• 1. Raw Material Silos:
  1. Silos for cement, fly ash, and gypsum storage, ensuring continuous supply to the production process.
• 2. Slurry Preparation Tanks:
  1. Tanks equipped to prepare fly ash slurry and pulp slurry using suitable mixing mechanisms, ensuring proper consistency and uniformity.
• 3. Slurry Holding Tanks:
  1. Tanks are designed to hold fly ash slurry and pulp slurry before they are used in the panel production process, integrated with mechanisms for controlled flow.
• 4. Water Tank:
  1. Daily-use water tank for mixing and other process needs during production.

• Facing Sheets:
  1. Sheets such as fibre cement boards or FOB (fibre-oriented boards) with dimensions of 600mm width and varying lengths (3m, 2.7m, 2.4m) and thicknesses (4mm/5mm).
• Core Materials:
  1. Fly ash, cement, gypsum, pulp, recron fibre, aluminium powder, etc., are used in varying proportions to achieve desired panel characteristics.

• Batching Plant:
  1. Facility to accurately measure and combine raw materials for the slurry and core mixtures.
• Trolleys with Dividing Frames and Clamps:
  1. Trolleys equipped with frames and clamps to hold and divide the facing sheets during the pouring process.
• Pouring Mixer:
  1. Mixer used to prepare and pour the core mixture onto the facing sheets.
• Pouring Chutes:
  1. Chutes are designed to pour the core mixture onto the facing sheets, facilitating the production of multiple panels (e.g., 20/22 panels) simultaneously.

• Panels are allowed to rest in a designated area immediately after pouring.
• After a resting period (typically a day), panels are carefully restocked and placed on cushioning items like husk bags.
• Final curing lasts three to four days before panels are ready for dispatch, with any edge damages repaired as needed.

• PLC Control:
  1. The entire manufacturing process is controlled by Programmable Logic Controllers (PLC) at the batching stage, ensuring precision and consistency.
• Weigh Hoppers:
  1. Hoppers are provided to accurately measure and dispense raw materials into the mixing process.

• Regular maintenance includes cleaning of main mixers, fly ash mixers, and pulp mixers at the end of each shift or production stoppage.
• Ongoing maintenance tasks include greasing, oiling, and addressing leaks in air, water, or slurry systems.

• Production capacity is determined based on the number of panels to be produced per day or shift, influenced by trolley and dividing frame capabilities.

• Panels are manufactured in varying thicknesses: 32mm, 50mm, and 75mm, meeting different structural and insulation requirements.

• Lightweight and Insulating:
  1. Sandwich panels offer excellent thermal and acoustic insulation properties.
• Structural Integrity:
  1. Designed to withstand structural loads while being lightweight, enhancing building efficiency.
• Versatility:
  1. Suitable for diverse applications in residential, commercial, and industrial construction.

This setup outlines a comprehensive facility designed to produce sandwich panels efficiently, integrating precise control, maintenance protocols, and a variety of materials to meet construction demands effectively.
