Coal gangue—a byproduct of coal mining and washing—has long been considered an environmental burden. But with the right processing solution, this abundant solid waste can be turned into high-value construction aggregates, road base materials, and brick-making raw materials.
For large-scale operations that demand both high output and environmental compliance, a 300 TPH (tons per hour) coal gangue crushing line offers the perfect balance. This article presents a complete 300 TPH crushing system built around three core machines—the jaw crusher PE 750×1060 , the double-stage crusher 2PC1620, and the circular vibrating screen 2YK3675—all equipped with advanced dust collection devices to ensure clean, sustainable production.
Why Choose a 300 TPH Coal Gangue Crushing Line?
A 300 TPH production capacity positions this line as a mid-to-large-scale industrial solution, suitable for:
● Commercial aggregate production – supplying local construction and infrastructure projects
● Brick and tile manufacturing – providing finely crushed gangue as a primary raw material
● Cement and concrete additive production – utilizing gangue as a supplementary cementitious material
● Mine backfill operations – producing graded material for underground filling
At 300 TPH, the line can process approximately 2,000–2,400 tons per day (based on an 8-hour shift), making it a highly profitable investment for mining companies, recycling centers, and building material producers.
The Three-Stage Crushing & Screening Process
Stage 1: Primary Crushing – Jaw Crusher PE 750×1060
The raw coal gangue, with feed sizes up to 630 mm, is first loaded into the PE 750×1060 jaw crusher. This heavy-duty primary crusher is engineered for high reduction ratios and continuous operation.
Key Specifications:
● Feed opening: 750 × 1060 mm
● Maximum feed size: 630 mm
● Discharge range: 80–180 mm (adjustable)
● Capacity: 110–380 TPH per unit
Note: At 300 TPH total line capacity, the jaw crusher operates efficiently within its optimal range (typically 130–180 TPH), ensuring a smooth, uninterrupted material flow to the secondary crusher.
The PE series jaw crusher features a deep crushing chamber, high-quality wear-resistant jaw plates, and a reliable lubrication system, minimizing downtime and maintenance costs.
Stage 2: Secondary & Fine Crushing – Double-Stage Crusher 2PC1620
After primary reduction, the material (now under 150–180 mm) is conveyed to the 1620 double-stage crusher—the heart of this 300 TPH line.
The double-stage crusher (also known as a two-rotor hammer crusher) combines two crushing chambers in a single compact unit. It performs both secondary and tertiary crushing in one pass, significantly simplifying the process flow.
Why the 1620 Double-Stage Crusher is Ideal for Coal Gangue:
● High reduction ratio – converts 150 mm feed to <10 mm fines in a single step
● Low energy consumption compared to two separate crushers
● Excellent for brittle materials like coal gangue, shale, and clay
● Adjustable outlet to control final particle size
For a 300 TPH output, the 1620 model is perfectly matched—it delivers rated capacities in the 250–350 TPH range, ensuring the line meets its target without bottlenecking.
Stage 3: Screening & Grading – Circular Vibrating Screen 2YK3675
The finely crushed material exits the 1620 double-stage crusher and is fed onto the 3675 circular vibrating screen (3.6 m × 7.5 m screening area). This large-capacity screen separates the material into multiple size fractions:
● >20 mm – oversize returned to the crusher (closed-loop recycling)
● 5–20 mm – coarse aggregate for road base and concrete
● <5 mm – fine powder for brick making or cement blending
The Circular Vibrating Screen offers:
● High screening efficiency – large deck area ensures thorough separation
● Circular motion – effective for moist or sticky materials like gangue
● Heavy-duty construction – long service life under continuous operation
The closed-loop design ensures that 100% of the feed is converted into sellable products, minimizing waste.
Clean & Green: Integrated Dust Collection Systems
One of the standout features of this 300 TPH coal gangue crushing line is the installation of dust collection devices on every piece of equipment. Dust is a major concern in mineral processing—it affects worker health, environmental compliance, and equipment longevity.
How the Dust Control System Works:
| Equipment |
Dust Collection Method |
| PE 750×1060 Jaw Crusher |
Enclosed feed chute + negative-pressure bag filter at discharge |
| 1620 Double-Stage Crusher |
Sealed crushing chamber + high-efficiency pulse-jet dust collector |
| 3675 Circular Vibrating Screen |
Fully enclosed screen box + dust extraction hoods |
| Conveyor Transfer Points |
Spray misting systems + enclosed belt covers |
Environmental & Operational Benefits:
● Compliance with EPA and local emission standards – particulate emissions reduced to <20 mg/Nm³
● Healthier workplace – clean air for operators and nearby communities
● Reduced maintenance – less dust ingress into bearings and motors extends equipment life
● Material recovery – collected dust can be recycled into final products (zero waste)
This integrated approach transforms what could be a "dirty" operation into a model of sustainable industrial practice.
A 300 TPH coal gangue crushing line offers an optimal solution for large-scale, profitable gangue recycling. When combined with integrated dust collection systems on all units, this line not only maximizes production efficiency but also upholds the highest environmental standards. Whether you are a mining company looking to monetize waste rock or a building materials producer seeking a reliable raw material source, this 300 TPH system delivers performance, sustainability, and return on investment.
