How to choose the right vertical sand mill & horizontal sand mill?
Sand Mill
Vertical sand mills and horizontal sand mills are commonly used equipment for grinding in paint, coating, ink, and other industries. They all rely on the high-speed rotation between the grinding medium and the material for grinding work.
Application: Paint, Adhesive, Battery, Pharmaceutical industry, Cosmetic
How to choose a suitable sand mill in the process of production and application?
Selection of vertical sand mill
As a kind of grinding machine equipment with high production efficiency, strong continuity, and low cost, the vertical sand mill has been widely used. In the face of today’s numerous vertical sand mill manufacturers, how to judge the quality of the equipment and make the right choice?
1. The material of the grinding barrel: In the sand mill industry, many manufacturers use stainless steel for grinding the barrel. There are also many kinds of stainless steel materials, which need to be confirmed by the owner.
2. The material of the grinding barrel rotor: In terms of the process of the sand mill, there are mainly two types, one is a disc-type grinding disc, and the second is a pin-type grinding barrel and a pin-type rotor. The grinding effect of the pin-type sand mill is much more obvious than that of the disc sand mill.
3. Separation device for materials and grinding mesons (zirconium beads): When separating materials and grinding media in a horizontal sand mill, a spacer separation device is mainly used. The spacer separation device is mainly composed of a static ring and a moving ring.
4. Cooling effect of mechanical seal and equipment: whether there is leakage of mechanical seal and how many hours of service life. The key is to see that the circulating fluid of the mechanical seal uses a solvent or water that is compatible with the grinding material, which avoids the accident of product contamination during production and brings unnecessary economic losses.
5. Production efficiency: Whether the structural design is reasonable or not determines the production efficiency and product quality.
6. Operation: The main control part of the machine is very centralized and easy to operate.
7. Easy to change color, clean, and replace zirconium beads: mainly to understand whether the grinding chamber is designed without dead ends and how effective the self-cleaning is.
8. Complete safety protection functions: the selection of electrical materials for the whole machine, quality, safety, etc.
Solutions of High Cycral Machine Temperatures
1. The temperature of the slurry at the pre -scattered stage is not high, but once the horizontal sand mill began, the temperature of the slurry in the grinding cavity exceeds the protection temperature, so that the sand mill was stopped. In the case, we can appropriately increase the speed of the feed pump, thereby shortening the stay of the slurry in the grinding cavity, so that the calories generated during the unit time will decrease, and the temperature of the sand milling pulp will be reduced.
2. The temperature of the grinding slurry must be controlled during the pre -scattered stage. If the temperature of the slurry is too high due to the long dispersing time, then the slurry can be cooled before the horizontal sand mill.
3. Sometimes the temperature of the horizontal sand mill is too high, or it may be too much grinding medium to fill, which can reduce the amount of grinding medium.
Selection of horizontal sand mill
The horizontal sand mill is a kind of grinding machine in the coating production process. It belongs to non-standard customized equipment. This equipment can customize horizontal sand mills with different configurations according to different needs of customers to meet production needs.
The configuration of the horizontal sand mill is various. The material of horizontal sand mill can be divided into two kinds of materials, one is carbon steel horizontal sand mill, and the other is stainless steel horizontal sand mill. If it is distinguished according to the conditions of use and requirements, the horizontal sand mill can be divided into two types of motors, one is an explosion-proof motor horizontal sand mill, and the other is an ordinary motor horizontal sand mill. According to the structural form, horizontal sand mills can be divided into ordinary horizontal sand mills, wheel pin horizontal sand mills, gear plate horizontal sand mills, and turbine horizontal sand mills. There are many models to choose from to configure the horizontal sand mill according to different requirements.
The horizontal sand mill can continue to work without interruption during production and use and has a very high work efficiency. The performance characteristics of the horizontal sand mill are very prominent, its self-control performance is very good, and the pollution to the environment during operation is also reduced to the minimum. The structure of the horizontal sand mill is carefully designed and compact, and the appearance is beautiful and durable. The cost is still very low, it is very cost-effective grinding equipment, it is easy to use and maintain, and it is very practical.
The difference between horizontal sand mill and vertical sand mill
1. From the difficulty of manufacturing. Since the vertical sand mill avoids the problem of sealing, it is easier to manufacture and the cost is lower. On the contrary, the manufacturing cost of the horizontal sand mill is relatively high, so the cost is relatively high.
2. From the aspect of grinding fineness. After the grinding medium in the grinding chamber of the vertical sand mill is affected by gravity, the filling rate of the medium is low, and the distribution is not uniform, which makes the grinding effect unsatisfactory. However, the horizontal sand mill can well overcome the influence of gravity on the medium, so it has a better grinding effect and can meet the fineness requirements of the product.
3. From the cost of use. When the vertical grinder is shut down, the grinding medium is at the bottom of the grinding chamber. Then, as soon as the machine is turned on, the blades will have strong friction with the beads. Because the grinding beads are too concentrated, it is easy to cause the bead breaking incident. However, the horizontal sand mill is placed horizontally, which greatly reduces the broken rate of grinding beads.
4. In terms of material. Vertical sand mills generally use ordinary materials, while horizontal sand mills generally use better materials. Generally, the materials used in horizontal sand mills are tungsten carbide metal materials.

Guidelines For Sand Mill
The sand mill mainly uses friction, shearing, and collision as effective grinding methods. It is one of the grinding equipment currently applicable to a wide range of material particle sizes and has high grinding efficiency. The energy density per unit volume is large. The control system can complete the continuous grinding and continuous discharging of the slurry, which greatly improves the production efficiency of the sand mill. It has the advantages of high energy density, fine product granularity, small environmental pollution, simple equipment structure, and convenient maintenance.
