I. 500L High-Speed Hot Mixer Main Unit
1. Cylinder Material: 304 stainless steel in contact with materials, polished inner wall to prevent material sticking, thickened wear-resistant bottom lining, and rounded corners to prevent powder accumulation.
2. Agitator: Three-layer high-wear-resistant blades, integrally cast, dynamically balanced, effectively breaking up powder lumps for uniform and stable mixing.
3. Drive Motor: Standard Siemens Bede motor, two models available:
◦ Dual-speed motor: High and low speed switching, cost-effective, meeting conventional mixing processes;
◦ Variable frequency motor: Steplessly adjustable speed, adaptable to diverse and high-precision mixing production needs.
Equipped with chain reduction drive and water-cooled sealed shaft head, effectively preventing dust from entering the bearings and extending equipment lifespan.
4. Heating Structure: The cylinder jacket uses circulating heat transfer oil heating, combined with an electric heating heat transfer oil furnace, ensuring precise temperature control and suitability for hot mixing processes of rubber and plastic powders.
5. Lid Opening Structure: Pneumatic quick-opening top cover, silicone overall seal, with a reserved dust removal connection interface.
6. Discharge Valve: Bottom-operated large-diameter pneumatic butterfly valve, ensuring fast discharge speed, excellent sealing, and no powder leakage.
II. 1000L Cooling Mixer Main Unit
1. Cylinder Material: 304 stainless steel polished cylinder, double-layer water-cooled jacket structure, rapid water cooling to prevent powder agglomeration due to temperature rise.
2. Mixing Structure: Low-speed, wide-range mixing paddle, gently agitates materials, ensuring uniform cooling and preventing material crushing damage.
3. Drive Components: Uses a Siemens Bede variable frequency geared motor, ensuring stable low-speed operation, equipped with water-sealed dustproof bearing seats, providing excellent dustproof sealing.
4. Feed Inlet: Precisely connects to the hot mixer's discharge port, with a fully sealed pipeline design to prevent dust leakage.
5. Unloading Mechanism: Side-mounted pneumatic butterfly valve for smooth discharge, compatible with various downstream conveying equipment.
6. Matching Accessories: Complete cooling water circulation piping and water temperature monitoring instruments.
III. Automated Control System
1. Adopts Siemens PLC control system with touch screen display for intuitive and convenient operation.
2. Fully automated integrated production process: Automatic feeding → Hot mixing and heating → Automatic unloading → Cold mixing and cooling circulation.
3. Three-level access control with password management: Differentiated access for operators, technicians, and engineers, ensuring more standardized equipment management.
4. Automatic alarm for equipment malfunctions, pop-up window indicating the cause and solution, automatic retention of operating records for at least 4 weeks.
5. Core electrical components: ABB frequency converter and Schneider low-voltage electrical components, ensuring stable performance and low failure rate.
