1. Airtightness of the cooling system: The water outlet is closed during the airtight test of the cooling system, and the compressed air of 0.3 MPa is passed through the water inlet. After cutting off the gas source for 2 minutes, it should meet the air tightness requirements.
2. Rotating tooth running flexibility: The turning tooth running flexibility is checked with a special wrench.
3. Flexibility of the gap adjustment mechanism: The flexibility of the gap adjustment mechanism is manually checked.
4. Dial zero indication: The zero mark of the dial indicates the accuracy check: When the rotation and the fixed tooth gap are reduced, the special tooth wrench is used to rotate the rotating tooth. When the friction sound of the fixed tooth is heard, it is zero.
5. Operation test: The operation test is carried out from the feed hopper and the clean water with anti-rust liquid.
6. Particle size of crushed material: The test method for particle size of crushed material should be carried out as required.
7. Emulsified material particle size: The test method for emulsified material particle size should be carried out as required.
8. Appearance quality: Appearance quality should be checked by visual inspection and should meet the requirements.
