CONAIR MARTIN PLASTIC GRANULATOR #LP-1016 Made by Conair Martin Model# LP-1016 This is a Conair Martin Plastic Granulator in good condition LP model granulators are designed for robot or conveyor fed sprues, runners, and light duty parts. The LP granulator should not be batch fed. Primarily designed for beside-the-press applications, the LP granulators have a low infeed height for closed-loop robotgranulator systems. The low rotor speed provides better regrind, less noise, reduced flyback, and less wear with abrasive material. Specifications Maximum throughput 200 lbs/hr Cutting Chamber 10 x 16 Rotor Speed 140 RPM Rotor Type Standard Helical Rotor Segments 9 InFeed 15 x 18 Screen holes 316 Blower size 2 Horsepower 5 Voltage 460 3ph 48 x 35 x 72 Overall Dimensions Weight 1400

Wow!!! Do you have videos or photos of that ?

Hello fella, I do have a granulator of 14*20, it works good but I need more production, like 400kg or more every hour

In playing around with ours a lot of the time is spent with the plastic bouncing around if it's not fed in consistently. IE: dumping a pile in at a time isn't as good as flattening and then slowly feeding in a few pieces at a time. If my machine is 10" x 16" / 5HP and rated for 90kg/hour then by very basic math (napkin calculation!) you'd need ~22HP with a throat area of 25.4cm x 179cm assuming everything scales linearly. You can throw as much horsepower as you want at it but unless you have the blade area to take advantage of the extra power it won't go any faster

We have an industrial surplus equipment broker very closeby, so we just bought our machine used from them. They have lots of machines now but unfortunately shipping/testing them probably isn't worth it for someone farther away: https://hgrinc.com/?all=1&last_chance&view=grid&aisle=&from=&to=&markdowns=0&newarrivals=0&sort=&kw=granulator&per_page=24&min_price=&max_price=&item_location=watertown&promos=&brand&pn=1 They'll keep lowering the price until they reach scrap metal value

Nice!!! Thanks bro, I’ll take a look

That's 3 phase?

yeah that's 3 phase, doesn't have reversing built in though. I haven't put a VFD or anything on it, it'll stall but only if you put a lot of stuff in at the same time (edited)

It's probably easier to just get an oversized VFD and have that generate 3 phase for you, they'll typically run on single phase as long as they're ~30%+ larger than the application (IE: need a 3HP drive minimum for a 2HP load) and they don't have phase protection (some won't run unless they detect all 3 incoming phases). Something like this would work: https://www.vevor.com/variable-frequency-drives-c_10745/vevor-7-5kw-variable-frequency-drive-vfd-220v-10hp-inverter-converter-rs-485-vsd-p_010647304720

make sure you program the VFD for 60hz output otherwise if it's running at 400hz it won't work

Perfect! Waterppk, you're like a translator in the foreign Land of Electronics for me! Still learning to speak, and very much appreciative. Should I expect a clear reduction in power as well? (edited)

VFD's do some magic internally - all of the incoming power (single phase or 3 phase) is rectified into DC power in some large capacitors. So the AC incoming power turns into DC power, this DC power is then chopped to create an output 3 phase wave form with variable frequency to drive the motor at variable speed. There's certainly loss of power at low frequencies but if you're running at full frequency the motor is at full power. Because you only have 2 wires instead of 3 wires carrying incoming power you need to oversize the VFD so the capacitors are big enough to handle less incoming power (ripple kills capacitors, you get high ripple if you're demanding too much power through them)
