Material grinding machinery

■Application

■Summary

This series of hydraulic cylinders is mainly used for Germany's Loesche cement vertical mill equipment and Hedeke coal mills. Each hydraulic cylinder is equipped with enough accumulators to ensure the minimum fluctuation of roller pressure during vertical mill operation so as to make the mill run smoothly; between the roller sleeve and the hub, and between the roller shaft and the rocker arm respectively. Surface structure and expansion sleeve structure connection, convenient disassembly
■Features
● Fixed work stress：16MPa；
● Design temperature: The general use temperature does not exceed 80°C, and can be adjusted according to the actual working conditions.
● Sealing system
The main seal adopts MERKEL's ES type combination seal, which is used for multiple seal groups of the piston rod. It consists of a pressure ring and at least 3 V-rings and a support ring. The seal can adapt to the requirements of a rugged and harsh operating conditions, long service life, can be the best adjustment, combination to adapt to a variety of corresponding the use of.
● Piston rod
42CrMo forgings were used as raw materials and subjected to secondary flaw detection and corresponding heat treatment. The intermediate surface was quenched with intermediate frequency and chrome-plated and polished to make the surface hardness and roughness up to the relevant standards.
● Cylinder block

The cylinder body is made of low-alloy high-strength structural steel. The inner surface of the company's cylinder body, which has been manufactured with the appropriate strength and suitable dimensions, has been chrome-plated to achieve a good surface roughness and roughness, improving wear resistance.
