Description

PELLET MACHINE mod. N-PLUS-A – As per E.C. rules (output 1000/1500 kg/ora)

By Pellet machines N-PLUS you can save money, obtaining a low production cost of pellets, because these machines were developped in order to generate a low ratio between installed electric kW and pellet production per hour. Such innovation comes from the carried out planning and development that have led to production of machines of new generation as to the technologies deriving from the feed sector with the purpose to make customers obtain economical advantages (energetic saving and low maintenance cost and times) and high quality in pellet production. The produced pellet will be marketable either on home market or on industrial one, because no type of additive or adhesives is used, natural or not.



Drawplate internal diam. mm. 580

Presser roll diam. mm. 245

Pellet diam. mm. 6-8

Overall dimensions mm. 2400x2500x2400

Technical card of productive efficiency

Installed active power 110 kW

Electric feed V. 400 +/- 10% Hz 50/60

OUTPUT PER HOUR

– essences of tender wood (fir, poplar, pine, olive) 1000/1500 kg/h

– essences of hardwood (beech, bay oak, olive) 900/1200 kg/h

– ratio consumed electric kW / produced kgs of pellets = 1/18



Information about general typologies of theinput materials in the pellet machine:



♦ Morphology: sawdust or material with granulometry not less than 0.5 mm. and not more than 1.5 mm.

♦ Humidity ratio: between 8% and 14% at the most

♦ Features: all types of wood or other materials, free from ferrous material



Innovative features of the N-PLUS pellet machine (as to the pellet machines developped by the fodder sector):

– patent: “Frame for pellet machines”

– patent: “Feeding system for pellet machines”

– positioning setup of external pressing rolls, with the possibility to change during the working cycle without stopping pellet machine

– no use of additives or bonding agents, even of animal origin

– high energetic class motors IE2 (ENERGETIC SAVING)

– inverter for the control of the main motor (optional)
– sawdust loading in the compression drawplate through an only central screw

– presser rolls: not overhang ones, but hooked to the structure of the pellet machine

– ring die of easy replacement and low consumption of tools

– hydraulic gearcase for lubrication of presser rolls and chuck
– adding by vegetal oil for working cycle start and end (in order to avoid hardening of the remaining material in the compression circuit when the machine doesn’t work)

– reduced encumbrance

– reduced cleaning and maintenance times thanks to the direct opening of teh pelletizing zone and the quick tool replacement



General features

– Pellet machine with mechanical and electric working system

– Control and management by means of PLC Siemens and Touch Screen

– Manual adjustment of presser rolls (that allow the rotation of the compression drawplate)

– Material loading system through an inox steel tank and a batching screw adjusted by an inverter, that is controlled proportionately to the working couple of the compression screw

– Compression holes of the drawplate = mm. 14-50 long, variable according to the material that must be worked (sawdust or other vegetal/agricultural wastes)

– Front pellet evacuation

– Min./max. level indicator on the loading tank of materials

– Manual motor greasing controlled by PLC

– Automatic grease lubrication of presser roll and chuck

– Safety electric lock of the opening door of the drawplate and presser rolls

– Protection carter of motor belts

– Lifting sockets for truck on theground

– Prearrangement for connection of dust and steam suction intakes

– Use and maintenance handbook and E.C. marking



Pellet machines N-PLUS-series are equipped with:
– Electric board with PLC Siemens S7200 and modem for remote connection
– Batching screw controlled by inverter

– External adjustment of pressing rolls and doors for quick cleaning

– Atomizer for addition of moisture to sawdust hopper

– Mechanical level sensor

– Oil pump for cycle end and automatic grease lubrication

– Presetting for suction hoses

Therefore for each supply it’s required to send a sample of material to be reduced into pellet in order to determine the suitable tools for customers.
