Product Description:

ZK series straight line vibrating screenabsorbs Germany technology. With the world advanced technology and uniqueeccentric structure, its used in coal, metallurgy, electric power,demud,demedium as well as dry and wet classification to medium and finematerials.

Features and Benefits :

1.Thelateral plate adopts cold processing technology and is bended symmetrically sothere is no welding joint and life time is extended. However, many othermanufacturers adopt welding fold process. Thus, it is easy to crack. Meanwhile,we add many steel bars into the lateral plate to ensure its high strength.

2.Weadd high strength bolt connection between beam and lateral plate and the beamis easy to change.

3.Softcoupling connection is adopted between motor and vibrator. Compared withuniversal joint connection, it has longer lifetime、lower cost and installation condition as well asless impact to motor.

4.Thescreen is supported by rubber spring,compared with the metal spring,it has theadvantage of longer lifetime, anticorrosion,operation smoothly,low noise,smallimpact to screen and structure.The picture below is Commissioning platform forsceen,there will be a 6.5 hours worktest for each screen before leavefactory,the core of worktest consisting of checking the temperature ofbearing,amplitude of vibration and so on.Providing delivery inspection andworktest report strictly. Ensure that product performance and stability afterdelivery.


6.Forsteel woven mesh adopt the fixed form of tight hooks on both sides and middletension. It is convenien for adjustment and replacement . Protect side platehas a very good protection effect to vibrating screen .Polyurethane mesh in theform of bolt to fixed mesh. Screen mesh is undulated, it can quickly dispersedmaterial, improve the efficiency of screen.


7.Picture:mesh and beam(Note:between the mesh and beam ispolyurethane to protect mesh)


8.Vibrating Exciter of Yifan adopt two couple bearings(four bearings). Improve thestability of the vibrator and work life. Ordinary manufacturer also installonly one set of bearings. Exciter performance is not stable, the bearing iseasy to damage.

Q:Which is better, a linear vibrating screen or a round vibrating screen?
The working principle of circular vibrating screen is mainly composed of screen box, a screen, a vibrator and vibration damping spring composed of circular vibrating screen. The vibrator is installed in the sieve box side, by the motor through the belt driven centrifugal force of inertia, forced vibration sieve box.
Q:What is the quality of the vibrating screen related to the factors?
The workload refers to the quality of the screening unit at the time the material in the vibration sieve size; and the size of the screening efficiency is the most critical factor, the screening efficiency refers to the percentage of fine grain weight after the screening and screening sieve weight products to the material contained in the aperture size is less than the ratio. It is said that the extent and quality of the product screening screening operation.
Q:What is the difference between a circular vibrating screen and a linear vibrating screen?
Circular vibration sieve and line screen work is not the same, the material on the screen of the line is jumping up and down and move forward, the trajectory of circular vibration sieve is an ellipse trajectory, two dice are not the same, and the shape is not the same.
Q:What kind of vibrating screen is used in the coal preparation plant?
The linear vibrating screen is suitable for coal preparation,The linear vibrating screen is suitable for coal preparation
Q:What's the difference between YK series round vibrating screen and YKR series round vibrating screen?
YKR in which Y stands for circular vibrating screens, K stands for block eccentricity, and R denotes flexible connections. Without R, it is an ordinary belt connection. However, most of them are now flexible connections, and even vibrate directly with the side plates.
Q:What should be paid attention to when using the motor on the vibrating screen?
Vibration motor foot bolt should be based on the corresponding diameter of not less than 8.8 of the high strength bolts with a spanner, reliable fastening and using anti loosing measures, there should not be any slack. Generally use flat pad and double nut fastening and prevent loosening. Tighten the assembly bolts in the order shown.
Q:What is the composition of a self balancing vibrating screen?
Feeding parts: including feeding hopper, pressure door, inlet suction pipe.
Q:Why is the bearing of the vibrating screen overheated?
Bearing temperature is too high, mainly due to the temperature rise when the bearing work too fast, causing the bearing parts to expand, so that the work gap of the bearing becomes smaller, causing severe friction
Q:What are the structural principles of an inertial vibrating screen?
Two rolling bearing vibrator 5 is fixed on the screen box in the middle, with emphasis on the 4 ends of the vibrator shaft wheel 6, adjusting weight 7 in biased wheel in different positions, can get different inertia force, so as to adjust the amplitude of the sieve. The motor installed on the fixed base drives the main shaft by the triangle belt pulley 3, so that the sieve generates vibration. A central circular trajectory; because of the action of the spring lining is both ends of trajectory sieve is elliptical to oval track direction near the feed end in advance, which makes the material speed increase; according to the different requirements for the production and the operating efficiency of the screen, can be installed into different slopes (15 ~25 OC) in the elliptical orbit near the direction toward the discharge end, in order to make the material progress slowed, is conducive to improve screening efficiency.
Q:How to deal with the side crack of vibrating screen?
The repair area at the top of the side plate grinding, grinding angle and lateral primer. In the medial angle on with reinforcing plate on both sides of the weld in at least 3.12 riveting riveting bolts) when all rivet bolt riveting, in the repair area painted lacquer topcoat. After drying, with SIKA glue around the reinforcing plate sealed to prevent corrosion. The analysis of the application of high frequency vibration in quartz sand production process in the maintenance of sieve shaker common fault and maintenance method of how to choose the appropriate circular vibration sieve application specific process of vibration screening equipment in vibration screening in industry and agriculture.
