Double Roll Crusher / Two Roller Crusher
Double roll crusher, also named roller crusher, adopts double rollers extrusion crushing principle. It is widely used for medium and fine crushing of medium-hard and brittle materials. The machine is divided into smooth roll crusher and toothed roll crusher according to roller surface type, featuring uniform finished particle size, adjustable discharge opening, low dust and low over-crushing rate, ideal equipment for sand making, coal crushing and mineral processing.
Core Advantages of Double Roll Crusher
- Stable Extrusion Crushing: Less powder generation, uniform round finished aggregate, meet high-standard sand requirements
- Two Optional Roller Types: Smooth roller for fine crushing hard stone; toothed roller for coarse crushing coal, shale, slag
- Adjustable Discharge Size: Hydraulic spring buffer device, quick gap adjustment to control output granularity
- High Wear-resistant Roller Shell: Made of high manganese alloy, long service life, easy to replace spare parts
- Anti-blocking Structure: Optimized feeding bin design, effectively solve material clogging problem of sticky wet raw materials
- Energy Saving & Low Noise: Simple transmission structure, low power consumption, closed body for dust suppression
- Small Floor Space: Compact whole machine, convenient for fixed crushing line and mobile crushing station matching
Suitable Crushing Raw Materials
