small pellet machine/rice husk pellet machine/dog food pellet making machine
Raw material application
1. Crop stalks (including cornstalks cotton stalks ),grain shell(rice husk ) ,peanut shell and stalks, cotton stalks, sawdust,branch,bark ,bamboo powder, furfural residue(could be mixed used), Wood scraps ,Forest harvesting slash, household refuse,scraps produced by paper making factory,all of these could be smashed and briquetting .
2. Notice : The moisture of raw material have to be kept at around 15%, and the length must within 10mm.
Biomass briquette Production Flow:
Raw material Smash → Drying(moisture 15%) → Enter molding machine→Curing
and shaping under high temperature and high pressure → Product cooling →
Packaging and sealing → Delivery
Cost of production
Cost of production/T=Electric charge of 40kw/T+labor cost(2workers)/T + Mechanical loss cost ( 0.16-0.83USD )/T
Principle of forming
The machine get reciprocating motion by pulley driven by eccentric wheel, and then the feeder machine will start to feeding. Then the raw material go through distributor to get into the feeding box on the briquetting machine, and the next step is from feeding box to molding machine by the appending machine from two sides . Under the pressure caused by punch and molding die ,the raw material become heating up and softened ,and the volume become smaller. Then the raw material get solid and being extruded by molding die with reducing taper due to repeated impact .
Pellet shaping process is effected by pressure and temperature ,so the operation principle is punch principle ,the machine carry punch 280 times /min when it works normally. The pressure will up to 300T and the temperature is 150200°C, so the equipment could be used widely for so many kinds of raw material and enjoying a excellent forming density. In addition ,all parts of the equipment lubricated forced by the Oil pump
lubrication system to ensure the equipment enjoy a longer service time.
