Catalog of 140th Coal Crusher: Complete Guide to Models, Specifications, and Selection

What Is a 140th Coal Crusher?

A 140th coal crusher refers to a coal crushing machine with a rated processing capacity of 140 tons per hour (t/h). This mid-to-high capacity class is widely used in coal mining, power plants, coal preparation plants, and cement production lines. The “140th” designation indicates the throughput rate—140 tonnes per hour—making it a popular choice for medium-scale industrial operations that need reliable, continuous coal size reduction.

When you search for a catalog of 140th coal crusher, you are typically looking for a complete listing of available models, their technical parameters, feeding sizes, output sizes, motor power, and applications. This article provides that catalog in a structured, easy-to-compare format.

Why Capacity of 140 t/h Matters

Choosing the right crusher capacity directly affects:

• Production efficiency – A 140 t/h crusher matches the output of medium-sized coal handling systems.
• Energy consumption – Properly sized equipment avoids over-crushing and wasted power.
• Operating cost – Matching capacity to demand reduces wear and downtime.
• System integration – 140 t/h units pair well with standard belt conveyors, screens, and feeders.

Catalog of 140th Coal Crusher Models

Below is a representative catalog of crusher types that can achieve approximately 140 tons per hour when processing coal (capacity varies with coal hardness, moisture, and feed size).

1. Hammer Crusher – 140 t/h

Hammer crushers are the most common choice for 140 t/h coal crushing due to their high reduction ratio and simple structure.

2. Ring Hammer Crusher – 140 t/h

Ring hammer crushers offer uniform output and are ideal for brittle coal with low moisture.

3. Double Roller Crusher – 140 t/h

Double roller crushers produce minimal fines and are excellent for controlled product sizing.

4. Jaw Crusher – 140 t/h (Primary Crushing)

Jaw crushers handle large feed sizes and are often used as the first stage before secondary crushing.

5. Impact Crusher – 140 t/h

Impact crushers deliver a good cubical product shape but require careful maintenance for abrasive coal.

6. Mobile Coal Crusher – 140 t/h

Mobile units provide flexibility for scattered coal deposits and construction sites.

Key Specifications to Compare in a 140th Coal Crusher Catalog

When reviewing any catalog of 140th coal crusher, pay attention to these parameters:

1. Capacity (t/h) – Confirm it meets 140 t/h under your coal conditions.
2. Max Feeding Size (mm) – Must match your upstream equipment.
3. Discharge Size (mm) – Determines downstream screening and milling needs.
4. Motor Power (kW) – Affects energy cost and electrical infrastructure.
5. Moisture Tolerance – Coal with high moisture may clog some crusher types.
6. Wear Parts Material – High-chrome or manganese steel extends service life.
7. Dimensions & Weight – Important for plant layout and transport.
8. Automation Level – PLC control improves safety and consistency.

How to Select the Right 140 t/h Coal Crusher

Use this selection flow:

1. Determine coal properties – Hardness (Mohs), moisture, abrasiveness, and bulk density.
2. Define feed and product size – Required reduction ratio guides crusher type.
3. Check capacity curve – Ensure 140 t/h is achievable at your specific feed size.
4. Evaluate power supply – Match motor power to available electricity.
5. Consider maintenance – Roller and hammer crushers need regular part replacement.
6. Review total cost – Include installation, spare parts, and energy over 5–10 years.

Applications of 140 t/h Coal Crushers

• Thermal power plants – Crushing coal to boiler feed size.
• Coal preparation plants – Preparing clean coal and middlings.
• Coking coal plants – Producing controlled-size coke feed.
• Cement kilns – Coal firing preparation.
• Brick and ceramic industries – Fuel processing.
• Mining sites – Primary and secondary size reduction.

Frequently Asked Questions (FAQ)
