Expert knowledge and vision

Your innovation advantage:air classier technology

by Christian Peier.

Since 1925, our company has been

developing high-quality components

or grinding plants. When Christian

Peier put his rst air classier into

service in 1939, this was a revolution

in quality management or his cus-

tomers. For Christian Peier Beck-

um, or simply CPB, this was the start

o a success story that continues up

to the present day.

Today the solutions evolved by Chris-

tian Peier are based on compre-

hensive process know-how. Our inter-

nationally acknowledged innovations

and progressive developments are

landmarks or the market. The Opti-Tromp product range is currently

the latest stage in classi-

er technology, led by the

tried and tested QDK

cross air fow cage

classier. CPB

classiers play a

decisive role in

guaranteeing the

quality o your

nished product,

enhance your mill’s

eciency and reduce

its specic energy con-

sumption.

The OptiTromp amily:high perormance

or bulk materials.

As a member o a strong group

o companies specializing in mill

and classiers technology, we

oer you much more than high

eciency air classiers or bulk

materials. We also oer solutions

or special applications culminat-ing in the ultra-ine classier JS

designed or pigments.

Our high eiciency air classiers

are an assurance or the quality o

materials such as

• cement

• rawmeal

• coal/petcoke

• quartzsand/blastfurnaceslag • graphite/flyash

• gypsum

• lime

• ironore

• feldspar

• wollastonite

• ferro-silicon

Our OptiTromp product range

includes ive dynamic classier

with a powered rotating cage.



The classier’s ocus:its classication eect.

An air classier divides material

fow into two parts. One o them

consists o ne material, the other

one o coarser parts. Centriugal,

gravitational and fow orces im-

pact on mass elements which are

o dierent sizes and use natural

laws to bring about classication.The “tromp curve“ illustrates how

eciently the materials are classi-

ed: The lower the deviation rom

the vertical, the more precise the

sharpness o classication. The

lower the deviation rom the hori-

zontal line, the greater the classi-

cation eect.

Function and efciency

Clean classication by physical orces: In the classi-

ying area, the material is classied by centriugal

and fow orces: coarse grain is pushed to the side

walls, ne grain is pulled inwards.

Depending on customer and material demands it

is possible to reach a product neness with a cut

point o d97 = 80 µm up to 15 µm and o 25 µm

reaching into the submicron area (< 1 µm).

A clever concept:the core o each

Christian Peier

air classier.

Christian Peier’s high ecien-

cy air classiers are designed in

such a way that the material-to-

be-classied arrives at the distri-

bution plate by two diametrical-

ly arranged eeding chutes. Due

to the high speed o rotation, the

material is then pushed to the side

walls. In this process, any possi-

ble agglomerates disintegrate be-

ore the dissolved material alls

into the classiying area below.

In alling, the material is caught

by a horizontal airfow which car-

ries the smaller particles through

the rotor blades into the rotat-ing cage. From there, they are

either carried to cyclones or

are classied as ne ma-

terial through a lter

system. During this

classiying pro-

cess, heavy par-

ticles are not

caught by the air

fow but all into

the coarse mate-

rial cone.



Conned air seal:wear-ree thanks to air

cushion.

In Christian Peier’s classier’s

concept, it is the conned air seal

which plays a very special and

very successul role. Mounted be-

neath the rotating cage, the con-

ned air seal oers you many

advantages compared to conven-

tional solutions like, or exam-

ple, the labyrinth seal. The big-

gest advantage: The conned air

seal does not wear out. This is due

to a special construction: the ad-

justing ring and the rotating cage

do not touch each other, they are

separated by a small gap. Air is

pressed into this gap making it

work like a cushion and providingsmooth operation. When escap-

ing between the sealing rings,

the air prevents dust and

coarse-grained mate-

rial particles (over-

sized particles)

rom entering.

Technology and details

Strong lining.

An unbreakable protection.

In order to guard against wear, we do not only optimize

material guiding. Additionally, we supply all parts

o our classiers subject to high velocities

o eed material with long-lasting lining or

wear protection. By doing this, a chemically

bound cemented ceramic protects the dis-

tribution plate, the lateral parts o the dis-

persion zone, the nes discharge tube as well

as the casing parts beneath the classiying zone.

Especially stressed areas o air guide vanes and rotating

cage rods are equipped with extremely wear resistant

hard material linings. In the grit cone, constructively

planned material build-ups serve as autogenous protec-

tion.

Consistent distance through

precise gap adjustment



Maximum economy:even during maintenance.

For us it is important to keep

the maintenance o our classi-

ers as simple as possible. For this

reason, the bearing cartridge in

Christian Peier‘s high eciency

air classiers is installed outside

the dust-loaded zone o the rotat-

ing cage. During maintenance itis removed in ull, with the rotat-

ing cage remaining in the classi-

er. All o the classier‘s compo-

nents can also easily be reached

through ample-sized inspection

doors.

For you the advantage is that worn

parts can be quickly replaced,

keeping non-operation periods at

a minimum and ensuring economic

and continuous operation.

Smooth drive.

Reliable and long-lasting.

CPB high eciency air classiers are smoothly driven by

V-belts. Depending on motor capacity, the belt pulley

starts moving either directly or with a reducer unit.

