Henan Mingchang mechanical equipment jaw crusher, the equipment can be used for highway, railway, stone yard, metallurgy, etc., for coarse and fine crushing of ore, river pebble, pebble, copper ore, limestone, limonite, hematite and large materials. the equipment components are composed of body shell, moving jaw plate, fixed jaw plate, driving motor and flywheel. According to the site conditions, the fixed installation of large equipment or customized support installation of small equipment can be carried out. the device makes the moving jaw move up and down through the eccentric shaft. When the moving jaw rises, the angle between the elbow plate and the moving jaw increases, so as to push the moving jaw plate close to the fixed jaw plate, and at the same time, the material is crushed or split to achieve the purpose of crushing. When the moving jaw goes down, the angle between the elbow plate and the moving jaw plate becomes smaller, and the moving jaw plate leaves the fixed jaw plate under the action of the pull rod and spring. At this time, the crushed material is broken from the broken jaw plate Lower cavity outlet. with the periodic movement of the crusher and the discharge of materials, the mass production is realized.
