple structure, minimal maintenance points, and easy replacement of wearing parts significantly reduce ongoing maintenance costs and time.

• Flexible and Widely Applicable: It can be used not only in small and medium-sized sand and gravel aggregate production lines, but also in crushing materials in the metallurgical, mining, chemical, building materials, highway, railway, and water conservancy industries.

IV. Operating Principle

The PE 250x400 jaw crusher operates in a "squeezing and extruding" mode. The motor drives the eccentric shaft via a pulley, causing the movable jaw to perform periodic reciprocating motion. When the movable jaw approaches the fixed jaw, the material is crushed by squeezing, splitting, and bending between the two jaw plates. When the movable jaw moves away from the fixed jaw, the crushed material is discharged from the discharge port at the bottom of the crushing chamber under the action of gravity.

V. Main Applications

1. Small and medium-sized quarries and sand plants: Used as primary crushing equipment to crush raw ore or large stones.

2. Construction waste disposal: Used for preliminary crushing and recycling of construction waste such as concrete blocks and bricks.

3. Mining: Used for primary crushing of metal ores such as gold, iron, and copper.

4. Laboratories and research institutes: Used for small-batch crushing and analysis of ore and rock samples.

VI. How to Choose a Reliable PE 250x400 Jaw Crusher Manufacturer?

When choosing equipment, in addition to price, you should also consider the manufacturer's strength and after-sales service:

• Investigate the manufacturer's qualifications: Choose a reputable manufacturer with many years of production experience and mature technology.

• Check the equipment materials: Pay attention to the material and brand of core components (such as jaw plates, eccentric shafts, and bearings).

• Request a trial run video: Request a video of the equipment in action to observe its stability and discharge performance.

• Comprehensive after-sales service: Ensure the manufacturer provides installation guidance, technical training, and timely spare parts supply.

The PE 250x400 jaw crusher, with its classic design, reliable performance, and wide applicability, has established a solid position in the small crushing equipment market. If you are looking for an economical, practical, and durable primary crushing machine for your project, the PE 250x400 is undoubtedly a worthy option.
