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 the crushing ratio, even granularity, simple structure, reliable, easy maintenance, operating costs and economic characteristics. Jaw crusher is widely used in mining, metallurgy, building materials, road, 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-driven 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 to close to fixed jaw plate, while the material is squeezed, rubbing, grinding, such as multiple broken; when moving the jaw down, the elbow angle between the plate and moving jaw smaller, movable jaw plate in the bar, under the action of the spring to leave the fixed jaw board, 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 periodic discharge, to achieve mass production. When we use jaw crusher long time, there will be sealing the phenomenon, what is the best way how to deal with the following major industrial by-side for the brief introduction.
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. There are usually two cases resulting jump stop: the first one is the crusher, high output, no time taken away conveyor plate; second jump stop downstream equipment, crusher to break. This one volume occurs, the material to crushing cavity can continue to turn out all the reasons, time-consuming, generally have at least 3 to 4 hours to complete.
In order to prevent blocking material, We use sound and light indicator by way of direct instructions down material. As the crusher conveyor under the operation of heavy current and how much material under the chamber there is a good correlation, and multi-cavity each time the next jump lead to stop when the crusher, the conveyor according to the current characteristics of the plate, developed solutions that fall 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 current value, the relay, warning lights start flashing, bells are ringing. If the downstream device to stop dancing, plate conveyor current is zero, the alarm will sound and light have prompted. Tramcar driver after receiving the alarm will stop down 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 . http://www.crushertrade.com
