The vertical mill cylinders are working under harsh conditions: the dust and gravel act a strong abrasion effect on the piston rod, and vibration and shock during operation require extremely excellent cylinder fatigue life.

Haite developed vertical mill cylinders possess outstanding performance: the chromium plating on the cylinder barrel inner wall provides a high wear resistance and greatly improves the cylinder service life under continuous operation. Measures as adoption of high-strength forging materials,high-frequency surface quenching,structure optimization through finite element method (FEM) are implemented to reduce stress concentration.
