The relationship between diameter,

length, speed and conveying

capacity play a decisive role when

it comes to designing screw

conveyors. The table should

provide you with assistance for

your design. Product-specific data

also influences these values.

We are more than happy to advise

you regarding this matter.

Centre bearing

Stainless steel divided hanger bearing housing with multiple

disk clutch

We can supply you with divides centre bearing units with a

flexible multiple disk clutch in a stainless steel design that we

have specially developed. The multiple disk clutch offsets the

alignment errors and minimises trunnion and bearing load.

The centre bearing unit is adjusted to the size of the desired

screw tube.

The table as stated above should provide you with assistance for your design. Product-specific data influences the stated values. We are more than happy to advise you regarding this matter.

Elevators

Elevators or bucket conveyors are continuous

conveyors for the vertical, dust-free conveying

of bulk materials.

We manufacture made-to-measure elevators

as a versatile and economic means of transport

for continuous conveying with a wide range of

application opportunities.

Our elevators are equipped with the latest

safety components (speed monitors, misalign-

ment sensors, backstops and full indicators)

and, as a special construction, are suitable for

application in explosive areas.

Sizes and conveying capacity available on

request.

Vertical conveyors

The vertical transport of bulk material is guaranteed with our vertical conveyors.

They can be used for many purposes and different products and have a low space

requirement. We provide you with a tailor-made solution for each product and all

capacities.

We are your partner when it comes to

the construction and supply of continuous

mixers and batch mixers.

In close collaboration with you, we also

develop the suitable application for your

mixture.

In doing so, the customer is able to

influence the mixing process at all times

by changing the paddle and speed.

Mixing technology

Our product range includes:

Single shaft mixers

Double shaft mixers

Quadruple shaft mixers

Cone screw mixers

Double cone mixers

Dwell time mixers

Kneading mixers
