Roller Sand Making Machine: Medium And Fine Crushing Energy Saving Expert, Help Sand And Gravel Precise Particle Control

With the core principle of “double-roll extrusion crushing”, the roller sand making machine has become the preferred equipment in the field of sand making for medium and low hardness materials by virtue of its advantages of low energy consumption and low over-crushing rate. Its advantages include:  

1. precise grain control: by adjusting the roll spacing (2-10mm), it can directly produce 0-5mm sand with uniform grain size and <10% needle flake content, which is suitable for high standard concrete aggregate;  

2. Economical and durable: the roller surface adopts high manganese steel or composite wear-resistant material, which enhances the service life by more than 50% and reduces the maintenance cost by 30% compared with that of the impact crusher;  

3. environmental protection and low noise: closed structure combined with circulating air dust removal, dust emission <15mg/m³, operating noise ≤ 75dB, to meet the requirements of green mines.  

In the mining crushing industry, rollers are widely used in the fine crushing of limestone, gangue and other hard materials. For example, in the limestone production line, the jaw crusher completes coarse crushing (crushing 1m raw stone to below 200mm), and the roller machine relay fine crushing to 0-5mm sand, sand yield up to 90%, and controllable stone powder content, which can be directly used in the production of dry-mixed mortar, reducing the energy consumption of the screening process.
