We Want Stone Crushing Machines on Contract Basis
Stone Crushing Machines Introduction:
Crusher broken material impact principle theoretical design study a crusher, it is actually developed from hammer crusher based on a new and efficient crusher, stone crushing machines can be usedcrushing limestone, asbestos ore, coal, quartz sand, calcium carbide, dolomite, pyrite and other materials. Can be used to rough broken, broken, broken bits can also be used.
Especially for high-grade highways following the non-slip surface layer of asphalt concrete fewer graded aggregate requirements of basalt, andesite and other hard materials processing power requirements 100t / h or more, by Liming Heavy production of PF series stone crushing machines discharge size and processing power are more able to adapt to the needs.
Stone crushing machines impact crushed ore crushing equipment. For the application of mechanical energy, the use of the impact energy the crusher crushing principle, superior extrusion crushing principle better than to the static pressure of the crusher.
Jaw crusher basically to squeeze the crushing action principle based crusher, stone crushing machines impact "freedom" crushing principle of crushed ore. It belongs to the energetic crusher.
Stone Crushing Machines Common Maintenance:
Crusher is a fast speed, the inertia of the equipment, do the normal operation and maintenance work is extremely important for the long-term safe operation of the equipment.
Before driving to carefully check the equipment, such as fasteners are not loose and easy to wear pieces need to be replaced, the lubrication and cooling system is good;
When driving by the broken system boot sequence, first start dusting equipment, and then open the transportation equipment, and then the crusher and feeder. First empty running, confirmed that no abnormalities before feed production;
Parking is to be carried out in accordance with the order of the production process, with the car in reverse order. We must first stop the feeder, the material emptied until the crusher to shut down the main motor and the conveyor system;
Feeding should be uniform, to prevent more than the specified blocks degree materials and metal debris feeding;
Equipment operation process should be careful to check the work of the lubrication system regularly add or replace the lubricant. Rotor bearing temperature should be below 60°, the maximum does not exceed 70 °;
When the product particle size is too large, you should be down to check the impact plate for wear, or to adjust the pads and the gap between the counter plate;
Good equipment sealed and workshop dust collection.
Working Principle:
Stone crushing machines is a rebound effect of the high-speed impact of the board hammer and counterattack plate, so that the material by repeated shocks broken machinery, the main structure: rack rotor plate hammer, counterattack plate, side guard plate.
Work, driven by the motor, the rotor high-speed rotation and materials into the active area of the plate hammer, stone crushing machines plate hammer on the rotor, and later was thrown to the the counterattack device again broken counterattack board bounce ore and then with the other ores thrown in the back of the board hammer or rotor collide with each other, therefore, in the first crushing chamber ore was crushed by repeated shocks. Some ore broken in the first crushing chamber to a certain size, after a counterattack the gap between the plate and the rotor row to the second crushing chamber, continue to be repeated strikes, until it reaches the ideal particle size only by the bottom row of ore crusher discharge port .
Stone Crushing Machines Performance:
Crusher appeared later, but the development of fast. At present, it has been our cement, building materials, coal and stone and mineral processing and other industrial sectors are widely used in a variety of ores and crushing operations, ore coarse crushing equipment used. stone crushing machines has been growing so rapidly, mainly because it has a need for superior characteristics:
1, Broken than great. General crusher crushing ratio does not exceed 10, and stone crushing machines crushing than is generally 30-40, up to 150. Therefore, the current popular three-stage crushing process, if the use of stone crushing machines, it would only take a while or both ends can be completed, which greatly simplifies the production process, saving investment costs.
2, Crushing, high efficiency, low energy consumption. Because of the the general ore impact strength is much smaller than the compressive strength, the same time, due to the ore by blow board the high-speed and after several attacks, the ore along the jointed interface and organizations vulnerable first strike crack class crusher crusher, high efficiency, and low power consumption.
3, Uniform particle size, the less over crushed phenomenon. Subject to a greater degree of crushing in the crushing process, the lump ores, but the smaller particles of the ore, not to be broken under certain conditions, and uniform particle size of the crushed product, less over crushed phenomenon.
4, Can be selectively broken. Impact crushing process, useful minerals and gangue first rupture along the joint plane, in order to facilitate useful minerals monomer separation, especially For the coarse crushing disseminated useful minerals, this point is more significant.
5, Adaptability large. This crusher crushing brittle, less fibrous and medium hard ore, particularly suitable for limestone and other brittle ore crushing, cement and stone industries Crusher still very appropriate.
6, The devices are small, light weight, simple structure and easy maintenance.
Given all the advantages of stone crushing machines, countries are widely adopted, and vigorously develop. However, in crushing hard ore larger stone crushing machines board hammer (pads) and counter plate wear, in addition, the Crusher is a high-speed rotation by the shock to broken ore machine parts processing accuracy requirements and static balance and dynamic balance, in order to extend the service life.
