How the Lubrication System Works in a Briquetting Press

A briquetting press relies on a properly maintained lubrication system to minimize friction, reduce wear, and ensure smooth operation under high-pressure conditions. The system delivers lubricant to critical components to prevent overheating and mechanical failure.

Key Components & Operation

1. Lubrication Points

   • Main Shaft & Bearings: High-load rotating parts requiring continuous lubrication.

   • Piston/Cylinder Assembly: Reduces friction during compression strokes.

   • Die & Roller Surfaces: Prevents material adhesion and wear.

   • Gearbox & Hydraulic System: Ensures efficient power transmission.

2. Types of Lubrication Systems

   • Automatic Centralized Lubrication (Most Common)

     • Uses a pump and distribution network to supply grease/oil at timed intervals.

     • Ensures consistent lubrication without manual intervention.

   • Manual Lubrication (Smaller Machines)

     • Operators apply grease via nipple fittings at scheduled intervals.

   • Oil Circulation System (High-Speed Presses)

     • Filters and recirculates oil to cool and lubricate gears/hydraulics.

3. Lubricant Selection

   • High-Temperature Grease: Withstands frictional heat (up to 150°C).

   • Synthetic Oils: Used in hydraulic systems for better thermal stability.

   • Food-Grade Lubricants: For biomass briquette presses in agro-processing.

4. How It Works

   • During operation, the system:

     1. Pumps lubricant to bearings, slides, and dies.

     2. Forms a protective film to separate metal surfaces.

     3. Dissipates heat generated by friction.

     4. Flushes out contaminants (dust, metal particles).
