APPLICATION TESTING CENTRE

The design of a grinding and classification system is

normally based on results from a programme of trials

conducted in the HOSOKAWA ALPINE Test Centre.

The trials can be complex and time consuming and

can include evaluation of a wide range of machine

options. This way, customers can be assured that all

process options have been considered and that the

system offered represents the optimum solution.

Our test centre is extensively equipped with a wide

range of different grinding and classification systems,

available both on a laboratory and production scale.

The test facility is supported by a modern testing

laboratory that includes a wide range of analytical

equipment enabling accurate measurement of

particle size, particle shape, density, etc. Skilled

and vastly experienced Alpine Engineers conduct

the trials, recording all operating data that enables

ongoing discussions with the customer during the

trial. Upon completion of the trial a comprehensive

test report is prepared which can then be used for

system design and as the basis for a performance

guarantee. It is essential that test facilities are kept at

the leading edge of technology if optimum baseline

data is to be provided for system design. Our range of

machines and systems is continuously upgraded and is

extended by new developments.

ALPINE WET PROCESSING

ALPINE AGITATED BALL MILL AHM

AGITATED BALL MILL AHM

The AHM is available in sizes suitable for

the laboratory, the testing centre or for

large-scale production.

This agitated ball mill was specially

developed for suspensions with good flow

properties where a steep particle size

distribution and high end-product fineness

are demanded. The mill is suitable for both

continuous operation and for batch mode

in the case of closed-circuit grinding.

PRINCIPLE OF OPERATION

The product is fed to the mill inlet by

means of a suitable pump and exits the mill

through a screen at the machine outlet.

The grinding chamber is filled to a level

of approximately 70-80% with grinding

pearls and the purpose of the screen at the

outlet is to retain the pearls whilst allowing

the milled slurry to exit the mill. Rotating

stirrers prevent blockage of the screen.

OPERATION

The mills are equipped with stationary or

mobile support units that guarantee simple

dismantling for cleaning and maintenance.

There is sufficient space underneath the

grinding chamber to permit the use of

large-volume collection bins for emptying

and cleaning the mill.

An agitated ball mill with a horizontal and cylindrical grinding chamber that is universal in use for the continuous wet grinding of particles down to the submicron range.

PROCESS TECHNOLOGIES FOR TOMORROWSM 6 / 7

The slotted screen separating element is

low-wear in design and is installed in the

mill axis. It comprises a screen holder and a

slotted pipe screen which can be exchanged

easily and quickly without having to empty

the mill. Rotating stirrers in the separating

zone relieve the screen dynamically and

prevent blockages.

A robust, double-action mechanical seal

with sealing-liquid unit guarantees a high

level of operating reliability.

WEAR PROTECTION

The AHM has a cylindrical, double-walled

mill housing that can be cooled. The inside

of the grinding chamber is lined using

sleeve sections in either hardened stainless

steel or polyurethane. This modular concept

enables rapid exchange of the lining and

offers such advantages as inexpensive spares

and flexible application possibilities.

The material of construction for the

agitator discs, separating rings and stirrers

is selected to suit the individual application.

Because of this, a long service life can be

achieved even if abrasive suspensions are

processed. Again, the individual components

have been designed with flexibility and cost

optimisation in mind.

When extremely high demands are placed on

the products with regard to contamination,

the rotor and stator parts can be coated

with either high-grade ceramics or tungsten

carbide.

ALPINE WET PROCESSING

ALPINE POWERPAINT DPP

ANNULAR BALL MILL

POWERPAINT DPP

When it comes to the dispersion efficiency,

ease of cleaning and cooling efficiency, the

Alpine PowerPaint DPP has been designed to

fulfil the highest demands. It is suitable for

processing solvents as well as suspensions of

high viscosity. In addition to applications

in the paint industry, the excellent cooling

capability and ease of cleaning make the

DPP mill well suited to pharmaceutical and

foodstuffs applications.

PRINCIPLE OF OPERATION

The product is introduced centrally into

the mill by means of a pump and exits the

mill via a rotating slotted screen through

the hollow shaft in the upper section of

the mill.

The geometry of the mill is annular in

design and the toroid-shaped gap is filled

with grinding pearls. Return channels

within the mill are located such that a

uniform distribution of the grinding pearls

within the grinding gap is achieved at any

operating speed, thus ensuring that the

separating zone is kept

free from blockages.

OPERATION

The PowerPaint DPP is characterised by

its ease of operation. Main features are

the simplicity and speed of emptying the

grinding pearls, as well as the ease with

which the mill can be dismantled under

application of the integrated lifting and

swivel unit. The slotted screen can be

exchanged without the necessity to remove

the rotor. The fact that the mill can be

cleaned with a very small amount of a

suitable fluid makes for fast enables rapid

changeover of products

This ball mill was specially developed for use in the paint and varnish industry to grind and disperse high-grade water-based and solvent-based paint systems and pigment dispersions.

