According to the demand of 100 tonnes per hour sand production, combined with the material characteristics, cost budget and equipment performance, the following is the roll crusher model recommendation and selection guide for different scenarios:

roll crusher model

1. Recommended models according to material characteristics

Medium-hard materials (limestone, gangue, etc.)

Recommended model: 2PG1200×1200 roll crusher

Production capacity: 60-100 tonnes/hour (can meet the demand of 100 tonnes)

Feed size: ≤50mm, discharge size: 3-35mm (adjustable)

Motor power: 2×90kW, low energy consumption (about 0.9 degree/tonne)

Advantage: compact structure, low maintenance cost, suitable for medium-sized sand plants with limited budget.

Hard materials (granite, basalt, river pebbles)

Recommended model: 2PGY1200×1000 roll crusher (hydraulic type)

Production capacity: 90-100 tonnes/hour
Feeding size: ≤55mm, discharging size: 1-5mm (hydraulically adjusted)
Motor power: 2×75kW
Advantage:

Hydraulic system automatically adjusts the pressure to adapt to the change of material hardness;
The roll surface adopts high-strength wear-resistant alloy, which extends the service life by 30%;
Less dust and noise ≤80dB, which meets the requirement of environmental protection.

High humidity/sticky materials (construction waste, steel slag)

Recommended model: 2PGY1000×1000 type roll crusher

Production capacity: 80-100 tonnes/hour
Feeding size: ≤180mm (large pieces of material are crushed directly)
Advantages:
No screen bottom design: completely solve the problem of wet material sticking and clogging;
Dual-stage crushing: one-stage coarse crushing + two-stage fine crushing, with 80% of the discharged material ≤3mm fine sand;
Suitable for hard-to-process materials such as steel slag, soil-containing river cobbles and so on.

2.Roller Crusher Price Reference

Price range:

Economic type (e.g. 2PG1200×1200): 100,000-150,000 RMB, suitable for projects with limited budget;
Hydraulic type (e.g. 2PGY1200×1000): 180,000-250,000 RMB, balancing the performance and cost;
High-end type (e.g. 1210 hydraulic): 250,000-400,000 RMB, including intelligent control system.

3. Suggestions for selection and guidelines for avoiding pitfalls

Priority trial machine:

Hard rock (granite) need to verify the wear resistance of the roll skin, and it is recommended to test the discharge size on site;
Wet materials (such as steel slag) need to test the anti-clogging effect.

Supporting equipment:

100 tonnes per hour complete production line needs to be configured:

Feeder (GZD900×3000) + Jaw Crusher (PE600×900) + Roller Host + Vibrating Screen (YK1545);
The total investment is about 400,000-600,000 RMB (excluding mobile).

Tips to avoid the pit:

Low price trap: equipment lower than 80,000 RMB may use common steel, and the roller skin life is only 3-6 months;
Environmental compliance: choose models with noise ≤ 85dB and dust cover (e.g. 1210 hydraulic type).
