PEX300x1300 Fine Jaw Crusher For Secondary Crushing Process

In the world of stone crushing, efficiency depends on choosing the right machine for the right stage. While the standard PE series jaw crusher is known for primary crushing, the PEX Fine Jaw Crusher The fine jaw crusher is a classic, durable secondary crushing machine that serves as an alternative to cone crushers and impact crushers. In this article, we will explore the specifications, features, and real-world applications of the PEX300x1300, and why it is a top choice for crushing plants globally.

1. What is a PEX Fine Jaw Crusher?

The PEX series is a specialized type of jaw crusher designed for fine crushing. The main difference lies in the design of the jaw plates: their teeth are thinner and denser compared to ordinary PE crushers. Because of this design, the PEX300x1300 handles smaller feed sizes but produces a much finer and more uniform output. This makes it the perfect equipment for the secondary crushing stage in a stone production line.

2. PEX300x1300 Technical Specifications

Precision is key to know aobut the crushing machine in mining. Here are the detailed parameters for the PEX300x1300 model:

Model: PE300X1300
Feed Opening Size: 300x1300mm
Max feeding size: 250mm
Adjusting Discharging Opening Size: 25-60 mm
Capacity: 30-105 t/h
Motor Power: 55 kw(6P)
Types: Brand New
Jaw plates material: High-quality Mn18Cr2 (Manganese Steel)
Motor: 55KW 6P 220/380/480V 50/60HZ

3. Key Features of the PEX300x1300

The PEX300x1300 is engineered for high-load industrial environments with the following advantages:
Deep Cavity Design: Increases the crushing width and the number of material squeezes, boosting efficiency while reducing friction.
Direct Drive System: The electric motor connects directly to the drive, ensuring smoother rotation and less power loss.
Cost-Efficient Alternative: In many production lines, a PEX fine jaw crusher can replace more expensive impact crushers or cone crushers for the secondary stage.
Easy Maintenance: Features a reliable lubrication system and easily replaceable parts (like the Mn18Cr2 plates), minimizing downtime.

4. Material Applications

The PEX300x1300 handles materials with compressive strengths up to 250Mpa. Common materials include:
Hard Rocks: Andesite, Basalt, River Pebbles, Quartz, and Granite.
Ores: Iron ore, Copper ore, Bauxite, and Barite.
Industrial Materials: Steel slag, Cement clinker, Concrete, and Coal.

5. PEX vs. PE Series: What is the Difference?

When users ask, "Why choose a PEX fine jaw crusher over a PE series?", the answer lies in the crushing stage and plate design:
Tooth Design: PEX models use thinner and denser teeth plates. This design increases the contact points with the material, allowing for a smaller feed size and a much finer output.
Crushing Stage: While PE series are "Primary" crushers (breaking large boulders), the PEX300x1300 is a "Secondary" crusher, taking mid-sized stones and refining them into aggregates.
Suitability: It is more suitable for fine crushing tasks where product uniformity is critical.

4. Case Study: 100tph Andesite Crushing Plant in Indonesia

To see the PEX300x1300 in action, let’s look at a recent andesite crusher plant project in Indonesia.
The Challenge: The client needed to process Andesite—a strong volcanic rock used for road and railway construction. Andesite requires durable equipment because of its strength and abrasive nature.
The Solution: We designed a high-performance configuration to produce high-quality aggregates with an excellent shape.

Equipment List:

Primary Crusher: 1 unit of PE600X900 Jaw Crusher.
Secondary Crusher: 2 units of PEX300X1300 Fine Jaw Crushers.
Tertiary Crusher: 1 unit of PYB1200 Cone Crusher.
Screening: 1 unit of 3YK2160 Vibrating Screen.
Transport: Complete system of Belt Conveyors.

The Result: By using two PEX300x1300 units in the secondary stage, the plant achieved a stable 100tph output. The customer reported a long service life for the jaw plates and a very satisfied market for the final aggregate shape.

The PEX300x1300 Fine Jaw Crusher is a reliable, high-efficiency workhorse for any secondary crushing stage. Whether you are processing limestone for cement or andesite for highways, this machine provides the perfect balance of power and precision. Are you planning to build or upgrade your crushing plant?

People Also Frequently Asked For - FAQ:

How do you size a jaw crusher?

A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates.

How big of a rock can a jaw crusher crush?

Jaw crushers are designed to process medium to hard quarry rock or other materials, and can handle feed sizes up to several feet in size. However, the size of the rock that a specific jaw crusher can handle depends on the crusher's design and operational parameters.

What is the difference of PE jaw crusher and PEX jaw crusher?

PE jaw crusher is mainly used in the initial crushing position of the sand and gravel production plant, especially for crushing large rocks. PEX fine jaw crusher is mostly used for the secondary crushing of stone crusher plant. They are different in feeding size, output size and crushing stage.
