Grinding Performance

The 98 mm premium cast steel burrs are designed to provide excellent particle-size distribution and consistent grinding across multiple brewing applications. The EK43 platform supports applications including filter, espresso and Turkish fine coffee, although the standard 703804 burr geometry is intended for general/standard grinding rather than the dedicated Turkish-fine configuration.

The EK43 S Allround platform has an average grinding capacity of approximately 19–21 g/s, depending on the grinding product and selected fineness.

When to Replace EK43 Burrs?

Consider replacing the burrs when you notice:

• Inconsistent particle size
• Reduced grinding speed
• Increased grinding time
• Difficulty achieving the desired grind setting
• Changes in coffee extraction or flavor consistency
• Visible burr wear or damage
• Excessive burr retention or inconsistent dosing
