Aluminum Introduction

Aluminum is mined on a large scale as bauxite (containing about 50% Al 2O3·2H2O). Australia, Guinea and Brazil are the largest producers of bauxite ore in the world. The uses for aluminum in modern society are countless: cans and foils, kitchen utensils, building cladding, structural engineering applications where a strong, light, easily machined material is needed. Although its electrical conductivity is only about 60% that of copper per area of cross-section, but it is used in electrical transmission lines because of its lightness and price. Its various alloys are of vital importance in the construction of modern aircraft and rockets. Evaporated in a vacuum, it forms a highly reflective coating for both visible light and radiant heat. These coatings form a thin layer of protective oxide and do not deteriorate as do silver coatings. These coatings are used for telescope mirrors, decorative paper, packages and toys, and in many other applications.

Aluminum dressing equipment

Aluminum ore is mainly a diaspore ﹑ a boehmite and gibbsite. These are aluminum ores. Industrial grade aluminum ore indicators border, pit mining open-pit mining and the ratio of the Al-Si are 1.8 ~ 2.6, Al2O3 ≧ 40%; the lowest industrial grade, aluminum-silicon ratio of the open-pit mining ≧ 3.5, pit mining ≧ 3.8, Al2O3 ≧ 55% .

Aluminum ore primary crusher

Here we recommend to you Jaw Crusher as aluminum ore primary crusher. There are both double-toggle jaw crusher and single-toggle jaw crusher. Also there is more advanced European Jaw Crusher apart from ordinary jaw crusher.

Aluminum ore secondary crusher

For aluminum ore secondary crushing, you can choose cone crusher or impact crusher. What’s the difference is the final products’ shape. After crushed by impact crusher, the final products will be of good, cubic shape and without tensility and cranny. Therefore for highway and railway surface as well as water and electricity industry, we recommend to choose impact crusher.

Aluminum ore grinding machine: Ball Mill

Ball mill is the most traditional grinding machine in the aluminum ore grinding. With simple structure and reliable quality, ball mill is much popular in various minerals’ grinding.

Antimony information

Antimony is often found associated with sulphide minerals and is generally produced as a by-product of gold mining activities. China, Russia and South Africa are the world’s major producers of antimony. Principal identified world resources are in Bolivia, China, Mexico, Russia, and South Africa.

Antimony ore Crusher

Antimony ore crusher includes jaw crusher, impact crusher, cone crusher and mobile crusher, and they are widely used in the whole antimony mining processing.

Jaw Crusher as primary crusher. It is widely used in fields of mining, metallurgical, construction, smelting, hydraulic and chemical industries, etc.

Impact crushers is optimized and widely applied in the first and secondary crushing.  It has features: Locking sleeve assembly Connection; Blow bar with high chrome; Hydraulic or hand opening; Special impact plate; Cubical shape of final product; Easy maintenance; Reliable performance

Cone crusher is suitable for crushing various mid-hard and above mid-hard ores and rocks. The unique crushing chamber replace system can quickly replace components in crushing chamber to meet different size requirement.

Antimony processing plant

The unit processes employed for gold and antimony recovery from ore include:

Two stage crushing plant: Our antimony crushing plant includes jaw crusher as primary crusher and cone crusher as secondary crusher.

Conventional ball mill: Ball mill is the suitable grinding mill for grinding antimony. Besides ball mill, vertical antimony mill can be used as antimony grinding mill.

Antimony processing plant supplier

We offer a wide range of medium mobile crushing, screening and scalping solutions for quarrying, recycling, contracting and mining applications. Our mobile units meet high demands for mobility both on site and on the road. Available on crawlers, they are compact, very stable and of low weight. Since the different units are compatible with each other, it is easy to combine two, three or more units, depending on the fractions required.

 

 

Grinding mill of production capacity influence factors

As we all know, the most common equipment, used to crush all kinds of ores into powder, is ball mill and raymond mill. The ball mill usually grinds the ores into powder through the ball and internal liner plate in the barrel, so it is a type of fine grinding equipment mainly applied in beneficiation and building material production, but its maximum grinding size is about 360 meshes.

Raymond mill is a type of powder making equipment mainly used in the industry. Raymond mill is suitable for grinding more than 280 kinds of raw material into powder, such as barite, calcite, potash feldspar, talc, marble, limestone, ceramics, glass and so on, whose Mohs hardness are not more than 7and humidity less than 6%. And these raw materials are used in non-explosive mining, chemical, building materials, metallurgy and other industries. In addition, the final product size can be easily adjusted within 100~425 meshes.

There are several main factors influencing the capacity of grinding mill (ball mill and raymond mill):

1. The first factor: the humidity of the raw material. If the raw material is too wet, it is easily adhered to the ball mill and raymond mill when they work, and the final products also are easily blocked when they are transported to the final product storehouse, which all reduce the powder making capacity.   2. The second factor: the hardness of the raw material. For the raw material, the harder it is, the more difficult to grind and the more serious damage of the equipment. When the mill speed slows, the capacity is surely smaller.

3. The third factor: the required mesh of the final products. The smaller required mesh of the final products, the smaller capacity of the mills.

4. The fourth factor: the composition of the raw material. Because some fine powder easily adheres to the mills when the raw material is transported, so if the raw material contains too much powder, the transportation will be influenced, so that the capacity will reduce. So it should be screened first for the raw material containing too much fine powder, before the raw material being grinded.

5. The fifth factor: the viscosity of the raw material. The bigger viscosity of the raw material, the more adhered of it.

6. The sixth factor: the spares or parts of the grinding mills, such as crusher hammers, jaw plates. The better wear-resistance of the parts,  the larger capacity of the mills.

As a whole, it is very important to find out the factors influencing the equipment capacity, so we can deal with these problems better. What’s more, among these factors, the second and third factor greatly influences the capacity. Because as we all know,  the harder ores, the more difficult to grind them into powder.
