Rubber Mixing Mill Machine Rubber Mixer
Application: This 2 roller open mixing mill ensures the perfect and uniform
blending of natural and synthetic rubber with other raw materials.
The open mixing mill can mixall the raw materials to the desired
specifications.
Structural Features: 1. This open mixing mill can be equipped with hydraulic or
mechanical device which can automatically make the rubber material
be mixed over and over again. So the labor intensity and mixing
time can be reduced greatly.
2. The open mixing mill speed reducer is planetary speed reducer,
it is low noise, high efficiency, good transfer effect.
3. To ensure the safety of staff and equipment, we install
convenient button for emergency.
4. All the open mixing mills we provide to you are checked after
3-7 hours non-stop full load operation, perfect quality and low
noise. Customers can use them immediately after installation.

Advantage:
1)Roller: made of Nickel, Chrome &Molybdenum chilled cast ironThrough
centrifugal casting. Roll surface hardened layer depth isup to
10-15mm, hardness is around HS76±2.
2)Roll bearing and seal: 8pcs double-row cylindrical roller bearing is adopted coupling
with 4pcs more thrust bearing, 12pcs bearings for each machine,
which could save energy consumption up to 10-15%, lubrication
grease is reduced by 20-25%.2sets double-row cylindrical roller
bearings for each bearing house.
1set more thrust bearing outside the roller bearings
3)Roll bearing lubrication: motorized auto grease pump.
4)Bearing house: made of cast steel or cast iron through anneal heating treatment
and processing, with lubrication holes reserved.
anneal heating treatment bearing houses
5)Nip adjusting device: motorized nip adjusting system, both single adjusting and
multi-adjusting are available.
6)Frame: made of cast iron or fabricated through anneal heating treatment
and processing.
anneal heating treatment machine frames
7)Bedplate: integral welding structure, made of superior U steel and
constructional steel through anneal heating treatment and processing.
8)Stock guider: fixed type
9)Transmission system: complete enclosed drive, through couplings, gear reducer(single
input shaft and single output shaft), driving gear and friction
gear, main motor drives the two rolls relative rotating at
different speed, plasticating, mixing or sheeting could be
therefore realized.
10)Roll temperature adjusting device: consisting of superior rotary joints and stainless steel pipe with
drilled spraying nozzles.
11)Emergency stop and braking device: energy consumption method is used to stop the mill. There are
3-emergency stop buttons fitted on the frames, press the button if
any emergency situation occurs, the roll rotation will not exceed
1/4 circle and main motor reverse 1/4 circle thereafter within 2
seconds. Meanwhile, this mill is fitted with electrical-hydraulic
brake system, which improves equipment safety ability
significantly. Other safety device such as pulling rope/chest bar,
foot pedal, safety protection bar are all available.
12)Stock pan: welded by superior stainless steel plate.
13 )Main motor start up: Star-delta starting.
14) Cutter device: 2pcs manual straight cutter.
