三. Special Knowledge of Feeding Modes (New Expanded Chapter)

Q6: How many standard feeding modes are available for ASFROM pressurized kneader mixers? Which models support them?

A6: All ASFROM kneader mixers of 35L and above provide two mainstream feeding solutions: Back Charging and Front & Back Dual Charging. Customers can select the proper type according to production line conditions, dust characteristics of materials and cleaning requirements.

Q7: What is a Back Charging kneader mixer? What are its advantages and disadvantages?

A7: Back Charging means the feeding port is set at the rear of the machine, and materials are fed into the mixing chamber from the back side. Advantages: The machine has excellent overall tightness without dust overflow during feeding, achieving outstanding dust suppression effect. It is suitable for producing dusty materials such as high-filler powder, carbon black, color powder and lightweight foaming powder, keeping the workshop clean. Disadvantages: There is no feeding port on the front side, so daily cleaning of mixing chamber and manual sampling are less convenient than front & back dual charging models.

Q8: What is a Front & Back Dual Charging kneader mixer? What are its advantages and disadvantages?

A8: The machine is equipped with both front and rear feeding channels, enabling flexible switching between two feeding modes. Advantages: The front feeding area has spacious operating space for manual cleaning of mixing chamber, rotor maintenance and sampling inspection. It combines dust-proof rear feeding and convenient front-side maintenance, ideal for production lines with frequent color and formula changes of multiple materials. Disadvantages: The front door design has more sealing surfaces, leading to slightly weaker dust control performance than pure back charging models. Supporting dust removal equipment is required for high-dust working conditions.

Q9: How to choose between the two feeding modes?

A9: Selection reference based on production material features: 1. Formulas with heavy dust such as carbon black, color masterbatch and calcium carbonate filler, or workshops with strict dust control requirements → Prioritize Back Charging. 2. Frequent color masterbatch replacement, shoe sole rubber, EVA foaming, frequent chamber cleaning and heavy manual operation → Prioritize Front & Back Dual Charging.

Q10: What is the complete standard operation process of ASFROM Kneader Mixer?

A10: A unified 6-step standard operating procedure applies to both feeding types: 1. Before Feeding: Ram lifted, mixing chamber emptied, machine on standby; 2. Feeding: Feed main materials and additives through front or rear port; 3. Mixing: Pneumatic ram descends to apply pressure, twin rotors perform differential shear mixing; 4. Secondary/Tertiary Feeding: Add auxiliary ingredients in batches for continuous mixing and dispersion; 5. Discharging: The entire mixing chamber tilts forward by 140° to automatically discharge finished rubber compound; 6. Reset: Mixing chamber returns upright, ram lifts up, ready for the next production cycle.
