In fertilizer production, the selection of crushers needs to accurately match the characteristics of raw materials. Special equipment such as chain crushers and semi-wet material crushers have their own strengths. Only by choosing the right one can the pre-treatment process be more effective.
Chain crushers are ideal for handling blocky raw materials with higher hardness. Its built-in high-strength chain rotates at high speed, which can easily crush hard materials such as ore and phosphogypsum. The wear-resistant design of the fuselage reduces dust leakage and is suitable for the coarse crushing of compound fertilizer production lines.
Facing wet materials with a moisture content of 30%-60%, half-wet material crushers are a powerful tool. The unique dual-axis differential stirring structure can avoid blockage of sticky materials such as chicken manure and sludge. The material stirring is completed synchronously during the crushing process, and the uniformity of the discharge is more than 90%. It can be connected to the fermentation process without additional drying. It is the core equipment for organic fertilizer plants to handle wet manure.
Small and medium-sized fertilizer plants pursue cost-effectiveness, and cage crushers have significant advantages. The crushing is achieved by high-speed collision of the inner and outer double-layer cage bars. It is suitable for medium-hard raw materials such as corn cobs and bean cakes. The finished product particle size is 2-5 mm and impurities. The equipment investment cost is 20% lower than that of similar models.
For fiber raw materials, the straw crusher performs outstandingly. Its blade and kneading mechanism are designed in combination, which can crush long-fiber materials such as corn stalks and straw into 1-3 cm small segments. The fiber cutting rate exceeds 95%, avoiding entanglement and blockage, providing high-quality carbon source raw materials for organic fertilizer fermentation, especially suitable for production scenarios with crop straw as the main material.
For processing high-purity urea raw materials, the single axis urea crusher is a special choice. The low-speed grinding structure is combined with the cooling system to avoid the friction and heating of urea during crushing. The fineness of the discharge can reach more than 80 meshes and the purity is not affected. It can accurately control the uniformity of the finished product particle size. It is an indispensable equipment in the production of high-nitrogen compound fertilizers.
The selection of the crusher must be closely related to the characteristics of the raw materials. Only by precise matching can each device become an efficient engine of the production line and lay a solid foundation for the production of high-quality fertilizers.
