Hosokawa has been manufacturing powder processing equipment for over 75 years and is a respected leader in toner processing.  We have been supplying equipment for the toner industry for over 20 years and have an installed base that spans the globe.  We possess a wide range of equipment to handle your process needs from premixing through grinding

Milling

There are various benefits in using Mechanical Impact mills for coarse grinding of toner materials. For one, it has D50 of 500 µm to 75 µm. Additionally, it is a highly energy efficient option with air cooling and simple cleaning mechanisms. It is also very diverse, with a large range of both equipment sizes and discharge sizes.

For fine grinding needs when handling toner materials, our Fluidized Bed Jet Mills also provide many benefits. It has D50 down to 5um. Additionally, the entire design of the mill is centered around toner processing. The size distribution is tight, with the classifier being vertically mounted with purge. It operates continuously, with constant bed weight through load cells. It is also easily accessible with simple cleaning mechanisms.

Classification

For classifying toner materials, Wheel Classifiers is perfect for your needs. It includes one or two stage ultrafine classifiers, with independent drive(s). Wheel Classifiers can help with ultra-fine dedusting of particles less than 2 µm. Its toner centric design includes the vertically mounted classifier wheel with purge. This design also allows for easy accessibility and simple cleaning mechanisms.

Blending

For different levels and contexts of blending needs for toner materials, we have different technology offerings and recommendations that are suited to your needs.

For low shear blending of toner, our Nauta® Conical Screw Mixer is ideal because of its gentle mixing/drying mechanisms, low power consumption, fast/complete discharge, easy cleaning capabilities, and specialized suitable design for vacuum drying.

For high shear post-blending needs, the Cyclomix or Nobilta is ideal because of their coating and embedment capabilities, mechanical seals are not located in the product zone, complete discharge, and simple cleaning mechanisms.

For sphericalization, the Faculty, Noblita, or Cyclomix. With these technologies, sphericalization to > 0.96, there are coating and embedment abilities, and there is simultaneous dedusting via Faculty.

Other

Hosokawa’s toner processing systems are designed to support downstream operations including dispensing, filling, and weighing, allowing toner products to be packaged into a variety of container types using multiple filling methods. Material collection is accomplished through a high-efficiency cyclone system rather than a traditional baghouse, achieving collection efficiencies greater than 98% while simplifying maintenance and enabling faster product changeovers between batches. Safety is integrated throughout the design, with available features including pressure venting, explosion suppression, and pressure shock-resistant construction to meet the demands of toner processing environments. Advanced system and process controls are provided through PLC-based automation, with options for equipment visualization, touchscreen operator interfaces, and integration with plant management systems, ensuring efficient operation, monitoring, and traceability across the entire production process.
