The granite sand is widely used for railway, highway, airport, bridge and many other fields. It has widely application in construction fields, cast metallurgy, chemical industry, and so on. Compared with other types of sand and aggregate, granite sand is considered superior to other sand in terms of thermal stability, heat and sound insulation properties, vibration resistance and durability. Here we focus on the granite sand production line in Indonesia.Granite is a hard, dense, dark volcanic rock with high hardness, and high anti-resistant.
As we all know, gold-bearing rocks are very hard, so it takes a longer time and needs more machines to deal with. After the two crushing stages, large gold-bearing rocks are crushed into small gold-bearing particles, which will be further processed by grinding mills, such as ball mills, rod mills, and vertical mills. After the crushing and grinding stages, small gold ore particles should be further processed by floatation machine, which is specially used during the benefication process. No matter which method you adopt in the process of gold mining, crushing is the primary step, to some degree, the effect of crushing can determine the quality of product. The hardness of gold ore is about 6, therefore, when crushing gold ore, it can be divided into two crushing stages, coarse crushing and secondary crushing.
Under this circumstance, under the squeezing force of jaw plates, the momentary slide of raw materials increases. But this method will cause the change of texture of jaw plates and accelerate the abrasion of jaw plates. Especially when there are many impurities in jaw plate material, under great crushing force, it may cause the fracture of jaw plates.In the operation process of pendulum jaw crusher, especially when the crushing ratio is large, the blocking of raw materials is relatively serious, leading the difficulty of crushing or even cannot crush the raw materials. After blocking, many customers adopt blasting method, which is very convenient and fast. At the same time, the abrasion of jaw plates will make the nip angle increase, which will accelerate the blocking and form vicious cycle.
Heavy mining machinery is needed in kyanite mining for exploration and development, to remove and stockpile overburden, to break and remove rocks of various hardness and toughness, to process the ore and for reclamation efforts after the mine is closed.
