What Is Cement Vertical Mill

The cement vertical mill is a type of grinding equipment that merges fine crushing, drying, grinding, and powder separating into a single, which simplifies the production process and has many irreplaceable advantages, such as high grinding efficiency, large feeding size, low power consumption (20-30% less power than a cement ball mill), large drying capacity (simultaneously dry and grind materials with moisture up to 10%), simple grinding process, small floor area, low noise, long service life, low operation cost, etc. It uses a hydraulic system to generate pressure act on the material (0-44mm) between the roller and the grinding disc to achieve the purpose of grinding.

AGICO, as a cement equipment manufacturer in China, offers different types of vertical mills like coal vertical millsraw material vertical mills, cement vertical mills, and slag vertical mills. Our AG cement vertical mill, based on advanced technology, is a reliable and affordable cement mill. With the same rotational speed, grinding disc diameter, material layer, and grinding roller pressure, the grinding efficiency of the AG vertical mill can be increased by more than 30%, with an average energy saving of 8.2%. The overall impact and vibration of the machine are significantly reduced.

Cement Vertical Mill Structure

Transmission Device

The transmission device consists of three parts: the main motor, coupling, and reducer, which are installed at the bottom of the mill. This device not only drives the grinding disc but also supports the weight of the grinding disc, materials, grinding rollers, and the grinding pressure applied by the hydraulic system.

Grinding Device

The grinding device consists of the grinding disc and grinding rollers, which are crucial components for milling. The design of their shape must ensure that the material being ground forms a uniform and stable thickness on the grinding disc.

Hydraulic Device

It uses hydraulics to apply force to the material. We can adjust the pressure according to the grindability of the material, ensuring that the mill operates under the most economical conditions. Due to the cushioning effect of the accumulator, the pressure applied by the hydraulic cylinder is quite flexible.

Classifier

The classifier’s speed is adjustable, and the high-speed rotation of the rotor separates coarse particles from fine particles. Fine particles pass through the gaps between the classifier blades and are collected by the dust collector.

Lubrication System

It includes an oil station, pipelines, and various valves. The oil station is divided into the motor oil station, high and low-pressure oil station for the reducer, classifier oil station, and grinding roller lubrication oil station.

Inhibiting Device

The inhibiting device allows the mill to start under a light load. The gap between the grinding roller and the grinding disc is adjustable, which ensures a stable material layer thickness, improves grinding efficiency, and also ensures that the grinding roller and grinding disc do not direct contact in abnormal situations such as material interruption, thus protecting the reducer.

Cement Vertical Mill Features

The cement vertical mill has a simple technological process, a compact layout, and a small building area. It covers an area of about 70% of the ball mill and it can be arranged in the open air, which directly reduces the investment cost. The vertical mill itself has a classifier, without additional powder concentrator and lifting equipment. Dust can be collected directly by a bag filter or electrostatic precipitator.

The cement vertical mill has low energy consumption. The power consumption of its grinding system is about 20%-30% lower than that of the ball mill, and this power-saving effect is more obvious with the increase of raw material moisture. In addition, the vertical mill adopts a fully enclosed system, which works under negative pressure, without dust, and has a clean environment.

This equipment is equipped with an automatic control system, which can realize remote control and is easy to operate. By overhauling the cylinder, the roller sleeve and liner can be replaced conveniently and quickly, and the loss of shutdown can be reduced.

In the process of operation, there is no direct contact between the roller and the grinding disc, so the wear is small. The metal consumption is generally 5~10g/t.

Regardless of whether uses center feeding or side feeding, the material can evenly fall into the center of the grinding disc. In addition, it employs the latest dynamic and static classifiers, ensuring high powder-separating efficiency.

The equipment utilizes 3-4 tire-shaped or conical grinding rollers, paired with specially structured material-blocking rings and scrapers. The surfaces of the grinding rollers and grinding disc liners are made of wear-resistant surfacing materials, ensuring high grinding performance and extended service life.

The hydraulic tensioning system of the cement vertical mill adopts a cylinder arm plus a rocker arm structure. Each set of grinding rollers can use an independent pressure system during pressurization. The rocker arm features a special safety design to maintain a specific gap between the grinding rollers and the grinding disc, ensuring equipment safety during maintenance and in case of accidental operation.
