Frequently Asked Questions
What processes are normally included in a TSR 10/20 natural rubber line?
A complete TSR 10/20 line normally includes raw-material breaking and washing, squeezing and dewatering, creping or granulation, trolley filling, drying, bale unloading, baling, inspection, packaging, and palletizing. The exact configuration depends on feedstock condition, product specification, target capacity, and existing equipment.
What equipment can be included in an automatic natural rubber packaging line?
The line may include a bale unloading robot or unloading machine, an automatic feeding baling press, automatic wrapping machine, metal detector, bale internal inspection machine, bale inverter, conveying system, automatic bagging machine, and palletizing robot. The configuration should match the dryer cycle, bale specification, and inspection process.
Why do rubber factories in Africa usually need more kneading, creping, and granulation equipment?
African cup lump is often naturally coagulated and stored for longer periods. Its surface can harden while internal moisture becomes more difficult to remove. More mechanical kneading and dewatering stages, and sometimes longer drying time, may therefore be required. Equipment quantities should be confirmed through feedstock tests and capacity targets.
Why is pre-cleaning often needed at rubber factories in Africa?
Some feedstock accumulates mud, sand, and other contaminants during storage and transport. Pre-cleaning reduces the cleaning load on downstream tanks and equipment and helps avoid stoppages caused by frequent cleaning. The actual process is configured according to feedstock cleanliness.
Why use multi-stage creping and granulation instead of only one stage?
Multi-stage creping and granulation helps form more uniform, loose rubber crumbs and improves drying conditions. Repeated creping without suitable granulation and loosening may make the rubber sheet increasingly dense and adversely affect drying.
Why may a 5 t/h line use 610 mm rollers instead of smaller rollers?
For the same processing objective, a larger roller diameter can provide a longer rubber-contact path at a lower rotational speed, which supports mechanical dewatering. Final roller diameter must still be selected according to feedstock, capacity, roller surface, and drive design.
What does a four-hotspot drying line contribute to natural rubber drying?
Its design objective is to improve hot-air volume and temperature distribution inside the drying cabinet for more uniform low-temperature drying control. Actual effects on throughput, plasticity retention, and energy use depend on project conditions and continuous operating data.
Why should Southeast Asian rubber factories also use multi-stage kneading, creping, and granulation where possible?
Although cup lump in Southeast Asia is generally easier to dewater than cup lump in Africa, using three kneading stages and two creping and granulation stages requires only a limited increase in equipment investment and can improve line capacity and reduce production cost.
How should a large rubber factory choose among a hot-air furnace, steam boiler, and thermal-oil boiler?
When biomass or coal is used as fuel, the rubber dryer can be configured with a hot-air furnace, steam boiler, or thermal-oil boiler. A hot-air furnace supplies heat to the drying chamber using hot air as the heat-transfer medium, while steam or thermal-oil boilers use steam or thermal oil. Hot air has a large volumetric flow and its supply temperature fluctuates more than that of steam or thermal-oil systems. Therefore, when stable heat-supply temperature is required, a steam boiler or thermal-oil boiler should be preferred.
What advantages does Sinyoung offer in automatic natural rubber packaging?
Sinyoung has more than 30 years of experience in natural-rubber production equipment and understands the details and bottlenecks of the process. Since 2015, Sinyoung has developed automatic feeding, baling, and packaging equipment and accumulated substantial line-application experience. For example, the cycle time of bale unloading must be coordinated not only with the unloading operation but also with the drying-cabinet cycle and drying-trolley circulation so that the complete line remains balanced.