PROCESS TECHNOLOGIES FOR TOMORROWSM 8 / 9

WEAR PROTECTION

As a result of the toroid-shaped annular

geometry, deflection zones with narrow

radii where grinding pearls could possibly

block up and cause high local wear are

avoided. The optimum motion of the

grinding pearls results in a long service

life of the machine components, i.e. of the

wear-protection elements. A robust, double-

action mechanical seal with sealing-liquid

unit guarantees a high level of operating

reliability.

Sintered carbide materials ensure excellent

wear protection and a long service life. The

easily accessible grinding chamber walls and

rotor surfaces can also be flame-sprayed

with tungsten carbide.

The wear-protection materials are

characterised by their excellent thermal

conductivity; a prerequisite for intensive

cooling of the grinding chamber.

Generously dimensioned cooling zones

both at the stator and the rotor permit the

gentle processing of temperature-sensitive

products such as water-based varnishes and

lacquers. Over and above this, all product-

contact materials are also suitable for

operation with solvents.

The compact design of the PowerPaint DPP

permits an extremely flexible set-up as well

as easy integration into existing systems.

ALPINE AGITATED BALL MILL DISCOPLEX ADP

AGITATED BALL MILL

DISCOPLEX ADP

The closed-circuit grinding of superfine

products is the main application for this

mill.

PRINCIPLE OF OPERATION

The Discoplex is a highly flexible agitated

ball mill in terms of it’s ease of operation

and the wide range of materials of

construction available for the wear

protection of the grinding chamber and

rotor. The construction materials of the

stirrers and grinding chamber lining can be

freely selected in different combinations.

Just as with the PowerPaint, the product is

pumped centrally into the mill housing and

exits the mill via a screen and a hollow shaft

in the upper section of the mill.

The rotor is disc-shaped in design and has

agitators that ensure uniform motion of the

grinding pearls.

WEAR PROTECTION

The two levels upon which the separating

element and the grinding pearls are located

as well as the internal circulation of the

grinding media prevent the grinding pearls

from compacting against the discharge

screen. The screen can can be installed

in any of the different mill designs to be

rotating or stationary.

The grinding chamber lining can be of

tungsten carbide or elastomers. Thanks

to their simple form, the stirrers can be

made rom a wide range of materials and

combined freely with the material used for

lining the grinding chamber and rotor.

The Alpine Discoplex is a ball mill that was specially developed for autogenous grinding, for highly viscous products and for dispersion tasks.

AGITATED BALL MILL ANR

The open construction of the ANR permits a

robust and simple design that allows large

machine sizes to be built. There are neither

separating elements nor shaft seals, the

result being optimum operating reliability.

The open design permits the grinding pearls

to be topped up easily during continuous

operation.

PRINCIPLE OF OPERATION

The product is charged to the lower section

of the mill by means of a suitable pump

and exits the mill via an overflow in the

upper section of the mill. Special production

parameters ensure that the force of gravity

retains the grinding pearls in the mill. The

grinding pearls are set into motion by

a ceramic-coated agitator. The standard-

design stator is also lined with ceramic to

ensure a long service life and to prevent

product discolouration.

The large-volume design coupled with

operation at low speeds permits the

production of superfine products at low

power consumption.

All ANR models can alternatively be supplied

with a hydraulic motor. This facilitates mill

start-up, permits the speed to be adjusted

and makes it possible to use much lower

installed motor power values.

The agitated ball mill ANR is an attrition mill in conventional open design. The mill is ideal for grinding mineral powder suspensions of medium viscosity at high outputs. It is used for single-pass grinding in continuous operation.

ALPINE WET CLASSIFIER HYDROPLEX AHP

WET CLASSIFIER AHP

This wet classifier is especially suitable

for high-tech products as well as for the

separation of relatively small product

batches of standard products or products

with sensitive surfaces. Typical applications

are ceramics, pigments or abrasives.

The wet classifier is equally suitable for

operation as a stand-alone classifier for pure

separation tasks of for operation in circuit

with a wet mill. Its flexibility is its forte.

PRINCIPLE OF OPERATION

The product is pumped into the bottom

section of the classifier and is separated

into a fine fraction and a coarse fraction

by means of a deflector wheel. The fines

pass radially through the classifying wheel

and exit the classifier via the hollow shaft.

The coarse material is discharged from the

classifier housing by means of a suitable

coarse material pump.

OPERATION

The classifier can be opened and dismantled

easily by means of the integrated hydraulic

lifting unit. Thanks to the modular design,

the wear parts are simple and inexpensive

to exchange.

Long years of experience with classifiers led to development of the Alpine Hydroplex AHP wet classifier.

WEAR PROTECTION

The AHP wet classifier can be lined with

a number of different wear-protection

materials. The wheel can be in ceramic

design and the housing can be lined with

polyurethane, tungsten carbide or ceramic.

