impeller packing machine

The impeller packing machine is a professional quantitative valve-bag packaging equipment specially designed for dry powder and granular building materials. It adopts impeller forced feeding and mechanical metering principle, perfectly matching dry mortar production lines for packaging tile adhesive, cement, wall putty powder, plastering mortar, waterproof mortar and other powdery products.

Equipped with mature PLC intelligent control system and high-precision weighing sensing module, the machine automatically completes bag sleeving, quantitative filling, constant-weight metering and automatic bag dropping. Different from screw packing equipment, the impeller feeding structure features stable discharging, strong anti-blocking ability and uniform material flow. It realizes high-efficiency, dust-reduced and standardized packaging operation, effectively reducing manual labor and material waste, and serving as core supporting equipment for dry mortar factory mass production.

• Stable Impeller Feeding & Anti-blocking:Adopts optimized impeller rotary feeding structure with large material passing space and strong material adaptability. It effectively avoids blockage caused by slightly damp mortar powder, caked fine powder and granular mixed materials, ensuring continuous and smooth discharging.
• High-precision Quantitative Weighing:Matching high-sensitivity digital weighing system with real-time weight monitoring and automatic compensation function. The packaging weight error is controlled within ±0.2kg, ensuring uniform net weight of each bag of tile adhesive and dry mortar products, compliant with international sales measurement standards.
• High Packaging Efficiency & Labor Saving:Fast and stable rotary filling operation, with hourly output up to 180–320 bags. The whole process from filling to bag dropping is automated, only requiring 1–2 workers for auxiliary bag sleeving, greatly improving production efficiency and reducing labor costs.
• Sealed Dust-proof & Eco-friendly:Full sealed filling cavity and reserved dust removal interface, supporting negative pressure dust collection. It effectively suppresses powder overflow during packaging, reduces material loss, keeps workshop environment clean and meets environmental protection production requirements.
• Intelligent & Easy Operation:Adopts PLC + touch screen integrated control. Packaging weight, operating speed and delay parameters are adjustable visually. It supports automatic fault alarm, over-weight and under-weight reminder, with simple operation and low worker learning threshold.
• Durable Wear-resistant Structure:The impeller and material contact parts are made of high-strength wear-resistant steel after special anti-corrosion treatment. The whole machine features rigid thickened steel structure, low failure rate and long service life, adapting to long-term uninterrupted industrial operation.
• Wide Material Compatibility:Suitable for all kinds of dry powdery building materials, including tile adhesive, dry mixed mortar, cement, putty powder, mineral powder and thermal insulation mortar. It supports free switching of multiple mortar formulas with strong versatility.
• Low Maintenance Cost:Simplified mechanical structure with fewer vulnerable parts and modular design. Daily cleaning and parts replacement are convenient, effectively reducing later maintenance time and operating cost.

• Carry out comprehensive pre-start inspection every time. Check the tightness of machine fasteners, the flexibility of impeller rotation, the sealing performance of filling nozzle and the sensitivity of weighing sensors. Remove foreign hard sundries inside the machine to prevent impeller jamming and equipment damage.
• Ensure stable and dry compressed air supply. Regularly drain water and filter impurities in the air source to avoid failure of pneumatic bag clamping and unloading components, which will affect packaging stability and weighing accuracy.
• Set standard packaging weight and operating parameters through the touch screen according to production requirements. Professional technicians shall complete regular weighing calibration; unauthorized modification of system internal parameters is strictly prohibited.
• Ensure raw materials are dry and loose without massive caking and hard impurities. Severely agglomerated mortar materials must be crushed before feeding to prevent impeller blockage and abnormal discharging.
• Operators must receive professional training before taking post and wear dust-proof protective equipment. It is forbidden to open protective covers or touch rotating impeller and running parts during equipment operation.
• Follow standard startup and shutdown procedures. Start the dust removal system first, then run the machine with no-load pre-operation for 3–5 minutes. Stop feeding first when shutting down, and turn off the main machine after all materials are completely discharged.
• Thoroughly clean residual powder and adhered materials on the impeller and material channel after daily shutdown to prevent material caking, which may affect discharging speed and weighing accuracy of the next batch.
• Perform regular equipment maintenance, including lubricating transmission bearings, checking circuit and pneumatic system stability, and replacing worn nozzles and sealing parts in time. Cut off power and air supply completely before maintenance and overhaul.
• Keep the workshop dry, ventilated and flat. Long-term humid environment is prohibited to prevent raw material moisture caking and rusting of internal mechanical and electrical components.

• Dry Mortar Production Lines:Special automatic packaging for tile adhesive, plastering mortar, masonry mortar, waterproof mortar, crack repair mortar and other dry mortar finished products, perfectly matching full-automatic mortar production lines.
• Cement & Building Powder Factories:Quantitative packaging of ordinary cement, composite cement, mineral powder, quartz powder and other cementitious and powdery building materials.
• Decoration Material Enterprises:Suitable for mass packaging of wall putty powder, decorative mortar, bonding powder and other decorative building powder materials.
• Environmental Protection New Material Plants:Applicable for packaging various functional mortars such as thermal insulation mortar and self-leveling mortar, adapting to diversified new material production.
• Medium & Small-sized Building Material Processing Plants:With small footprint, stable performance and low investment, it is ideal supporting equipment for small and medium-sized dry mortar factories.

• Q1: What is the advantage of impeller type packing machine compared with screw type? A1: The impeller feeding structure has larger material passing space and stronger anti-blocking ability, more suitable for slightly damp mortar and granular mixed materials. It features more stable discharging, lower failure rate and simpler maintenance, which is more suitable for long-term continuous dry mortar production.
• Q2: What causes unstable weighing and large weight errors? A2: Common reasons include uncalibrated weighing system, unstable air pressure, impeller material adhesion and blockage, aging nozzle sealing, or abnormal dust removal negative pressure. Regular cleaning, calibration and pneumatic system inspection can solve the problem effectively.

• Q3: Can the machine pack different products such as tile adhesive and putty powder alternately? A3: Yes, it has strong material compatibility. When switching different mortar formulas, thoroughly clean the impeller, material channel and filling nozzle to avoid cross-contamination and ensure finished product quality.
• Q4: How to solve impeller blockage during operation? A4: Immediately stop feeding and cut off power and air supply. Manually clean caked and accumulated materials on the impeller. Strictly prevent hard sundries from entering the machine during feeding to avoid repeated blockage.
• Q5: How many workers are required for normal operation? A5: Only 1–2 workers are needed for bag sleeving and finished bag collection. The whole processes of quantitative filling, weighing and bag dropping are completed automatically by the machine, saving a lot of labor costs.
• Q6: How to reduce dust overflow during packaging? A6: Ensure the matching dust collector works normally and maintains stable negative pressure. Check and replace aging sealing gaskets regularly, and keep the filling nozzle closely fitted with the bag mouth to eliminate dust leakage.
• Q7: What are the key daily maintenance points? A7: Clean residual materials on the impeller and material channel daily; check air pressure and circuit stability regularly; calibrate weighing accuracy weekly; lubricate transmission parts monthly. Standard maintenance can stabilize operation efficiency and extend equipment service life.
