Is what we call the ore from a mine mining down contains some valuable minerals, rocks, ore after crushing, grinding and other processing step by step can be used in metal mining, metallurgical industry, chemical industry, construction industry, iron (public) road construction units, cement and sand industry and other fields of engineering. Generally speaking, ore minerals and gangue minerals ore composition. Ore mineral is refers to the ore can be used in metal or nonmetal mineral, also known as the useful minerals.

Ore mineral according to the mineral content of how much can be divided into the following three:

1. The main mineral, means more content in ore, and mineral plays the leading role in a certain minerals;

2. Secondary mineral, means less content in the ore, the ore grade mineral; it won't do to

3. Trace minerals, refers to the general content in the ore is seldom, does not have big effect on ore minerals.

Some characteristics of mineral elements in the ore, such as nickel ore trace platinum group elements in minerals, though its content is very little, but has high comprehensive utilization value, this kind of trace minerals still has great economic significance.

Used for mineral processing equipment usually have jaw crusher, counterattack crusher, cone crusher, hammer crusher, roll crusher, impact crusher, etc.

For ore crushing, the use of cone crusher effect more obvious:

1. As a result of the ore crusher production capacity between 600 ~ 800 t/h, 25 ~ 40 times that of ore crusher ability, effectively solve the original ore crusher for lower production led to high rates of operation, without maintenance time.

2. Can complete the lump ore crushing. Biggest crushing particle size is 1000 * 1200 mm, effectively solve the original ore supplies, while cannot be used to store large amounts of large deposits.

3. The product particle size is small, only for 2 ~ 15 mm, effectively solve the original ore particle size is large, often blocking even influence the production of grinding machine is used when the problem of the valve.

4. Two kinds of material mixing uniformity, good desulfurization adding quantity increase of the ore. The adding quantity can reach 60%, effectively reduce the cost of the original burning material.

5. Power consumption declined. 1 ~ 2 in ore consumption per ton of KWH/t, can save electricity, 100000 yuan a year.

6. Effectively improve the labor intensity of workers and working environment. Due to the high degree of automation of ore crusher, without human contact materials, significantly improve workers' labor conditions.
