Vacuum Conveyor FAQs
Q1: What types of materials can the ZKS vacuum conveyor handle?
A: The ZKS series is designed for powdery materials, granular materials, and mixed powdery-granular materials. Common examples: pharmaceutical powders, food ingredients, chemical powders, plastic pellets, and fine granules. It can convey directly into V-type mixers, 2D/3D mixers, packaging machines, and crushers.
Q2: How does the filter cleaning system work?
A: The system includes a compressed air back-blowing device. During operation, short bursts of compressed air (0.4-0.6 MPa) are fired backward through the filter, blasting accumulated dust off the filter surface. This automatic cleaning cycle maintains consistent suction performance without stopping the conveying operation.
Q3: Can the system be used for multiple pickup or discharge points?
A: Yes. The system supports long-distance operations where materials concentrated at multiple points are conveyed to a single location, or materials from one location are distributed to multiple points. This flexibility optimizes factory production process flow.
Q4: Is the vacuum pump oil-free and water-free?
A: Yes. The standard configuration uses an oil-free and water-free vacuum pump — no lubricants or seal water enters the conveying path. This prevents contamination of your materials and is essential for pharmaceutical and food GMP compliance.
Q5: How does this system help with GMP certification?
A: The fully enclosed dust-free design eliminates dust overflow during feeding. All contact parts can be made of SS304/SS316L stainless steel with smooth surfaces for easy cleaning. The system reduces manual handling, prevents cross-contamination, and promotes standardized workshop operations — all key requirements for pharmaceutical and food GMP certification.
