Choosing the right mobile roller sand making machine requires comprehensive raw material characteristics, capacity requirements, mobile configuration and long-term operation and maintenance costs, the following is a scientific selection guide:

mobile roller sand making machine

1. Adaptation of raw material characteristics

Hardness and composition

Medium and low hardness materials (limestone, gangue): directly choose the standard roller surface models (such as 2PGY800 × 800), roller skin material for high manganese steel can meet the demand.
High hardness materials (granite, basalt): need to choose composite alloy roller skin or increase the jaw pre-crushing, to avoid excessive wear of the roll surface (such as 2PGY1800×1000 with pre-crushing module).
Wet and sticky materials (mud content>15% or water content>25%): scraper cleaning device must be selected to prevent sticky rollers from clogging (WMS model supports customised scraper).

2. Mobile configuration options

Crawler chassis: adapting to rugged terrain, preferred for projects with hourly output ≥100 tonnes (e.g. 2PGY1500×1000), with a 50% increase in transfer efficiency.
Wheeled chassis: suitable for frequent movement on flat sites, low cost (standard for small models).
Integrated design: screening + conveying module integration, reduce auxiliary equipment investment (medium-sized models and above support customisation).

3. Special scenario solutions

High wet material processing (such as silty soil)

Add hydraulic scraper + anti-stick coating on roller surface, humidity tolerance is increased to 35%.

Fine particle size control (sand for concrete)

With closed-circuit screening system (e.g. 2PGY1200×800 + vibrating screen), the proportion of 0-5mm fine sand reaches 90%.

No power supply scenario

Diesel-powered models (e.g. 2PGT610×400) support continuous operation in remote mining areas.

4. Procurement and O&M Recommendations

Cost Optimisation

Small projects: choose spring-regulated models (e.g. 2PGT750×500), investment of 30,000-100,000 RMB, easy maintenance.
For large projects: hydraulic CNC model with lower long-term cost (20% reduction in energy consumption and 3 years of roll skin life).

Service guarantee

Preferred vendors that support test run with material and installation in the factory (e.g., Huasheng Ming provides 24-hour fault response).

Long-term maintenance

Monthly inspection of roller surface wear and lubrication system, and replacement of roller sleeves every six months when working with high hardness materials.

Flexible operation: 2PGT400×250 wheeled chassis, low-cost and quick turnaround.
Balanced performance choose medium-sized: 2PGY800×800 hydraulic adjustment, suitable for 50t/h mainstream demand.
Choose flagship for large projects: 2PGY1800×1000 crawler, lifetime roller body + intelligent control.
