Use and maintenance of banana sieve

The double-layer banana sieve is mainly used for coal grading, desliming, dehydration and de-intermediation, and also suitable for the screening and grading of other minerals. The double-layer banana screen includes side panels, vibration exciters, motors, belt drives, auxiliary shaft pairs, buffer springs, upper sieve plates, lower sieve plates, excitation beams, upper beams, lower beams, lifting beams, etc. Double-layer vibrating sieve for banana sieve. The upper sieve plate has a large inclination angle, and the lower sieve is basically arranged horizontally. This structure can efficiently process a large amount of feedstock through thin-layer screening. The feed material passes through the upper sieve plate at a high speed to make the powder material get preliminary separation. The material moves at high speed on the sieve plate to separate it into thin layers.



Maintenance of banana sieve

Before installation, it is necessary to check whether the parts are intact and complete, and to conduct a thorough cleaning and inspection of the installation foundation of the sieve machine. The embedded steel plates under the four spring support seats must be in the same horizontal plane. After the vibration isolation frame is in place and the vibration isolation spring is adjusted to be perpendicular to the upper and lower supporting surfaces, the spring seat and the lower embedded steel plate can be welded firmly. When welding, only weld both sides of the spring, not both ends of the spring seat. Before installing the vibration isolation spring, check the dimensions and stiffness values ​​to ensure that the stiffness and height of each group of springs are consistent. After the springs are installed, all springs are required to be vertical to the upper and lower supporting surfaces. The exciter and the screen box have been installed at the factory and shipped together. The original assembly condition must be checked at the installation site and the connecting parts must be re-fastened.


The sieve machine should avoid starting with material, and start feeding after it starts and runs smoothly. The feeding should be stopped before stopping, and the sieve can be stopped only after all the materials on the screen surface have passed. During the working process, always check whether the sieve machine is running smoothly. If it is found that the operation is abnormal or there is an impact sound, it should be stopped and checked immediately. In the event of a sudden accident, the material on the screen surface should be removed to avoid starting with materials when the machine is turned on next time, which will affect the service life. Frequently check the abrasion of the sieve plate and liner. If severe abrasion or cracks in key parts are found, they should be replaced or repaired in time.

Chromite purification processing method

At present, chromium ores with industrial value are generally chromium-magnesia spinel or chromium-iron spinel minerals, which contain a large amount of chromium oxide, with a content of about 18% to 62%, and generally also contain metals such as aluminum and nickel. Its characteristics make the chromium ore beneficiation process present a rich and diverse state. Due to the properties of chromium, chromium ore beneficiation processes include gravity separation, magnetic separation, flotation, combined beneficiation, chemical beneficiation, etc. Commonly used in industry are single gravity separation, single magnetic separation, and gravity-magnetic combined beneficiation processes. In terms of equipment selection, shakers and jigs are mostly used in the gravity separation stage, while the equipment selection in the magnetic separation stage is determined based on the magnetism of the ore.

The classifications of quartz sand

  1. Ordinary quartz sand: The surface of ordinary quartz sand seems to have a layer of yellow skin, and some have large particles and strong fire resistance. It is a kind of quartz sand processed by the manufacturer after using natural quartz ore in the production process, such as washing and drying. No impurities can be seen in the quartz sand through the second water treatment filtration. It is the best choice for chemical water treatment. It can block the sundries suspended in the water and maintain the quality and beauty of the water. 2. Refined quartz sand: Refined quartz sand is a mineral made by the manufacturer after carefully selected quartz stone. According to different requirements of users, the range used is also different. But generally the main use of refined quartz sand is in glass products, because refined quartz sand is refractory and precision casting, especially suitable for fireproof glass materials.

Slove method of the clogging of trommel screen sieve

The drum screen is a simple screening device.  The trommel screen  is easy to close and collect dust, the maintenance is small, the maintenance is simple, and the service life is long. It is a device frequently used in refractory materials, coal, river sand classification, and sandstone classification. The advantage of the trommel screen is that the structure is not complicated so that the device can be quickly operated, and when the trommel has problems, people can easily solve it. But what should I do when the screen of the trommel screen is blocked? The following screen will introduce several ways to solve the phenomenon of blocking the net. The trommel screen sometimes adopts a mechanism added to the fixed frame, and then the mechanism rotates to drive the belt mounted on the belt to continuously smear the surface of the sieve hole, thereby sucking out the raw material particles blocked in the sieve hole. One of the disadvantages in practice is that it produces a lot ...
