Mikro LGM^TMLong Gap Mill

The NEW Mikro-LGM™ long gap mill assures superior product quality and peak operational efficiency. Built upon the strength of Hosokawa’s unparalleled experience in size reduction, thermal processing and classification, the Mikro-LGM™ long gap mill is designed to meet the exacting demands of a wide variety of industrial applications.
Prior to the development of the Mikro-LGM™ long gap mill, materials had to be dried and de-agglomerated in two separate operations. For example, a rotary drum dryer was used to dry materials that had been wet milled.
A separate grinding/de-agglomeration process followed the drying operation.

The Mikro-LGM™ long gap mill is Hosokawa’s solution for streamlining these two operations into one continuous process. This type of dryer is commonly referred to as a “gap” type mill. It is called a “long” gap mill because of the long annular gap path the process material takes from the inlet to the discharge. By combining several operations such as flash drying, de-agglomeration and surface coating into one operation, a Mikro-LGM™ long gap mill eliminates the need for multiple material handling systems which subsequently increases process efficiencies. The dried powders often do not require any further size reduction. Both slurries and wet cake can be handled.

The Mikro-LGM™ modular design expands its range of applications beyond drying and deagglomeration. For dry grinding, modular options include: direct and independent drive classifiers; pre-grind rotor stage; an integrated jet mill and variable stage rotor design. The smaller size Mikro- LGM™ Long Gap Mills are engineered with a split body housing for easy maintenance and cleaning. The Mikro-LGM™ long gap mill processes high moisture materials in wet cake form as well as dry solid feed stocks up to one inch. Finished product particle sizes of D₉₇ < 10 microns can be achieved.

	Typical Applications Include:
	Mineral Fillers
	Carbon Black
	Pigments
	Chemicals
	PVC Resin
	Amorphous and fumed silica
	Foodstuff
	Minerals
	Cryogenic grinding of rubber and elastomers

The Mikro-LGM™ long gap mill has demonstrated superior performance over all other mechanical mills in reducing grit from pre-sized and agglomerated powders. Typical results are less than 1 part per million (ppm) residue on a 44 micron sieve starting from a feed stock with a residue of 120ppm.

This performance is achieved with a powerful grinding mechanism coupled with a precision internal air classifier. The air classifier is designed for a theoretical cut point of 2-5 microns, depending on the particle density. Rejected particles are forced away from the classifier wheel and redirected outside of the mill back to the material inlet using a patented re-circulation system.

	Design Options Include:
	Variable rotor height to diameter ratios
	Adjustable gap clearance
	Frequency controlled rotor drive
	Adjustable coarse extraction and recirculation device
	Independent or single shaft internal classifier
	Liquid injection device for coating application
	Pre-grinding rotor for large feed material

Drymeister Super Flash Dryer

Drymeister Super Flash Dryer

Drymeister Pilot Plant

Besides the existing Mikron Dryer types MDH and MDV, a new powerful flashdryer is available, called Drymeister (DMR)

This unique product allows grinding, classifying and high rates of evaporation to occur in a single step.
The totally enclosed system is designed for precise moisture control and uniform particle size even on heat-sensitive materials. The Dryer can work with cakes, slurries, gels and sols. The Drymeister can work in a closed loop with nitrogen, with heated air, steam or superheated steam.

	Features and Benefits:
	High overall heat transfer coefficient
	Uniform product characteristics
	Particle size/moisture control through PLC instrumentation
	Handles pastes or powders
	Short residence time
	Dust-free operation
	Space saving design Til toppen af siden
