Nowadays,as population increasing in the middle east,people need lotsd of buildings to be their new home,so middle east becomes to a very hot market about crushing process machines.
Not only government cooperate,Chinese companys have lots of cooperate with the local market of middle east such as Dubai and Turkey.
As the biggest mining machine manufacturer of China,KLD owns great reputation because of its good quality and best after serice.
In operation, the raw material (of various sizes) is usually delivered to the primary crusher's hopper by dump trucks, excavators or wheeled front-end loaders. A feeder device such as an apron feeder, conveyor or vibrating grid controls the rate at which this material enters the crusher, and often contains a preliminary screening device which allows smaller material to bypass the crusher itself, thus improving efficiency. Primary crushing reduces the large pieces to a size which can be handled by the downstream machinery.
Some crushers are mobile and can crush rocks as large as 60 inches. Primarily used in-pit at the mine face these units are able to move with the large infeed machines (mainly shovels) to increase the tonnage produced. In a mobile road operation, these crushed rocks are directly combined with concrete and asphalt which are then deposited on to a road surface. This removes the need for hauling oversized material to a stationary crusher and then back to the road surface.
The following parameter about KLD cruchers.

|---|---|---|---|---|---|
| Vertical shaft impactors (shoe and anvil) | Medium hard to very hard | Slightly abrasive | Dry or wet, not sticky | 6/1 to 8/1 | Sand & gravel, recycling |
| Vertical shaft impactors (autogenous) | Soft to very hard | No limit | Dry or wet, not sticky | 2/1 to 5/1 | Quarried materials, sand & gravel |
| Mineral sizers | Hard to soft | Abrasive | Dry or wet and sticky | 2/1 to 5/1 | Heavy mining |
| Jaw crushers | Soft to very hard | No limit | Dry to slightly wet, not sticky | 3/1 to 5/1 | Heavy mining, Quarried materials, sand & gravel, recycling |
| Horizontal shaft impactors | Soft to medium hard | Slightly abrasive | Dry or wet, not sticky | 10/1 to 25/1 | Quarried materials, sand & gravel, recycling |
| Gyratory crushers | Soft to very hard | Abrasive | Dry to slightly wet, not sticky | 4/1 to 7/1 | Heavy mining, Quarried materials |
