Overview
SK-120 sand mill is a factory-sold dispersion equipment, widely used in Coating, dyestuff, inks, pesticides, magnetic tape, paper, leather, chemical and other industries. The equipment has the advantages of simple structure, stable start, high continuous production efficiency, convenient color change, easy cleaning and simple operation.
Features
1. Simple structure and stable starting
2. High continuous production efficiency
3. Easy to change colors and clean
4. Easy to operate
5. Fineness requirements can be adjusted according to the grinding medium
Principle
The working principle of this machine is that the liquid-solid mixture has been pre-dispersed and wetting treated. The material is sent into the grinding cylinder by the feed valve at the bottom of the grinding cylinder and the grinding medium in the grinding cylinder is sent together by the high-speed swirl/spin disperser Stir, so that the solid particles in the material and the grinding medium produce a strong shear impact, so as to achieve the purpose of grinding fine particles and dispersing polymers. The liquid-solid suspension after grinding dispersion flows out through the sieve at the top of the grinding cylinder.
Applications
Coatings, dyestuffs, inks, pesticides, tape, paper, leather, chemicals
Steps
1. Prepare well before the test run
2. Check whether the installation of each component is firm
3. The swirling/spinning direction of each machine should run in the direction indicated by the arrow (the test direction should be clicked)
4. Check whether the chilled down water is smooth
5. The triangle belt is adjusted correctly and suitable for restarting. After 50 hours of work, adjust it again.
6. Add the grinding medium from the top of the cylinder
7. Start the feed pump first, and start the main engine after the input material is discharged on the top screen.
8. When starting after parking for a long time, in case of "stuck" tight phenomenon, the application of hand in the spindle pulley "disc" auxiliary, input a small amount of solvent to make the material dissolve and loosen before starting
9. If the parking time is long, the materials dried by the sieve should be cleaned up
10. Clean the disperser and rotate it only slightly and intermittently
11. When using the new grinding medium, it should be sieved to remove foreign matter such as impurities and fragments
Notice
• Check the installation firmness of each component before the test run
• The swirl/spin direction must be indicated by the arrow, click the test direction
Make sure the water is chilled down
• The triangular belt needs to be adjusted properly, and then adjusted after 50 hours of work
• Start sequence: start the feed pump first, and start the main engine after the top screen is discharged
• When starting after parking for a long time, in case of "stuck" tight phenomenon, it cannot be forcibly started, and the hand "turning" should be supplemented and the solvent should be input.
• Long parking time to clean sieve dry materials
• Only slight, intermittent rotation when cleaning the disperser to avoid abrasion crushing caused by rapid operation
• The new grinding medium should be screened to remove foreign matter before use
