2 New RSP 15 Series The new low speed RSP 15 Series is the first step of a revision that is to affect the whole range of Piovan granulators. The target is the repositioning of Piovan granulators on the market. Piovan RSP 15 Series Granulators are designed for the immediate recovery of sprues and waste pieces beside the injection moulding machine. The range is formed by 4 models: RSP 1515, RSP 1523, RSP 1530 and RSP Mktg Dept (l&g) RSP 15-eng re.01 modification reserved

3 RSP 15 Series Design Input naked version (open lower part) New standard hopper h 1200 mm (ideal for manual, robot and conveyor-belt feeding) New more compact hopper h 1000 mm (for shorter conveyor belts) Floor-stand frame version (to increase the volume of regrind available) Easy cleaning operations New safety devices Reduction of machine dimensions (direct extraction version) 3 Mktg Dept (l&g) RSP 15-eng re.01 modification reserved

4 RSP 15 Comparison with the previous RS 15 Series models. The following features are unvaried: range: 15/15-15/23-15/30-15/38 the granulation chamber is unvaried; now it is more compact Rotor with 2 or 3 rows of blades with lateral discs (closed type) Multiple staggered cutting blades Blades with scissor-like cutting action Access to the granulation chamber by means of hand-operated hooks Stainless steel grid Basic frame with castors Electric box integrated on the machine structure Regrind extraction versions (direct, inclined screw, cyclone and blower) The independent flywheel has been changed with a flywheel pulley (option) 4 Mktg Dept (l&g) RSP 15-eng re.01 modification reserved

5 RSP 15 In occasion of the re-design of the granulators we have improved the following aspects: Smooth fall of material into the hopper Cleaning operation time Back flow of regrind material Safety devices Hot temperature on the granulation chamber Problems of belt brunings Grid centring operation on the grid support 5 Mktg Dept (l&g) RSP 15-eng re.01 modification reserved

7 RSP 15 Structure Compact and solid baseframe: on 4 castors, 2 of which are pivoting and with brake. The base-frame is prearranged as standard for a floor-stand application. 7 Mktg Dept (l&g) RSP 15-eng re.01 modification reserved

RSP 15 Granulation Chamber Sturdy: Granulation chamber walls and

according to the original Piovan design.

8 RSP 15 Granulation Chamber Sturdy: Granulation chamber walls and rotor are thick and sturdy, made entirely in-house at CNC centres according to the original Piovan design. The sturdiness of the cutting mechanism allows for the recovery also of abrasive materials. In the latter case, the nitrurated chamber option is recommended (version with 3 rows of blades). 8 Mktg Dept (l&g) RSP 15-eng re.01 modification reserved

13 RSP 15 Feature of the Rotor The granulation-dust collecting side pockets are now placed on the side of the granulation chamber. On the sides of the granulation chamber, there are two connections for compressed air, so that it is possible to perfectly clean also the lateral discs with no risk of contamination. 13 Mktg Dept (l&g) RSP 15-eng re.01 modification reserved

14 RSP 15 Feature of the Rotor The rotor has been specifically engineered to prevent material from getting stuck in the spaces in between blades/blade-holders. As a consequence, it is possible to perfectly clean the rotor group especially when changing material. 14 Mktg Dept (l&g) RSP 15-eng re.01 modification reserved

The grid is reversible and in stainless steel. According to the size required, different grids are available (holes diam 4-5-6-8 mm.

15 RSP 15 Blades and grids Mobile and fixed blades are the same of the previous RS series. Mobile blades are disposable, they can be changed quickly and need no adjustment. Fixed blades can be re-sharpened with the possibility to adjust them. The grid is reversible and in stainless steel. According to the size required, different grids are available (holes diam mm.) For the recovery of thin sprues, a special grid version with 6 mm diameter holes is available. The grid support has been reinforced and the centring of the grid now is simple. 15 Mktg Dept (l&g) RSP 15-eng re.01 modification reserved

19 RSP 15 Safety devices The safety devices have been changed, abandoning the button solution in favour of a double safety device with hand wheel that allows the rotor to stop before the operator can access the granulation chamber. The granulator operates only when all the safety devices are on. The operator must manually un-block a safety device in order to access the granulation chamber and the grid, and another safety device to open the hopper. The time needed to un-block the safety device(s) is calculated so that the moving parts are completely still when the machine is open. 19 Mktg Dept (l&g) RSP 15-eng re.01 modification reserved

RSP 15 Safety devices Active and passive safety: The distance between the feeding inlet and the rotor prevents any risk of contact, even accidental, from the operator.

20 RSP 15 Safety devices Active and passive safety: The distance between the feeding inlet and the rotor prevents any risk of contact, even accidental, from the operator. The design of the hopper internal surfaces contributes to material fall while preventing material back-flow. 20 Mktg Dept (l&g) RSP 15-eng re.01 modification reserved

21 RSP 15 Feeding Hoppers New hopper design: In comparison with the previous Series RS 15, the main innovation of the new RSP 15 range has affected the hopper, redesigned to allow for a smooth fall of material with no risk of back flowt or getting stuck and maximum flexibility. Flexibility: -The standard hopper (h 1200 mm) is suited for manual, robot and conveyor-belt feeding. (For robot application a large inlet feeding device is available) -For shorter conveyor-belts, a 1000 mm high hopper is available. By adding an optional inlet, the h 1000 mm high hopper can be also used with the sprue picker. (*) The material can be fed only from the extraction side. 21 Mktg Dept (l&g) RSP 15-eng re.01 modification reserved

22 Particular attention has been paid to hoppers which have been designed with a geometrical internal inclination surface. This action has allowed: - Ease of feeding; the feeding hopper facilitates the introduction of pieces inside the hopper, also by means of a sprue picker. RSP 15 Feeding Hoppers - The hopper design facilitates the feeding of long sprues, in particular with the standard hopper h 1200 mm (sprues up to mm). Note: now the angle of the internal surface in the hopper h 1000 is 40 ; this favours material fall. - Avoid the back flow of the regrind material from the inlet point of the hopper thanks to a weightless flexible flap, (this solution does not interfere with the regular fall down of the sprues). - Reduce the noise (amplification effect) 22 Mktg Dept (l&g) RSP 15-eng re.01 modification reserved

32 RSP 15 Cleaning operation As for cleaning operations, the new RSP 15 models represent a significant improvement (comparison with the previous Series RS 15). Access to granulation chamber for cleaning or maintenance operations is now easier due to the open sides. To access the granulation chamber and the hopper it is sufficient to un-block some hand-operated hooks, with no need for tools. The rotor has been specifically engineered to prevent material from getting stuck in the spaces in between blades/blade-holders. As a consequence, it is possible to perfectly clean the rotor group especially when changing material. On the sides of the granulation chamber, there are some connections for compressed air, so that it is possible to perfectly clean also the lateral discs with no risk of contamination. For a good cleaning operation the grid support, the grid and the suction box are: easily, quickly and completely removable. 32 Mktg Dept (l&g) RSP 15-eng re.01 modification reserved

33 RSP 15 Noise The noise level is kept within the limits due to the hopper body soundproofing and the particularly silent cutting action. In order to minimise the noise generated while granulating, changes have been carried out in terms of: > sound-proofing of the hoppers > internal geometry of the hoppers These modifications have resulted into no significant variations in terms of noise levels compared to the previous RS Series. The tests we carried out have detected a noise level of about 75 82dB (at any rate, this depends on the kind of material to be granulated). 33 Mktg Dept (l&g) RSP 15-eng re.01 modification reserved
