Mining Tools
Grinding Balls
Material: Forged steel or high-chromium cast iron
Era: 20th century (Used throughout the active operation of the Sungai Lembing underground mine)
Origin: Imported from Europe/China by PCCL
Condition: Rusty and with surface erosion due to intensive use and exposure to water and minerals
Dimension: Diameter on average 20 mm to 150 mm, depending on the grinding machine type
Function: Used in ball mills or SAG mills to crush raw rock into a fine powder prior to tin ore separation
Capacity: A grinding machine typically loads hundreds of these balls simultaneously
Mining Tools
Kiew Wheel
Material: Robust cast iron with a brown protective coating.
Era: Early 20th century (1900s to 1940s).
Origin: The PCCL workshop in Sungai Lembing
Condition: The metal surface was cleaned and repainted for museum display.
Dimension: Diameter of 1.5 m
Function: The most important tool in headframe construction (Kyiv), used to lower miners, equipment, support beams, or tin ore into the depths of the mine.
Capacity: Designed to withstand the tensile force of the steel cable that transports heavy loads hundreds of meters underground.
Mining Tools
