On the integral frame, according to the different dosage amount of each component, the dosage equipment is assembled with a number of storage hoppers (optional stainless steel) with different volumes, arranged in single row or side by side, and set up a number of stations according to the work process (a unified station can be arranged with a number of sets of storage and feeding devices), and dosage is made sequentially by the mobile weighing hopper on the guide rail.

When the batching equipment calls the formula to start the batch production, the mobile hopper scale moves along the guide rail and is accurately positioned, the unloading mechanism of multiple storage hoppers at the same station will carry out the quantitative feeding in the form of fast/slow feeding in sequence or at the same time respectively. When the quantitative weighing of each material is completed and the dosing accuracy meets the predetermined requirements, the mobile hopper scale advances to the next station or even the final station to continue dosing. The mobile hopper scale will open the feeding mechanism for unloading at the designated position, and the material will be transferred manually or automatically discharged to the next process.

Installed in the bottom of each storage hopper low limit level switch, combined with the material level status (related sound / light prompts) for manual dumping, more economical; automatic feeding: for powder using vacuum feeding can improve the efficiency of the material supply, but the cost of this way of equipment is more expensive.

According to the characteristics of the powder material, the feeding mechanism is generally used spiral Feeder or vibrating feeder, and respectively to take control of the spiral speed and amplitude of the way for fast and slow feeding. For the dust that may arise in the process of feeding, can be sealed or dust-proof treatment; when the material due to moisture caking and other reasons leading to poor fluidity, need to take arch-breaking or flow-assisting measures to speed up the feeding. The stainless steel weighing module with high precision and reasonable range is used to detect the weight of materials in time and start/stop the feeding control, which is transmitted into PLC through the weighing instrument TR700.

It consists of control cabinet and on-site actuator. Through the cooperation of PLC and TR700, the servo controller controls the stepping motor to run precisely to the designated work station and unload the materials accurately. The heavy oil dosage production line is set up with interlock in the program to ensure orderly and reliable operation of the moving/unloading mechanism during dosage. For the convenience of actual operation and maintenance, under the manual operation mode, personnel can operate each mechanism on the site through the lighted operation buttons on the stainless steel analog screen on the surface of the controller cabinet and observe the equipment operation intuitively.

Multi-material system through the touch screen installed on the HPS multi-material function, you can complete the site dosage control and formula weight collection, the site operator only need to carry out the necessary manual intervention, you can complete the entire production, to avoid human error, but also to improve production efficiency. The dosage software has rich functions such as production monitoring, formula management (strong confidentiality), batch statistics, alarms and report printing, which is very suitable for real-time and multi-task control. The weighing and Batching system can also upload the relevant production information to the data server or ERP through the matching communication interface to realize information sharing.
