Jaw Crusher features and types of work

In mining, building materials and infrastructure sectors is mainly used for coarse crushing machine and the broken machine. According to the material and width of size, into large, medium and small three, to more than 600MM width entrance and exit for large jaw crusher machine, to the entrance and exit width of 300-600MM for medium-sized jaw crusher machine Feeding and width of less than 300MM for small crusher.
    Jaw Crusher is partly the work of two jaw plates, one fixed jaw plate (fixed jaw), vertical (or the top of the slightly extrovert) fixed to the body before the wall, the other activities of the jaw plate (moving jaw), location tilt, and the fixed jaw plate formed on the large cavity under the small broken (working space). Activities against the fixed jaw plate jaw plate so cyclical reciprocating motion, sometimes separately, sometimes close. Separately, the material into the crushing chamber, finished unloading from the bottom; close, so that jaw plate mounted between the two materials by extrusion, bending and splitting the role of fragmentation.
     Jaw crusher in accordance with the activities of the swing plate in different ways, can be divided into simple swing Crusher (Crusher simple pendulum). Swing crusher complex (compound pendulum crusher) and three types of integrated swing crusher.
Jaw Crusher Working Principle:
    Jaw hanging heart axis, can be used for side to side, eccentric rotation, the rod up and down reciprocating motion. Two thrust plates driven reciprocating motion, thus promoting the jaw reciprocating motion to do so, to achieve break and discharge. Such crushing machine double crank link mechanism, although the moving jaw broken by a great reaction force, while the eccentric shaft and connecting rod are Shouli Bu large, the industry made more than mainframe and mid-sized machine, used to crushing hard materials. In addition, the work of this crusher, jaw trajectory of every point is a heart-centered arc axis, radius equal to the distance of the point to the axis, top of the arc is small, the bottom arc large broken less efficient, its broken than i usually 3-6. As the trajectory is simple, so simple, said swing jaw crusher.
1 Jaw Crusher Advantages:
    Compact and simple, eccentric drive shaft and other smaller pieces by force; as little vertical displacement fixed jaw and processing of materials have less time over the phenomenon of fragmentation, jaw jaw plate wear smaller.
Jaw Crusher Working Principle:
     Upper jaw hanging in the eccentric shaft directly, as a connecting rod connecting rod, eccentric by the eccentric shaft direct drive, moving the bottom jaw thrust plate support hinge attached to the rack in the back wall. When the eccentric shaft rotates, the movable jaw on the trajectory of each point is the circle line from the suspension point (the radius is equal to the eccentricity), and gradually down into the Oval, the more down to the Department, the more partial oval until the bottom and thrust plate connection point for the arc line trajectory. Because of this mechanical moving jaw at various points in the trajectory of complex, so called complex swing jaw crusher.
    Tilting tilting complex compared with the simple, the advantages are: quality of light, fewer components, more compact structure, degree of crushing cavity was filled with good material pieces are evenly loaded broken jaw to the bottom of the mandatory introduction of product discharge, therefore higher productivity, with the specifications than the simple pendulum jaw crusher 20-30% higher productivity; material block in the lower jaw moving up and down rolling movement with large, easy cube shape was discharged, to reduce Tilting of the products as simple as a sheet components, better product quality.
Other types of jaw crusher:
A hydraulic crusher.
2. No grinding crusher
3. Impact Crusher
4 direct Jaw Crusher
5. Lumen Crusher
6. Wedge roller crusher
Jaw Crusher main components:
1. Rack
     Up and down the walls of the opening frame is rigid framework for supporting the eccentric shaft and bear fragmentation reaction materials, require sufficient strength and stiffness, usually with the whole cast steel, cast iron minicomputers can also be used instead of high-quality steel. Sub-rack mainframe be cast, and then bolt firmly linked into the overall, complex casting process. Made a small jaw crusher frame welded thick steel plate can also be used, but less stiffness.
2. Jaw Crusher jaw plate and side plate protection
     Fixed jaw and movable jaw by the jaw and the jaw plates bed, regardless of jaw plates is working with the wedge bolt and fixed to the jaw on the bed. Jaw jaw is fixed rack anterior bed, moving bed jaw jaw hanging Week, to have sufficient strength and rigidity to withstand the crushing counter-force, so most of steel or cast iron.
3. Jaw Crusher transmission parts
Eccentric shaft is broken machine spindle, torque curve by a huge, high carbon steel. Eccentric part of the required finishing, heat treatment, the bearing liner with Babbitt pouring. Eccentric shaft pulley mounted at one end, other end of the flywheel installed.
4. Jaw Crusher conditioning
     Conditioning installations wedge, plate type and the hydraulic type, and so, generally wedge, wedge formed by the front two, the former wedge can move easily withstand push back plate; wedge after the wedge for the adjustment can be up and down Mobile, two backward fitting wedge ramp, wedge, after the screw to move up or down to adjust the size of the discharge port. Small jaw crusher discharge port after the change in regulation is the use of thrust plate bearings and gasket between the frame number to achieve.
5. Jaw Crusher Flywheel
     Jaw crusher jaw flywheel to store energy when the air travel, and then used for industrial form, so that mechanical work is in line uniformly. Also plays a role in the flywheel pulley. Cast iron or cast steel wheel manufacturing often, the minicomputer often made integral flywheel. Flywheel manufacture, installation, pay attention to static balance.
6. Jaw Crusher Lubrication Device
     Eccentric shaft bearing lubrication cycle usually concentrated. Spindle and thrust plate bearing surface generally use the grease gun oil to the oil by hand. Jaw of the swing angle is small, so that between the spindle and bearing lubrication difficulties, often open a number of axial bearing oil groove bottom, the middle part of the tank open so connected, and then forced into the dry butter oil pump lubrication.
