Pneumatic Picks

Pneumatic picks, also known as pneumatic hammers or air hammers, are handheld tools used for breaking rocks and concrete. They operate using compressed air as their power source.

Definition and Function

Pneumatic picks are pneumatic tools that use compressed air to create impact force, allowing them to break rocks and concrete. They are commonly used in mining operations for tasks such as rock excavation and demolition.

Components and Working Principle

Pneumatic picks consist of several components, including:

• Air compressor: This device compresses air and supplies it to the pick.
• Pick head: The striking element of the pick, which delivers impact force.
• Handle: The part of the pick that the operator holds.
• Trigger: The control mechanism that activates the pick.

The working principle of a pneumatic pick involves the following steps:

1. The air compressor compresses air and stores it in a tank.
2. When the trigger is pressed, the compressed air is released, creating impact force.
3. The impact force is transferred to the pick head, allowing it to break rocks and concrete.

Types of Pneumatic Picks
