Jaw crusher can be broken on a variety of ore and large pieces of material, jaw crusher is mainly used for mining, smelting and building materials, chemical and other industries.

working principle

Jaw crusher motor driven belt and pulley, move the jaw up and down, move the jaw up when the bracket and moving jaw angle between the larger, to move the jaw to the fixed jaw close to the same time, the material in the extrusion was Crushing or splitting, so that the material broken; when the moving jaw down, the elbow plate and the moving jaw angle between the large and small, moving jaw plate under the action of the spring and pull the bar away from the fixed jaw plate, the broken material from the bottom discharge.

Features

Jaw crusher and crusher compared with the crusher than the large, energy-saving equipment, stand-alone can save energy consumption of 15% to 30%, can make the system more than double energy, this device can adjust the range to meet the different User demand, equipment, low noise, the production process of less dust.

Jaw crusher system components

Jaw crusher system components

Jaw crusher is a mechanical equipment broken materials, machinery production line is commonly used in one of the equipment, widely used in mining, smelting, building materials, roads, railways, water conservancy and chemical industries in a variety of minerals and bulk materials broken.

1. Rack

Rack is the upper and lower openings of the four-wall rigid frame, used to support the eccentric shaft and withstand the reaction of broken material, requires a sufficient strength and rigidity, generally cast steel casting, minicomputer can also use high-quality cast iron instead of cast steel. Mainframe frame to be sub-cast, and then firmly linked into a whole bolt, casting process is complex. Homemade small jaw crusher frame can also be welded with thick steel plate, but the stiffness is poor.

2. Jaw plate and side panels

Fixed jaw and moving jaw are composed of jaw and jaw plate, jaw plate is part of the work, with bolts and wedge fixed in the jaw bed. Fixed jaw jaw bed is the rack front wall, moving jaw jaw bed hanging in the week, there must be sufficient strength and rigidity to withstand crushing reaction, which are mostly cast steel or cast iron.

3. Transmission parts

Eccentric shaft is the main axis of crusher, by a huge bending torque, the use of high-carbon steel manufacturing. Eccentric part of the need to finish processing, heat treatment, bearing lining with babbitt casting. One end of the eccentric shaft pulley, the other end of the flywheel.

4. Adjustment device

Wedge type, wedge type, wedge type, wedge type, wedge type, wedge type, wedge type, wedge type, wedge type, wedge type, wedge type and wedge type Move, the wedge of the slope of the backward fit, by the screw to move up and down after the wedge to adjust the discharge port size. Small jaw crusher out of the mouth adjustment is to increase or decrease after the thrust plate bearing between the frame and the number of pads to achieve.

5. Flywheel

Jaw crusher flywheel to store the energy when moving the jaw empty stroke, and then used for industrial formation, so that the work of machinery in line with the uniform. The pulley also functions as a flywheel. Flywheel often cast iron or cast steel manufacturing, minicomputer flywheel is often made of integral type. Flywheel manufacturing, installation should pay attention to static balance.

6. Lubrication device

Eccentric shaft bearings are usually concentrated circulation lubrication. The bearing surfaces of the mandrel and the thrust plate are generally greased by means of a manual oil gun. Moving jaw swing angle is very small, so that between the spindle and the bearing lubrication difficult, often in the bottom of the axle bearing a number of axial oil groove, the middle of a ring to the oil tank to connect, and then forced into the dry oil pump lubrication.

Jaw crusher in the use of the five prohibitions

Jaw crusher in the use of the five prohibitions

Jaw crusher is often used in the field of ore crushing machinery. But there are a lot of people in the process of continuous failure, had to shut down maintenance of the machine. SBM Tip: In fact, as long as the following is to avoid the use of several non-standard operation of the phenomenon, you can avoid damage to the machine.

1. The maintenance of the machine from time to time. Jaw crusher in the process, often because of great efforts to make the machine parts of the machine parts or screws fixed machine screws appear loose. This requires regular reinforcement of the machine screws.

2. Do not change the lubricant to the machine in time. After a period of use of the machine, the internal lubricant will reduce the lubrication effect, the machine running off the debris deposited in the lubricant will increase the wear and tear of the machine. So when the lubricant used for some time, we must promptly replaced. And the use of kerosene after the replacement of internal thorough cleaning, not to leave a little debris. This machine is not easy to wear.

3. The internal temperature of the machine is too high. Jaw crusher in the course of the friction will produce a lot of heat, if these heat can not be timely dissemination of accumulated in the machine will damage the machine. Such as the machine's axis will be because of the high temperature deformation occurred in the broken stone will be damaged. Therefore, when using the crusher must always pay attention to the internal temperature, if the machine is too high temperature on the timely shutdown, such as temperature reduction when used.

4. Did not pick out the iron in the raw material. If the iron in the raw materials, it will destroy the jaw crusher jaw. Resulting in the machine can not be used.

5. Ununiformly add the raw material. So when too much raw material into the machine will be damaged due to excessive load the machine.
