How to calculate pressing ration of biomass pellet mill ?
The ratio of pellet mill ring mold refers to the effective working length of the ring mold and die hole diameter ratio. According to the raw material formula and product requirements to select the ring pressing ratio.
Well, according to Kingwood's previous experience , let's give a few example. Eucalyptus compression ratio is 1: 3.7 ~ 1: 4, mahogany compression ratio is 1: 4 ~ 1: 4.5, hardwood compression ratio is 1: 4.5, pine compression ratio is 1: 5 ~ 1: 6 , The compression ratio of poplar is 1: 6 ~ 1: 7, bamboo is 1: 4, the compression ratio of corn stalks is 1: 6 ~ 1:8,(It is regular ratio but the real is on the basis of raw material ,moisture .
Compression ratio of different raw materials are different, the harder the raw material compression ratio is smaller, the more bulky raw materials are ,thr larger compression ratio, which means that the more fluffy raw materials easier to shape, the more fluffy raw materials containing more fiber,fiber-containing materials Easy to shape, then let's talk about poplar compression ratio of 1: 6, 1 and 6, respectively, which represents what?Pellets coming directly 6mm, 8mm, 10mm, the 1 represents the diameter of each hole hole, if the ring hole diameter is 8mm, then the 1 represents the 8 , And 6 represents the effective aperture, the effective aperture is equal to the diameter of the hole multiplied by the effective aperture length, which is 6 * 8 = 48, that is, 8: 48.8: 48 reduced to 1: 6,1: 6 Is the compression ratio of poplar, is the conversion, wood pellet machine discharge depends on the ring mold compression ratio, but if the customer for your production of wood pellet molding rate is not very high, then you can properly reduce the compression ratio , So that both to incre
