How is the sand making effect of roller sand making machine?

From the sand making effect, the roll sand making machine has obvious advantages. The size of the sand produced is uniform, and the shape of the particles is regular, which meets the high requirements of modern construction for the quality of sand. Roller sand making machine has a high sand output rate, which can greatly improve the efficiency of ore use. The production process is relatively environmentally friendly, reducing dust pollution and noise pollution.

1. Core advantages of the sand making effect of roller sand making machine

Uniformity of particle size and finished product quality

Roller sand making machine adopts the principle of extrusion crushing, the discharged material is concentrated in the 1-3mm range.? The particle size distribution is uniform, and it meets the standard of construction sand. The finished sand has low needle flake content, smooth particle surface, no internal cracks, and improved concrete strength.

High rate of sand formation: the rate of sand formation in some cases (e.g. processing pebbles) can reach 95%, which is much higher than that of impact sand making machine.

Optimisation of particle size

After squeezing and grinding medium hardness materials (such as limestone and guamite).? It can significantly improve the grain shape and enhance the fluidity of construction sand. Roller sand making machine can further reduce the needle flake particles through ‘stone grinding stone’ layer crushing.

2.Capacity and efficiency performance

Processing capacity

Wide range of capacity (3-110 tonnes/hour), suitable for small and medium-sized production lines.

Energy consumption and sand output rate

Compared with the impact sand making machine, the energy consumption is 20%-30% lower, and the output can be increased by 30%-40%. The sand output rate depends on the material control:

The best effect is when the feed size is ≤25mm; limestone sand needs to control the water content to avoid sticking, which leads to the decrease of sand output rate.

3. Applicability and environmental performance

Material adaptability

It is good at processing medium hardness materials (such as limestone, coke, guamite), and has limited effect on high hardness rocks (such as granite). The feed size should be ≤150mm, and large materials need to be pre-crushed.

Environmental protection design

The airtight structure with dust removal system effectively suppresses dust pollution and meets the requirements of environmental protection. Low noise, improve the working environment.

4.Economic Benefits and Maintenance Costs

Roller sand making machine has compact structure, small footprint and low investment cost. High chrome alloy roller skin, the service life can reach 1000-3000 hours, the wear resistance is better than the hammer head type sand making machine.The hydraulic system supports automatic pressure adjustment and easy maintenance.

Roller sand making machine has outstanding performance in small and medium-sized production line, especially suitable for processing medium hardness materials such as limestone, guamite, etc., with the core advantages of high sand formation rate, low energy consumption and easy maintenance. If pursuing high capacity or handling very hard materials, it should be matched with other equipments (e.g. jaw pre-crushing, impact crusher shaping).
