Sand has no unique advantages in nature, but it has a wide range of uses after being dried by a sand dryer. River sand, yellow sand, sea sand, etc., these sands are divided according to the size of different particles, the particle size is different, the purpose of the sand is also completely different. There is no way to divide the sand when it is wet. At this time, you need to use a dryer to dry the sand and enter it into the linear vibrating screen. Through different screen meshes, the size of the sand is divided and stored separately.

Counterweight iron sand.
The counterweight iron is a kind of iron ore raw materials in weight, its role is to balance. For example, the counterweight engineering machinery in sporting goods in weight.
For weight or pressure reuse of iron ore, iron ore, the proportion of general counterweight iron for 4.2 - 7.2 (bulk density of 2.5 - 4.8) between, customers are in terms of the drainage density (true specific gravity drainage density [1]). The product weight different needs of different proportion of the iron weight.
Counterweight iron sand density
The proportion of general counterweight iron for 4.2 - 7.2 (bulk density of 2.5 - 4.8) between, specifications: 0.2-2.0mm, customers often to drainage density (specific gravity), as the purchase of indicators. The product weight different needs of different proportion of the iron weight.
A small proportion of iron weight: 6.2-6.5 tons / m3 4.1-4.3 tons / m3 reactor
A large proportion of iron weight: 6.8-7.2 tons / m3 4.8-5.2 tons / m3 reactor

Water sand characteristics
(1) cutting speed
(2) cutting surface more smooth, more direct
(3) no large particles of sand pipe (nozzle)
(4) fine grained garnet without void
(5) there is no dust, the dust affects the cutting effect and it is difficult to clean the waste after cutting.

Pearly sand
Perlite is a by acidic volcanic glassy lava through the broken, preheating, roasting and swelling and are made with porous structure, white, loose granular materials, which has the characteristics of small volume, low thermal conductivity, good chemical stability, non flammable, non-toxic, tasteless, sound-absorbing.
Pearly sand properties
1. Perlite is a adsorption ability is very strong material, it has good infiltration, infiltration of the pearlite sand surface is wet after the release of heat.
2 pearl sand is a small capacity, low thermal conductivity, good chemical stability of the material.
3 perlite or not flammable, non-toxic and tasteless, sound-absorbing material, has good effect in the industry.

Pearly sand classification
One is the use of perlite building, the particles are relatively large, the intensity is relatively large. The other is the use of equipment insulation, mainly used to make filler, smaller particles, small strength, good thermal insulation.
Use of perlite
This product is mainly used for large ultra low temperature thermal engineering construction of the insulating layer, such as oxygen air separation unit, natural gas, liquid hydrogen, liquid nitrogen, liquid oxygen refrigerated transport such as travel. This product has good ultra low temperature thermal insulation performance.
The 1 is the perlite insulation materials, can be used to make some use of the roof insulation layer. Heat insulation effect is good, and some can also be used to make the use of crop cultivation soil configuration.
2 production of heat insulation brick used in the construction industry, etc..
3 making hand washing powder, washing powder of pearlite is other material cannot replace, structure and its screening is very strict.
