subject: Hammer crusher and Troubleshooting Overview [print this page] Overview of broken machinery Overview of broken machinery
1. crushed, solid material in the external force, to overcome the cohesion, leaving the solid material crushing process.
2. cement production in the crushing of the significance of the material: in the cement production process, a large number of solid raw materials, fuel or semi-finished products need to broken, aimed at improving the efficiency of drying and grinding equipment, but also to facilitate pre-all of the materials, transportation and storage. To produce 1 ton of cement, you need more than 4 tons of crushed material, which needs about 2 tons of material crusher machine. To produce 1 ton of cement power consumption of 100%, then the materials for crushing and grinding power consumption about 70%.
3. the crushing method of classification (1) crush, the material between the two work surface pressure by the slow growth of the broken. This method is used for crushing of brittle hard materials.
(2) ground, the material in the two relative sliding of the face or between the various shapes of grinding by friction and grinding. Materials used in small crushing.
(3) split pieces, the role of material objects by two wedge was broken. Such as: jaw crusher.
(4) crushing, the material in an instant broken by the impact, such as hammer crusher.
4. crusher Category (1) jaw crusher, jaw plate has two components: a fixed jaw plate, a jaw plate is active through the drive mechanism so that the two sometimes close and sometimes left jaw, near the jaw when the two materials are pressed between the plates broken, leaving less than a gate-size material is discharged qualified. Jaw Crusher is divided into: simple swing, complex combination of swing and swing three.
(2) hammer crusher, the rotor is divided into single and double rotor crusher. The following special statement.
(3) Impact Crusher: a. single-rotor impact crusher: the rotor against the board, back board, composed of the body.
b. Double Rotor Impact Crusher.
c. Combined Impact Crusher.
d. counterattack hammer crusher.
(4) roll crusher, simple structure, suitable for crushing low viscosity and hardness of wet materials. Divided into: a. Single-roll crusher.
b. Double Roll Crusher, clay crusher, the following detailed description.
c. multi-roll secondary and tertiary crushers.
(5). cone crusher. a. crushing cone crusher.
b. in the crushing cone crusher.
Second, mining limestone crusher (TKPC16002.HL2)
The crusher is currently the single cement plant has been put into production in the largest single section of one crusher machine. From the use of more than two years to see, the aircraft designed, compact structure, installation, commissioning, easy maintenance, materials adaptable, table and large output and high efficiency. Production capacity and operating costs from reaching the desired results.
Required under the contract, the capacity breakers I need to meet two 5000t / d clinker production line of production, average daily production in the 16,500 tons of limestone above. As LIMESTONE system side cantilever stacker used cantilever belt conveyor capacity by the boom lift angle greater impact (bracket in horizontal below the table when the yield of 1800t / h, cantilever Yang, the capacity decreased gradually rose to the highest output was only when the table and 900t / h or so). As the two main ore mine discharge port are in the pitch more than 2 km, there is often a lack of available materials appears to be material phenomenon crusher idling. To this end the crushing machine when the production requirements to achieve the 1400t / h or more. Production practice for two years proved that the crusher can meet the production capacity needs.
Tianjin Institute of the aircraft through the installation, commissioning and production process guidance, and ongoing optimization of its technological innovation, and at this stage the aircraft capacity to fully meet the design capacity, in the feed and the next process conditions allow, the aircraft production there is still much room for improvement. Since been put into production, the machine rotor, grate screen, liner, bearing lubrication, electrical and some other improvements have been targeted, and achieved the desired results.
May 2002, the original screen grate grate grate plate replacement to overcome the grate bars are often broken, the material disadvantage and poor ability to adapt, improve the reliability of screening grate. Greatly extended the life of screening grate.
February 2003, the replacement of the two rotor hammer plate. Since the original rotor disk narrow hammer crusher machine, hammer shaft easy to break and get stuck, maintenance workload and difficult. New rotor disk increases the width of hammer, and the installation of the sleeve, the hammer shaft and the rotor to improve the work life. Through several of the hammer shaft material and heat treatment process improvements, new materials are used in steel hammer shaft, working in good condition. 1 # hammer rotor shaft since December 2003 is still in use, have not yet found a crack or fracture and wear in good condition, its performance is much better than the original material hammer shaft.
