플라스틱 분쇄기 vs 분쇄기: 차이점과 업계에서의 최적 활용법 공개

In the world of plastic recycling and processing, size reduction is a critical first step. However, the terminology can sometimes be confusing. Two key pieces of equipment often discussed are 플라스틱 분쇄기 그리고 Plastic Grinders (also known as pulverisers or micronisers). While both reduce the size of plastic materials, they operate differently, produce distinct outputs, and are suited for varied industrial applications.

At Energycle, we understand the importance of selecting the right machinery for optimal efficiency and end-product quality. This article will delve into the specifics of plastic granulators and grinders, helping you, our valued industrial recycling equipment buyers, engineers, and sector professionals, make informed decisions.

플라스틱 분쇄기란 무엇인가요?

에이 플라스틱 분쇄기 is a robust machine designed to break down larger plastic items – such as rejected parts, sprues, runners, bottles, profiles, and films – into smaller, relatively uniform pieces called “regrind” or “flakes.”

작동 원리:
Plastic granulators typically employ a set of rotating knives mounted on an open rotor that work against stationary bed knives within a cutting chamber. As plastic material is fed into the chamber, these knives shear and cut it. A screen with specific hole sizes is situated beneath the cutting chamber, determining the final size of the granulated particles. Material remains in the chamber until it is small enough to pass through this screen.

Output Characteristics:

• Particle Size: Typically ranges from 3mm to 12mm, depending on the screen size.
• Particle Shape: Irregular, chip-like, or flake-like.
• 일률: Reasonably uniform, suitable for many reprocessing applications.

일반적인 응용 프로그램:

• In-house recycling of production scrap in injection moulding, blow moulding, and extrusion facilities.
• Pre-processing for washing lines.
• Creating regrind to be mixed with virgin material for new product manufacturing.
• Volume reduction for easier handling, storage, and transportation.

What is a Plastic Grinder (Pulveriser/Microniser)?

에이 Plastic Grinder, more accurately termed a pulveriser or microniser in many industrial contexts, is engineered to reduce plastic materials (often already pre-granulated) into very fine powders.

작동 원리:
Plastic grinders, particularly micronising systems, operate on principles of impact, attrition, or a combination.

• Disc Mill Pulverisers: These often use one or two high-speed rotating serrated or toothed discs. Material fed between the discs (or between a rotating and a stationary disc) is ground down by impact and attrition forces. The particle size is controlled by the gap between the discs, the disc design, and often an air classification system that separates finer particles from coarser ones, returning the latter for further grinding.
• Cryogenic Grinding: For some tough or elastic plastics, cryogenic grinding is employed. The material is cooled with liquid nitrogen to make it brittle before being fed into the grinder, allowing for easier pulverisation into fine powder.

Output Characteristics:

• Particle Size: Very fine, typically less than 1mm, often measured in mesh or microns (e.g., 300-800 microns or 35-100 mesh).
• Particle Shape: Fine, powder-like.
• 일률: Can be very uniform, especially with advanced classification systems.

일반적인 응용 프로그램:

• Producing powders for rotomoulding.
• Creating additives or fillers for compounding.
• Manufacturing masterbatches.
• Applications requiring high surface area, such as in certain coating processes.
• PVC pulverisation for pipe and profile compounds.

Plastic Granulator vs. Grinder: Key Differences at a Glance

Understanding these distinctions is crucial for selecting the appropriate equipment:

특징	플라스틱 분쇄기	Plastic Grinder (Pulveriser/Microniser)
주요 기능	Size reduction to flakes/regrind	Size reduction to fine powder
Output Particle Size	Approx. 3mm – 12mm (chips/flakes)	Typically < 1mm (often 300-800 microns/powder)
기구	Cutting/Shearing (knives)	Impact, Attrition (discs, hammers, etc.)
Input Material	Larger plastic parts, scrap, rejects, film	Often pre-granulated material, smaller pieces
처리량	Generally higher for a given motor size	Generally lower, more energy-intensive
에너지 소비	보통의	Higher due to finer particle size requirement
Typical Use Case	Creating regrind for reuse, pre-processing	Producing powders for rotomoulding, compounding
Downstream Process	Extrusion, injection moulding, washing, grinding	Rotomoulding, compounding, masterbatch production

Best Uses in Industry: Making the Right Choice

Choose a Plastic Granulator when:

• You need to process bulky plastic waste, production scrap, or rejected parts into a manageable size for reuse or further processing.
• The end goal is to produce regrind that can be directly fed back into extrusion or moulding machines.
• You are preparing material for a washing line where uniform flakes are preferred.
• Volume reduction for storage or transport is a primary concern.
• Your material is suitable for knife-based cutting (most common thermoplastics).

Choose a Plastic Grinder (Pulveriser/Microniser) when:

• Your final product requires a fine, consistent plastic powder (e.g., for rotomoulding, powder coatings, or specific compounding applications).
• You are processing pre-granulated material to achieve a much finer particle size.
• The material properties or end-application demand a powder form (e.g., PVC for certain pipe formulations).
• You need to achieve specific flow characteristics or surface area properties only attainable with fine powders.

Can Granulators and Grinders Work Together? The Synergistic Approach

Absolutely! In many comprehensive plastic recycling operations, granulators and grinders work in sequence.

1. Shredder (Optional): For very large or tough materials, a shredder might be used for initial, coarse size reduction.
2. Plastic Granulator: The shredded or larger plastic waste is then fed into a granulator to produce uniform flakes.
3. Plastic Grinder (Pulveriser): These flakes are then fed into a grinder/pulveriser to achieve the final desired fine powder consistency.

This multi-stage approach optimises the efficiency of each machine and ensures the desired end-product quality.
