【Case Study】Achieving both cost reduction and ignition prevention for grinding powder.
Reduction of disposal costs and fire risk! The optimal centrifuge for polishing powder measures.
We received an inquiry from Company H, which operates in the metal processing industry, regarding their desire to "reduce the disposal costs of stainless steel polishing powder" and "prevent the risk of spontaneous combustion." The polishing powder contains a high amount of oil, and disposing of it as is increases weight and costs, while leaving it unattended poses a risk of spontaneous combustion. In response, we proposed a solution by equipping our belt-driven bottom-discharge centrifugal separator "DMNβ" with a special "Jingasa" attachment, allowing for the efficient feeding and de-oiling of the polishing powder. The high-speed rotation can remove oil within a few minutes, significantly reducing the weight of the waste and cutting costs. Additionally, the removal of oil also eliminated the risk of spontaneous combustion. We also proposed a fully automated discharge system in collaboration with a belt conveyor, achieving labor savings, improved safety, and reduced labor costs. After implementation, we received high praise from the customer, stating that "both costs and risks were resolved simultaneously."
basic information
【POINT】Special specifications for introducing abrasives into a centrifuge - Jin-kasa specification By providing a jin-kasa, it is possible to introduce solid abrasive powder, which is not in liquid form, into the basket. In a centrifuge without a jin-kasa, when abrasive powder is introduced into the basket, it falls down without sticking to the inside of the centrifuge basket. During discharge, automatic discharge can be performed by raising the jin-kasa. - Fully automated operation enables labor-saving and large-scale processing By performing automatic discharge with fully automated operation, the need for manual discharge is eliminated, leading to a reduction in labor costs. Additionally, since a basket-type centrifuge can exert forces hundreds of times that of gravity, effective oil separation can be achieved in a short time.

Applications/Examples of results
Stainless steel polishing powder contains a lot of oil, and if disposed of as is, it not only increases weight and recovery costs but also poses a risk of spontaneous combustion if left unattended, making it a troublesome byproduct. In response to an inquiry from Company H, we proposed a system that incorporates a specially designed hood on our belt-driven bottom-discharge centrifuge "DMNβ," allowing for the efficient input and de-oiling of solid polishing powder. Since it can remove oil in just a few minutes, the waste is lightweight, significantly reducing costs. Furthermore, the absence of oil eliminates the risk of ignition, enhancing safety. Additionally, an automated discharge system linked to a conveyor belt has achieved labor savings and reduced personnel costs simultaneously. Company H has highly praised us, stating that we have successfully balanced cost reduction with safety assurance.
