Background

The biomass energy is energy provided by living plants in nature, and the plants store solar energy by taking the biomass as a medium, and belong to renewable energy sources. The energy stored by biomass is calculated to be 2 times greater than the total energy consumption in the world at present. The earliest source of energy used historically by humans is biomass energy. Before the second half of the 19 th century, the energy used by human beings is mainly firewood. The current ways of using biomass energy more efficiently are: and preparing the methane. Mainly uses urban and rural organic garbage, straws, water and human and animal excreta to generate combustible gas methane for life and production through anaerobic digestion. The biomass is used for preparing alcohol. In the current world energy structure, biomass energy accounts for a very small proportion. Wherein the straw is often smashed as the raw materials of burning and the fodder of domestic animal, but at present when smashing the straw, often because the straw is difficult to avoid when collecting can mix including a large amount of small stones to easily cause permanent damage to the rubbing crusher when smashing.
