Frequently Asked Questions
In today’s sand mill market, as the most widely used high-end refined powder grinding equipment, each has its structural design and improvement, especially the design of the dispersing disc, which is even more diverse, but it is the layout of the grinding cylinder. In terms of form, it is mainly divided into horizontal and vertical.
The development of sand mills has probably gone through the following stages:
The first stage: vertical stirring mill (bottom screen separator + rod type grinding original);
The second stage: vertical disc sand mill (disc + top screen separator);
The third stage: Vertical pin sand mill (rod type + top gap separator);
The fourth stage: horizontal disc sand mill (disc + dynamic rotor centrifugal separator);
The fifth stage: horizontal pin rod circulating sand mill (rod type + super large filter area separator).
The invention of the vertical sand mill improves the shortcomings of the vertical agitating mill such as low rotation speed, large media size, low grinding efficiency, and wide product particle size distribution so that the grinding equipment market has completely entered the era of sand mills.
However, due to the structural limitations of the early vertical sand mills, there were some problems, such as the low filling rate and uneven distribution of the grinding media under the influence of gravity. After avoiding these shortcomings, it quickly squeezed the market and gradually became the mainstream of fine grinding equipment.
But this does not mean that the vertical sanding machine will be replaced. There is still room for optimization and it has its unique advantages. Compared with the traditional horizontal sand mill, the vertical sand mill with this structure design can effectively solve the leakage of shaft seal damage, the blockage of the bead grading network, the inability to grind with ultra-fine beads, the uneven product particles, and the low production efficiency. The five major problems of high consumption.
How to solve the shortcomings of traditional vertical and horizontal sand mills through structural optimization and improvement?
- Feeding and discharging materials are different from traditional horizontal machines. The feed is conveyed to the grinding cavity by driving the screw thread, and the material is extracted from the grinding cavity by the suction of the pump when the material is discharged. No additional mechanical seal is required, and the leakage and pollution problems caused by the damage of the shaft seal are prevented from the root cause.
- The grinding process makes full use of the principles of centrifugal classification and fluid mechanics. The grinding chamber is divided into two grinding zones inside and outside by the stirring rotor, inner stator, and classification turbine. The raw material particles will undergo centrifugal classification inside for classification and grinding, and the materials and beads are also separated by centrifugation.
- The grading cycle grinding enhances the grinding effect. The material first enters the outer grinding zone and moves along the outer grinding void between the rotor and the cylinder along with the beads. After reaching the bottom, it moves along the inner grinding zone between the rotor and the inner stator to near the axis and then moves there. The role of two classifications. Finally, the small particles are discharged to the outer circulation cylinder in time, and the large particles are discharged to the outer grinding area to continue to participate in the next grinding cycle, which not only prevents the over-grinding of the small particles, but also increases the grinding times of the large particles, and the final product size The distribution span is small.
This method of centrifugal force classification solves the problem of screen clogging, and the classification grinding also effectively utilizes vertical gravity to allow the raw material particles to circulate up and down inside, lengthening the grinding channel and also allowing the particles to be more uniformly dispersed. Better grinding effect. In the whole grinding process, the equipment energy is mainly used for the effective grinding of large particles, which maximizes the useful work of the equipment, realize high-efficiency and energy-saving grinding, and improves the grinding efficiency of the equipment.

Guidelines For Sand Mill
The sand mill machine adopts the eccentric disc grinding structure and is arranged in a certain order. This system overcomes the shortcomings of the uneven distribution of the grinding media of the traditional grinding machine so that the grinding media can get the maximum energy transfer and the grinding efficiency is high.
The energy of grinding is very intensive, continuous processing can also be achieved, and the material can also be continuously ground and discharged. The components of the sand mill are very simple, mainly composed of the body, the grinding cylinder, the sand grinding disc (lever), the grinding medium, the motor, and the feeding pump. The production efficiency of the sand mill can be self-adjusted, not only by feeding The speed of the pump is controlled, and the fineness of the material can be controlled by different grinding media. Generally speaking, there are many kinds of grinding media for sand mills, the most common ones are zirconia beads, glass beads, zirconium silicate beads, etc.
There are many advantages of vertical sand mills. The sand mill adopts vertical or rod-pin type. The design of the whole machine adopts a closed cavity design. Compared with the traditional horizontal sand mill in the past, this design method reduces Several shortcomings of the old-fashioned sand mill, such as uneven distribution of grinding media and poor particle size distribution after grinding, which are perfectly overcome. When grinding materials, the grinding discs must be installed on the stirring shaft in a certain order, so as to cause damage to the machine or insufficient grinding fineness.
Vertical sand mill with excellent cooling performance
- The material is pre-cooled in the eddy current guiding gap;
- In the outer grinding chamber, also has a very effective cooling function for the stator and rotor.
- The material can be effectively cooled when the material is turned back at the bottom of the stator.
- When the material flows through the inner grinding chamber, the stator and rotor are effectively cooled.
- When the material on the inner surface of the rotor is in constant eddy current motion, it can bring strong cooling to the inner grinding chamber.
The advantages of a vertical sand mill for application fields
Why are vertical sand mills recognized from various fields? This mainly depends on its own advantages, such as paint, varnish, agrochemical, ink, chemical, paper, and other fields, but also has certain advantages.
- Can make car paint, high solids, and water-based products more lustrous;
- It can make heavy coatings have higher resistance;
- High photosensitive pigments can be achieved at the nanoscale;
- Can produce higher quality dyeing slurry;
- It can make high-quality packaging and silver foil ink more glossy and transparent;
- It can make the special inkjet products more high-quality.
According to different material types, it is also necessary to choose different types of sand mills. For example, there are many kinds of inks, and to produce different kinds of inks, it is generally necessary to choose a suitable model.
