Operation of the Rubber Filtration Machine 1. In accordance with production process requirements, heat the machine body and screw before feeding material for filtration; do not start the extruder or feed material while it is still cooling. 2. When starting up and feeding material, begin with a small amount and gradually increase. After the equipment has been running, reheat or cool it as needed to meet production requirements. 3. During continuous discharge, after discharging approximately 10 batches of rubber, open the die head to replace the filter screen. If the rubber contains excessive impurities, appropriately increase the frequency of filter‑screen changes. 4. The wire mesh must be laid in two layers: one layer of 8 mesh/24.5 mm and one layer of 80–100 mesh/24.5 mm. 5. When stopping production,

Operation of the Rubber Filter Press

1. In accordance with the production process requirements, heating of the barrel and screw must be completed before feeding and filtration; starting up and feeding under cooled extruder conditions is strictly prohibited.

2. When feeding materials into the equipment, start with a small quantity and gradually increase it. After the equipment has been running, it can be reheated or cooled as required by the production process.

3. During continuous material discharge, after 10 truckloads have been discharged, the screen at the machine head must be changed. If the material contains an excessive amount of impurities, the frequency of screen changes may be increased accordingly.

4. The wire mesh shall be laid in two layers, with specifications of one layer of 8 mesh/24.5 mm and one layer of 80–100 mesh/24.5 mm.

5. When stopping production, first cease feeding; the machine may be shut down only after it has completely discharged any remaining rubber compound.

6. Temperatures of various equipment components are as follows:

Take natural rubber as an example: the rear of the machine is at 35–60 degrees.

The front of the fuselage is at 60–90 degrees.

The nose angle is 90–110 degrees.

However, due to differences in formulation, the temperature of each section can be adjusted flexibly during use.

7. After shutdown, the water inlet valve must be closed to drain the cooling water from the barrel.

8. It is strictly prohibited for steel fragments, foreign objects, or small tools to fall into the feed inlet, as this may damage the screw and barrel.

9. During operation, strictly prevent the screw from reversing to avoid disrupting normal equipment function.

All equipment should be run under no-load conditions for a period of time, and only after all bearings have been adequately lubricated may it be put into loaded operation.

2. During operation, the operator shall monitor the gearbox temperature at appropriate intervals. If the gearbox temperature exceeds 70°C or the oil temperature exceeds 90°C, the equipment must be shut down immediately. The cause must be identified and the fault rectified; only after the fault has been resolved and the lubricant replaced may the equipment be put back into service.

3. During operation, the surrounding environment must be kept clean to prevent foreign matter from contaminating the rubber compound.

4. This machine must not be run idly without material. During no-load testing, mechanical oil must be added to the barrel, and the screw should not be allowed to rotate idly for more than 5 minutes to prevent damage to the barrel and screw.

5. During operation, the temperature of the bearings and the reducer shall not exceed 70°C.

6. When operating the extruder, never overload it by overfilling with resin to prevent equipment damage caused by excessive load.
