Выбор подходящих лезвий дробилки критически важен для оптимизации процесса переработки пластика или производства. Будь вы инвестируете в новую дробилку или заменяете запасные лезвия, понимание типов лезвий, материалов и их совместимости может значительно повлиять на производительность, операционные затраты и качество выходного продукта. В этом подробном руководстве мы разбираем все, что профессионалы отрасли, покупатели и международные торговцы должны знать, чтобы сделать осознанный выбор.
Понимание типов лезвий дробилки и их применений
Лезвия дробилки не универсальны. Правильный выбор зависит от многих факторов, включая материал, который вы обрабатываете, его примеси и ваши цели производства. Ниже мы исследуем наиболее распространенные типы лезвий и их идеальные области применения.
Лезвия нарезного типа

Лезвия нарезного типа предназначены для эффективной обработки хрупких пластиков. Они преуспевают в гранулировании пластиковых листов, панелей, труб и профилей с высокой производительностью и равномерной гранулировкой. Основное преимущество - их способность обеспечивать высокую производительность с равномерной гранулировкой, делая их первым выбором для операций, ориентированных на объем и равномерность.
Лезвия плоского типа


Для обработки пустотелых или тонкостенных пластиковых изделий, таких как пластиковые коробки, бутылки, вспененные материалы и трубы толщиной менее 3 мм, лезвия плоского типа являются вашим выбором. Их широкая структура поддерживает высокую пропускную способность и снижает риск закручивания материала вокруг лезвия, обеспечивая плавное, непрерывное функционирование.
Лезвия V-образного типа

При работе с гибкими, мягкими пластиками, такими как пленки, пакеты или волокнистые материалы (например, пакеты PP в огромных размерах, пленки PE), лезвия V-образного типа предотвращают засорение и обеспечивают постоянное резание. Их дизайн позволяет обрабатывать материалы с высокой эластичностью без засорения, что критично для поддержания бесперебойной работы линий переработки пленок и пакетов.
Claw Blades

For tackling hard and thick plastics, including solid blocks, rods, or engineering plastics, claw blades are indispensable. They are designed to withstand high-stress conditions, ensuring minimal wear and offering cost-effectiveness for demanding applications.
Choosing the Right Blade Material
The selection of blade material significantly impacts its lifespan, maintenance requirements, and wear resistance. This decision should be based on the cleanliness of the plastic material and the presence of contaminants, such as metals.
| Material | Best For | Relative Lifespan |
|---|---|---|
| Spring Steel | Materials with metal impurities | Base reference (1x) |
| Tool Steel (e.g., 55-SiCr) | Moderately clean plastics | Tritium Spring Steel |
| Tool Steel (e.g., SKD-11, D2) | Free of contaminants, pure materials | 5-6x Spring Steel |

If your input material includes screws, nails, or other metallic debris, consider cost-effective options like spring steel to minimize replacement expenses. For cleaner plastics, invest in high-alloy steels like SKD-11 or D2 for an extended operational lifespan and reduced downtime.
Mechanism of Blades in the Crushing Chamber
In a typical plastic crusher, the crushing chamber is equipped with both fixed and rotating blades. The material enters through the inlet, where the spinning rotor's blades interact with the stationary ones, cutting the plastic into smaller pieces. These pieces are then sieved through a screen, completing the size reduction process. Selecting the right blade type ensures this process is efficient, reducing energy consumption and wear on other components.

Critical Aspects of Blade Selection for the Crusher
Состав материала
The type of plastic—whether it's soft, brittle, thick, or contaminated—determines the blade's shape and material. Always match the blade to the material's physical properties.
Equipment Output Capacity
The frequency of replacing crusher blades depends on several factors including the volume of material being processed, the hardness and type of the material, and the operational conditions. Typically, blades may need to be replaced every 1,000 to 5,000 hours of operation, but this can vary widely. Regular maintenance checks and monitoring the condition of the blades can help predict when a replacement might be necessary, ensuring optimal performance and minimizing downtime.
Blade Geometry
The shape influences cutting efficiency and material flow. Consider factors like blade angle, thickness, and hardness based on operational demands.
Output Requirements:
Whether you need coarse fragments or fine granules will determine the blade’s tooth design and the screen size used in conjunction.
Alloy Quality
Invest in blades from reputable manufacturers like Rumtoo Machine to guarantee material integrity, heat treatment, and overall durability. Inferior blades lead to increased downtime and higher long-term costs.
Operational Longevity
Choose blades that offer the best balance between initial cost and service life. Sometimes, a higher upfront investment in premium materials pays off through reduced maintenance and replacement频率.
Preguntas Frecuentes (FAQ)
Q: How often should crusher blades be replaced?
A: Replacement frequency is determined by usage, material abrasiveness, and blade material. Die steel blades can endure 5-6 times longer than spring steel under comparable conditions.
Q: Can a single blade type process multiple materials?
A: Although some blades are adaptable, it's advisable to use specialized blades for different materials to maximize efficiency and extend blade lifespan.
Q: What maintenance is required for crusher blades?
A: Regular inspection for sharpness, damage, and alignment is essential. Keep blades clean and sharpen or replace them as needed to maintain optimal performance.
Q: How do I know if my blades need sharpening?
A: Reduced output, uneven granulation, or increased power consumption are typical indicators that blades require attention.
