In the email, the client said concisely, “…I am looking for equipment to pelletize my organic raw materials. Please tell me the KW and hourly capacity of it.” To be honest, we can only design an ideal fertilizer production line when we know the details of each client’s plant project. Therefore, we phoned him to ask more about the organic fertilizer production line he wanted. After the talk, we found out that the buyer had a commercial cattle farm with at least 10,000 cows, and he needed to set up an organic granulation plant to make his cattle manure into organic fertilizer granules for sale. According to the annual capacity of cow dung and the layout of the plant, we drew the design of an 8 t/h rotary drum granulation line for the customer.
