Asphalt vibrating screen for mining quarry
Product overview of Asphalt vibrating screen for mining quarry:
Asphalt sieve is the thermal aggregate classification, and sent to the silo of the device. After the thermal aggregate into the screen machine was screened into a variety of specifications. The top of the vibrating screen is provided with a distributing valve, and the hot aggregate can be directly passed into the bypass chamber without screening. Motor drive through the power, so that the two sets of vibrators for self-synchronous movement. So that the entire oscillation system along the linear trajectory to do reciprocating vibration.
Composition and principle of Asphalt vibrating screen for mining quarry:
1. Asphalt vibrating screen for mining quarry is a common biaxial inertial vibrating screen. By the two excitation shaft (eccentric shaft) in one direction of the force, it makes the material on the screen in a direction of movement. The name of the biaxial linear inertial vibrating screen reflects the structural characteristics and working characteristics of the asphalt sieve, and it is more convenient for people to grasp the vibration principle of such vibrating screen.
2. The eccentric mass and eccentricity of the two-axis eccentric wheel on the exciter are equal to each other, and the horizontal lines of the two axes on each side plate are at an angle of 40° to 45°. Two synchronous motor drive uniform rotation, the rotation in the opposite direction, the same starting phase, the same speed. In this way, the moment of inertia in each eccentric force generated in the X direction of the components of force cancel each other in the Y direction of the components of force superimposed on each other to force the screen in the Y direction for the approximate linear reciprocating vibration.
Product features of Asphalt vibrating screen for mining quarry:
1. The use of multi-layer screen, compact structure, advanced technology, a single screen can be divided into a variety of aggregate size.
2. The screen is fixed in the front and rear tight way, so it is convenient to change the screen and easy to repair.
3. Damping spring installed by tilting, can reduce the impact of equipment on the foundation.
4. Screen is wrapped in the outer box to prevent dust leakage, environmental protection and energy conservation.
5. Outer box can be wrapped with rock wool, to maintain aggregate temperature, expand the use of vibrating screen environmental conditions.
- Q:I have a vibration screen, with NJ428EM bearings, bearings can not be used for a week, the shelf is broken. Change a few sets, this is the case, what is the reason?
- With high radial load capacity, especially for heavy load or vibration load, but can not withstand pure axial load. The raceway of the bearing outer race is spherical shape, so the self-aligning performance is good, and the coaxiality error can be compensated. In addition, for the vibration screen bearing large heat, the general use of big clearance.
- Q:What are the causes of the left and right of the vibrating screen?
- The vibration sieve appears the left and right movement, one is to check the vibration motor synchronization (speed, eccentric block position is the same); two is the two vibration motor symmetry line and whether the screen frame symmetrical line coincide.
- Q:How do I seal the shaker?
- Vibration sealing strips, seals, sealing rings, vibrating screens, bucket elevator and large inclination belt conveyor can be used
- Q:A formula for calculating the natural frequencies of vibrating screens
- The above is a simple method to calculate the amount of vibration sieve. It can be seen that the biggest factor associated with the sieve component is the size of the vibrating screen mesh, mesh density, vibration frequency, material density, material viscosity, percentage of screening material and so on
- Q:What is the vibration of the shaker?
- It is the eccentricity of the vibrating screen, that is, the center of gravity of the vibrating screen does not coincide with the action line of the exciting force.It may also be caused by the looseness of a bolt. Check whether the connecting bolt is loose. If it is fastened, if it is not, it is caused by eccentricity, and only the counterweight is added to solve it.
- Q:What is the purpose of using a vibrating screen?
- Efficient and convenient screening of materials, to achieve grading purposes!
- Q:What kind of material does the sealing ring of the vibrating screen have?
- Polyurethane sealing ringWith oil resistance, corrosion resistance, high temperature and other characteristics, screening related characteristics, materials users should choose to install polyurethane sealing ring. Also because of the polyurethane effect is better, so the corresponding cost is higher.
- Q:What are the types of vibrating screens? What are the differences?
- The difference is that light screening equipment for materials for powder, granule or liquid material, mesh size is generally 1mm the following materials; and for large bulk material screen
- Q:How to calculate the production capacity of vibrating screen? How to calculate the processing capacity of vibrating screen?
- Particle shape on the influence of particle shape on material production can also affect the production capacity of the material, shape and material if it is close to the mesh shape, round shape more, more easily through the screen is empty screen, usually different materials such as the shape of strip, plate, sheet material and shape compared to circular material particles, not easy to be screened the different shape of the mesh, the ability to adapt to the different materials, the screening production efficiency and performance work ability is different. The influence of different configuration technology of screen surface material with different vibrating screen, the screen surface material is usually steel bars, steel wire, steel plate punching, rubber, polyurethane, respectively, the unfair work efficiency, the screen surface wear-resisting ability will also affect their ability to work; mesh shape is not the same as the bar screen the ability of air than other properties of the mesh shape; the size of mesh configuration is different, has great influence on particle size and particle size of the material, but it must be, the bigger screen size work ability is strong; the trajectory of vibrating screen, circular vibrating screen vibration trajectory is circular, and do linear vibrating screen linear motion trajectory, the screening efficiency is different than. Impression material of human factors on the production capacity of the equipment and the feeding flow is not less, to maintain the uniform, the probability of blocking material screening machine is greatly reduced, and the material feeding changes, and the vibration frequency of vibrating screen work did not make the corresponding adjustment, it is prone to clogging the problem is the screen material, wear, work ability is greatly reduced.
- Q:What's the effect of a rattling shaker?
- 1, the structure is more compact, reducing the weight of the fuselage2, the product is more durable, nimble and convenient3, maintenance is simpler, parts easy to repair, Tesco4, high screening efficiency, at the same time with reciprocating and top shock vibration of two kinds of movement5, will not block the screen surface, fast material, screening thoroughly
