Plugs and shims for hard rocks (wedges and feathers)

1. Functions  

Wedge and shims is a kind of manual tools that uses manpower to impact the metal wedge into holes on stone, thereby split stone. It is mainly used in splitting cracked stone and arch stone which by utilizing a wedge set can be separated into smaller or standard stone blocks. It can also trim relative large and irregular stone blocks.

2. The Characteristics   1.) Mainly rely on manpower, therefore its labor intensive.

  2.) Suitable for exposed ore, cranny-upgrowth efflorescence ore belt, particularly for naturally formed multi-free surfaces ores, and arch stones with one or two surfaces connected with original rock. Hence, wedge is a very effective and labor-saving tool, especially for mines applying small size of quarrying stone blocks.

  3.) Suitable for mining where lack of power, water supply.   4.) Suitable for quarrying layered ores which are either horizontal or gently inclined, have layer depth around 1.5m.   5.) Can apply desegregation and separation of large stone blocks quarried through other methods.   6.) It is easy to handle with and maintains its value in mines of which have better rock fracturing performance and low mechanical level. However, the workload of leveling stone blocks is high which affect the finish rate.

3. Operating

Generally speaking, 3 sets of wedge and shim are required for per foot of length of stone. The depth of drilled hole depends on the length of wedge.

4. Specifications

Hole diameter design: 14mm to 38mm

Length: 125mm to 600mm

5. Producing technology

We produce this manual stone splitter by forgeing. It's largely prolong the life time of the tools.

Most cost-effective tools for splitting stone. The oldest and one of the best ways to split stone.Our high quality wedge and feathers are made for splitting granite and other hard stones.
