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
