Installation mothod of Polyurethane Screens

Correct installation of the screen

The installation structure of the screen should be selected according to the size of the screen aperture. For large holes (the recommended diameter exceeds 60mm), it is recommended to use a bolt-type fixing structure. Due to a large amount of material processed by the large-aperture screen, it has a greater impact on the screen surface. The fixed form of the screen with other structural forms is easy to loosen. After the screen is loosened, it strikes each other with the support beam, which shortens the life of the screen.

Improper use will affect the service life of the polyurethane screen.

After selecting the correct polyurethane screen, it needs to be used reasonably to maximize the performance and service life of the polyurethane screen. However, this is easily overlooked by many users when using polyurethane screens.

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 ...
