Digital control system for precise operation
Modular components for easy maintenance and replacement
Built-in safety shields and emergency stop systems
Rotary tablet presses come in a variety of specifications to accommodate different production needs. The table below summarizes typical models and specifications:
Model | Turret Stations | Max Compression Force | Tablet Diameter Range | Tablet Thickness | Max Filling Depth | Production Capacity | Motor Power | Weight |
---|---|---|---|---|---|---|---|---|
ZP30-17 | 17 | 30 kN | 5–20 mm | 2–6 mm | 12 mm | 5,000–15,000 tablets/hr | 3 kW | 950 kg |
ZP50-11 | 11 | 50 kN | 6–25 mm | 2–8 mm | 15 mm | 10,000–30,000 tablets/hr | 4 kW | 1,200 kg |
ZP80-10 | 10 | 80 kN | 8–25 mm | 3–8 mm | 15 mm | 15,000–50,000 tablets/hr | 5–7 kW | 2,000 kg |
Note: Specifications may vary depending on manufacturer and production requirements.
Operating a rotary tablet press safely is essential to prevent accidents, machine damage, and production errors. Key precautions include:
Inspect the machine for wear, damage, or misalignment
Ensure all safety shields and emergency stop systems are functional
Clean the hopper, punches, and dies
Confirm that lubrication systems are filled and operational
Load powders or granules into the hopper evenly
Avoid overfilling, which may cause blockages or uneven compression
Ensure consistent material flow using the feeder system
Turn on the machine using the digital control panel
Adjust pressure, turret speed, and fill depth according to tablet specifications
Monitor initial batches to ensure uniform tablet weight, thickness, and hardness
Use the emergency stop in case of abnormal conditions
Wear personal protective equipment (PPE), including gloves, goggles, and masks
Never place hands near moving punches or dies
Follow lockout/tagout procedures during maintenance or cleaning
Modern rotary tablet presses are designed to be energy-efficient, reducing operational costs without compromising production quality. Key features include:
Optimized motor systems that consume less electricity during high-speed operation
Variable frequency drives (VFDs) for precise speed control
Low-friction turret and roller designs to minimize energy loss
Reduced downtime due to modular and easy-to-maintain components
Energy-efficient operation helps manufacturers save on electricity bills and supports sustainable production practices in pharmaceutical manufacturing.
Common issues in rotary tablet presses can affect tablet quality and machine performance. Practical solutions include:
Problem | Possible Cause | Solution |
---|---|---|
Uneven tablet weight | Improper fill depth or powder inconsistency | Adjust filling system, check powder flow |
Cracked tablets | Excessive compression pressure | Reduce pressure, check punch alignment |
Tablet sticking | High moisture content or inadequate lubrication | Dry powder, clean and lubricate punches |
Machine vibration | Loose components or uneven base | Tighten bolts, level machine base |
Reduced output | Worn punches/dies | Replace punches or dies, check turret alignment |
Regular preventive maintenance can prevent most issues and maintain consistent production quality.
Maintaining a rotary tablet press ensures long-term efficiency and safety:
Clean powder-contact surfaces after each batch
Inspect punches and dies for wear and replace as needed
Lubricate moving parts according to manufacturer guidelines
Check hydraulic and electrical systems for proper function
Document maintenance and repairs for quality control compliance
