Americans EW dark designed and produced the original belt conveyor manufacturers through the world, using the framework of double toggle plate(simple swing). using the benefit of very simple structure, very simple manufacture,reliable, very simple maintenance, small sizing and height, these times they are even now broadly utilized to crush all sorts of hard, method hard, gentle ore and different materials,such as different minerals, solvents, slag, constructing stone, marble etc.The operating theory of YIFAN Jaw Crusher is: the engine transmits energy by making use of belt, drives the shifting jaw to hold out periodic movement in the direction of the repaired jaw in the eccentric shaft. The angle in between toggle plate and shifting jaw plate raises when shifting jaw moves. So the shifting jaw moves in the direction of the repaired jaw. The stuff will possibly be crushed on this process. The angle in between toggle plate and shifting jaw decreases when shifting jaw moves down, the shifting jaw moves leaves repaired jaw by pulling rod and spring, the last crushed stuff will possibly be discharged through the outlet.Until 1980s, the feed sizing of huge Belt Conveyor using the potential of 800TPH has reached to 1800 mm. generally jaw crushers are divided into one and double toggle plates models. The movable jaw plate inside the past just one only could make very simple arc swing when works, it may be acknowledged as very simple swing jaw crusher; the latter also do up and reducing movement in add-on to arc movement, which can be acknowledged as advanced swing jaw crusher.YIFAN Heavy Machinery Co.,Ltd. is acknowledged getting a key and pioneering business with probably the most excellent intercontinental level in R&D, production and buying and selling of large-scale crushing& screening facilities and commercial milling equipments. We have been a key producer of jaw crushers and JC sequence Stationary Crusher manufacturer for much more than twenty years.We are ordinarily insisting on intercontinental excellent specialized cooperation and communication, and introduce excellent engineering from Germany, Swedish, Finland, and make digestion and absorption to improve our products' superb continuously.
