How to deal with the problem of sand mill?
Nano Sand Mill
The sand grinding machine, also known as the pearl grinding machine, is used to grind the paint of the pigment with hard wear -resistant beads, glass balls, etc. in a closed cavity.
Application: Paint, Adhesive, Battery, Pharmaceutical industry, Cosmetic
It is mainly used for wet grinding of chemical products. The pigments are scattered and grinded during the process. The sand mill is divided into two types: horizontal sand mill and vertical sand mill. The horizontal sand mill is widely used in the coatings, chemicals, inks and other industries.
When users use the horizontal sand mill, they often encounter the problem of failure of the sand mill, which mainly exists in the phenomenon of too high temperature or other types.
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.
During the production process, the general material temperature should be below 25 ° C. In order to ensure the sand milling effect and maintain high output in order to ensure the sand grinding effect, the temperature of the coat should be lower than 5 ° C, and the material temperature generally controls at no more than 35 ° C.
Common faults and solutions of horizontal sand mills
1. The motor card is killed. The force of the diaphragm pump is too large, squeeze the beads too tightly. Turn the belt plate, adjust the pressure of the filter, and start the motor again;
2. The diaphragm pump does not work. The solenoid valve is damaged and the solenoid valve is replaced. The diaphragm pump valve stalk is dead, and the air tube is pulled out of the air tube to add a small amount of transformer oil to the entrance, inserted into the trachea to increase the pump gently, and then adjust the pressure to the original pressure after the pump work;
3. Water circulation cannot work. The solenoid valve is damaged or stuck, and the replacement;
4. cooling water whitening. Mechanical sealing cavity disassembly and washing, or replacement of mechanical sealing;
5. The bearing position is fever. The heating of the bearing position is generally not greater than 60 degrees, and it is an abnormal phenomenon that exceeds 60 degrees. It mainly lacks damage to butter or bearing. You should add butter or replace it in time;
6. The pressure gauge is too high. The screen is blocked and cleaned. If it cannot be solved, it should be disassembled and cleaned.

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.
Sand Mill: Enhancing the Efficiency of Grinding & Dispersion
Sand mills, also known as bead mills or media mills, are mechanical devices used in the field of grinding and dispersion.
Instructions for use of vertical sand mill
The vertical sand mill is a nano-sand mill whose grinding cylinder adopts a suspended structure, raw materials enter from the bottom and discharge from the top.
How to choose the right vertical sand mill & horizontal 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.

How to choose a sand mill for paint?
Sand mills are mainly used in industrial fields such as paint coatings, cosmetics, food, daily chemicals, dyes, inks, pharmaceuticals, magnetic recording materials, ferrites, photosensitive films, oxide ceramics, and new energy.
Grinding media for sand mills
Sand mill is a kind of high-efficiency grinding equipment, which is mainly used for grinding materials, and the particle size of the final grinding can reach the nanometer level.
