The double-roll sand-making machine, as a classic crushing device, is renowned for its durability, efficiency, and energy savings. Its main models include the spring series, hydraulic series, and reinforced series, each designed to meet different production requirements. These machines feature a double-roll structure, allowing the output particle size to be controlled by adjusting the distance between the two rolls, making them suitable for materials of various hardness levels. Their unique wear-resistant materials extend service life and reduce maintenance costs. Prices vary depending on the model and configuration, ranging roughly from several thousand to several hundred thousand RMB.

1. Core Advantages: Why Choose a Double Roll Crusher?

Precise Particle Size Control

By hydraulically or mechanically adjusting the distance between the two rolls (typically adjustable from 30 to 200 mm), the output particle size is uniform and controllable, reducing over-crushing rates by over 30%, with cubic particle content exceeding 80%, meeting the gradation requirements for construction aggregates.
Compared to traditional jaw crushers or hammer crushers, the finished product has a more concentrated particle size distribution, reducing subsequent screening costs.

High Efficiency, Energy Saving, and Cost-Effectiveness

The double-roll compression crushing principle has low energy consumption, with a power consumption of only 0.5–0.8 kWh/tonne, achieving energy savings of 30–50% compared to impact crushers.

Modular wear-resistant tooth rollers (made of high-chromium alloy) have a service life of over 8,000 hours, with maintenance costs 30% lower than those of jaw crushers.

Strong adaptability and environmental friendliness

It can process medium to low hardness materials (compressive strength ≤70 MPa), such as limestone, shale, and coal gangue, and supports wet sticky materials with moisture content ≤15%.

The enclosed structure reduces dust emissions by 60%, with noise levels below 85 dB, meeting green production standards.

Safety and Intelligence

Hydraulic overload protection automatically retreats upon encountering hard objects to prevent equipment damage; integrated metal detectors prevent rebar blockages.

The intelligent control system adjusts parameters in real-time to achieve automated production (requiring only 1-2 operators for monitoring).

The double-roll sand-making machine can process various types of minerals, rocks, and construction waste materials. Its powerful pressure can crush large pieces of material into small particles or powder of the desired specifications. For example, hard minerals such as iron ore and copper ore can be processed by the double-roll sand-making machine to produce finely crushed materials suitable for smelting or other processing requirements. For soft rocks like limestone and gypsum, it can also achieve efficient crushing to meet the requirements of building materials. This makes it widely applicable in fields such as mining and building materials production.

Double-roll sand-making machines are classified into large, medium, and small sizes based on their models.

1. 2PGT400×250, 2PGT400×400, 2PGT610×400, with an hourly output of approximately 2-20 tonnes, belong to the small-sized spring double-roll sand-making machine category, suitable for investment and use in small and medium-sized sand plants.

2. 2PGT750×500, 2PGT800×600, with an hourly output of 10-50 tonnes, are medium-sized spring-type double-roll sand-making machines. This model is suitable for new sand plants with relatively low investment costs.

3. 2PGY750×500, 2PGY800×600, 2PGY800×800, 2PGY1000×800, with an hourly output of 20-80 tonnes, are medium-sized hydraulic double-roll sand-making machines. Hydraulic models are more intelligent, have higher output, and are more cost-effective.

4. 2PGY1000×1000, 2PGY1200×1200, 2PGY1500×1000, 2PGY1800×1000, 2PGY2000×1000, with an hourly output of 80-400 tonnes, belong to the large-scale flagship series of CNC double-roll sand-making machines, suitable for medium to large-scale sand plants. They feature one-button start/stop for convenience and efficiency.
