I. Project Overview
This case study features a power plant boiler slag solid waste recycling project in Sichuan Province. The customer’s raw slag feed size was 20mm, with production requirements to crush the material to under 5mm finished aggregates for subsequent building material recycling and solid waste monetization.
After comparing multiple equipment brands and verifying on-site performance, the customer ultimately selected a Huashengming roll crusher for the fine crushing operation, ensuring stable output particle size and continuous production.
II. Site Conditions and Customer Requirements
Power plant boiler slag is hard and highly abrasive. Combined with Sichuan’s humid climate, stockpiled slag retains moisture. Traditional crushing equipment often produces excessive fines, uneven particle sizes, sticking and clogging, and rapid wear — making it difficult to consistently achieve the required under-5mm output.
The customer’s production requirements were clear and strict:
Feed size: ≤20mm
Finished product: strictly under 5mm
Stable operation with low failure rate and controllable maintenance costs
Adaptability to Sichuan’s humid conditions, eliminating material sticking and clogging shutdowns

III. Customized Solution
Addressing the high hardness, high abrasiveness, and moisture sensitivity of boiler slag, Huashengming precisely matched the customer with a roll crusher. The equipment uses a low-speed compression crushing principle, specifically designed for fine crushing of high-wear solid waste materials with excellent adaptability to the working conditions.
The equipment features precise roll gap adjustment to lock output size under 5mm as needed. The core roll shells are made of thickened wear-resistant alloy material, specifically engineered to withstand the high abrasion of slag. The machine structure is optimized for humid environments, providing anti-sticking and anti-clogging performance with smooth material flow — fully adapted to Sichuan’s humid production conditions, ensuring long hours of continuous operation.
IV. Operational Results and Project Advantages
After installation and commissioning, the equipment has demonstrated stable performance with all production targets met, fully resolving the customer’s fine crushing challenges:
1. Precise particle size control with zero oversized output
20mm boiler slag is consistently crushed to under 5mm, producing uniform, well-shaped particles with minimal fines. No recirculation or reprocessing is required, significantly reducing screening equipment load and greatly improving finished aggregate qualification rates.
2. Strong adaptability for stable 24/7 production
The equipment perfectly adapts to Sichuan’s humid climate. When processing moist slag material, it resists sticking, chamber clogging, and jamming. With extremely low failure rate, it supports long continuous operation without frequent shutdowns for cleaning or maintenance — maintaining a stable production rhythm.

3. Durable and wear-resistant with lower maintenance costs
The specially designed wear-resistant roll shells deliver long service life far exceeding conventional crusher wear parts, significantly reducing replacement frequency. Combined with low-speed operation, overall equipment wear and energy consumption are minimized, substantially reducing long-term operating and maintenance costs.
4. High material utilization with significant economic benefits
The compression crushing principle fundamentally prevents over-crushing, maximizing retention of usable aggregates and improving slag solid waste utilization. The equipment transforms waste slag into high-value recycled building material aggregates, generating stable revenue for the customer.
V. Project Summary
This Sichuan power plant boiler slag crushing project fully demonstrates the outstanding performance of Huashengming roll crushers in solid waste fine crushing applications. For high-hardness, moist slag conditions, the equipment delivers precise particle size control, stable operation, low consumption, and high output — providing a mature and reliable fine crushing solution for various power plant boiler slag solid waste recycling projects.
