How long does it take for natural stacking and dehydration of wet sand?

 Artificial sand is generally stored and dehydrated for 3 to 5 days to reduce the water content to within 6% and become stable.

The artificial sand and gravel powder content varies depending on the initial moisture content. Generally, the stone powder content is in the range of 10% to 17%.

When the initial moisture content of wet sand is 15% to 17%, the dehydration speed is fast within about 48 hours in the initial stage. Generally, the moisture content can be reduced to 8% to 10%. When the moisture content drops to 8% to 10%, it can be reduced to 6%. The dehydration speed slows down significantly around %, generally taking 3 to 5 days. Based on the daily production of 15,000 tons of finished sand and the daily sand consumption of 1 to 15,000 tons, the finished sand warehouse has a storage capacity of 50,000 m2, and the natural dehydration time is about 5 days.

Measures to effectively control the moisture content of artificial sand in stacking sand bins

1. In the general system process, most of the water in the sand must be removed mechanically first. At present, the vibrating screen dehydration process is the most used. The sand dehydrated by the linear dewatering screen can dehydrate the sand with an original moisture content of 20% to 23% to 14% to 17%. There are also dewatering technology with good dehydration effect and correspondingly large investment costs. Vacuum dehydration and centrifugal dehydration.

2. Artificial sand unloading, storage dehydration and artificial sand extraction are carried out separately. Generally, the water content can be reduced to less than 6% and stable after 3 to 5 days of storage dehydration.

The difference between quartz and mica

Mica and quartz are common minerals that play an important role in mineralogy. Although they are both silicate minerals, there are clear differences between them. First, mica and quartz are very different in appearance. One of its distinguishing features is that mica exhibits a layered structure that can be easily peeled off into thin flakes. Quartz, on the other hand, is a uniform crystal with no layered structure. Additionally, mica is usually dark in color, such as black, brown, or green, while quartz is usually clear or white. Secondly, mica and quartz also differ in their physical and chemical properties. The hardness of mica is usually between 2.5 and 4, which is relatively easy to be scratched; while the hardness of quartz is very high, 7, which is a very hard mineral. In addition, mica has good refractive properties and electrical properties, while quartz is an excellent piezoelectric material.

Sandblasting nozzle classification and use

Using high-pressure air as a power source to drive abrasive particles to hit objects within a certain range will produce a great impact. The function of the sandblasting nozzle is to spray abrasive particles on the object evenly and efficiently. Sandblasting nozzles can be divided into: straight hole sandblasting nozzle, Venturi sandblasting nozzle , double Venturi sandblasting nozzle, angle sandblasting nozzle Straight hole nozzle: There are only contraction section and straight section inside, the structure is simple and easy to manufacture. This kind of nozzle cannot overcome the vortex phenomenon existing at the inlet end, and the pressure loss is large; the abrasive velocity at the outlet is less than 100m/s under the pressure of 0.7MPa.

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 ...
