Pneumatic Dry Mortar Packing Machine 8–15Bags/Min Open Mouth Bag Filling Machine

The pneumatic filling machine is a professional pneumatic quantitative packaging device independently optimized for various dry mortar materials, including plastering mortar, anti-crack mortar, waterproof mortar, thermal insulation mortar, gypsum mortar and inorganic insulation mortar. Adopting pneumatic power drive and fluidized filling principle, the machine replaces traditional screw and impeller filling structures, realizing low-abrasion, dust-free and high-precision quantitative packaging of powdery and fine granular mortar materials. It supports bag packaging of valve port bags and open-mouth bags, featuring stable operation, low failure rate and strong material adaptability, which is the core supporting packaging equipment for standardized dry mortar production lines.

• Pneumatic Driving & Low Material Damage: Adopts pure pneumatic power operation without motor stirring, effectively avoiding crushing and damage to lightweight mortar aggregates such as vitrified microbeads and expanded perlite, maintaining the original physical performance and thermal insulation effect of mortar raw materials.
• Dust-Free & Environment-Friendly Filling: Equipped with sealed filling port and pulse dust removal interface, it realizes closed filling, effectively eliminating flying dust during mortar packaging, meeting factory environmental protection production standards and improving workshop working environment.
• High-Precision Quantitative Packaging: Matched with high-precision weighing sensor and intelligent quantitative control system, it realizes automatic weighing, fixed-value filling and automatic bag stopping, with accurate metering and small error, ensuring consistent net weight of finished mortar products.
• Wide Material Adaptability: It can stably package various dry mortar products, including high-fineness powder mortar, fibrous anti-crack mortar, lightweight thermal insulation mortar and high-viscosity polymer mortar, without material blockage and segregation.
• Simple Operation & Low Maintenance: The whole machine has a simple structural design, fewer wearing parts and low operation failure rate. It supports automatic bagging, filling and discharging, reducing manual operation intensity and improving production efficiency.
• Strong Compatibility: Perfectly matched with small, medium and large dry mortar production lines, it can be used independently or connected with assembly line equipment to realize continuous and automated packaging operation.

• Dry Mortar Production Plants: Special packaging equipment for standardized production of plastering mortar, bonding mortar, anti-crack mortar, waterproof mortar and repair mortar.
• Thermal Insulation Material Factories: Suitable for packaging lightweight inorganic thermal insulation mortar, vitrified microbead mortar and perlite thermal insulation mortar, avoiding aggregate crushing.
• Gypsum Mortar Processing Plants: Adapt to packaging of self-leveling gypsum mortar, wall plastering gypsum mortar and bonding gypsum mortar, ensuring no caking and uniform filling.
• Building Material Supporting Production Lines: Supporting automatic packaging of various powdered building materials such as wear-resistant floor mortar, filler mortar and polymer functional mortar.
• Small and Medium-Sized Customized Production Workshops: Applicable for intermittent and mass packaging of various customized special dry mortar products.

• Before starting the machine, check the air pressure system, sealing parts and weighing sensor to ensure stable air pressure and no damage or leakage of equipment components.
• Prohibit putting foreign hard sundries into the feeding port to avoid blocking the fluidized filling channel and damaging the equipment.
• For lightweight and easy-stratification mortar materials, avoid long-term static storage in the silo before filling to prevent material segregation and affect packaging uniformity.
• Keep the workshop ventilation and dust removal system normally open during operation to ensure environmental protection and clean production.
• Regularly clean the filling nozzle and fluidized bed residual materials to prevent mortar moisture absorption and caking from causing filling blockage.
• Strictly operate in accordance with the specified air pressure range; excessive air pressure will cause material flying and bag expansion, while too low air pressure will lead to slow filling and inaccurate metering.
• Stop the machine and cut off the air source and power supply during equipment maintenance and shutdown for standby, and do not disassemble parts with electricity and air pressure.
• Regularly calibrate the weighing system to ensure packaging accuracy and avoid unqualified product weight.

Q1: What types of dry mortar is this pneumatic filling machine suitable for?

A1: It is suitable for almost all dry mortar products, including ordinary plastering mortar, anti-crack mortar, waterproof mortar, gypsum mortar, lightweight thermal insulation mortar, repair mortar and floor mortar. It is especially suitable for lightweight and fragile aggregate mortar that cannot be filled by traditional screw machines.

Q2: Why is the filling accuracy unstable during operation?

A2: The main reasons include unstable air pressure, sensor deviation, residual material blockage at the filling port, and uneven material fluidity. It can be solved by stabilizing air pressure, calibrating the sensor and cleaning residual materials regularly.

Q3: Will pneumatic filling damage lightweight thermal insulation aggregates?

A3: No. The equipment adopts fluidized pneumatic filling without rigid stirring and extrusion, which will not crush vitrified microbeads and perlite aggregates, and can completely retain the thermal insulation performance of lightweight mortar.

Q4: How to solve the dust flying problem during filling?

A4: The machine is equipped with a reserved dust removal interface, which can be connected with a pulse dust remover to realize closed dust-free filling. Regular inspection of the sealing ring of the filling port can also effectively prevent dust leakage.

Q5: What is the difference between pneumatic filling machine and traditional screw filling machine?

A5: The pneumatic type has no mechanical extrusion damage to materials, no material segregation, better sealing and dust-free effect, and is more suitable for high-quality and special mortar production; the screw type is easy to crush lightweight aggregates and cause material stratification.

Q6: Can the equipment support customized packaging weight?

A6: Yes. The standard packaging range is 20–50kg, and customized parameters such as 10kg small bag and 100kg large bag can be customized according to user production needs.

Q7: What is the daily maintenance work of the equipment?

A7: Clean residual materials of the filling nozzle and fluidized bed every day, check air pipe leakage and sealing ring wear, calibrate the weighing system regularly, and lubricate movable parts regularly to ensure stable operation.
