For our standard wood chippers, among the most popular serious, 216 model can produce 5t per hour, 218 model can produce 8t per hour, 1250 model can produce 10t per hour.

But sometimes, client wants a 1.5t or 2t per hour line, but we designed the line with chipper 218 or even 1250, why?

This may be the question for some of the clients. As the raw materials for biomass producing are different. Very different. Some of them don’t need to use wood chipper, like straw, rice husk. And some client will make pellets from logs. The log diameter will influence the choice of the chipper. For example the feeding port of the wood chipper 216 model is 230*540mm – the max diameter for it is 200mm. If the log is bigger than 200mm, it can’t go through the feeding port.

Another question is: “As you say 216’s feeding port allowed input wood with 20cm diameter, my wood is 30cm, the 218’s feeding port is 300*680, it’s means it can work up to 300mm, why suggest us to take 1250 model?” That’s a good question. 218 can process wood logs up to 30cm, but if all the woods are between 25-30cm, it’s a heavy work for 218. It can work, but affects service life.

Then the third question comes – As the feeding port size decide log size it can take, while we don’t need big capacity, can we order a small capacity model with bigger feeding port? – The answer is no. It’s a pity, but the motor will be not powerful enough. Chipping big wood need strength, the feeding port should be bigger, and the motor should be bigger too.
