Currently, those working within the traditional developing model of the plastics industry are looking for ways to address the rising cost of labor, recruitment shortages, and the prices of commodities. Some in the Chinese portion of the plastics industry feel that economic structures need to be optimized and upgraded, and the use of automatic conveying systems can help fill this need.

As an example of this potential, let’s take a look at a company within the Jiangxi province. The company is known for producing and processing numerous piping products, including power protection pipes, water supply pipes, and communication pipes, as well as pipes in the categories of MPP, PVC, and PE.

Additionally, the company utilizes a comprehensive scientific quality managing system, with a central conveying system being the focus of our study. That system includes:

  • 3 extruding lines
  • 9 vacuum hoppers
  • An 800T IMM

Due to the company’s use of particle raw materials in their processing operations, the total quantity used daily often approaches 20 tons.

This customer additionally is in possession of three SHD-100 units and seven SHD-200 units, with these used for the purposes of drying. SMH-24L vacuum hoppers and a vacuum pipe breaker is also installed. To properly regulate the air flow, a rubber diaphragm is utilized, allowing the flow path to open and close.

As part of the process, a central material distribution station, in this case a SMDS-3-6-2.5, and three MST-400s are placed into the conveying room, with the bottom of each MST-400 having an SBU-160-63-V installed. Some aspects to consider:

  • Since an IMM is 100m away from the conveying room in question, and since it has a large throughput, two roots blowers (of the model type SRB-100-V) are used, allowing for minor pressure change, consistent air flow, and low energy consumption.
  • With these features in place, the alternating working mode can help prevent motor breakdown. These two blowers work alongside SCSF-200-F-E which facilitates reverse cleaning following material suction, and preventing the blocking of the filter.
  • Additionally, the system is fitted with accumulator and overpressure protection, and dust can be collected to help aid the blower.

A PLC and HMI 12-station central controller station (in this case, SCCS-100-G-C-10.4) is used to oversee and monitor the total conveying system. Each of the IMMs are attached to an individual pipe to allow for the smoothest possible operation and to help prevent the blocking of material.

Following completion of the system, the company has spoken highly of the equipment, reporting no design flaws or malfunction issues and praising the system’s overall efficiency.

Moving forward, we believe these configurations for conveying systems can be quite beneficial for companies and we plan to keep them in mind during future work.
