Answer: Cow manure has high moisture content and a sticky, wet texture; standard crushers often suffer from clogging, material clumping, and screen blinding, making this a common challenge in organic fertilizer production. Therefore, the preferred choice is a "half-wet material crusher"—equipment specifically designed to handle cow manure—which is suitable for crushing the manure both before and after fermentation.
First, avoid standard hammer mills entirely. Unfermented cow manure typically has a moisture content exceeding 60%; standard equipment cannot handle such wet material and is prone to jamming, stalling, and uneven output. These issues not only reduce production efficiency but also increase equipment failure rates and maintenance costs. In contrast, half-wet material crushers feature a screenless design that completely eliminates clogging issues, allowing even highly moist and sticky cow manure to be crushed with ease.
Second, select a model based on your production scale. For small home workshops or startup organic fertilizer plants, a compact unit with an hourly output of 1–3 tons is sufficient; these offer excellent cost-effectiveness, a small footprint, and low energy consumption. For large-scale facilities, it is advisable to choose a larger model with an hourly output of 5–10 tons; these are compatible with continuous production lines and can be paired with compost turners and granulators for higher efficiency.
Finally, pay attention to equipment details. Prioritize models equipped with dual-blade rotors and wear-resistant alloy cutter heads. These ensure uniform particle size and break the manure down into fine fragments, facilitating thorough fermentation and maturation to improve the quality of the organic fertilizer. Additionally, look for built-in automatic cleaning functions to effectively prevent material adhesion; this simplifies daily maintenance and ensures greater stability during long-term operation.
