1. Basic parameters and processing capacity
This model is equipped with a Φ750×500mm roller, and the roller surface is made of wear-resistant alloy. When the feed particle size is ≤40mm, the standard processing capacity can reach 15-40 tons/hour. By adjusting the roller gap (adjustable 5-10mm), it can adapt to the crushing needs of materials of different hardness. The power configuration is 2×22kW dual motor drive, ensuring that the crushing ratio reaches 3:1 to 5:1.

2. Core application areas
Building materials industry: dedicated to the primary crushing of medium-hardness materials such as limestone and shale, and the finished products are used for the preparation of cement raw materials
Ore dressing operations: coarse crushing of medium-sized ores such as tungsten and iron ore
Environmental protection and recycling: crushing and sorting of construction waste, especially suitable for the production of recycled aggregates for concrete blocks
Chemical raw materials: particle size adjustment of materials such as coke and coal gangue

3. Technical advantages
• The hydraulic system automatically adjusts the roller spacing, and the overload protection response time is less than 0.3 seconds
• Modular design reduces the replacement time of wearing parts by 40%
• Equipped with intelligent lubrication device, the continuous working temperature is stable below 65℃
• Noise is controlled below 75dB, in line with GB12348-2008 standards

4. Precautions
Viscous materials with a moisture content of more than 8% need to be pre-screened. It is recommended to use an enhanced roller surface for long-term processing of quartz-like high-hardness materials. Regularly checking the lubricating oil status of the reducer (recommended 500-hour replacement cycle) can extend the life of the equipment by more than 30%.
