Medium-grained jaw crusher (referred to as the cracker) is mainly used for a variety of ores and bulk materials crushing, crushing compression strength not more than 320Mpa materials, sub-coarse and fine broken two kinds. PE series jaw crusher specification is complete, the feed particle size of 125mm ~ 1200mm, the device of choice for primary crushing. Jaw crusher (Jaw Crusher) widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical and other industries. Medium-sized jaw crusher is one of the leading products of the company, especially in the design and production of large jaw crusher, at the absolute leading level at home and abroad. Performance characteristics. Deep cavity set and no dead zone, increased capacity and output feed; 2. Crushing ratio, uniform particle size; 3. Gasket-discharge opening adjustment device, reliable and convenient adjustment range, an increase of flexibility of the equipment; 4. lubrication system is safe and reliable, easy to replace parts, maintenance workload is small; 5. reasonably simple structure, reliable operation, low operating costs; 6. equipment more energy efficient: stand-alone energy-saving 15% to 30%, the system energy efficiency more than doubled; 7. discharge opening adjustment range, to meet the requirements of different users; 8 low noise, less dust. The work of the working principle of jaw crusher motor drive belt and pulley, through the eccentric shaft to make the movable jaw up and down movement, when the movable jaw rises larger angle between toggle plate and moving jaw, thus promoting the movable jaw plate close to the fixed jaw plate, At the same time the material is squeezed, rubbing, grinding, such as multiple broken; When the movable jaw down, the angle between toggle plate and moving jaw smaller, movable jaw plate lever spring to leave the fixed jaw plate, has been crushed the material under the action of gravity through the spout of the lower portion of the jaw cavity free unloading. Thus jaw crusher work is intermittent, crushing and unloading process in the jaw cavity alternately. With the motor continuously rotating crusher mobile jaw crushing and nesting periodicity, and mass production.
