Industry Leading Manufacturer of Vertical Roller Mills
With many years of experience in technical innovation within the field of cement and slag grinding, CITIC Heavy Industries (CITIC HIC) has successfully developed various models of vertical roller mills. Our team of experts will help global customers develop a reliable, energy-saving and high-efficiency vertical roller mill grinding solution by taking advantage of our technological development strength, core manufacturing expertise, strict quality control measures and excellent customer service.
Core Advantage
At our powerful national key laboratory, CITIC HIC has established a vertical roller mill testing platform to conduct trials and tests of different materials, thus identifying the best solution of vertical roller mill selection.
Our engineers employ FEA software to analysis, calculate and optimize the structural strength of grinding roller shaft, rocker arm, grinding table and other key components, ensuring the high reliability of machine operation.
- Fluid flow
-
A professional fluid flow simulation software is adopted to analyse fluid flows and optimize the internal structure of vertical roller mill.
- Transmission
-
The large vertical planetary gear reducer was developed using state-of-the-art technology. With a construction of one bevel gear stage and two planetary gear stages, the gear unit features high transmission accuracy, uniform stress distribution and high load bearing capacity. The gearbox service factor is greater than 2.5 in accordance with AGMA standard.
- Classifier / separator
-
The dynamic classifier is integrated in the VRM mill, providing high accuracy, high efficiency, low pressure drop and low energy consumption.
- Control
-
The advanced control system performs real-time monitoring of operating parameters. A touch screen display is configured for easy control, enabling the machine to be operated highly automatically, continuously and stably.
- Full-process solution
-
Equipment design → Project design → Equipment configuration → Installation & commissioning through to turnkey project acceptance sign off
