Powder and granular materials are used and support us in many parts of life. These materials each have different properties, and some are difficult to discharge.
Yoshikawa develops equipment that can smoothly feed all kinds of materials.
With its know-how and technology, Yoshikawa solves feeding problems that were once unsolvable.
The Circle Feeder is the only product that can overcome powder and
granular material feeding problems that are considered too difficult.
The Circle Feeder has overcome a number of feeding challenges and has been the savior of many powder and granular material feeding processes, with more than 10,000 units delivered to users.With our unique technology, Yoshikawa is determined to take up new challenging issues to meet the expectations of customers.
Problem with airtight specifications
The facility requires airtightness inside the feeders but there was no feeder that could meet this requirement.Airtight requirements can be accommodated by the Circle Feeder.
Problem with stable feeding
Lithium-ion battery manufacturer
The Circle Feeder allows stable feeding even if the materials are difficult to process, and even in the event of changes in the materials’ properties caused by undergoing diverse production processes.
Problem with high-precision proportional mixing
Plastic board manufacturer
The Circle Feeder is used to avoid the problem of segregation and can mix materials at constant proportions.
Problem with bridging
Flour milling company
Bran is difficult to feed stably as it tends to bridge inside the hopper when stored in large quantities.The Circle Feeder prevents materials from clogging and bridging.
Problems with difficult-to-discharge materials
Recycling industry of food waste from food businesses
Food waste is difficult to store and feed due to its moisture content and its glutinous and adhesive properties. The Circle Feeder achieves stable storage and feeding of food waste.
Problem with large storage
Biomass power generation industry
Wood chips for biomass power generation are prone to bridging in silos due to their moisture content.With its unique mechanism, the Circle Feeder enables the storage of wood chips in large silos.