Our decision to opt or this construction was made con-

sciously and has proved its worth or many years through-

out the world. It is o low weight. It needs extremely low

maintenance. It has a very long lie, with virtually no signs

o wear on the V-belts ater years o operation.



The standard version:ts into any grinding

plant.

A classier circuit, easy and o

low maintenance or applications

that need no cooling. Christian

Peier‘s high ecieny air classi-

ers are standardly equipped with

circulating air ans and cyclones

or nes separation. Classiers o

this standard design can be inte-

grated into almost any grinding

plant.

Classier with cyclones



Cooling included:classiers with lter

system.

In cases where the basic materi-

al is hot or special requirements o

material temperature have to be

met, we use a lter system instead

o cyclones.

In this system, the temperature o

the nish material is given and the

system initially started in a closed

circuit. I the sensor detects nomi-

nal temperature in the materi-

al fow, the resh air damper (C)

is opened up step by step in or-

der to let resh air in. The exhaust

air damper (B) regulates itsel.

The recirculating air damper (A)

is regulated automatically by thepressure in ront o the classier.

For maximum cooling, the whole

classiying air is replaced by resh

air. In this process, nish product

temperatures o less than 70 °C

can be reached.

TGS:the compact twin

o the QDK

The TGS Top Gas Classier uses

the same successul process tech-

nology as the QDK. Eciency and

operating principle are identical.

The most important dierence:

the TGS is more compact. The n-

ish product is discharged above

the rotating cage. With this addi-

tion to the successul QDK, Chris-

tian Peier oers you more fexi-

bility in the choice o the optimum

solution or your plant design. The

TGS has proved especially valua-

ble in the modernization o exist-

ing grinding plants. It is installed

when there is not sucient space

or a QDK.



DSL:tried and tested in

air-swept mill systems

worldwide.

With the DSL, dynamic air classi-

er, the material eeding is eect-

ed through the classiying air fow

rom the bottom. This solution has

proven successul in the greatest

variety o customer plants world-

wide. Primarily, the DSL is used

or closed systems in grinding

plants or petcoke or coal and or

the grinding o raw meal.

OptiTromp amily



DSM:suitable or all

vertical mills.

The dynamic classier minerals,

DSM, was designed or the use in

vertical mills. The air fow comes

rom below which makes the DSM

the ideal choice or products with

relatively low humidity.

Christian Peier designs and in-

stalls each DSM to adjust to the

corresponding mill product and

the necessary air quantity.

OptiTromp amily



DSK:the individual solution

or humid materials.

Christian Peier also plans and

designs customized dynamic clas-

siers. One o these is the DSK

which is oten used or vertical

coal mills. It was developed or

the classication o coal, petcoke

and urther products with rela-

tively high humidity.

Its high classication eciency

means that the DSK can also meet

stricter industry requirements

regarding NOx limits. For explo-

sive materials, the DSK is available

as shock pressure resistant ver-

sion.The vertical arrangement o

the central eeding chute prevents

material coating o humid materi-als. It conveys the eeding mate-

rial directly on the grinding

table o the vertical mill.



Technical centre and laboratory

Accurate raw data:a reliable basis or

your decision.

Christian Peier provides you

with reliable raw data or your in-

vestment decision. All the param-

eters necessary or the successul

operation o your grinding plant

are calculated in semi-industrial

tests. Computer based simulation

systems as well as the laboratory

analysis o raw materials and

nish products are an integral

part o our planning and design-

ing phase. Our teams cultivate an

intensive exchange o knowledge

and close collaboration with

technical colleges and universi-

ties. This collaboration enables us

to cut corners and implement in-novative solutions or you. It also

led to remarkable results in

the development o new

basic materials.



Innovation and R&D

Motivated to innovate:Research anddevelopment.

We continually strive or optimi-

zation, or urther and new deve-

lopment. We are assisted in this

by laboratory analysis, simula-

tions and testing plants. Christian

Peier’s innovations are put into

eect by our research and deve-lopment division on the basis o

precise scientic ndings. This

method has also shown the way

orward in the development o

customer-oriented solutions. Ater

commissioning, the eciency and

reliability o our developments are

tested and attested by our labora-

tory – and conrmed by our cus-

tomers.



Years o experience:in the eld oengineering, too.

Over the last decades, we were

able to build on our experience in

the development o classier tech-

nology with the addition o com-

prehensive expert knowledge and

engineering know-how. Since the

early 1990s, we have been plan-ning and building turnkey grind-

ing plants as well as system com-

ponents and customized solutions.

In this process we tackle the most

complex challenges. The conver-

sion, optimization and upgrading

o existing grinding plants are an

integral part o our service. We o-

er solutions or all your projects

that are economically sound and

calculated down to the smallest

detail. I required we can take on

the entire project, rom planning

and development through to as-

sembly and commissioning.

Our service:eciency that stands

the test o time.

Ater the start-up, we ensure a high

eciency grade o the machines,

systems and plants installed by us

through regular inspections. Addi-

tionally, we will inorm you about new

innovations that will enhance your

plant‘s productivity even urther. But

that’s not all: even, i we have only

delivered and installed single compo-

nents - upon request, we arrange or

a complete plant check and optimi-

zation to get the maximum ecien-

cy rom your plant. Should a break-

down occur, we will check or you i

it makes sense to opt or a partial or

repair solution instead o buying new

equipment.
