Economic equipment! Solve problems at a minimal cost! Introducing case studies of Brodisk.

This is a case where we received a consultation from the person in charge at a PVC pipe manufacturing factory, stating that after changing the type of pigment, a rat-hole phenomenon began to occur in the small hopper of the pigment supply device. Based on the conditions we discussed, we informed them that there were no significant risks and proposed a model and layout. They implemented our suggestions immediately, and there have been no further troubles since then. The color abnormalities and color variations in the products that occurred during the initial troubles have not reappeared. 【Case Study】 ■ Before Implementation - Rat-hole phenomenon occurred in the small hopper of the pigment supply device. ■ After Implementation - No troubles have occurred at all. - No color abnormalities or variations in the products have occurred. *For more details, please refer to the PDF document or feel free to contact us. *Our website features numerous case studies.

0527 Rat hole measures in the upper hopper of the quantitative supply device.

The target material is a very poorly flowing fine powder, and while the substance name is undisclosed, upon reviewing the sample, it seemed to have properties similar to titanium dioxide. After reviewing the hopper diagram, the sample of the target material, and photos of the rat hole situation, we provided guidance on the arrangement and control of the blow disk, and it was adopted. I heard that the rat holes were resolved immediately after the installation of the equipment. [Overview of the hopper where the blow disk was installed this time] ■ Diameter: φ1000 ■ Bottom dimensions: approximately 500×500 ■ Height: approximately 700 *For more details, please refer to the PDF document or feel free to contact us.
