Common causes and solutions for screen clogging:

• Cause 1: Material moisture too high → Check moisture before processing; add drying or conditioning if needed.
• Cause 2: Insufficient screen tension → Regularly check screen tension; loose screens cannot vibrate effectively.
• Cause 3: Excessive feed rate → Adjust feeder for uniform feeding.
• Cause 4: Worn cleaning balls → Inspect and replace rubber balls inside screen box.
• Cause 5: Incorrect screen mesh selection → Choose appropriate aperture size based on material particle size.

Daily maintenance: clean screen surfaces after each shift; weekly: check for screen damage; monthly: inspect cleaning ball condition.

Noise sources and mitigation measures:

• High-pressure fans (up to 110dB): Install silencers at outlets or house fans in separate soundproof rooms
• Air compressors and blowers: Place in dedicated soundproof rooms isolated from main workshop
• Roller mill vibration: Check roller parallelism, bearing wear, and anchor bolt tightness
• Piping systems: Check sealing at air duct connections to avoid whistling

Install sound-absorbing materials (e.g., polyester fiber panels) on interior walls, and use vibration dampers between equipment and floor. After treatment, indoor noise can be reduced to approximately 70–75dB.

We use standard packaging suitable for international sea/air freight:

• Main equipment: Secured with fumigation-free wooden crates or steel frames, wrapped with moisture-proof film
• Motors and precision components: Individually packaged with desiccants for moisture and shock protection
• Screens and wear parts: Separately boxed with clear labeling
• Control systems: Anti-static packaging with “Handle with Care” labeling

Shipping is typically by sea (full container or LCL); air freight is available for small emergency spare parts. We provide detailed packing lists, equipment lists, and customs clearance documents (commercial invoice, certificate of origin, packing list) to ensure smooth clearance at the destination port.

We offer the following installation support options:

• On-site installation guidance (recommended): Our technicians can travel to your facility to guide installation, commissioning, trial runs, and operator training. Typically requires customer to cover round-trip airfare, accommodation, and local transportation.
• Remote video guidance: For simple lines or facilities with experienced staff, real-time video guidance (WhatsApp/Skype) is available along with drawings and instructional videos.
• Local third-party installation: In some regions, we can recommend local installation service partners (additional cost).

Installation and commissioning typically take 5–15 days, depending on line scale and complexity. We recommend preparing foundations, power, water, and other infrastructure before equipment arrival.

We can customize according to your regional electrical standards:

• Voltage: 380V/415V 50Hz (suitable for most of Asia, Africa, Europe); 220V/240V 60Hz (suitable for parts of the Americas)
• Total power: Ranges from tens to hundreds of kilowatts depending on line scale; we provide detailed power consumption lists
• Control panel: Standard PLC control panel with one-touch start/stop, fault alarms, current monitoring, and other functions

We recommend completing power connection before equipment arrival, and installing voltage regulators or generators to handle fluctuations (especially in areas with unstable grid supply).

We typically offer the following payment terms:

• Standard terms: 30% advance payment (upon contract signing), 70% balance (before shipment or against copy of bill of lading)
• Letter of Credit (L/C) : Sight L/C accepted; specific terms negotiable
• Small orders: 100% prepayment (for spare parts or small items)

All payments are made through corporate bank accounts to ensure transaction security. We provide pro-forma invoices (PI) and contracts for your internal approval.
