How to choose different styles of sand making machine?

In the field of sand and gravel production, sand making machine is widely used in various industrial fields. Choosing the right sand making equipment directly affects the production efficiency, quality of finished products and operating costs.
In the process of mechanical sand processing, there are many types of equipment that can be used, impact sand making machine, composite sand making machine and roller sand making machine are the three mainstream equipment on the market at present, and each of them has unique advantages and applicable scenes.
So how to choose the sand making machine? In this article, we will compare and analyze the working principle and adaptive scenes.

Comparison of working principle

1.Impact Sand Making Machine

Impact sand making machine adopts the double-mode crushing principle of “stone hitting stone” and “stone hitting iron“, which represents the most advanced sand making technology at present. This kind of crusher is generally more powerful, of course, sand making efficiency is high, the sand rate is high, and the particle shape is good, so the application of the crowd is still quite wide. Because it is crushed by impact energy, so the impact sand making machine has a large power consumption.

2.Composite Sand Making Machine

Composite sand making machine adopts the principle of vertical composite crushing, combining the impact, extrusion and grinding of a variety of forces. Compared with the impact type sand making machine, high efficiency, high yield characteristics, composite sand making machine model is relatively small, stand-alone production capacity of 10-180 tons per hour, so the mountain weathered rock, or marl for the mechanism of sand, it is recommended that the use of this equipment, less investment, fast return.

3.Roller Sand Making Machine

The working principle of the roller sand making machine is the most intuitive, relying on the two opposing rotating rollers on the material extrusion crushing. However, due to the lack of impact, the sand produced by the roller sand making machine is usually high in needle and flake content, and the grading is not as ideal as the impact sand making machine, which can only meet the standard of Class II construction sand. Roller sand making machine mass production scale is limited, so it is not suitable for mass production line, of course, compared with the impact sand making machine, roller sand making machine is more energy-saving.

Comparison of Applicable Scenarios

Large sand farms basically consider impact sand maker, medium-sized sand farms impact sand maker and composite sand maker depending on the situation, for small, family-type workshops, the roller sand maker is the superior choice.
