Dry mortar packing machine have valve port type dry mortar bagging machine and open port type dry  mortar filling machine, the following details of the difference between the two type packing machine.

1. Valve port type dry mortar packing machine:

The valve port packer is very common in the product packaging of powder industry, such as cement, putty powder, ceramic tile adhesive , masonry mortar and other dry mortar packaging is widely used in the valve port packaging machine. The feeding form of the valve port packing machine is impeller feeding suitable for relatively small particles of material packaging. The composition of dry mortar is relatively complex, and the diameter range of particles and specific gravity are obviously different. In order to expand the packaging scope of the packaging machine as far as possible, improve the packaging accuracy, in the feeding speed to take the following measures:

The speed of the motor is regulated stepless by the frequency converter while the flow rate of the material in the feeding tube is regulated by the airflow. The whole process is completed by the microcomputer. The specific method is that in the initial stage of material filling, the impeller running at high speed will feed the material into the filling mouth, and the thrust force formed and the compressed air in the filling tube will propel the material into the packaging bag quickly. When the material is filled to about 70% of the required weight, the motor starts to slow down. Until the required packaging weight is reached, the air pressure of the flow aid decreases gradually. At the same time, the section of the canning pipe is gradually reduced under the action of the cylinder, until the end of accurate weighing and complete closure.

The improved valve port type dry powder mortar packing machine, due to the use of larger diameter filling pipe, accelerate the initial filling speed, reduce the phenomenon of pipe blocking, increase the scope of material adaptation, packaging speed; The multistage control of the flow velocity in the later stage can reduce the material flow velocity quickly and ensure the packaging accuracy. The packing mouth is equipped with dust cover to effectively reduce dust diffusion and improve the working environment.

Our company now produces the valve port packing machine impeller packing machine, airflow packing machine, air floating packing machine. Impeller packing machine packing dry powder and sand powder mixture, air flow packing machine and air floating packing machine can pack sand or slightly smaller viscosity materials. Customers can choose the dry mortar packaging machine according to the materials they want to package

2, open type dry mortar packaging machine

Open type packing machine, because the conveying machinery directly into the open bag, so will not produce material blockage problem, suitable for all kinds of dry powder mortar packaging.

The open type dry powder mortar packing machine produced by our company adopts spiral feeding form for material filling. The feeding screw controls the speed through the frequency converter. According to the flow performance of the material, the initial rapid filling reaches 70-90% of the whole bag, and the slow filling process enters until the set weight is reached.

The discharging port is designed as a double layer structure, conveying materials in the middle, interlayer is connected with the dust collector, which can discharge the gas in the pocket and the material can in time, and achieve good dust removal effect with minimal air volume.

The automatic bag clamping and bag dropping function can reduce the labor intensity and improve the measurement accuracy.
