Coal Crushing
Coal remains one of the most important energy and industrial raw materials worldwide. Before coal can be burned, coked or further processed into powder, it must first be reduced to a controllable particle size. This is exactly what a coal crusher does. As a professional manufacturer of mining crushing, ore grinding and mineral processing equipment, Baichy Heavy Industry supplies a full range of coal crushing equipment for power plants, coking plants, coal washing plants and coal mines.
In this guide, we explain the main coal crusher types, their working principles, selection criteria and key parameters, so you can choose the right coal crusher machine for your operation.
What Is a Coal Crusher?
A coal crusher is a machine designed to break large lumps of raw coal into smaller, uniform particles. Raw coal can be as large as 300–1000 mm when it leaves the mine face, but downstream processes usually require a much smaller feed. A reliable coal crusher performs size reduction by compression, impact or shear, depending on the crusher type.
Choosing the right coal crushing equipment directly affects product quality, energy consumption, wear cost and the efficiency of the whole preparation plant.
Why Does Coal Need Crushing?
Coal crushing equipment is not optional—it is a mandatory step in almost every coal processing line. There are several reasons:
- Uniform size for combustion: Boilers and furnaces require a consistent coal particle size for stable and efficient burning.
- Coking requirements: Coking coal must be crushed and blended to specific size ranges before entering the coke oven.
- Grinding preparation: Before coal enters a ball mill or vertical mill, it must be pre-crushed to a size the mill can accept.
- Separation efficiency: In coal washing and flotation, a uniform particle size improves separation accuracy and recovery rate.
- Logistics and handling: Crushed coal is easier to convey, store and feed into silos or feeders.
Main Types of Coal Crushers
There is no single "best" coal crusher—the right choice depends on your feed size, capacity, moisture and target output. The following are the most common types of coal crushing equipment offered by Baichy Heavy Industry.
Hammer Crusher for Coal
Coal Crusher - hammer crusher
The hammer crusher is the most widely used coal crusher machine in coal crushing plants. It uses high-speed rotating hammers to strike and shatter coal against the crushing chamber. It is ideal for medium-hard and brittle materials, handles high moisture reasonably well, and produces a uniform product. Baichy PC series hammer crusher is especially popular for coal, limestone and gypsum.
Advantages: high reduction ratio, low investment, simple structure, easy maintenance.
Double Roll Crusher
coal crusher - double roller crusher
The double roll crusher (2PG series) crushes coal between two counter-rotating rollers. It works mainly by compression and shearing, producing fewer fines and a more uniform particle shape. It is an excellent coal crusher for the coal washing and coking industries where over-crushing must be avoided.
Advantages: low fines generation, low energy consumption, adjustable discharge size, wear-resistant rollers.
Impact Crusher
Coal crusher - impact crusher
The impact crusher breaks coal by the impact of hammers or blow bars at high speed. It provides a high reduction ratio and good particle shaping. It suits medium-hard coal and can be used as a secondary stage in a complete coal crushing equipment line.
Advantages: high capacity, cubic product shape, low operation cost per ton.
Jaw Crusher for Primary Crushing
Coal crusher - Jaw Crusher
The jaw crusher is used as the primary coal crusher when raw coal is very large. It compresses coal between a fixed jaw and a movable jaw. While it is not the final sizing stage, it reduces oversized lumps to a manageable range for downstream coal crushing equipment.
Advantages: strong structure, handles very large feed, stable performance.
Ring Hammer Crusher
The ring hammer crusher (PCH series) is a variant of the hammer crusher designed specifically for coal. Its ring-shaped hammers both impact and shear the material, making it highly effective for wet and sticky coal while minimizing clogging.
Advantages: handles high-moisture coal, low power consumption, large capacity.
Coal Crusher Parameter Comparison Table
The table below compares the main coal crushing equipment models offered by Baichy Heavy Industry. Parameters can be customized to your exact requirements.
| Crusher Type | Model Series | Max Feed Size (mm) | Discharge Size (mm) | Capacity (t/h) | Motor Power (kW) | Best Application |
|---|---|---|---|---|---|---|
| Jaw Crusher | PE / PEX | ≤1200 | 25–150 | 16–1050 | 7.5–280 | Primary crushing of large raw coal |
| Hammer Crusher | PC | ≤350 | ≤25 | 5–300 | 18.5–800 | Medium-hard coal, main coal crusher |
| Ring Hammer Crusher | PCH | ≤300 | ≤30 | 8–200 | 11–800 | Wet / sticky coal crushing |
| Double Roll Crusher | 2PG | ≤100 | 2–30 | 5–300 | 5.5–280 | Low-fines coal for washing & coking |
| Impact Crusher | PF | ≤350 | ≤50 | 30–550 | 30–630 | Secondary coal crushing |
*Note: exact parameters are configured according to raw material and production requirements.*
How to Choose the Right Coal Crusher？
Selecting the proper coal crushing equipment should be based on four key factors.
Feed Size and Moisture
If your raw coal is large (above 300 mm), start with a primary jaw crusher. If the coal is wet or sticky, choose a ring hammer crusher or double roll crusher to avoid clogging. High-moisture coal reduces the efficiency of impact crushers.
Required Capacity
Calculate the actual hourly throughput you need. Over-sizing a coal crusher wastes capital and energy; under-sizing creates bottlenecks in the whole crushing line. Baichy can design a coal crushing equipment line matched to your tonnage.
Target Output Size
Different downstream processes need different sizes. Combustion typically needs 0–25 mm, while coking and washing often need a more precise and uniform range. Choose a coal crusher machine whose discharge adjustment matches your product spec.
Operating Cost and Wear
Wear parts are the biggest running cost. Hammer crushers are economical to buy but have higher hammer wear; double roll crushers have a higher initial cost but lower maintenance. Balance your budget with the lifetime cost of the coal crushing equipment.
