Doctor Unit Assembly

Double Disk Refiner  Twin refining zones give it more than twice the capacity of the same type of refastener
Hydraulically operated plate blade clearance
allows for ideal refining and automatic follow-up.
Able to reduce the higher levels of friction and
contact between metal parts that occur during high load operations.
Use of roller coupling protects the runner
floating function.
Blade changes can be done easily.


Refining Plate
Ample blade types for the best match with the kind of stock
being refined.

Blade types based on the following criteria.
[1] Stock types
[2] Throughput
[3] Consistency
[4] Freeness drop

The hydraulic unit console
The unit includes an operation pressure gauge,
a main electric motor ammeter and switches for main electric motor operation,
shutdown, operational pressure fluctuations, stator pressurization,
run-out alarm, throw-open, operational power, etc.
The standard unit console 1 has a hydraulic mechanism incorporating a throttle valve,
pressure regulator, and open pressure directional valve.
The hydraulic unit is a compact device fitted to the top of the hydraulic tank with an independent
hydraulic source as in the above-mentioned standard console.
It consists of a relief valve, oil cooler, electric motor, vane pump, and pressure gauge.

Load Regulator Mechanism
Prevents metal touch during pressurization by remote operation.
Reliable load control made possible in light load operations.
Able to reduce the higher levels of friction and contact between metal parts that occur during high load operations.
Safe freeness control becomes possible thanks to indicator light from free-nester.
