Will Vibrating Screen Coupling Play an Important Role

Will Vibrating Screen Coupling Play an Important Role

How much do you know the coupling in mining industry?It is a universally mechanical transmission component which connect the two shafts together.The two shafts can not be separated along the rotation axis and passing a member torque when the machine running. Only after the machine stop and open connection, two axes can be separated. Couplings are already standard parts, you can select the appropriate coupling in accordance with national standards and requirements for use when using.

vibrating-screen-coupling

Since the manufacture and installation errors, deformation after impact bearer and temperature changes, the coupling of the two coupling shaft there is some degree of relative displacement. Therefore, the coupling between the gear unit and the clutch selection cross coupling. Oldham coupling is opened by the end faces of the coupling halves and a groove on both sides of the intermediate plate with protruding teeth formed. Because the convex teeth can slide in the groove, it is possible to compensate for the installation and during the operation of the relative displacement between the two shafts. This coupling parts and materials are available 45 steel work surface heat treated to improve its hardness; can also be used when less demanding Q275 steel, heat treated. 

coupling

When put into use,it is better to add lubrication grease from the middle of the hole to reduce friction and wear.Because the half-coupling and intermediate plate composed of mobile vice, not relative rotation, so the drive shaft and the angular velocity of the driven shaft should be equal. But working in relative displacement between the two shafts case, the intermediate plate will have a great centrifugal force, thereby increasing the dynamic load and wear. So users should pay attention to its operating speed is not greater than the predetermined value.

Dewatering Screen in the Application of Potash Feldspar Ore Dressing Process

 Dewatering Screen in the Application of Potash Feldspar Ore Dressing Process

At present most of the production of potassium feldspar manufacturers in product dehydration link with spiral classifier and filter press to dewatering process, but the spiral classifier separation material, low working efficiency, filter press investment in energy consumption. And in the production of non-metallic mineral potassium feldspar, if through the spiral separator slag water separation, separation after finished product moisture content is exorbitant, can't do the heap.

potash-feldspar-in-dewatering-screen

Why do we choose to use dewatering screen? This is because that dewatering screen not only can be used for ball mill ore grading but can be used in potassium feldspar product dehydration. Potassium feldspar product dehydration link in traditional production process is processed by filter press, the disadvantage is that investment in energy consumption and low working efficiency, dehydration after finished the actual water content is high. Dewatering screen in the application of potash feldspar ore dressing greatly improve the production efficiency, reduce the energy consumption, reduce the area.

The Tin Powder Screening Problem for Ultrasonic Vibration Sieve

1.The output powder efficiency of ultrasonic vibration sieve is low, there is no finish powder or less after sieving, if this kind of situation appears, we need to check the performance of ultrasonic acoustic, whether it is due to the poor quality, resulting in screen mesh blockage, causing the finished powder cannot be sieved out.
2.Larger and smaller size of tin powder exceed the standard, when confronted with the problem, we first need to check screen mesh of ultrasonic vibration screen, uneven powder size mostly may be due to poor quality of screen mesh, aperture size is not same when manufacturers make the screen mesh, or some parts of screen mesh are damaged after long time use, here it requires us select standard and qualified screen mesh from the regular manufacturers, regular check of screen damage is also required.

3. The oxygen content of tin powder is excessive of the standard, it is mainly because of poor sealing ,which lead to air leakage, it is necessary to ensure good sealing and check whether the sealing ring and other sealing place are qualified or not, vibration sieve rubber sealing ring after long time use, it will occur deformation or a series of problems which results in the increase of oxygen content in tin powder. Therefore, check the sealing ring regularly, especially in the case of high temperature in the summer.
4. Unstable ultrasonic vibration screen will cause the screen mesh heating and screen plugging seriously, before using ultrasonic vibration sieve, please select and set the vibration motor power well, check the equipment adjustment flexibility and check if discharging outlet is smooth or not.

How to Distinguish Between the Shaft and Shaftless Drum Screen?

How to Distinguish Between the Shaft and Shaftless Drum Screen?

The drum screen can be divided into two structures,shaft drum screen and shaftless drum screen.The common point of them is that they can both use for the bulk materials.But for some relatively complex material properties,we should choose the suitable drum screen according to the working condition.Here PK Machinery will give you a better understanding about it.Hope the following passage will help you.

Difference:

1.Methods of Installation 

The roller device of the shaft drum screen is arranged on the frame. 

The screen of the shaftless drum screen is installed horizontally

2.Working Principle

For the shaft drum screen,after the drum motor reducer are connected together by coupling means, the drive roller means rotatable about its axis. When the material into the drum unit, due to the tilt and rotation of the drum unit, so that the material flip and scroll the screen surface, so that qualified materials through the discharge port at the bottom of the rear end of the drum is discharged, substandard materials (sieve product) by the end of discharge rollers discharge port. As the material within the drum flip, roll, so that the card material in the meshes can be ejected, to prevent clogging of the sieve.

drum screen

For the shaftless drum screen,the motor drive pulley or sprocket gear roller, usually the slower speed, roller length can be longer, so that the material fully screened. Internal drum lifting plate may cause the material moves forward on the discharge end of the drum sieve material, sieve material discharge hopper along the drum income.

3.Application

Shaft drum screen generally used in a large proportion of granular materials, such as: sand, coal, limestone, fertilizer, compost, ore.

Shaftless drum screen always used in smaller proportion of materials, such as: garbage, wood, charcoal, compost, building materials, chemical products etc.
