(A) before the start of preparations double disc grinding 1, check the refiner installation, fastening bolts, all bolts must be tightened; 2, check the lubrication points of lubrication (maintenance section devoted), all lubrication points must be filled with sufficient lubricant (grease); 3, connected seal cooling water. 4, check and adjust the retraction stroke. The device is always forward, retraction stroke of 20mm, with the cover, the gap between the movable block is 6mm, the travel time from the limit switch has been the role. Confirm the cover, mobile Zama 6mm clearance steps: (1) Remove the cover bolts. (2) open the cover. (3) Turn the handwheel to make the move seat moves back and forth. (4) measuring and determining cover the gap between the mobile seat. (5) Write down the value of the pointer corresponding to the ruler, do pay attention this time limit must play the role of the limit switch, forward, retraction motor is in retraction mode, stop turning, unable to retract. (6) Close the cover and tighten the bolts. 5, confirm the hand wheel steering, the face of the handwheel, plastic clock aspect of feed, and vice versa for retraction. 6, confirm and retract motor rotation (A) to enter, retraction motor wiring. (2) Turn the handwheel so that tapered off limit switch connector 5mm, starting forward, retraction motor, jog retract button, check to make sure the hand wheel steering, thus confirming the inlet and retraction motor rotation. 7, confirm the main motor rotation. The device has two grinding mill area, set inside the right grinding, grinding group left on the outside face of the motor shaft, clockwise rotation, a pumping action, counterclockwise rotation, reverse pumping action . Pumping action: production capacity, beating a short time, increase the value of freeness low pressure large mouth out of the slurry. Anti-pumping action: Production capacity is small, beating a long time, freeness increased value, into and out of the mouth small pressure plasma. Pumping action and return to using the pumping action, according to the need to use, it is recommended that if three series. The first pumping action, every two sets anti-pumping action, third pumping action, maintain the pressure increase is not too high.
Double Disc Grinding prototype samples for spectral analysis rough finish, for metallurgy, forging, casting and other coarse and fine specimen surface grinding and polishing. The machine is simple, safe and reliable. Disc with the same diameter on both sides, can be operated simultaneously, the work can also be a single disk. In order to meet environmental requirements, particularly with a vacuum device that uses no dust pollution, protect the health of operators, simple replacement wheel convenient no dust and noise characteristics of the spectrum before polishing the ideal equipment. Technical parameters: 1 disc diameter: Ф400 2, disc: 2 (double disk) 3, the disc speed: fast disk 2850 rev / min; slow disk 1450 / min. 4, grinding speed: fast disk 25-60 m / sec; slow disk 12.6-30 m / s. 5, the motor: Y90S-2-1.5KW, Y90S-4-1.1KW. 6, the fan (centrifugal): φ200 mm impeller, shaft direct drive mode. 7, Control Type: buttons, switches; (disc button control) (blower switch control) 8 Dimensions: Length 1000 × width 500 × height 800 (mm) 9, Weight: 200 kg
