Vertical roller mill for cement

Cement vertical roller mill refers to the roller mill used for in the production process of cement. In the 70s, vertical roller mills became increasingly dominant for grinding raw materials mainly for the cement industry due to their high energy efficiency and excellent drying capacity. Since the foundation day, Zenith knows how to combine our state-of-the-art technologies in the production of cement vertical roller mill. To our pride, every year, so many customers keep a great interest in the cost and price of vertical roller mill for cement. Here we focus on more details of cement vertical roller mill.

Overview of Cement Vertical Roller Mill

The typical cement vertical roller mill is designed to dry, pulverize, classify and deliver a number of different types of raw materials. From a feed ranging in size from approximately 10-44 mm, the roller mill can produce particles ranging from coarse, granular products of approximately 10%R2000 micron (90% minus 10 mesh) to as fine as 0.002%R44 micron (99.998% minus 325 mesh). They can also be used to prepare feed for systems producing ultra-fine materials. Cast and machined wear resistant steel roll is fastened to the tapered lower housing of the journal.

Vertical Roller Mill How to Work

Cement vertical roller mill made by Zenith is an air-swept vertical ring-roll mill with an integral classification system. A vertical shaft rotates a “spider” assembly of arms from which is suspended free swinging journal assembly with rolls attached. As the unit turns, centrifugal force drives the rolls against the inner surface of the vertical grinding ring. Plows, rotating with the assembly, lift feeding materials from the mill bottom and direct it between the rolls and the grinding ring where it is pulverized. The mill operates under negative pressure conditions, thus minimizing mill maintenance and plant housekeeping problems, while maximizing the service life of major mechanical components.

Technical Features of Cement Vertical Roller Mill

1. Quiet and Low-vibration Design

A design principle has been applied which is novel for flaking roller mills. It effectively suppresses vibrations generated in the rough flaking operation. Installation of the new flaking mill therefore does not require any special building-related measures. Its operation is quiet and smooth.

2. Unique Product Quality

The centrifugally cast rolls are provided with cooling circuits inside the roll jacket, which ensure a constant roll temperature across the entire roll width. The precision of the product feed system also has a decisive impact on the flake quality. All variants operate within a very narrow particle distribution range across the entire roll width.

3. High Ratio of Price and Performance

The price and cost of vertical roller mill for cement is very reasonable and attractive for cement producers. Besides, our cement vertical roller mill has different specifications, which are capable of producing a wide range of product fineness from a wide variety of materials.
