Machinery Function Features
For fast and perfect polishing of marble slabs up to a max width of 200 cm.
Basement group:
The basement is made up of one rubber conveyor belt with anti slip tooth surface slides manufactured in order to obtain the maximum stability, precision of work and longer life.
This group is formed by:
- Basement of welded steel.
- Milled steel plates welded on the basement where the abrasive stones are acting.
- Driving roller and tensioning belt roller, with a special device that permits to adjust the conveyor belt stretch.
- Splash and lateral guards in order to avoid coming out of water.
- HP 3 motor for speed variator of the conveyor belts from 0 ÷ 2 mts. per minute.
Bridge:
Made up of electrowelded steel with high mechanical resistance with n°10 spindles prearranged to hold grinding polishing plate prearranged to hold the abrasive stones. The bridge is sliding on rectified and protected steel guides with adjustable speed by means of hydraulic motor controlled by a hydraulic central unit of 5,5 HP.
Spindles holding grinding/Polishing plates:
Seasoned cast-iron made, duly ribbed, made up of:
- Flanged motor HP 10.
- Belt transmission pulley with tensioning device of the same.
- Chromium plated rod holding spindle shaft, protected by rubber bellows.
- Spindle shaft rectified in side of ball bearings and grooved for perfect coupling with pulley.
The vertical lift and working pressure of the spindles is obtained by a hydraulic central unit of 4 HP.
Each spindle is controlled by the following equipments:
- Manometer for pressure reading on the abrasive stone.
- Push-button control for up and down movements of the working plate.
- Hand-grip for pressure adjustment.
- Cylinder and piston for rapid lifting of the rod holding the spindle, coming down and pressure adjustment on the abrasive stone independent from the consumption of the same.
- Connecting tubes and other pipe fittings.
Electric plant:
Electric plant type "Telemecanique" controls and protects the machine motors. Made up of:
- Water proof metallic locker, containing fuses, thermal relay, remote control switches and remaining electrical components for the automatic and stop safety equipment for each single motor.
- Control board push button and low tension, with working lamps for each single spindle.
- Amperometers for spindle motor.
- Connecting cable collector for single motor, with machine terminal board.
- Terminal board for connection of the machine to the electrical board.
Slabspresence reader device:
The slabs presence reader device, our type "STEPMATIC" is made up of n° 3 sensors located on the front part of the machine, provide to check the slabs presence thanks to electronic device which controls the plate up and down movements according with the belt speed and the presence of the slab. This system allows to anticipate or postpone, directly from the control board the lifting lowering of the plate in order to follow the speed of the belt and to modify the lateral position of the sensors according to an eventual defect of the block.
Standard accessories:
- n°10 Plates Ø 450 mm. to hold the abrasive stones
- Foundation bolts for the basement.
- Set of service keys.
- Lubrication syringe.
- Detailed instruction book for the machine erection, maintenance and lubrication.
Technical data:
- n°10 Motors of 10 HP for spindles holding abrasive stones.
- n° 1 Motor of 3 HP for belt working speed adjustment.
- n° 1 Motor of 4 HP for hydraulic unit of raise and descend of spindles.
- n° 1 Motor of 5,5 HP for bridge holding spindle traverse movement.
Total power installed : HP 112,5 = 83 Kw.
Real consumption : 65% of the installed power that is about 54 Kw/hour.
Water consumption : About 125 litres per minute with 2 atm pressure.
Weights : Net 11,30 tons. With sea package 12,70 tons. Volume 100 cub. mts.
