Powder filling machines can fill a wide range of powders and granules, both free-flowing and non-free-flowing. Free-flowing means a powder doesn’t stick together, like granulated sugar or table salt. They don’t get squished easily when more pressure is put on them; even when they are moved, they don’t keep their shape. On the other hand, powders that don’t flow easily, like powdered milk and brown sugar, can be pressed and still keep their shape.
Automatic filling machine for powder is classified into several types based on their design and automation level. They can be set up for either volumetric or quantitative filling. Some filling machines can only work with powders that flow easily or don’t flow easily, but others can work with both.
When buying powder filling equipment, it is important to consider these factors when choosing one for your application.
1. Product Properties
Powder filling machines can handle different types of powder or granules. Some are better suited to free-flowing powders, while others handle non-free-flowing products best. Aside from how your powder product flows, you should also consider its compressibility, stickiness, shape, and size.
2. Packaging Type
Choose how you will pack your powder product. You may use sticks, pouches, bags, cans, bottles, or any other type of container. For each kind of packaging, you need a different machine. Also, the container size will determine how much your machine can fill. So pick a powder filling machine that can work with varying masses of fill.
3. Production Needs
Each type of powder filling machine can fill a different amount of powder. Fully automatic powder machines are faster than ones that are only partly automatic. So, they are best for making big batches of powder filling. Both rotary and inline filling machines work the same way. Also, consider how much the machine’s hopper can hold to see if it will meet your production needs.
4. Control System
Some powder fillers can only be run by pressing buttons and flipping switches. Choose more advanced machines with a digital PLC control system and a man-machine interface if you want to have more control over the production process.
5. Driving System
The driving part of the powder filling machine gives the parts of the machine the force they need to move. Stepper motors, servo motors, electric motors, and variable frequency drives are all options that could be used. The most common of these five is the servo motor.
6. Machine Material
There are a lot of choices for the machine’s material, but it’s best to use materials that don’t rust or corrode, especially for the parts that touch the product. The best ones to use are #304 and #316 stainless steel.
7. Filling Accuracy
No equipment is perfect, but you need to make sure you buy one with a reasonable number of flaws. Filling machine manufacturers will include their machines’ filling errors or accuracy on the technical specs. Check to see if the machine has sensors, timers, detectors, or controls for filling. These parts help make sure that the fills are more accurate and precise.
Understanding the various factors to consider when buying a powder filling machine can help determine which machine will work best for your application. Machines are large investments; ensure to get the suitable machine to avoid compatibility issues in the long run.
