5 Fabrication and technical standards

5.1 Roller: made of Nickel, Chrome &Molybdenum chilled cast iron through

centrifugal casting. Roll surface hardened layer depth is up to 10-15mm,

hardness is around HS73±2.

5.2 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

5.3 Roll bearing lubrication: motorized auto grease pump.

5.4 Bearing house: made of cast steel or cast iron through anneal heating treatment and processing, with lubrication holes reserved.anneal heating treatment bearing houses

5.5 Nip adjusting device: motorized nip adjusting system, both single adjusting and multi-adjusting are available.

5.6 Frame: made of cast iron or fabricated through anneal heating treatment and processing.

5.7 Bedplate: integral welding structure, made of superior U steel and constructional steel through anneal heating treatment and processing.

5.8 Stock guider: fixed type.

5.9 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.

5.10 Roll temperature adjusting device: consisting of superior rotary joints and stainless steel pipe with drilled spraying nozzles.

5.11 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.

pulling rope/chest bar, foot pedal, safety protection bar are all available.

5.12 Stock pan: welded by superior stainless steel plate.

5.13 Main motor start up: Star-delta starting.

5.14 Cutter device: 2pcs manual straight cutter.

5.15 Stock blender: motorized or hydraulic type.Motorized type stock blender
