【Product Overview】

The grain suction machine special rubber hose is a core supporting hose for grain negative pressure conveying scenarios, specially developed for the negative pressure suction working conditions of grain suction machines. It solves common pain points of ordinary hoses such as easy collapse, grain adhesion and blockage, static risks, fast wear and grain contamination. Formed by multi-layer composite vulcanization process, the layers are tightly bonded without delamination, bulging or cracking during long-term use. The hose combines negative pressure resistance rigidity and flexibility, adapting to the high-frequency conveying operations of grain suction machines while meeting the food-grade safety requirements for grain conveying, widely used in agriculture, grain storage and processing fields.

【Product Structure & Core Materials】

1. Inner Rubber Layer: Made of food-grade natural rubber/special rubber formula, with smooth inner wall to prevent grain adhesion, no contamination to grain color and flavor, meeting food contact rubber product safety standards, resistant to grain particle scouring and corrosion.
2. Reinforcement Layer: High-strength polyester cord braided/wound layer, improving the hose’s tensile and burst resistance, preventing bursting during high-pressure conveying or extrusion, and extending service life.
3. Spiral Steel Wire Skeleton: Built-in metal spiral steel wire, effectively resisting the negative pressure suction of grain suction machines, no collapse or deformation during long-term conveying, ensuring smooth and uninterrupted conveying.
4. Outer Rubber Layer: Weather-resistant and wear-resistant rubber material, anti-aging, anti-UV and anti-ozone, adapting to complex operating environments such as outdoors and warehouses, not easy to crack or harden.
5. Specifications & Customization: Conventional inner diameter range DN50~DN200 (customizable non-standard large caliber), length can be cut according to equipment model and conveying distance, adapting to various imported/domestic grain suction machines and grain conveyor equipment.

【Core Performance Advantages】

1. Negative Pressure Collapse Resistant, Stable Conveying: Built-in spiral steel wire skeleton, can withstand the negative pressure working conditions of grain suction machines, no collapse or flat pipe during long-term conveying, avoiding conveying interruption or grain blockage.
2. Anti-static & Explosion-proof, Safe and Reliable: Built-in conductive structure, can discharge static electricity generated during grain conveying, eliminating the risk of grain dust explosion, meeting the safety standards of the grain processing industry.
3. High Wear Resistance & Anti-scouring, Longer Service Life: Special wear-resistant rubber formula, inner wall resistant to long-term scouring and wear by grain particles, not easy to wear through or puncture, greatly reducing replacement frequency and usage cost.
4. Food-grade Safety, No Grain Contamination: Made of food-grade rubber material, non-toxic and odorless, no harmful substances precipitated, not affecting the color, flavor and quality of grains, meeting food contact safety requirements.
5. Smooth Inner Wall Without Grain Adhesion, High Conveying Efficiency: Smooth inner wall without burrs, grain particles flow smoothly without residue or blockage, improving conveying efficiency and reducing grain loss.
6. Flexible & Easy to Install, Convenient Operation: Good flexibility, can be easily bent to adapt to complex site layouts, no special tools required, convenient installation, movement and storage, adapting to changeable working scenarios such as farms and grain depots.
7. Complete Specifications & Customization: Sufficient stock of conventional models, supporting customized non-standard caliber, length and color, can provide personalized solutions according to customer equipment models and working condition needs.
