Brief Introduction Jaw crusher is a high-efficiency and energy-saving crusher designed by our company absorbing successful home and abroad experience. Large and medium jaw crushers are our competitive products and Zhengzhou General Mining Machinery has reached leading level in the design and production of large and medium jaw crushers.Jaw crusher, divided into coarse crushing and fine crushing, is applicable for medium grained of various ores and large materials whose compressive strength is under 320Mpa. And this series crushers have different models with the feed size of 125-750mm which is the first choice for primary crushing. Jaw crusher is widely used in mining, metallurgy, building material, highway, railway, water conservancy and chemistry industries. Jaw crusher is applicable for processing of river pebble, granite, basalt, iron ore, limestone, quartz, diabase, iron ore, gold, copper, etc. |
Running Environment
During the crushing procedures, crusher in the first stage is usually called as major crusher. And jaw crusher has a long history and is the most substantial crusher. When fed in jaw crusher, materials were poured into the crushing cavity from the upper inlet and the movable plate supports the materials against the cavity wall with huge forces to crush them into small patches. The movable plate is supported by a eccentric shaft through the machine frame and the eccentric movement results from the flywheel fixed at the two ends of the shaft. The flywheel and the eccentric supporting bearing usually adopt spherical roller bearing whose working environment is extremely harsh because the bearing needs to afford huge impact load, corrosive waste water and high temperature. With such tough working environment, the jaw crusher produced by Zhengzhou General Mining Machinery Co., Ltd. still can woke steadily, which we know is an important step in ensuring production efficiency.
Working Principles
Jaw crusher contains frame, eccentric shaft, big belt pulley, flywheel, side guard plate, toggle plate, back seat of toggle plate, clearance adjustable screw, reset spring, fixed jaw and movable jaw, etc. and among them the toggle plate also has insurance effect.
The crushing way of this series jaw crushers is curve extruding. The motor-driven belt and belt pulley drive the moveable jaw plate up and down through eccentric shaft. When the movable jaw plate moves up, the angle between the toggle plate and the movable jaw plate gets larger, which pushes the movable jaw plate close to the fixed jaw plate and in this procedure the materials have been squeezed, rubbed and ground; while the movable jaw plate moves down, the angle between the toggle plate and the movable jaw plate gets smaller, the movable jaw plate leaves the fixed jaw plate with forces from the pull rod and the springs and this time the ground materials will be discharged from the bottom opening of the grinding cavity. With periodic crushing and discharge of the movable plate driven by the motor, volume production is completed.
In powder grinding production lines, the input materials can not be too big so the raw materials need to be crushed by the jaw crusher before being transmitted to the mill by the elevator for processing. Besides, in stone crushing production lines and sand making production lines, the materials also need to be crushed into small pieces for further crushing and this procedure is the first crushing stage in which jaw crusher will be used often. And to chose coarse crushing machine or fine crushing machine depends on actual raw materials.
