Vertical mixer for plastic granules

Vertical Mixer for Plastic Granules

Description:

A Vertical Mixer for plastic granules is an industrial blending machine designed to homogenize plastic raw materials, such as LD, HD, PP, PVC, PET, or recycled granules. It features a vertical cylindrical design with a central mixing screw that rotates at high speed to lift and mix the granules evenly. These machines are highly efficient, compact, and suitable for both virgin and masterbatch mixing.

Where It’s Used:

• Plastic granule manufacturing plants
• Injection moulding units
• Extrusion lines
• Blow moulding industries
• Compounding and recycling plants
• Masterbatch & colorant processing
• Film blowing units
• Pipe and profile manufacturing units
• Roto moulding facilities
• Thermoplastic rubber industries

Uses:

• Uniform mixing of virgin and regrind plastic
• Color masterbatch mixing with raw polymer
• Pre-blending additives, UV stabilizers, or fillers
• Pre-drying and moisture removal (with heater attachment)
• Recycled plastic homogenization
• Blending granules before feeding into extruders or hoppers
• Preventing material layering in silo or hopper
• Improving product quality by consistent material feed

Importance:

• Ensures uniform color and consistency in end products
• Reduces material segregation and uneven melt flow
• Boosts productivity in extrusion, injection, and moulding processes
• Saves time compared to manual mixing methods
• Enables efficient use of recycled plastic materials
• Minimizes waste and quality rejection
• Enhances performance in automated production lines

Significance:

• Plays a critical role in quality control for plastic products
• Supports the circular economy by optimizing use of recyclables
• Helps meet ISO and industry-grade standards in production
• Reduces labor cost and operational errors
• Compatible with continuous or batch feeding systems
• Ideal for both large and small-scale plastic processors
• Available in various capacities from 25 kg to 5000 kg

FAQs

What materials can be mixed in a vertical mixer?
Mainly plastic granules like LDPE, HDPE, PP, PET, PVC, and regrinds.
Is it suitable for color masterbatch blending?
Yes, it ensures uniform color distribution across granules.
What are the available capacities?
From 25 kg to 5 tons, based on model and requirement.
Does it require heating?
Optional heater attachment can be used for drying or moisture control.
Is it safe to operate?
Yes, with overload protection, enclosed cover, and emergency stop.
What power source is required?
Standard models work on 3-phase AC, with varying HP based on size.
How long does mixing take?
Typically 5–15 minutes per batch depending on material type.
What is the maintenance frequency?
Regular lubrication and cleaning keep the mixer running efficiently.
Can it be used for powder mixing too?
It’s designed mainly for granules; powders may need a paddle-type mixer.
Is it suitable for automated plants?
Yes, can be integrated with hopper loaders or extruder feeders.
