Perforated Metal Sheet
For many, perforated metal square hole patterns are more visually appealing than round holes, a key consideration when
the aesthetics of the product are of primary importance. Additionally,
square hole perforated metal provides a larger open area.
As
a highly-accomplished wire mesh exporter, Kingdelong was established
jointly by China and South Korea in 1986, Our strategic location in
Anping County,Hebei province is only 300KM away from Beijing and
Tianjin, which offers us very competitive advantages both in trade and
logistics. Through two decades of hard work, Kingdelong company had
evolved into one of China`s largest wire mesh manufacturing
companies,Covering an area of over 200,000㎡, certificated by ISO 9001
& ISO 14001,as well as more than 450 diversified production
machines, which are either imported from foreign countries or developed
in-house.Wire mesh products find applications in a wide range of
industries, from Pharmacy to petroleum and chemical to textile.

The potash ore is composed of several lenticular ore bodies. The thickness of the ore body ranges from a few centimeters to tens of meters, and the ore body inclination angle is 40° to 75°. The mine has always used vertical fan-shaped deep hole falling ore, and the structure of the bottom of the trench is eel. The mining method at the stage of mining. Due to the high bulk output rate, the large consumption of secondary crushing explosives and the low efficiency of mining, the vibrating miner was used instead of the electric tapping, as shown in Fig. 1. The upper and lower fan-shaped deep holes are drilled in the rock drilling roadway at the top and bottom of the mine. In order to improve the quality of the blasting, the explosive charge is filled with the chargeer, and the charge density is 1 to 1.1 g/mm 3 , so that the bulk yield is reduced by 10 to 12% from the original 15 to 25%. Due to the use of vibrating miners, the bottom structure is relatively simple. Only a trench with a horizontal plane of 15° is drilled at the bottom of the entire mine. The vibrating miner is installed at the miner's mouth where the transport lane intersects the trench roadway. Where. The пBC-300 vibrating miner is selected, which consists of 3 to 5 sections (depending on the length of the transportation distance), and is buried in the ore heap to form trough type ore to reduce ore blockage. The collected ore falls onto the vibrating miner and the ore is transported by a vibrating miner to a mine car (volume 3.4 m 3 ) parked in the transport lane. With this method, the production capacity of the mining room has been greatly improved, and the production capacity of mining and loading has reached 310-820 tons/shift.
