KCY Slag Crusher Overview

KCY Slag Crusher is designed for crushing slag in power plant conveying systems. The single-roller structure breaks oversized slag into smaller particles, preparing the material for more stable conveying, cooling, storage or further handling.


Unlike an independent general-purpose crusher, the equipment is selected as part of a complete slag handling process. Its configuration should match the upstream discharge equipment, downstream conveyor, slag temperature, moisture level and required processing capacity.

Main Slag Crusher Components

Housing and Liner

Housing and Liner

The housing contains the crushing process and connects with adjacent equipment. Internal liner plates protect the main body from direct contact with abrasive slag during operation.

Roller and Gearbox

Roller and Gearbox

The gearbox transfers driving power to the main roller shaft. The rotating roller then moves and compresses slag against the fixed crushing components inside the housing.

Jaw and Tooth Plates

Jaw and Tooth Plates

Jaw plates and toothed plates directly contact oversized slag and apply the crushing force required to reduce large particles before they enter the downstream conveying process.

Bearings and Pedestals

Bearings support stable shaft rotation, while the split bearing pedestal structure simplifies installation and maintenance and helps control the alignment of the main roller shaft.

Slag Crusher Application Areas

Thermal Power Plants

Thermal Power Plants

KCY Slag Crusher is used in thermal power plant slag conveying systems to reduce oversized bottom slag generated during boiler operation. By controlling the particle size before conveying, the crusher helps prepare the slag for subsequent transportation, cooling or storage. Equipment selection should be based on the boiler slag discharge method, actual slag output, temperature and downstream system arrangement.

Dry Slag Conveyor Systems

In a dry slag conveyor system, high-temperature slag may contain oversized and irregular particles that must be reduced before entering the next conveying stage. The single-roller slag crusher works together with the dry slag conveyor to provide a controlled material size. Connection design should consider inlet temperature, conveyor capacity, installation height, thermal expansion and equipment interface dimensions.

Dry Slag Conveyor Systems
Wet Slag Handling Systems

Wet Slag Handling Systems

The crusher can also be applied under wet slag working conditions where moisture affects material flow, adhesion and discharge behavior. The equipment layout should provide stable feeding and sufficient maintenance access while reducing material accumulation around the inlet and outlet. Crusher capacity and discharge size should be confirmed according to actual wet slag characteristics and downstream conveying requirements.

Slag Crusher Performance Advantages

KCY Slag Crusher is developed around the operating requirements of power plant slag handling, including temperature, wear, sealing, maintenance access and integration with conveying equipment.

Wet and Dry Conditions

The single-roller crusher can operate in wet slag systems and high-temperature dry slag systems, allowing it to match different power plant slag discharge and conveying arrangements.

Adjustable Crushing Size

The product design supports adjustment of slag crushing granularity, allowing the equipment configuration to be matched with downstream particle-size and conveying requirements.

Maintenance Rail Structure

The crusher can be installed on roller wheels and horizontal guide rails. During maintenance, the machine can be moved outward to improve access to internal components.

High-Temperature Tooth Plate

The precision-cast high-chromium alloy tooth plate is specified for temperatures above 450°C and provides wear resistance for direct contact with hot and abrasive slag.

Slag Crusher FAQs

1. What slag can the crusher process?
The KCY single-roller slag crusher is designed for power plant slag conveying systems. It can operate under wet slag and high-temperature dry slag conditions. Final selection depends on the slag temperature, moisture, hardness, particle size and required capacity.
2. What is the maximum feed size?
The listed maximum feed particle size for the KCY slag crusher series is 150 mm. Actual feeding conditions should still be reviewed, especially when the slag contains irregular oversized pieces or materials that may affect stable crusher operation.
3. What discharge size can be achieved?
The listed discharge particle size is no more than 30 mm. The crushing granularity can be adjusted according to the equipment configuration and downstream conveying requirements. Project data should be confirmed before determining the final setting.
4. What capacity options are available?
KCY lists single-roller slag crusher options with handling capacities of up to 30 t/h, 40 t/h and 60 t/h. The suitable capacity should be selected according to normal output, peak slag volume and operating schedule.
5. What information is needed for selection?
Please provide the slag type, temperature, moisture level, maximum feed size, required discharge size, hourly capacity, operating time, installation space and equipment interface drawings. These details help us prepare a more suitable crusher proposal.
