Don't Forget The Last Point About The Purchase Skills Of Sand Mills!
Nov 15, 2021
The sand mill is currently the most widely adaptable, advanced and efficient grinding equipment. With high-performance cooling system and automatic control system, it can realize continuous processing and continuous discharging of materials, which greatly improves production efficiency. At present, sand mills are widely used in chemical industries such as coatings, paints, inks, dyes, and pesticides. Then it is very important to choose the right sand mill. The following is a summary of the seven purchasing skills, I hope it will be helpful to everyone.
1. The material of the grinding barrel: In the sand mill industry, most of the outer barrel of the grinding barrel is made of stainless steel. There are also many types of stainless steel materials, which need to be carefully confirmed; the inner liner of the grinding barrel High wear resistance materials are mostly used, such as ceramics, polymers, alloy mesh, stainless steel, etc., and you can choose the right one according to actual production needs.
2. The form of the grinding bucket rotor: In terms of the structure of the sand mill, the grinding bucket rotor on the market is mainly divided into two types, one is a combination of disc and rod, the other is a pure rod and pin type, and the latter The grinding fineness is higher than that of the former, and the production efficiency of the former is higher than that of the latter; therefore, you need to choose according to actual production requirements.
3. The separation effect of grinding media and materials: The separation device of the sand mill must be ensured that it will not be blocked and has a long life, otherwise it will affect the production efficiency.
4. Mechanical seal and cooling effect: When selecting a sand mill, it depends on whether the mechanical seal leaks. If the seal is not good, it will directly cause the machine to leak when grinding materials, causing unnecessary economic losses. Secondly, if the mechanical seal cooling is not circulated, it will directly affect the service life of the equipment, so pay attention to these two aspects when purchasing.
5. Operational simplicity: Whether the sand mill is easy to operate depends on whether the main control system of the machine is centralized or not. If the control system layout is scientific and reasonable, the operation will be easier.
6. Easy to replace parts: When choosing a sand mill, pay attention to whether it is convenient to change the color, clean and replace the zirconium beads.
7. Safety protection function: It can be analyzed from whether the sand mill has a temperature gauge and a pressure gauge, as well as the interlock between the feed pump, and the sealing liquid pump and the host, and whether the motor has an explosion-proof function.
