jaw crusher plays a very important role in the stone production line. it is the main crushing equipment in the stone production line configuration, because the bulk material must be crushed by the jaw crusher before it can be crushed according to the requirements of the discharge size. the equipment is equipped with secondary crushing. the simple stone production line is mainly composed of vibrating feeder, jaw crusher, vibrating screen, belt conveyor and centralized electric control. it can be equipped with cone crushing to meet different processing needs of customers. machine, dust removal equipment, etc.
the jaw crusher can process materials with a side length of 100-500 mm or less, and has a large crushing ratio, and the material after the crushing is cubic particles, the structure is simple, the work is reliable, the maintenance is simple, and the operating cost is low. in the stone production line, the large stone material silo is evenly sent into the jaw crusher by the vibrating feeder for coarse crushing.
the coarsely crushed stone material is sent to the jaw crusher by the belt conveyor for further crushing; the finely crushed stone material it is sent to the vibrating screen by the belt conveyor for screening, and several stones of different specifications are screened. the stone that meets the grain size requirements is sent by the finished tape conveyor to the finished material pile, which can meet the stone requirements of different specifications of different customers.because of the high-efficiency production, low energy consumption and convenient use of the jaw crusher, the stone production line is highly automated.
the entire production line requires almost no manual operation except for the startup and maintenance of the equipment and daily maintenance. moreover, the production efficiency is high, the running cost is low, the output is large, the income is high, the finished stone has a uniform particle size and a good granular shape, and meets the requirements of the national construction materials.
the best way to reduce the noise pollution of the jaw crusher is that the size of the spiral cone of the crusher is large, and the worker is difficult to process, and some errors will occur during the processing. the spiral cone hammer gear of the crusher, the horizontal rotating shaft, the eccentric sleeve and the main shaft have great deviations during the installation process.
the production environment of the crusher is relatively bad, which will cause the gear to sway in the tooth and increase the friction. the eccentric sleeve and the horizontal axis of rotation will rotate unbalanced. the jaw crusher is commonly known as smashed, also known as the tiger's mouth. the crushing chamber is composed of two jaws, which are composed of two jaws, which simulate the two movements of the animal to complete the crushing operation of the material crushing operation.
kefid'crushers are mainly used as coarse crusher and medium crusher in mining, building materials and infrastructure. according to the width of the feed port, it is divided into three types: large, medium and small. the feed port width is larger than 600mm for large machines. the feed port width is 300-600mm for medium-sized machines. the feed port width is less than 300mm for small-sized machines. machine, the highest compressive strength of the crushed material is 320mpa.
the jaw crusher is simple in structure, easy to manufacture and reliable in operation. the working part of the jaw crusher is two jaws, one is a fixed jaw (fixed), the vertical (or the upper end is slightly inclined) fixed on the front wall of the body, and the other is the movable jaw (moving), the position tilting, forming a large and small crushing cavity (working cavity) with the fixed jaw. the movable jaws periodically reciprocate against the fixed jaws, sometimes separated and sometimes close. when separated, the material enters the crushing chamber, and the finished product is discharged from the lower portion; when it is close, the material between the two jaws is crushed by bending, bending and splitting.
jaw crusher is one of the most familiar crusher equipment. it is often used to crush stone. the feeding link is the first step in the operation of the jaw crusher. the effect of this step has a direct impact on the operation of the follow-up production. if the feeding link is not in the right way and timing, it may lead to the part. the damaged parts, causing the occurrence of the failure, thus affecting the normal production work, the following for you to explain the jaw crusher feeding link should pay attention to what?
1. check the operation of the jaw crusher to see if the operation is good, whether there is noise, if the operation is normal, then feed operation. for the first time, we should follow the principle of small size material priority and gradually add.
2. during the feeding process, the operator should prevent materials or iron impurities which do not meet the technical parameters from entering the jaw crusher, so as to avoid the damage of the jaw crusher caused by overload operation and even the fracture of the jaw crusher.
3. after the jaw crusher stops working, it is necessary to pay attention to cleaning up the impurities in the feeding link, so as to avoid blocking phenomenon in the next operation.
it is the basis of guaranteeing the normal operation of jaw crusher to do well the work of feeding link. it needs the attention of feeding operator and the person in charge. good cooperation is the key to improve the production efficiency.
jaw crusher is one of the commonly used equipment in material crushing production line, which is widely used in mining, smelting, building materials, highways, railways, water conservancy, and chemical industries. what are the main components of it?
1. standthe frame is a four-wall rigid frame with upper and lower openings. it is used to support the eccentric shaft and bear the reaction force of crushing materials. it requires sufficient strength and rigidity. generally, the whole cast steel is used to cast, and the high-quality cast iron can be used to replace the cast steel in the small machine. the rack of the mainframe needs to be segmented and bolted to form a whole and the casting process is complicated.
2. jaw plate and side guard plate. both fixed and movable jaws are composed of a jaw bed and a jaw board, which is the working part fixed on the jaw bed by bolts and wedges. the jaw bed with fixed jaw is the front wall of the frame. the jaw bed with movable jaw is suspended on the circumference. it should have enough strength and stiffness to withstand the crushing reaction, so it is mostly cast steel or cast iron.
3. transmission parts the eccentric shaft is the main shaft of the crusher, which is made of high carbon steel by a large bending torsion force. the eccentric part must be fined, heat-treated, and bearing bushing cast with babbitt alloy. one end of the eccentric shaft is equipped with a belt wheel, and the other end is equipped with a flywheel.
4. adjusting device the adjusting device includes wedge type, backing plate type and hydraulic type, generally adopting wedge type, consisting of front and rear two wedges, the front wedge can be moved forward and backward, against the back push plate; the rear wedge is adjusting wedge, can be moved up and down, the two wedges inclined face backward to fit, the screw makes the rear wedge move up and down and adjusts the size of the outlet. the outlet adjustment of small jaw crusher is realized by the number of gaskets between the support of the thrust plate and the frame after the increase or decrease.
5. flywheel the flywheel of the jaw crusher is used to store the energy of the moving jaw during the empty stroke and then is used for the industrial formation to make the mechanical work more uniform. the pulley also acts as a flywheel. flywheels are often made of cast iron or cast steel, and the flywheels of minicomputers are often made into integral ones. when making flywheels, pay attention to static balance when installing.
6. lubricating device eccentric shaft bearings usually use centralized circulating lubrication. the supporting surface of mandrel and thrust plate is usually lubricated by manual grease gun. the swing angle of the movable jaw is very small, which makes it difficult to lubricate between the mandrel and the bearing bush. some axial oil grooves are often opened at the bottom of the bearing bush, and a circular oil groove is opened in the middle to make it connected. then dry butter is forced to be injected into the oil pump for lubrication.
