Our compost crusher is specifically designed for materials that have undergone the fermentation process. For unfermented raw materials, the crusher can still be used directly, provided that the moisture content is between 20-40%. The typical output size from the semi-wet material crusher is about 5-8mm. If a smaller size is required, we recommend using the straw crusher, which includes an internal screen to achieve a finer crush. However, ensure that the moisture content of the materials for the straw crusher does not exceed 15%.
