In this product introduction, we'll summarize the features and benefits of our Vertical Stirred Mill and present why it is an ideal grinding solution for merchants looking to enhance their operations.

What is a Vertical Stirred Mill?

The Vertical Stirred Mill, also known as a Stirred Media Detritor (SMD), is a revolutionary grinding device that utilizes gravity, energy, and grinding media dynamics to deliver ultra-fine grinding performance. The mill consists of a vertical cylindrical shell with a centrally located agitator shaft. The agitator utilizes impellers or grinding discs to stir the media, generating high-intensity grinding forces that ensure homogeneous and fine grinding of the material.

Unlike conventional mills, the Vertical Stirred Mill also employs gravity to move the media in a circular path around the agitator shaft, ensuring efficient grinding with no energy-intensive recirculation pumps or external heat sources. This mechanism lowers the energy consumption required to operate the mill, leading to significant cost savings for end-users.

What are the benefits of using a Vertical Stirred Mill?

1. High grinding efficiency

The Vertical Stirred Mill's unique grinding mechanism ensures a high level of grinding efficiency for even the most complex and challenging materials. The mill can achieve fine grinding up to 10 microns and reduce energy usage by up to 40% compared to traditional grinding systems. This results in a significant reduction in operating costs.

2. Low maintenance

The Vertical Stirred Mill is designed for easy maintenance and long service life. Its compact design ensures simple installation and replacement of components, while the absence of external heat sources minimizes wear and tear, reducing maintenance costs significantly.

3. Versatility

The Vertical Stirred Mill can be used for a wide range of applications, including primary grinding, secondary grinding, regrinding, and ultra-fine grinding of various minerals and materials. It is ideal for industries such as mining, cement, chemicals, and others.

4. Minimal environmental impact

Vertical stirred mill, also called tower mill, is a new type of high-efficiency and energy-saving wet grinding mill newly developed by our company. There is a spiral agitator in the cylinder, and it is filled with grinding media.

During the rotation of the spiral agitator, the grinding medium produces continuous extrusion, shearing and peeling effects on the material.

The contact area between the grinding medium and the material is large, the grinding intensity is high, and the power consumption per unit product of the tower mill is greatly reduced.

The energy-saving effect reaches more than 30%, which greatly reduces the production cost.

Our tower mills are designed for low speed, heavy load, high reliability, and long life.

The slurry concentration and product particle size can be adjusted and responded quickly within a certain range, and are suitable for mineral materials with different hardness, viscosity, and grindability. Strong capacity, which greatly improves the ability of the tower mill to process different materials.

It can effectively reduce the customer's installation cost and use cost, and significantly improve the benefits of the concentrator. At the same time, it also has the advantages of small footprint, simple equipment foundation, and convenient installation and maintenance.

Application fields: Widely used in metallurgy, metal mining, building materials industry, environmental protection industry, etc.

1. The new feed is first fed into the pump pool before the hydrocyclone, fully mixed with the discharge from the tower mill and the water supply from the main water tank in the pump pool, and after reaching the slurry concentration required by the process, it is sent into the pump pool by the slurry pump The hydrocyclone performs particle size classification, and the finer materials that meet the particle size requirements of the process are discharged from the overflow port of the hydrocyclone into the next process equipment, and the coarser materials that do not meet the particle size requirements of the process are discharged from the grit outlet of the hydrocyclone and returned To the feed port of the tower mill.

2. The material from the hydrocyclone is fed into the tower mill from the position of the feed inlet of the tower mill. When the motor drives the spiral agitator to rotate at a constant speed through the reducer, the grinding medium and the material are subjected to centrifugal force, drag force and friction force, combined with gravity.

3. Macroscopically, the slurry and the steel ball make regular circular motion, which is manifested as a spiral rising between the screw lifting speed and the slurry conveying speed inside the scope of the stirring spiral projection area, and in the annular area outside the scope of the stirring spiral projection area, the inner fluid spirals upward, and the outer fluid spirals downward.

The upward mainstream and the downward countercurrent are formed in reverse contact, forming a vortex, resulting in boundary layer separation.

4. Microscopically, due to the unbalanced force between the grinding medium and the material, the velocity gradient between the fluid layers is formed, so that the combined effects of local shear force, extrusion force and impact force are generated between the material and the material, and between the material and the steel ball. To achieve the effect of fine grinding.

5. After grinding, the fine-grained materials smaller than the cutting particle size rise with the slurry flow, and the coarse-grained materials larger than the cutting particle size are circulated back to the bottom of the mill for a new round of grinding to achieve the purpose of gravity classification inside the tower mill. Overgrinding and agglomeration of particles are greatly reduced.
The internally classified slurry overflows from the discharge port of the tower mill located on the upper body into the pump pool, thus forming a closed-circuit grinding of the material.
