Introduction of 800-1000kg/h Straw Pellet Production Line

In most situations, straw is considered as a kind of crop waste, such as corn straw, rice straw, wheat straw and cotton straw. These straws are trouble problem for farmers, so it would be a pleasure to get rid of these wastes. Some farmers choose to burn them in the land in the past, however right now people are more likely to make the best use of them–using straw to make pellets. Straw pellets are one renewable fuel and featured by low pollution, emission-reduction and economical.

SKLN1.5 Counter Flow Pellet Cooler

Pellets has high temperature and moisture content after discharged from pellet mill, so counter flow pellet cooler is adopted to reduce temperature and moisture content. After cooling, moisture content of pellets can be reduced to 12%-13%, temperature can be reduced to about 3-5℃ above ambient temperature. This machine adopts the counter flow cooling principle, the cooling time is increased. Cooling effect of this machine is remarkable.
