Two-roll mills

Heavy duty design for any customer application.

Many years of experience in this field are used to produce these devices. Full production control gives us a great advantage in this section of engineering. Buzulukhas its own foundry for rolls casting. The rolls from our own castings are fully machined in our machining shop. The surface hardness of the rolls is 500 ± 20 HBr at a depth of 10 – 15 mm. Our own cast iron process guarantees the best quality product.

Under surface drilled cooling channels are standard, but also rolls with cavity cooling are available.

With lower acquisition costs, shorter lead times and minimal maintenance, cavity rolls offer standard applications in many areas. On the other hand, when better temperature control and cooling are required, under surface drilled rolls are a the only alternative.

Main characteristics

Each two-roll mill can be equipped with various additional devices such as stockblender, cutting knives, drive configuration and arrangement, etc.

Safety is always designed in accordance with EU safety standard 1417.

Always designed according to customer needs.

Hydraulic gap adjustment meets maximum operational comfort and safety with a fast response to the required gap.

Hydraulic gap adjustment is a standard. It is suitable for both, independent drive arrangement as well as for one drive confuguration with friction gears.

Remark: Type 03876 is for laboratory use only.

The length of the rolls can be adapted to the customer’s requirements.

Cooling water flow is calculated at the base of the drilled rolls excluding the Stockblender.
