How is the effect of the roller sand making machine in hitting river pebbles

Roller sand making machine is a mining machine that utilizes two opposing rotating rollers to crush the material, simple structure, low operating costs, able to produce both stone and sand, suitable for brittle, medium hardness materials, of which the river pebbles in the rock is more familiar and common a purely natural stone, so how is the effect of the roller sand making machine to hit the river pebbles?

From the finished product particle size, quality, various technical indicators, the effect is still good, river pebbles is a hard texture, wear-resistant, chemically stable silicate minerals, the main chemical composition is silicon dioxide, Moh's hardness 5-7, and the roll sand making machine is just suitable.

Cobblestone roller sand making machine work by extrusion friction, the strong pressure generated between the two rollers extrusion crushing, large feed size, the surface of the rollers have uneven teeth, can be processed in depth, so the finished product rate is increased, the crushing ratio is large, generally can be crushed to 2-10mm size, good particle size, uniformity, low over-crushing rate, and at the same time, the use of new high-strength wear-resistant materials, in the crushing of high-hardness materials, small losses It has a long service life.

The pebbles through the feed port into the two rollers between the extrusion crushing, finished materials fall naturally, in the event of hard or unbreakable material, the rollers can be with the role of the hydraulic cylinder or spring automatically give way, so that the rollers gap increases, hard or unbreakable material falls, so as to protect the machine from being damaged, rotating in the opposite direction of the two rollers have a certain gap, change the gap, you can control the product larger discharge particles.
