Introduction to the key components of a compound feed processing unit—save this now!

　　The compound feed processing unit primarily consists of a feeding system, a mixing system, a pelletizing system, and drive and lubrication systems. During operation, compound feed powder with a moisture content not exceeding 15% is fed from the hopper into the feed screw; by adjusting the speed of the stepless variable-speed motor, an appropriate material flow rate is achieved. The powdered feed then enters the mixer, where it is agitated by stirring rods and mixed with steam for tempering. If molasses or oil is required, these can also be added via the mixing tank and blended with steam; the oil content should generally not exceed 3%, as higher levels may hinder pellet formation. After tempering, the temperature of the compounded powder can reach 64–85°C, with a moisture content of 14–16%. Subsequently, ferrous impurities present in the powder are removed by an optional iron‑removal device via an inclined chute, after which the powder proceeds to the compression chamber for pelletizing.

　　Feed processing units can be categorized into feed grinding machinery, mixers, pelletizers, coolers, dryers, grading screens, elevators, feed‑mixing units, pelletizing machines, premixers, crushers, blending machines, dispensers, pulse dust‑removal equipment, and screening equipment.

　　Lightweight feed-processing machinery can be categorized into: feed‑processing machine components, feed‑grinding equipment, mixers, pelletizers, and premixers.

　　Heavy-duty feed machinery can be categorized into feed batching units, pelletizing units, premixing units, coolers, dryers, grading screens, elevators, and more.

　　Depending on their intended use, feed-processing machinery includes feed grinders, mixers, pelletizers, and premixers, all of which are used for feed production.

　　Feed machinery classified by application: coolers, dryers, grading screens, elevator cleaning equipment, and more.

　　What are the main components of a compound feed processing unit? Let’s analyze them below.

　　1. Base: It serves to connect and support all components of the crusher, forming a unified structure, with the crushed material discharged from beneath the base.

　　2. Rotor: Composed of the main shaft, hammer‑support plates, pivot pins, hammer blades, bearings, and other components, it is the primary moving part of the crusher. Due to its high rotational speed, a dynamic balancing test must be performed when assembling the rotor without pins or hammers.

　　3. Operating Door: When replacing the screen plate or hammer heads, open the operating door. During operation, the door lock secures the door to ensure it does not open spontaneously while the rotor is spinning.

　　4. Upper housing: The upper section is equipped with a feed inlet, while the lower section is connected to the base. Screening plates are mounted on both sides, forming a crushing chamber together with the rotor, where the material is pulverized.

　　5. Feed Guide Mechanism: Material can enter the crushing chamber from either the left or right side. The guide plate is manually switched to ensure that the feed direction aligns with the rotor’s rotation.

　　6. Screen‑pressing structure: It employs a rigid locking mechanism to ensure the screen plate remains securely mounted within the crusher.

　　7. Screen Beams: The screen beams and the screen‑pressing mechanism secure the screening plates within the pulverizer.

　8. The feed-processing unit employs a dual-rotor design, significantly enhancing operational efficiency.
