Model:PSM-R-30L
It is a large flow ultra-fine type horizontal bead
mill.The materials to be ground are input into the grinding chamber through the feeding pump (gear pump or diaphragm pump), and together with the grinding beads in the grinding chamber are stirred by the rotating rod-pin type rotor.Under the action of the high-speed rotating agitator, the solid particles and the strong impact and shear are generated between the agitator and the grinding beads, and the material to be ground is quickly scattered and broken to achieve the purpose of grinding.The ground material moves to the discharge port under the action of the pressure in the grinding chamber, and the grinding beads and the material are separated through the static separation screen.The material is finally sent out through the discharge pipe to complete a cycle, and the fineness of the material can meet the requirements after testing. Enter the next process, if you need finer quality, you need to continue pumping into the grinding chamber for grinding again.
Structure

1. Receiving hopper: used to collect the falling materials and grinding beads after pulling out the grinding cylinder;
2. Frame: support and connect the units of the equipment;
3. Sealing liquid tank: for cooling and lubricating the mechanical seal, balancing the pressure of the mechanical seal and grinding chamber;
4. Electric contact pressure gauge: display and control the grinding chamber pressure during feeding;
5. Feeding port: the raw material is pumped into the grinding chamber from this port;
6. Control box: touch screen or button box, control the mill working;
7. Motor: Supply enough rotational power for the grinding system;
8. Grinding cylinder: include the inner raw material grinding chamber and the outer cooling water jacket;
9. Grinding beads filling port: Add grinding media from here;
10. Electric contact thermometer: display and control the discharge temperature;
11. Discharge port: the raw material flows out from here after grinding;
12. Discharge screen system: isolate grinding media and filter out materials
13. Grinding beads discharge port: it can discharge a small amount of grinding media
14. Cylinder pull-out mechanism: easily pull out the cylinder, clean, repair or replace wearing parts.

How to choose a sand mill
1. Understand the needs of users, especially the material characteristics (name, water-based or solvent-based, explosion-proof grade, grinding fineness, output, viscosity, specific gravity, precipitation, grinding difficulties, etc.);
2. Provide selection guidance and design scheme for users to confirm;
3. Confirm the final plan, if necessary, the customer can provide samples (3-5L), and guide the selection through the actual laboratory grinding.4. Quote;
5. Sign a contract and place an order for production;
6. Delivery;
7. On-site guidance for installation and commissioning, and final acceptance of the product. 8. The product enters the after-sales service stage for a period of one year.
Our Advantages
We treat every process of design and production with a scientific and rigorous attitude. The laboratory is equipped with a micro-scale sand mill and a nano-scale sand mill for customers to make raw material grinding tests, which is convenient for customers to select models. At the same time, it is equipped with a wet laser particle size analyzer to measure the grinding effect.
