The compost turner is the “heart” of an organic fertilizer production line. Currently, the mainstream types are trough-type and self-propelled compost turners, each with its own advantages. The choice should be based on the available space, production volume, and budget.

Trough-type compost turners require the construction of fermentation troughs and travel along tracks. They ensure even turning and thorough fermentation, making them suitable for fixed sites and large-scale production. One machine can be used for multiple troughs, offering a high degree of automation and effective control of fermentation temperature and humidity. They are suitable for medium to large-scale organic fertilizer plants. The disadvantage is the need for initial civil engineering investment, and the site cannot be moved.

Self-propelled compost turners rely on tires for movement, eliminating the need for trough construction. They are flexible and suitable for small sites and windrow fermentation. They have low initial investment, are not limited by site constraints, and are suitable for farms and small processing plants. The disadvantage is slightly lower fermentation efficiency and more manual operation.

For small-scale organic fertilizer production lines with limited budgets, self-propelled turners are a good choice; for large-scale production and those seeking high efficiency and stability, trough-type turners are preferable. Both can meet fermentation requirements; the key is matching the machine to the production scale and site conditions.
