Roller crusher shows significant advantages in the application of crushing concrete sand, which is reflected in the following aspects:

Precise particle size control, high quality of finished products

1. Discharge uniformity:

Through the crushing method of double-roll extrusion and grinding, the discharge particle size (usually 1-5mm) can be precisely controlled to meet the high requirements of concrete sand on particle shape and gradation.

2. Reduction of over-crushing:

Roller Crusher Compared with hammer crusher, its crushing process is gentler, effectively reducing the proportion of powdery materials (the rate of pulverised minerals is as low as less than 10%), avoiding the high content of impurities in sand and gravel, and improving the strength of concrete.

3. Optimisation of grain shape:

The output sand grains are cubic, with smooth surface and reasonable grading. Which can enhance the fluidity and compactness of concrete.

High energy efficiency and low operating cost

1. High crushing efficiency:

The synchronous rotating design of double rollers can achieve continuous crushing and large processing capacity (4-400 tonnes per hour), which is suitable for large-scale sand and gravel production line.

2. Low energy consumption:

The extrusion crushing method saves 30%-50% energy compared with impact equipment, and the hydraulic system supports intelligent adjustment to further optimise energy consumption.

3. Low maintenance cost:

Modular design and wear-resistant roller skins (life expectancy of up to 2-3 years) reduce the frequency of replacement of wearing parts, and daily maintenance only requires lubrication and gap adjustment.

Environmental protection and adaptability advantages

1. Dust and noise control:

Closed structure and low-impact crushing principle significantly reduces dust dispersal, and the noise is lower than 85 decibels, which is in line with green production standards.

2. Wide material adaptability:

It can deal with a variety of materials such as concrete blocks, construction waste, hard rocks (e.g. granite, basalt), etc., and crushes both dry and wet materials.

3. Flexible and adaptable scenes:

Suitable for sand and gravel plants, concrete mixing stations, construction sites and other scenes, supporting the transformation of old plants and the construction of new production lines.
