cement bag filling machine

The cement bag filling machine is a specialized automatic packaging equipment tailored for dry-mixed mortar, cement and powder building material production lines. It is mainly used for quantitative filling and bagging of powdery and fine granular materials including ordinary cement, dry mortar, putty powder, gypsum powder and other building powder materials.

Integrating automatic bag placing, precise metering, quantitative filling and bag dropping functions, the machine realizes continuous and unmanned packaging operation. Matched with full-automatic and semi-automatic mortar production lines, it effectively solves the problems of low manual packaging efficiency, large weight error and serious dust pollution. With compact mechanical structure, intelligent control system and stable operating performance, it is the core supporting equipment for standardized and large-scale production of building powder materials.

• High Precision Weighing & Filling: Equipped with high-sensitivity digital weighing sensors and intelligent microcomputer control system, it realizes real-time monitoring and automatic correction of filling weight. The filling error is controlled within a small range, effectively avoiding material waste and unqualified finished products, meeting national standard packaging weight requirements.
• High Production Efficiency & Labor Saving: It supports continuous cyclic filling operation with fast feeding and bagging speed. The whole process from bag sleeving to filling and bag discharging is automated, which greatly reduces manual participation, cuts labor costs, and significantly improves the overall production capacity of the mortar production line.
• Excellent Dust Prevention & Environmental Protection: Adopts fully sealed filling structure and matched dust removal interface, which effectively suppresses dust overflow during the high-speed filling process. It improves the on-site production environment, meets industrial environmental protection standards, and reduces material floating loss.
• Stable Operation & Long Service Life: The main body is made of thickened high-quality steel plate through integral welding and anti-rust treatment. Key transmission and feeding parts are made of wear-resistant and high-strength materials, which are resistant to material impact and abrasion, ensuring long-term stable operation and low failure rate.
• Intelligent Operation & Easy Maintenance: Equipped with humanized touch control panel, the weight parameter, filling speed and other data can be adjusted freely with simple operation. The modular detachable structure is convenient for daily cleaning of residual materials, inspection and replacement of wearing parts, reducing later maintenance cost.
• Strong Compatibility & Wide Adaptability: It can be perfectly matched with various types of dry mortar production lines, cement mixing stations and powder processing equipment. It is adaptable for standard PP woven bags and composite packaging bags, and supports customized filling weight to meet diversified production needs.

Note: All parameters can be customized according to customer's on-site production conditions and material characteristics.

1. Before starting the machine, comprehensively check the power circuit, air pipeline connection, equipment fasteners and wearing parts. It is strictly prohibited to start the machine with faults, loose parts or pipeline leakage to avoid equipment damage and safety accidents.
2. Operators must receive professional operation training and be familiar with the equipment operation process and safety specifications. It is forbidden to extend hands or any foreign objects into the filling nozzle and operating area during equipment operation.
3. Ensure uniform and stable material feeding. Strictly prevent large impurities, iron blocks and foreign matters from entering the machine body, so as to avoid jamming of impeller, metering device and transmission components, which may cause equipment failure.
4. Regularly calibrate the weighing system every week. Re-calibration is required after sensor replacement, long-time continuous operation or equipment movement to ensure accurate filling weight and meet packaging standards.
5. Keep the equipment body and working site clean. Regularly clean the residual powder accumulated inside and outside the machine to prevent material caking and dust accumulation from affecting the normal operation and service life of the equipment.
6. All maintenance, inspection and cleaning work must be carried out after completely cutting off the power supply and air source, and hanging safety warning signs to prevent accidental startup of the equipment.
7. The working environment shall be kept well ventilated, and matched with professional dust removal equipment to reduce dust concentration, ensure production safety and meet environmental protection requirements.
8. It is forbidden to disassemble, modify the equipment structure and electrical control components without the manufacturer's authorization. Unauthorized modification will lead to invalid warranty and potential safety hazards.
9. Stop the machine in time in case of abnormal noise, material blockage and weight deviation during operation, and troubleshoot the fault before restarting the equipment.

• Dry-Mixed Mortar Production Line: Special filling and packaging for various finished mortars, including masonry mortar, plastering mortar, floor self-leveling mortar, waterproof mortar and thermal insulation mortar.
• Cement Processing Plant: Quantitative bagging of ordinary Portland cement, composite cement, slag cement and other cement products.
• Building Materials Factory: Packaging of powdery building materials such as wall putty powder, gypsum powder, talcum powder and calcium powder.
• Powder Chemical Industry: Quantitative filling of non-corrosive dry powder and fine granular materials suitable for building and chemical auxiliary materials.
• Small and Medium Processing Workshops: Supporting use with mortar mixers and powder mixing equipment to realize independent and efficient bagging operation of finished products.

Q1: What are the main reasons for excessive filling weight error?

A1: The common reasons include dust accumulation and pollution on the weighing sensor, loose sensor installation, unstable air pressure, unsmooth material fluidity and blockage of the filling nozzle. It is necessary to clean the sensor, fix loose parts, adjust the air pressure to the standard range, and re-calibrate the weighing system.

Q2: The machine runs normally but no material is discharged during filling.

A2: First check whether there is sufficient material in the upper silo and whether material arching or bridging occurs. Secondly, check whether the internal impeller and feeding components are stuck by foreign impurities. Cut off the power supply completely before cleaning blockages and troubleshooting.

Q3: Serious dust leakage occurs during the filling process.

A3: Check whether the sealing sleeve and dust-proof accessories of the filling nozzle are aging or damaged, and replace the failed sealing parts in time. Meanwhile, confirm that the supporting dust removal equipment is running normally to ensure effective dust absorption.

Q4: Can the machine adapt to different filling weights?

A4: Yes. The machine supports free adjustment of filling weight within the standard range of 20-50kg via the control panel. For ultra-range customized weight requirements, professional modification and debugging by the manufacturer is available.

Q5: What daily and regular maintenance work is required?

A5: Daily maintenance includes cleaning residual powder, checking air pipe and circuit connection; Weekly maintenance includes weighing system calibration and fastener inspection; Monthly maintenance includes checking the wear of key parts and lubricating transmission components to ensure stable equipment operation.

Q6: What types of packaging bags are applicable to the equipment?

A6: It is mainly applicable to open-mouth PP woven bags and plastic composite bags. Special valve bags need professional structural modification of the equipment to be used normally.

Q7: Why does the machine stop automatically during operation?

A7: Automatic shutdown is mostly caused by overload operation, material blockage, abnormal power supply or sensor failure. Please check the power supply voltage, clean internal blockages and inspect electrical components, and restart the machine after eliminating faults.
