Vibration Tube Mill ENG - Grenzebach Maschinenbau GmbH

Mechanical Process
Vibration Tube Mill
Function
Grenzebach BSH Vibration Tube Mills operate according to the
vibromill principle, with three grinding tubes arranged at an angle
of 60°. The vibration is generated by a drive located between the
grinding tubes. The Vibration Tube Mill is driven via an electric
motor and universal-joint shafts that are connected to the
flywheels via three bearing assemblies. The forces generated by
the flywheels are transmitted to the grinding tubes via bridge
plates and cause the grinding bodies to hit each other so that
the feed material is comminuted by impact between the grinding
bodies.
Design features
Our Vibration Tube Mills stand out for their sturdy design. The
grinding tubes are rigidly connected via web plates. The triple
bearing system with self-aligning roller bearings provides for a
particularly stable support during operation. The mill proper is
equipped with antivibration mounts and rests on a sectional steel
frame. Parts subject to wear can be easily replaced by removing
the front-end covers or outlet heads.
Advantages
Grenzebach BSH Vibration Tube Mills achieve high and uniform
throughput rates while the risk of malfunctions is very low and
the mill requires little energy input. The mill can be operated in
both continuous and discontinuous mode. Highly wear resistant
materials ensure a long service life of the grinding bodies. The
use of special materials also allows the mills to handle aggressive
products and product temperatures of up to some 350°C.

Typical Applications
Our Vibration Tube Mills are used in the
building materials, ceramics and chemical
industries. They are suitable in particular
for dry and wet grinding of medium-hard to
hard, abrasive products, such as slag, ash,
fireclay etc.
Limits of Application
Grenzebach BSH Vibration Tube Mills
achieve throughput rates of up to 20 t/h,
depending on the feed material. Product
feed temperatures up to 350°C are
possible. At a feed particle size < 10 mm,
an end fineness of d90 = 50 µm can be
achieved, depending on the product quality.
