In the field of sand and gravel aggregate processing, the double-roller sand making machine has gradually become one of the core equipment of small and medium-sized sand and gravel fields due to its high efficiency and energy-saving characteristics. Among them, the small double-roller sand making machine with a processing capacity of 10 tons per hour (10tph) is particularly favored by the market due to its compact structure and strong adaptability. This article will introduce the core value of this equipment in detail from three aspects: equipment characteristics, working principle and actual application scenarios.

1. Equipment characteristics and advantages

The 10tph small double-roller sand making machine is designed for small and medium-sized sand and gravel production lines. Its core structure consists of two parallel mounted rollers, which are driven by a motor to rotate in reverse to squeeze and crush the material. Compared with traditional sand making equipment, this model has the following significant advantages:

Energy saving and environmental protection: It adopts a low-speed and high-torque design, which reduces energy consumption by more than 30%. It is also equipped with a dust prevention device to reduce dust pollution.

Flexible adjustment: The gap between the rollers can be freely adjusted (usually 2-10mm), and the discharge particle size is uniform (0.5-5mm), which meets the requirements of sand material specifications for different projects.

Easy maintenance: The modular structure design simplifies the replacement process of wearing parts (such as roller skin), with short downtime and high production efficiency.

Strong adaptability: It can handle a variety of raw materials such as limestone, pebbles, and construction waste, with low moisture content requirements and a wide range of applicable scenarios.

2. Working principle

When the equipment is running, the material enters between the two rollers through the feed port and is crushed under the extrusion and shear force of the rollers. Sand with qualified particle size is discharged through the gap, and particles that do not meet the standard continue to be crushed by the rollers to form a closed loop. This process not only has high crushing efficiency, but also can control the crushing strength by adjusting the pressure of the hydraulic system to ensure that the finished sand has a rounded shape and low powder content, which meets the standards for construction sand.

3. Application scenarios and economic benefits

This model is widely used in small and medium-sized sand and gravel fields, construction sites and mine tailings recovery projects. For example, in a sand and gravel production line with an annual output of 300,000 tons, a single 10tph device can meet the production needs of 10 hours of work per day, with an investment cost of only 50,000-80,000 yuan and a short recovery period. In addition, its low noise (<75dB) characteristics also make it suitable for use in areas with strict environmental protection requirements around cities. A customer reported that after using this equipment, the sand material yield rate increased to 95%, and the comprehensive production cost decreased by 20%, which significantly improved the market competitiveness.

Conclusion

The 10tph small roller sand making machine has become an important tool for the transformation and upgrading of the sand and gravel industry with its high efficiency, flexibility and low consumption. With the growth of the country's demand for machine-made sand and the tightening of environmental protection policies, this type of equipment will play a more critical role in small and medium-sized sand and gravel fields, helping enterprises achieve green and sustainable development.
