This automatic cement packing machine is a valve-bag quantitative filling unit for cement and dry powder building materials. It adopts impeller feeding and gravimetric weighing technology to finish automatic bag loading, filling, weighing, bag releasing and conveying. It can be directly connected with the mixer, buffer silo, belt conveyor and palletizing machine to form a continuous automatic production line. It is widely used for packing ordinary Portland cement, composite cement, masonry cement, as well as dry-mixed mortar, putty powder, gypsum powder and lime powder. Stable weighing accuracy effectively reduces material overfilling and waste. With built-in dust extraction interface, it controls powder leakage and improves the working environment of cement and mortar workshops.
- High weighing stability: High-precision load cell and two-speed feeding control, fast coarse feeding + slow fine feeding to guarantee stable bag weight.
- Dust suppression design: Sealed filling spout and reserved dust collecting port, compatible with central dust removal system, low dust emission.
- Durable impeller feeding structure: Wear-resistant impeller for abrasive cement powder, long service life and stable feeding speed.
- Intelligent formula storage: PLC + touch screen control, multiple weight recipes stored for quick switching between cement, mortar and other powder products.
- Full safety interlock: Bag missing detection, overload protection, emergency stop, fault alarm and automatic stop function.
- Perfect line compatibility: Standard signal and discharge interface, easy to link with silo, mixer, conveyor and downstream palletizer.
- Low maintenance cost: Simple structure, convenient disassembly and cleaning of material contact parts.

- Only trained operators are allowed to run the machine. Do not put hands near the filling nozzle and clamping mechanism during automatic operation.
- The compressed air must be dry and clean. Install oil-water separator and filter to protect pneumatic cylinders and valves.
- Clean weighing sensor, filling spout, impeller and dust pipeline every shift. Cement dust accumulation will cause weighing drift and blockage.
- It is forbidden to modify weighing parameters, feeding speed and PLC program without permission. Parameter adjustment must be done by professional technicians.
- Check emergency stop, bag detection sensor and dust removal pipeline before startup. Shut down immediately once abnormal alarms appear.
- Regularly check impeller wear, bolts tightening, seal ring aging; cut off power and air supply before all maintenance work.
- Hard foreign objects such as iron scraps and stones are not allowed to enter the feeding cavity to avoid impeller damage.
- If cement spills or bags break during filling, stop the machine, clean all spilled powder and check sensors before restarting.
- Cement plant, cement packaging workshop for bulk cement bagging
- Dry-mixed mortar production line: tile adhesive, putty, plaster mortar, masonry mortar
- Building powder processing: gypsum powder, lime powder, fly ash, heavy calcium powder
- Automated building material factories, matched with silo, mixer and palletizer for full-line automation
- Factories with strict requirements for dust control and stable weighing quality
Q1: Can this cement packing machine connect with the mixer and palletizer we introduced before? A1: Yes. It is designed with reserved interlock signals and discharge conveyor interface. We can adjust the feeding rhythm and height to realize synchronous operation of mixing, packing and palletizing.
Q2: Can it pack both 25kg cement bags and 50kg dry mortar bags? A2: Yes. The weighing range covers 20–50 kg. You can save different product formulas on the touch screen and switch with one click.
Q3: How to solve cement dust overflow during filling? A3: The filling nozzle adopts sealed structure with reserved dust suction port, which can connect to central dust collector. Independent dust collector is available as optional accessory.
Q4: What is the difference between cement packing machine and dry mortar packing machine? A4: This cement packer uses impeller feeding, more suitable for high-density, good-flow cement powder. For ultra-fine mortar powder with poor fluidity, we can choose auger feeding version.
Q5: What is the warranty and after-sales service? A5: Standard warranty is 12 months from delivery. We provide installation guidance, commissioning, operator training and lifetime technical support. Wear spare parts can be supplied at factory price.
Q6: Can we customize bag size and machine layout? A6: Yes. We can customize nozzle size, bag clamping stroke and overall layout according to your valve bag size and workshop space.
