CONCRETE PRODUCTS & CAST STONE108 CPI %u2013 Concrete Plant International %u2013 1 | 2026 www.cpi-worldwide.commodes are available: conventional palletising or direct loading onto the grinding machine conveyor in tracking mode.The palletising system relies on several reused materials, including the shipping pallet buffer, the full pallet pusher, the pallet conveyor and the light safety barriers. The concrete block grinding machine supplied by Quadra is well known for its machine tool-inspired design, which makes maintenance easier and provides excellent accessibility. Dust and pollution control is optimised thanks to a high-performance extraction system. The blocks, with a height of between 170 and 300 mm, are machined on the upper face with a height tolerance of %u00b10.3 mm. The drying time before grinding, which is between 24 and 48 hours, determines the machining speed and the quality of the result.The grinding equipment comprises four independent modules: a diamond roller roughing module, two diamond tooth roughing modules and a finishing module. Each module is individually adjustable on slides to ensure rigidity and precision. A motorised conveyor with variable speed drives the blocks without damaging their edges. The cutting depths are adjustable with an accuracy of one hundredth of a millimetre, thanks to servo motor reducers and ball screws. The machining rollers are driven by motors positioned on one side of the machine for simplified maintenance.The upper surface of the blocks is cleaned using a combination of brushing, blowing and suction. The brush is mounted on an electrically adjustable rocker arm, while the blowing ramp has adjustable nozzles powered by compressed air. An upper cover allows dust to be extracted via a centralised suction system.The robot operates in two modes: conventional palletising or direct loading onto the grinding machine conveyor in tracking mode.Machining of blocks on the upper face with a height tolerance of %u00b10.3 mm.