The classifier is also suitable for processing

solvents.

The working range constitutes particle sizes

under 200 µm. Cut points of between

approx. 2 and 5 µm are possible. The cut

point is essentially influenced by the specific

weight of the solid. The higher the density,

the finer the cut point. Separations are

possible with solids concentrations of up

to 30% weight. If dispersion agents are

used, even higher concentrations can be

processed.

By varying the speed and throughput rate,

the AHP can be employed over a wide

particle size range. The end products can

thus be optimally adapted to changing

market demands.

Because of its simple geometry, the AHP is

quick and easy to clean and can thus also be

employed for different product lines on an

alternating basis.

LABORATORY MILL 90 AHM

LABORATORY MILL 90 AHM

This mill is ideal for small product batches

and for development tests, including those

in the field of nanotechnology. Extremely

small grinding pearls (<0.4 mm) can be used

in this mill and tests on the stabilisation of

suspensions in the submicron range can be

performed.

PRINCIPLE OF OPERATION

In contrast to the other AHM models, the

laboratory version has a variable-speed

direct drive and a generously dimensioned

flat screen deck. To permit filling and

emptying, the mill is suspended in pivots on

a frame. The upright position also allows a

cleaning of the screen without emptying

the mill.

WEAR PROTECTION

The wear parts of the basic machine are

exchangeable and can be made of stainless

steel, ceramic, tungsten carbide, polyurethane

or other plastics.

OPERATION

The high degree of flexibility results from

the possibility of equipping the mill with

grinding bins and agitator shafts in different

lengths. This makes it possible to adapt the

mill to different grinding bin volumes and

to process batches of 250 ml, 500 ml and

1100 ml.

Clamp rings guarantee ease of cleaning and

dismantling. A high degree of operating

reliability is achieved with the double-action

mechanical seal.

The 90 AHM is the laboratory mill in the AHM series and is designed as a table-top mill with separate control cabinet.

GRINDING PEARLS, TECHNOLOGY ANDCONSTRUCTION MATERIALS

WEAR-PROTECTION MATERIALS

We use a variety of different materials to

line our mills if highly abrasive products are

being ground. To guarantee a long service

life, we employ high-grade polyurethane,

selected steels or ceramic materials, as well

as coatings with tungsten carbide or other

materials that have a favourable influence

on the grinding process.

GRINDING PEARL SEPARATION

The fact that the grinding pearls do

not compact together is an important

advantage with all our mills. With the AHM

mill, rotating pins ensure that the batch of

grinding media remains loose and separate

around the screen, whereas with the ADP

and the DPP, it is the special mill geometry

and the subsequent circulation of grinding

pearls that ensures smooth and trouble-free

operation. The rotating screen in these mills

also brings an additional optimisation in

the case of highly viscous products.

GRINDING MEDIA

We work with a selected number of reputable

grinding media manufacturers who we

have no hesitation in recommending. The

quality of the grinding pearls is extremely

important for the entire grinding process

and a prerequisite for trouble-free mill

operation, because abraded media

particles can naturally adversely affect the

Besides the mill design, there are a number of other factors that make a major contribution to the success of a grinding process, namely the type of grinding media used, the wear-protection materials, the separation of the grinding pearls and naturally also the process as a whole.

(material, size, etc.) to suit every grinding

process, and we work in close cooperation

with our customers to ensure selection of

the ideal media for their application

Optimum wear protection and suitable

grinding pearls ensure that these mills have

a long service life.

The two illustrated AHM agitator ball mills

are generally operated independent of each

other in closed-circuit mode. The selected

configuration, however, is so flexible that

these mills can also be series-connected. This

brings advantages if different products are

being processed and also offers redundancy

with respect to the availability of the

grinding system.

The suspension is mixed in a bin before

being pumped by a hose pump through the

mill and back into the bin again. Over the

running time of the grinding operation, this

results in a specific number of theoretical

passes through the mill that influence the

grinding process.

We also offer different options as regards

the system control. Dependent on customer

requirements, a PLC unit with different

control circuits can be installed to monitor

the entire system. Our control systems can

be designed for incorporation into existing

systems, enabling monitoring of our process

at the central control station. Ask us about

the various options!

SYSTEM EXAMPLE: MINERAL SUSPENSIONS

WET GRINDING

LOW-VISCOSITY SUSPENSIONS

The system shown is designed for a classic

application, i.e. for grinding superfine

calcium carbonate slurries for the paper

industry. The suspension is prepared in

the mixing bin and introduced via a feed

bin to the mill by means of an eccentric

screw pump. The safety screen prevents

coarse contaminants from ingressing the

end product. Preliminary dry milling with

an Alpine table roller mill AWM is shown

as an option. For other mineral powder

applications there is added an impact

drying with an Alpine long gap mill to the

wet milling.

We offer different electric monitoring

options for all our system concepts.
