Cattle manure, due to its high fiber content, loose texture, and long decomposition cycle, is prone to resource waste and environmental pollution if treated directly. Compared to other livestock and poultry manure, the core of treating high-fiber cattle manure lies in "fiber breakdown first, followed by composting, and then granulation."

First, pre-treatment and fiber breakdown to reduce subsequent difficulties. Coarse fiber is the core obstacle to treatment. The cattle manure must first be crushed using a high-power fertilizer crusher to reduce the fiber particle size to 3-5 centimeters, while simultaneously screening out stones, weeds, and other impurities. If the moisture content of the cattle manure is too high (exceeding 65%), dry materials such as straw and sawdust can be mixed in to adjust the moisture content to 55%-60%. This balances the carbon-nitrogen ratio (optimizing it to 25:1-30:1) and improves material aeration, paving the way for subsequent fermentation.

Second, enhanced fermentation and composting to degrade coarse fibers. A trough-type compost turner is used for deep turning and mixing. The powerful mixing force of the equipment ensures sufficient ventilation and oxygen supply to the compost pile, maintaining a high temperature of 55-65°C for 25-30 days. The high-temperature environment accelerates microbial activity, efficiently degrading coarse fibers and simultaneously killing pathogens and insect eggs. Specialized composting agents can be added during fermentation to further shorten the composting cycle and improve the degree of decomposition.

Third, shaping and processing to enhance utilization value. The composted cattle manure, with its coarse fibers largely degraded, can be fed into an organic fertilizer granulator(ring die or flat die pelleting machines are preferred, suitable for shaping loose materials) to form high-strength, uniformly sized granular organic fertilizer through extrusion or rolling.

This treatment plan can be implemented by assembling a fertilizer production line with equipment of corresponding specifications based on production capacity requirements. This not only completely solves the problem of treating high-fiber cattle manure but also transforms waste into organic fertilizer rich in organic matter.
