Description

Technical field [0001] The invention relates to the technical field of feed processing, in particular to a feed grinder with an improved screening structure. Background technique [0002] Feed is the general term for the food of animals raised by all people. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, additives, whey powder, oil, meat and bone meal, grains, and sweet sorghum. In 2007, China's feed industry is facing good development opportunities. Feed accounts for more than 70% of the production cost of animal husbandry, and the contribution rate of science and technology to animal husbandry exceeds 40%. The development of the livestock and poultry industry in 2007 was good, and the overall situation of livestock and poultry production and sales would be better than that i...
