Shanghai Long Jing heavy machinery Co., LTD1.Jaw crusherThis series of crusher is mainly used for rough and moderate broken operations ofvarious ore materials those compressive resistance is not more than 320 MPa. Thiscrusher has features of high broken ratio, uniform product size, simple structure, reliableoperation, convenient maintenance, low operating costs etc, which is widely used inmining, smelting, building, roads, railways, water conservancy and chemical industry.Working principle: motor drives the eccentric axis rotating through the belt pulley, so thatthe movable jaw approaches and leaves the fixed jaw cyclically, which makes thematerials multi-crushed, such as squeezed, rubbed, rolled etc. so that the materials arecrushed into small size, and then fall below gradually, at last discharge from thedischarging mouth.
2.Impact crusherThis series of crusher can deal with various ore materials (granite, limestone, basalt,etc.), whose particle size is not more than 500mm and the compressive resistance is notmore than 350 MPa. These crushers have features of high broken ratio, high efficiency,energy-saving, convenient maintenance etc. The crushed materials are cube shaped,and the size of discharging is adjustable, so this kind of crusher is widely used inhydropower, highways, railways, artificial gravel, construction and other industries.Working Principle: The rotor rotates in high speed driven by the motor, and the materialsare impacted with the blow bar on the rotor, and then impacted with the liner plate again,and finally discharged from the discharging mouth.
3.Vertical shaft impact crusherThis series of crusher is international advanced equipment with low-energy consumptionwhich is development by our experts through drawing advanced technology from BarmacCompany of the U.S. This crusher has features of stable and reliable working, convenientmaintenance, high broken ratio, crushed materials are cube shaped, especially suitablefor the production of machine-made sand, stone shaping, and can be used in finecrushing operations of a variety of ores and non-ore.Working principle: materials fall from the upper part of the machine vertically into thehigh-speed rotating impeller. Under the high-speed centrifugal force, they collide andcrush in high speed with the other materials which distribute around the impeller like anumbrella. After the collision with each other, the materials will format a vortex betweenthe impeller and the shell, so that they will grind owing to the mutual impact and friction inmany times. At last discharge from the lower part directly, and format a many-times-closed-circuit cycle. The finished products can be control by the screening equipment toreach the required size.
4.Cone crusherThis series of crusher is a modern high-performance crusher with high pendulumfrequency, optimized cavity and a reasonable stroke, which is based on the introductionand absorption from foreign technology, according to the needs of the customer, andbased on the principle of pyramid and the conceptual of more breaking less grinding.It has features of high-performance, product composition of a good size, good stabilityand space easy clearance, convenient maintenance, easy operation etc. This crusher iswidely used in metal and non-metallic minerals, cement plant, construction, gravel andmetallurgical industries.
