The fully automatic small chemicals weighing and dosing system is divided into the rectangular fully automatic small chemicals weighing and dosing system and the micro automatic calculation scale. 

There are many kinds of semi-automatic small chemicals batching systems. At present, there are many common structures in China, such as disc-type semi-automatic small chemicals batching system, linear semi-automatic small chemicals batching system, elliptical type semi-automatic small chemicals batching system and container type semi-automatic small chemicals batching system. 

The so-called semi-automatic means that the process of the materials from the storage hopper to the weighing scale is manual operation, while all other operations (automatic location, rotation, positioning of the storage hopper, prompt of weighing display, automatic transmission and positioning of the material frame, etc.) are automatically completed. 

To make it simply understood, if semi-automatic, the weighing is manually completed; if fully-automatic, the weighing is also automatically completed.
