2017-11-25
Equipment Overview and Principle:
1. This machine employs a normal-pressure sulfur‑breaking plasticization process and a unique dual‑screw self‑cleaning control system, addressing the safety concerns and environmental pollution issues—such as wastewater and exhaust emissions—associated with high‑temperature, high‑pressure operations in conventional reclaimed rubber production. It utilizes electromagnetic heating, enhancing thermal efficiency and achieving substantial energy savings. The overall energy‑saving performance is significant. With continuous operation and a high degree of automated control, it reduces labor requirements, ensures stable product quality, and delivers strong overall economic benefits.
2. This equipment employs a normal-pressure, continuous sulfur‑breaking plasticization process. Vulcanized rubber powder is uniformly blended with softening agents and activators, then subjected to heating, holding at temperature, and cooling within a twin‑screw plasticizing extruder to produce recycled rubber powder. One of the twin screws reciprocates under hydraulic drive, effectively addressing the issue of adhesive buildup in conventional rubber‑powder processing equipment.
Scope of Application and Uses
1. Raw material type: various vulcanized rubber powders; raw material particle size: approximately 30 mesh;
2. Equipment applications: rubber desulfurization, regeneration, and plasticization. It delivers significant energy savings. The system enables continuous production, features a high degree of automated control, reduces labor requirements, ensures stable product quality, and yields substantial overall economic benefits.
Features:
1. The entire treatment process achieves truly zero emissions across all environmental control categories, including wastewater, exhaust gases, and thermal oil fumes.
2. Single‑machine plasticizing units can be operated in series, with the number of units configurable to meet specific requirements; multiple machines can run in parallel, allowing for continuous capacity expansion while sharing a common feeding system.
3. The main unit is driven by a variable-frequency motor, enabling adjustment of production rate and residence time of materials within the machine; it employs a dual-screw conveying system, with one screw powered by hydraulics to perform timed reciprocating motion, thereby preventing adhesion and carbon buildup.
4. Heating Method: Advanced industrial electromagnetic heating, offering high efficiency and energy savings, with clean and hygienic operation and no safety hazards. Multi-point temperature control divides the heating into four zones, each of which can be independently set to a specific temperature, enhancing thermal efficiency and promoting rational energy conservation.
5. Preheating time: From the start of heating to reaching 280°C, it takes only 20–25 minutes, significantly reducing electricity costs, labor expenses, and losses associated with pre‑charging materials.
6. Cooling Time: The machine cools rapidly upon shutdown, reaching a safe temperature within 15 minutes, and shuts down completely when power is cut. This eliminates the issue of prolonged downtime caused by thermal inertia, ensuring that production can be halted without leaving personnel on site.
7. Operational Safety: The operating environment is safe, with no high‑temperature points outside the machine to prevent personal injury. There is no risk of equipment oil leakage contaminating circulating water or cooling materials; optional discharge temperatures can be maintained below 50–80°C.
8. Operational Efficiency: Equipment malfunctions can be repaired immediately, eliminating the severe production delays caused by waiting two days for the system to cool down due to thermal inertia.
