The recycling unit is the technology for the continuously controlled process of recycling and drying screened abrasive during which the intensity of batching of the abrasive is regulated according to the temperature in the drying oven. The control system continuously measures the current temperature and on the basis of this data it decides on switching the heating elements on or off or turning the batching process on or off; this control is based on the temperature hysteresis and on changing the intensity of batching of abrasive, which is subject to switching the heating elements or turning the batching process on or off.
A method for recycling abrasive material used for high pressure waterjet cutting from cutting sludge is characterised by conveying the cutting sludge to a vibrating separator separating smaller and larger particles from the abrasive, then depositing of the abrasive into a water-permeable container (17);
A drying unit for a recycled material for recycling abrasive material used for high pressure waterjet cutting from cutting sludge is characterised in that it consists of a storage tank (1) for a wet abrasive (A) with a screw conveyor (3) connecting into a drying oven (4), which contains at least one heating element (6), at least one temperature sensor (5), and in that it is provided with an inlet for bringing clean air (E) from a drying blower (7), an outlet (B) for a dry recycled materials (C), which is connected to a vibrating separator (8), and a space under a mesh screen of the vibrating separator (8) is connected to a container or a bulk bag (9) for the dry screened recycled abrasive (C).
A recycling unit for recycling abrasive material used for high pressure waterjet cutting from cutting sludge is characterised in that it consists of a flat vibrating separator (16) with a mesh screen with 3-4 mm openings and a mesh screen with 0.5-1 mm openings and an inlet for cutting sludge, and a space above the mesh screen with 0.5-1 mm openings of the flat vibrating separator (16) is connected to a container or a bulk bag (17) for a wet screened recycled abrasive (A) and a space under the mesh screen with 0.5-1 mm openings of the flat vibrating separator (16) is used for discharging water (I) with fine waste.
