Jaw Crusher In Nigeria

SBM is a high-tech enterprise, involved in research and development, production, sales and service as well. In the past 20 years, we are committed to the production of mining equipment, sand making equipment, industrial mill, provide highway, rail way and water conservancy engineering sand to make high-grade equipment and related solutions.

Jaw Crusher In Nigeria

Brief History

The first form of crusher is BC two thousand years appears the most simple grinding tool--a mortar and pestle. After thousands of years evolution and development, now we use high efficiency crusher, which greatly improving the crushing effect. Jaw crusher is designed by American E.W. Black (Black) in 1858, which is the first jaw crusher in the world, in the beginning it is widely used in road engineering and then used in mining process in Nigeria.

Structure Analysis

the frame

The frame is a rigid frame on the walls of an eccentric shaft, used as a support and under the crushing materials reaction which has sufficient strength and rigidity. The general casting steel, minicomputers usable also use quality cast iron substitute for casting. Made a small jaw crusher can also be thick steel plates welded together, but the stiffness is low in Nigeria.

jaw plate

Fixed jaw and a movable jaw are composed of jaw bed and jaw plate, jaw plate is not divided, bolts and wedge iron fixed in the jaw bed. Fixed jaw jaw bed is a front wall, a moving jaw bed hanging in the week, must have sufficient strength and stiffness, to withstand the crushing force, which are mostly cast steel or cast iron.

driving medium

The eccentric shaft axis crusher, the bending torsion giant, adopting high carbon steel. Eccentric part must finish machining, heat treatment, bearing with Babbitt pouring. The eccentric shaft is a belt wheel, the other end is arranged flywheel.

Product Application

PE Jaw Crusher through independent research and development and design of our company,keeps leading position in the production of large jaw crusher in Nigeria. SBM PE Jaw Crusher commonly used in mining, metallurgy, building materials,road,water,chemicals and a variety of ores,and many other industries. In most cases, it is suitable for material primary crushing.

Product Advantage

  • The application of world-class manufacturing processes and high-tech materials.
  • The crushing chamber uses "V"-shaped structure, so that the feeding size equal to the nominal one.
  • Simple structure, easy maintenance;Stable performance, high capacity.
  • Lubrication system is safe and reliable, convenient to replace parts, easy to maintain.
  • The outlet employs shim adjustment system, convenient and reliable, and increase the flexibility of the equipment.
  • Integrated steel structures are used for the base of bearing.

Operational Principle

PE jaw crusher uses the electric motor as power, through the eccentric shaft the motor pulley, V-belt and pulley driven, the movable jaw according to a predetermined track reciprocating motion, thus will be broken into by the crushing cavity fixed jaw plate, the movable jaw plate and the side plate is composed of material, and through the discharge port in the lower part of the finished product discharging material in Nigeria. This series of jaw crusher is curved extrusion, motor drive belt and pulley, the eccentric shaft to make the moving jaw moves up and down, when the movable jaw rises toggle and jaw angle become larger, which pushes the movable jaw plate close to the fixed jaw plate, at the same time the material is extruded, rubbing, run multiple broken; when the movable jaw down, elbow board and the movable jaw angle become smaller, the movable jaw plate away from the fixed jaw plates in bar, under the action of the spring, this time has been broken materials discharged from the crushing cavity opening, with the continuous rotation of the motor broken jaw as crushing periodic and discharging to achieve mass production.
