Comparison of the vertical sand mill and horizontal sand mill
According to the layout of the grinding drum, it can be divided into vertical sand mills and horizontal sand mills. These are two very common styles. Next, we will learn more about the characteristics, advantages, and working principles of the two sand mills.
The vertical sand mill is mainly composed of a feed system, grinding drum, grinding disc, transmission, and electric control system.
Working principle of vertical sand mill
Vertical sand mill VS horizontal sand mill
• Manufacturing difficulty
In terms of manufacturing difficulty and manufacturing cost, vertical sand mills have more advantages. In addition, the vertical sand mill does not take up space, and the operation is very convenient, which is suitable for materials with various viscosities. If you have a small budget or do not have high requirements for the fineness of the material, the vertical sand mill will be a very cost-effective choice.
• Grinding fineness
The grinding medium (beads) in the vertical sand mill is affected by gravity and tends to accumulate to the bottom of the grinding cavity, resulting in a less uniform particle size distribution of the ground material, resulting in a better grinding effect at the bottom than at the top. This is like a bucket of stones, the stones on the bottom of the bucket are ground finer than those on the top of the bucket.
The horizontal sand mill can well overcome the influence of gravity on the medium. Because the feed of the horizontal sand mill is generally from the left to the right, the grinding force of the material in the barrel is the same, the particle size distribution of the output material will be more uniform, and the grinding fineness is generally up to 1μm.
• The cost
• Scope of application
At present, sand mills are developing in the direction of large batches, refinement, high purity, and low energy consumption. Equipment maintenance is the key to extending the life of mechanical products, and it is also related to the stability and efficiency of production. Understand the common faults of sand mills and their solutions to reduce production losses caused by unnecessary equipment downtime.

This kind of butterfly mixer is used in offset ink, putty etc industry. The butterfly dispersing mixer is a product with the functions of dispersing and stirring (wall scraping) developed on the basis of a single-axis hydraulic lifting disperser.
TRS-Three Roll Mill For Lipstick
TRS Three roll mill is widely used in milling paste material including paint, inks, China ink, pigment, coatings, food, cosmetics, and so on.
Ceramic Three Roll Mill
The ceramic three roller mill mainly uses the surface of three rollers to grind and disperse at different speeds to make the ground material reach the required grinding fineness. The three roller mill is suitable for the grinding of ink, paint, paint, lipstick, chocolate, soap, and other materials, and it is mainly composed of a roller, a machine base, a guide cover, a discharge knife plate, a feeding copper knife, a cooling system, etc. The fineness of the material grinding can be adjusted by the screw on the base.
