Product overview
Corundum roller crusher is a type of roller crushing or grinding equipment that uses corundum as a key component wear-resistant layer. It is usually used to process minerals or materials with high hardness such as corundum, silicon carbide, quartz, etc.
Basic structure
Roller: The surface is covered with a corundum layer (such as sintered corundum or ceramic coating) to enhance wear resistance.
Transmission system: Driven by a motor, it drives two rollers to rotate towards each other through a reducer, gear, or belt.
Adjustment device: manually or hydraulically adjust the roller spacing to control the discharge particle size.
Safety device: Spring or hydraulic buffer to prevent overload damage to equipment.
Working principle
The material enters the gap between the two rollers from above and is crushed by compression, shearing, and grinding.
The high hardness (Mohs hardness 9) of the corundum roller surface can effectively reduce wear and extend its service life.
Main advantages
Strong wear resistance: suitable for crushing high hardness materials such as quartz, silicon carbide, and corundum sand.
Particle size control: By adjusting the roller spacing (usually 0.1-5mm), uniform finished particles can be obtained.
Low pollution: Corundum material has good chemical stability, avoiding metal pollution, and is suitable for industries such as ceramics and electronic materials.
Application area
Mining: fragmented quartzite, granite, iron ore, etc.
Refractory materials: Processing raw materials such as corundum sand and silicon carbide.
Ceramics/Glass: Preparation of high-purity powders (such as feldspar and kaolin).
Environmental Protection: Processing hard recycled materials such as waste glass and electronic waste.
Selection and maintenance points
1. Selection parameters
Material hardness (recommended Mohs hardness ≤ 9), feed particle size (usually ≤ 30mm), processing capacity (0.5-50 tons/hour).
2. Maintenance suggestions
Regularly inspect the wear of the roller surface and promptly repair or replace it.
Prevent metal foreign objects from entering and prevent the roller surface from cracking.
Lubricate the bearings to maintain the stability of the transmission system.
