Crushers and Wear-Resistant Components
Double Roll Crusher – Efficient Crushing Solution for Medium-Hard Materials
-
Working Principle
-
Materials fall into the gap between two rotating rolls from the feeding port. Through extrusion, the materials are crushed, and the finished products naturally drop. When encountering overly hard or uncrushable materials, the rolls automatically yield via hydraulic cylinders or springs, increasing the gap to let the materials pass—protecting the machine from damage. By adjusting the gap between the two oppositely rotating rolls, you can precisely control the discharge particle size.

Main Features
- 1.Easy Discharge Adjustment: A wedge device with adjustment bolts allows quick control over the roll gap. Raising the wedge increases the gap for larger particle discharge; lowering it reduces the gap for finer particles.
- 2.Stable Drive System: Driven by two electric motors, a three-angle belt transmits power to the rolls, ensuring opposite-direction rotation. Materials enter from the feed port, are crushed by the rolls, and exit from the bottom.
- 3.Durable & Safe Design: The transmission part uses high-quality wear-resistant materials (especially the grinding rolls, which are reusable), extending service life. Safety covers can be installed per user needs, reducing failure rates.
- 4.Energy-Efficient & High-Quality Output: By lowering feed particle size and improving material quality, it achieves multi-crushing and grinding, optimizing product shape, enhancing crushing capacity, and delivering high output with low energy consumption.
