The prevention of jaw crusher sealing method
Jaw crusher appeared in 1858, is widely used in road construction at first, later used in mining. With crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. Jaw Crusher is widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and many other sectors, broken no more than 320 MPa compressive strength of various materials. jaw crusher way to move music compression type, motor drive belt and pulley, the eccentric shaft to move the jaw up and down movement, when the moving jaw to rise between toggle plate and moving jaw angle becomes larger, thus promoting the moving jaw plate close to the fixed jaw plate, while the material is squeezed, rubbing , grind, such as multiple broken; when moving the jaw down, the toggle plate and moving jaw angle between, moving jaw plate rod, under the action of the spring to leave the fixed jaw plate, this time under the broken material from the crushing chamber discharge port, With the mobile jaw crusher motor for continuous rotation of the crushing and nesting periodicity, and mass when we used jaw crusher long time, there will be sealing the phenomenon, what is the best how to deal with method, following a brief introduction about.
Crusher, sealing the main reason is the jump stop under the crusher cavity in the row of the plot not too much material, to withstand the dynamic cone, resulting in motor overload jump stop, usually caused by two things jump stop: the first is broken machine output is high, no time taken away conveyor plate; The second is the downstream equipment jump stop, continue crushing crusher in which case an amount occurs, the material to crushing cavity can continue to turn out all the reasons, time-consuming, generally must be at least 3 to 4 hours to complete.
In order to prevent blocking material, directly through the sound and light indicator indicating feed down due to heavy under crusher conveyor running under the chamber current and the number of materials have good correlation, and each caused more than under the crushing chamber jump when the machine stops, so the plate conveyor according to the current characteristics, formulate a solution that is poured in the crusher discharge port install an alarm bell and flashing lights, the relay is directly connected with the electrical cabinet, when the plate conveyor to a set given current value, the relay, warning light started flashing, bells are ringing, if the downstream equipment, jump stop, slat conveyors current is zero, the alarm will sound and light have prompted. tramcar driver received alarm will stop after the fall material to prevent sealing.
Crusher for solving the issue of blocking material, can be solved, not only can reduce the labor burden, but also improve production efficiency crusher, crushing machine to make it to the normal and effective work, which reduces maintenance time, increased economic .
