4  General Category / iShutdown troubles and solutions / ?How To Determine The Cone Crusher Eccentricity And Dynamic Cone Strok on: June 25, 2015, 11:10:52 AM
eccentricity magnitude r0 is the center of the sphere to eccentricity and eccentricity plane by the decision.
As shown, the closed side of discharge port b = A1A2, moving cone oscillating stroke S = A2A3, open side discharge mouth b0 = b + S = A1A3. A1A3 equivalent to O as the center and the radius of the arc OA2. OA2 and OA3 according to the angle between the 2r0, the moving cone oscillating stroke is approximately: SL.2r0 / 180.
moving cone stroke swing and eccentricity of the relationship as follows:
in the design, the swing stroke and eccentricity are stochastic differ wobble and eccentricity spring stroke single cylinder engine and is not the same. As a result of multi-cylinder laminated crushing principle, which requires crushing chamber by a sufficient density of the material, we should put a greater process, but also have a higher wobble, so multi-cylinder stroke swing and eccentricity also with spring machine , single-cylinder engine is not the same. Eccentric existing multi-cylinder 2 degrees 23 minutes, and it's put away according to the following compression stroke ratio / b to identify, where S is the moving cone oscillating stroke, b is the smallest closed side discharge opening.
To ensure cone crusher cone swings motorized travel requirements, the need to accurately determine the eccentricity and eccentricity e r0 value. Moving cone oscillating stroke if appropriate, also have a great impact on the normal operation of the crusher. Hereinafter will be described in detail from the eccentric Sand Making Machine cone crusher, cone moving stroke swing method for determining the structure of these two parameters.
known data into the Raymond Mill formula, you can obtain crusher pendulum swing stroke. In addition, according to the empirical formula can also seek eccentricity: e = 0.5D.tanr0.tan, D is the dynamic cone diameter at the bottom.
eccentricity also called eccentric radius, the size of the spherical center O points to the various level is different, the general eccentricity refers to swing away from the moving cone axis of discharge mouth plane, moving cone revolution, the entire swing distance 2e. Moving jaw stroke swing and material properties, nesting size, Cone Crusher crushing cavity type and related different cavity crushers, jaw swinging its moving stroke is different.

5, rolling and crushing force
1, noise reduction
certain roll is one of the necessary conditions for the pulverized material layer. Roll is too small to give full play to the advantages of the material layer crushing, impact grinding efficiency, even layer of crushed material damage mechanism, it does not form a layer of crushed material conditions, so the traditional double roll crusher is no different. But it can not roll too much, because it will Impact Crusher tasteless waste of energy, increased wear of the roll surface, increased load bearing and shorten its life, affecting the normal operation of a roll crusher. Test and production data suggest that the cement industry with a roll press, as a cement raw material for limestone, economical roll control between 60 to 100Mpa. The average operating roll desirable 80MPa. From the current roll crusher factory application, the average pressure between the rolls must above 110MPa. Different materials, different compressive strength, the best roll is different.
tube mill noise up to 130dB or more, while the noise roll crusher is about 80dB, below the noise standard national health standards.
roll particle size distribution of the products affected. To get some powder content of the finished product, it must consume a certain energy. The number depends on the energy input of the size of the roll, i.e., roll large energy consumption, which for the purposes of the roller press is very important. For certain materials, when the feed particles is given, if you want to get a higher amount of fines, it is necessary to increase the roll, which increases unit power consumption.
4, easy to install

as to boost domestic demand, local roads, railways and other infrastructure investment is increasing, urgent need a lot of sand. In order to protect the ecological balance, the state expressly prohibit unauthorized excavation of natural sand (except clean up the river). Natural sand keep up with demand for greatly. Therefore, the development of sand will be very eager to come up on the agenda. In view of the sand after the rock blasting, mechanically sand or gravel river sand through sand and sieved mechanically formed, its strength and other properties are more favorable natural sand.
sand in terms of physical properties or chemical properties are better than natural sand. We must take a strategic height, and establish and implement the scientific concept of development, and enhance human Crusher Machine environmental responsibility, develop, and actively promote the mechanism sand equipment.
mechanism as defined in the sand: The addition to soil treatment, mechanical sand particle size sieve made less than 4.75mm of rock particles. But it does not include soft rock, weathered rock particles.
mining equipment requirements for particulate material is fine sand. In general, for flakiness material into the mill, but Vertical Roller Mill more susceptible to ground. The gravel contrary to the above requirements, its grain type, grain size requirements are very stringent. The reason is that because of its sand between the cube with edges, so that the particles have a mutual locking effect. The graded sand and make the gap greatly reduced. Meanwhile cubic round sand sand than occupy a larger surface area, asphalt and cement materials or materials from sticking together and reduce the likelihood of displacement.

1) Option 1: the silo-shaped side table instead round-shaped hopper, and the inside of the silo and paste polytetrafluoroethylene vinyl fluoride backing. The program structure is not formed in the angle plot ore bin inner liner of polytetrafluoroethylene paste can reduce the friction coefficient, thereby improving the feed situation, increase the storage capacity of the silos, but still rely on gravity to material.
engineered high-pressure roller mill, improve the working conditions of feeding system, improve the grinding efficiency of the mill.
high pressure roller mill to feed traffic has strict requirements, feeding the amount of traffic, it will cause the device to stop overloading, electrical components or even burn out the motor; the feed flow is too small, the material is not sufficiently stacked roll crush zone and thus can not form a high pressure chamber, so that the material can not be effectively squeezed. Therefore, the need to strictly control the high-pressure roller mill feeding amount. Roller mill in the grinding process, the silos blocking mine is a common fault, the cause of the failure, and the corresponding transformation methods, see analysis below.
ore silo blocking reason
fine Vertical Roller Mill grade mineral First adhered to the angle formed at the mine area, the gradual accumulation arch; material attached to the barn wall, becoming increasingly thickening of the wall material, thereby reducing the effective volume of the silo, reduced export area. Silo filled with minerals, only one had mine 'rat hole' channel. Silo block transformation method
Cone Crusher mine
