hole, with NEW ROTOFLUX rotary unions with spray lances
(Connections: 1" inlet; 11/2" drain)
Speed: Infinitely variable via potentiometer
Tight roller: 1 - 20 rpm = 2 - 25 m/min
Adjustment roller: 1 - 16.4 rpm = 2 - 20.5 m/min

Roller Bearings: 4 NEW Bronze Plain Bearings
- NEW silicone gaskets
Lubrication: Recirculating oil lubrication with electric pump
- NEW Electrical Flow Monitoring
Gap adjustment: Electromotive
- 2 NEW three-phase motors 1.5 kW
- NEW magnetostrictive displacement measuring system with digital
output of the roll gap via displays in the control cabinet door
- Overload protection due to fracture plates
Guide jaws: 2-piece steel material wiper jaws including centreboard
- Jaws are attached to the bearing housing and move along with gap
adjustment
- Manually swivelling
- Incl. safety switch for querying the working position
Material pan: Tray under the rollers
Strip cutter: Without strip cutter
Motor: NEW SEVA three-phase motor 45 kW, 400 V, 50 Hz, 1480 1/min
- With external fan
- Energy efficiency class IE3
- Motor is installed under the rollers to save space
Gearbox: spur gear, i=14:1, immersion bath lubrication
- NEW bearings
- NEW seals of the shaft inputs and outputs
- The gearbox is integrated into the right-hand stand to save
space.
Electrical control: RITTAL control cabinet (RAL 7035) incl. base, not
air-conditioned;
power section for gap adjustment; Service socket
- Siemens CPU S7-1214C in conjunction with programmable Pilz PNOZ
safety relay for all safety functions
- Separate control panel, rotatable, installed directly on the machine
frame (seen to the left of the operator)
- In addition to the touchscreen for operation, the operator also has
user-friendly conventional hardware buttons in the control panel
- Process displays (speed, gap, current consumption, utilization,
etc.) and messages via 7" Siemens SIMATIC HMI TP 700 Comfort touch
panel
- Incl. programming and visualization
- "Reduced speed" switch in the control panel, which automatically
reduces the speed of the roller to an adjustable value (e.g. so that
the operator can remove the strip); Switch is always available;
Pressing the switch again resets the speed to the previously set
working speed
- Additional "cleaning mode" function, which can be selected via a key
switch on the control panel.
In cleaning mode, the rollers can be rotated forward at reduced speed
using two-handed operation when the wiper jaws are raised, in order to
be able to clean the entire roller circumference and the jaws in a
single pass.
The safety devices are all armed.
- SCHNEIDER Altivar ATV 930 frequency inverter, designed for 55 kW
motor power
- Incl. Siemens router for remote maintenance of the machine (a
connection must be provided on site at the installation site of the
machine; for this we ask you to consult your IT department – if
possible before placing the order)
- 10 m cable length from the control cabinet to the machine
Power supply: Feed machine: 3x400 V + PEN, 50 Hz
Electrical cabinet lighting/socket feed-in: 230 V + PE + N, 50 Hz
Control voltage 24 V DC
Safety: Safety concept based on the requirements of EN 1417 and in
accordance with the checklist of BG RCI for rolling mills in the
rubber and plastics industry with a roller diameter ≥ 400 mm (latest
version as of 10.2018) for the adaptation of the risk assessment
(state of the art)
- Mechanically operated protective device with proximity response in
the form of a switch rod at the front and rear (height 1200 mm from
the operator's standing surface)
- NEW pneumatically operated disc brake, incl. clutch (drilled and
grooved), brake disc, brake caliper with monitoring and quick
bleeding, mounting bracket, FESTO pneumatic safety valve, maintenance
unit, pressure sensor, protective cover and brake emergency opening
device
(Due to their design, disc brakes have the property of remaining fully
effective even in the event of a power failure. This conversion makes
it possible to meet the requirements of the
Industrial Safety Ordinance, as disc brakes are now state of the art)
- Design of the brake D1161234 as a two-channel, redundant safety
function according to PLr = d, category 3 of EN ISO 13849-1:2008. In
the first stage, the rollers are stopped electrically by the frequency
converter and in the second stage by a disc brake between the motor
and the gearbox
- When the emergency stop is activated, the rollers stop (roller <
60°) and the rollers can be reversed by 45° per button press
(multiple reversals are possible).
- Automatic measurement and monitoring of the braking angle after
emergency stop
- Control circuit for automatic brake test to be carried out at least
weekly (separate for electrical and mechanical braking device) and
monitoring of the prescribed braking angles and test cycle; Prevention
of switching on of the main drives when the maximum permissible
braking angles and test cycle are exceeded
- Brake function given even in the event of a power failure.
Base plate: Compact steel frame on vibration-damping rubber mats
- The complete rolling mill is set up at ground level directly on the
hall floor. No foundations, no pits, no platforms required. This saves
costs during installation.
- Height of the top of the roller from the floor approx. 1320 mm
