During coal combustion, power generation, and industrial boiler operations, a massive amount of solid waste such as coal slag and furnace cinder is generated. Efficiently crushing these materials and converting them into unfired bricks, cement admixtures, or construction aggregates is a crucial step in achieving resource recycling and environmental compliance. However, coal slag often has high moisture content, strong stickiness, and contains various impurities. Traditional crushers with screen bottoms easily suffer from “screen blinding,” leading to frequent shutdowns for cleaning, which severely restricts production efficiency.
To address this industry pain point, Huashengming Heavy Industry has launched a customized crushing solution specifically designed for coal slag and other solid waste treatment. We provide two core pieces of equipment: the Double-Stage Screenless Crusher and the Hydraulic Double Roll Crusher, aiming to completely solve the crushing challenges of high-moisture materials and help enterprises reduce costs and increase efficiency.
Coal Slag
Core Advantages of the Huashengming Coal Slag Crushing Solution:
-
Screenless Design to Completely Eliminate Clogging
Whether it is the double-stage crusher or the roll crusher, Huashengming adopts a revolutionary “screenless” discharge structure. After crushing, the material is smoothly discharged relying on its own gravity and the thrust of the hammers/roll skins. This fundamentally eliminates the industry’s stubborn problem of screen blinding caused by high-moisture and sticky coal slag, ensuring 24/7 continuous and stable operation of the production line. -
Versatile for Both Dry and Wet Materials with Strong Adaptability
Given the complex composition of coal slag, Huashengming equipment demonstrates excellent tolerance. Whether it is freshly discharged dry coal slag, high-moisture coal slag that has been washed or left outdoors, or materials containing a small amount of mud or metallic foreign objects, the equipment handles them effortlessly. The hydraulic roll crusher also features a built-in overload protection system; when encountering uncrushable foreign objects, the roll body automatically releases, significantly reducing the risk of component damage. -
Precise Particle Size Control with Excellent Product Gradation
The discharge size is no longer limited by a fixed screen but is flexibly adjusted through the hydraulic system by changing the gap between the hammers and liners or the roll gap. The equipment can stably produce fine materials below 3mm with uniform particles and a low over-crushing rate, perfectly meeting the strict particle size requirements for unfired brick pressing, cement batching, and underground backfilling. -
Flexible Extrusion for Low Dust and Eco-Friendliness
Compared to traditional impact crushing, the Huashengming Hydraulic Double Roll Crusher uses a low-speed extrusion crushing principle, generating extremely low dust during operation. Combined with a sealed conveying structure, it significantly improves the environmental conditions of the workplace, highly aligning with the environmental control requirements of green mining and solid waste treatment projects. -
Hydraulic Opening for Time-Saving and Labor-Saving Maintenance
The equipment comes standard with a hydraulic opening device. When inspecting or replacing high-wear-resistant alloy hammers/roll skins, a single operator can easily open and close the machine casing. This not only greatly reduces the labor intensity of workers but also shortens downtime for maintenance, ensuring high comprehensive equipment utilization.

Application Scenarios and Value Conversion
Through the Huashengming coal slag crushing solution, the “black waste” originally piled up in the open can be locally converted into high-value “green resources.” The crushed fine coal slag can be directly used to produce eco-friendly unfired bricks and aerated concrete blocks, or supplied to cement plants as a high-quality admixture. In mining areas, it can also be paired with a mobile crushing station to crush coal slag on-site into underground backfill aggregates, achieving a closed loop of goaf treatment and solid waste consumption.
