SHR-50 High-Speed Turbo Mixer | PVC, PE, PP, Masterbatch & Additives

SHR-50 High-Speed Turbo Mixer Introduction:

The SHR-50 is a compact high-speed turbo mixer in which material is heated and homogenized by its own motion. Paddle blades rotating at up to 1440 rpm throw the batch along the vessel wall and force a continuous up-and-down circulation; the resulting inter-particle and particle-to-blade friction raises the temperature rapidly — ideal when resins must absorb liquid plasticizers, or when pigments and additives must be dispersed and coated.

Construction & Working Principle:

The unit consists of a base frame, mixing vessel, vessel lid, transmission, lifting arrangement, discharge outlet and electrical control cabinet.

• Mixing vessel — welded stainless steel; inner surface hardened, smooth, wear- and corrosion-resistant, non-sticking; insulation layer on the outside.
• Vessel lid — stainless steel, inner face precision-turned and polished; two heat-resistant rubber seals, Ø70 mm exhaust port and one liquid-atomizing connection. Open gently to avoid knocking the wall.
• Deflector plate — upper-inner wall, 35° angle, intensifies mixing; carries the thermocouple for temperature display and automatic discharge.
• Agitator & drive — paddle set driven by the motor via V-belt pulleys; clockwise rotation keeps material moving along the wall while circulating up and down.
• Motor — single-speed motor with variable-frequency control: press Start, turn the regulator to change speed.
• Discharge unit — stainless steel casting with pneumatic discharge door, cylinder and door in-line; reliable clamping, good sealing, flexible opening. Needs one 0.39–0.49 MPa air compressor (customer-supplied). Discharge controlled automatically by material temperature or manually.
• Main shaft — bearing-supported; upper part carries three paddle sets. Friction heat raises material temperature quickly, improving resin absorption of plasticizer. Machined stainless blades — wear- and corrosion-resistant.

Core Advantages of High-Speed Turbo Mixing Machine:

• High-shear vortex mixing: Three-layer paddle set plus a shell-type deflector plate (35° to the wall) for strong tumbling action.
• Friction heating + jacket: Self-heating (typical PVC range 100–125 °C), 900 W electric heating jacket and circulating-water cooling.
• All SUS 304 contact parts: Ra 0.8 surfaces, mirror-polished SUS 201 outer cladding.
• Triple dynamic balancing: Blade / set / blade+shaft+pulley, accuracy ±0.2 g for smooth running.
• Automatic temperature discharge: In-vessel thermocouple; discharge by set temperature or manual button.
• Reliable drive train: 42CrMo quenched shaft, 3 × C-type heavy belts with mechanical tensioner, imported TTO labyrinth seals.

Applications Across Industries:

1. Plastics & Polymer Compounding

• PVC dry-blending: Suspension PVC resin + plasticizers, heat stabilizers (lead/Ca-Zn), lubricants (PE wax, stearic acid), CaCO₃ fillers; friction heating (100–120 °C) drives liquid additives deep into the porous resin.
• Color masterbatch & additives: High-shear dispersion of pigments, UV stabilizers, flame retardants, anti-static agents into PE/PP/ABS before pelletizing.
• Devolatilization & pre-drying: Moisture/VOC removal from regrind or hygroscopic powders before extrusion.
• Wood-Plastic Composites (WPC): Wood flour/fibers + polymers + coupling agents; moisture driven out to prevent voids.

2. Fine Chemicals & Powder Coatings

• Powder coatings: Epoxy/polyester resins, curing agents, flow additives, pigments pre-mixed before twin-screw extrusion.
• Battery electrode powders: NMC, LFP, graphite with conductive carbon additives.
• Detergents & dyes: surfactants, bleaches, optical brighteners, dyes without agglomeration.

3. Construction & Building Materials

• Dry-mix mortars & wall putty: Cellulose ethers, RDP, hydrophobic agents, quartz sand in cement/gypsum bases.
• Fiber-reinforced composites: PP or glass fiber distribution without balling or fiber damage.

4. Food, Cosmetics & Pharmaceuticals

• High-shear emulsification: Creams, lotions, ointments; liquid–solid suspensions.
• Wet granulation & tablet formulations: APIs + binders, disintegrants, excipients.
• Food powder blending: Instant beverages, milk powder, spices, seasonings.

Application–Function–Mechanism

SHR-50 High-Speed Turbo Mixer FAQ:

Q1: What materials can the SHR-50 handle?

A: Powder/powder and powder/liquid high-speed blending: PVC resin with plasticizers and stabilizers, PE/PP/ABS masterbatch premixes, WPC fiber blends, powder-coating premixes, battery electrode powders, dry-mix mortars, and food or pharmaceutical powders — all contact parts are SUS 304 with Ra 0.8 surfaces.

Q2: How is the material heated, and how hot does it get?

A: Primary heat is friction: at up to 1440 rpm, particle-to-particle and particle-to-blade rubbing raises the temperature quickly — typically 100–125 °C for PVC dry-blending, enabling plasticizer absorption. The jacket adds an optional 900 W electric heating mode; circulating water in the same jacket provides cooling.

Q3: What is the batch size and mixing time?

A: 50 L total / 37 L working volume; one cycle takes about 8–15 minutes depending on the formulation. An in-vessel thermocouple feeds the controller, so discharge can be automatic at set temperature or manual.

Q4: What utilities does the machine need on site?

A: 380 V / 50 Hz power (customizable) for the 11 kW VFD-controlled motor; compressed air at 0.39–0.49 MPa for the pneumatic discharge door and lid opening (one customer-supplied compressor); circulating water if cooling is required.

Q5: How is the agitator kept reliable and balanced over time?

Height-adjustable three-layer wear-resistant paddle locked by double SUS 304 nuts; each blade individually high-speed balanced, the set re-balanced, then blades+shaft+pulley balanced together to ±0.2 g; 42CrMo quenched shaft on ZWZ/HRB bearings with imported TTO labyrinth seals and 3 heavy C-belts with mechanical tensioner.
