Gimat solutions for plastic industry

In small-medium size plastic manufacturing companies, many operations could be automated, reducing manual handling and costs

Bulk Bag Unloading and conveying of PVC and Calcium Carbonate into multiple mixing vessels

Equipment:

  • Bulk-bag discharger
  • Flat bottom agitator
  • Flexible screw conveyors

Customer: Binders, primers and adhesives manufacturer

Customer requirement: Due to increased demand for a high-quality wall-paper adhesive the company who are a leading manufacturer of high-performance adhesives for a wide range of industrial applications, had a requirement to discharge bulk quantities of PVC and Calcium Carbonate from single use bulk bags into three process mixing vessels.

  • The customer needed to scale up their production and remove unnecessary manual handling of 25 kgs sacks of materials into process vessels.
  • Reduction of costs by using 1000 kg flexible bulk bags.
  • The two new bulk delivery systems had to have the capability to feed any one of three new process mixing vessels.
  • The system needed to be reliable and to operate at a minimum of 2500 kg per hour.

Gimat solution: The application was difficult as it required multiple conveyors to be utilised from a single bulk bag outlet(s) manifold to feed the individual process vessels. Space was also restricted due to the close proximity of the new mixing vessels to the bulk bag discharge frames.

  • The Calcium Carbonate bulk bag discharger needed to feed two out of the three new mixing vessels.
  • GIMAT supplied a flat-bottomed agitator for ease of product flow for the Calcium Carbonate using variable speed drive system to feed the powder into the variable speed drive flexible screw conveyors.
  • The PVC bulk bag discharger was fitted with a unique outlet manifold that would allow the system to deliver PVC into any of the three new process vessels.
  • The manifold was fitted with a level sensor to detect material was present in the manifold prior to discharging, in the event on an empty bag or no material present an audible alarm would sound.
  • Both systems had their own control panels which were integrated into the customers own control package.

This application featured a number of engineered solutions to ensure that the customer demands were met, GIMAT provided the mechanical installation and commissioning of both systems.
