B. Material: alloy chilled cast iron LTH-H.

C. Hardness: 68-72HSD

D. Chilling layer: 10-20mm

E. Main bearing: 4 rows of radial roller bearings.

F. Bearing seat: cast after tempering, oil passage.

G. The temperature adjustment of the drum adopts high-quality rotary joints and stainless steel metal hoses.

4).Adjust the clearance device

A. Adjustment speed: 4.2mm/min

B. Drive motor power: 0.55Kw

C. 1#&2#&4# Roller gap adjustment can be adjusted at both ends at the same time or separately.

5). Rubber baffle

Adjustment gap: 700-1100mm, manual adjustment.

6). The width adjustment of the rubber cutter is manually adjusted, and the rubber cutter and the roller clutch are driven by the cylinder.

7). Reducer

A. Type: motor input, shaft output.

B. Lubrication device: oil bath lubrication.

C. Input coupling: Elastic coupling.

8). Rod pin coupling

The output shaft coupling of the reducer is connected with the rollers of the main engine by sticky pins, which is flexible, smooth and noiseless, and easy to maintain.

9).Lubrication system

A. Bearing lubrication: The system has an oil tank, including flow adjustment, oil temperature gauge, cooler, filter, etc., to control the flow and reduce the oil temperature to ensure that the lubricating oil is clean.

B. Thin oil lubrication pipeline.
