Mineral ore are the important material to extract metal elements or mineral elements. In the earth, there are many types of mineral ore. These mineral always exists in different rock or stone, we need use some ore crusher, ore grinding machines, and ore beneficiation machines to process them.

Mineral ore types

According to the structural state of minerals and ore content，ore deposit minerals can be divided into the ore mineral, ore-bearing minerals and minerals ore containing mineral three categories. Such as gold ore, iron ore, chrome ore, nickel ore, copper ore, cobalt ore, uranium ore and soon. So as to get high grade metal elements or mineral elements which are the important ingredient in modern industry. China Kefid is a leading company in china, we supply high quality mineral ore crushing and grinding equipments and design the suitable processing flow for global customer.

Mineral ore processing equipments

Mineral ore crushers are the important equipments in mineral processing, crusher can crush mineral ore to a suitable size which are adapt to the feeding size of grinding machines. In the mineral ore crushing process, raw ore will be sent to vibrating screen after primary crushing. The top products will be crushed again and then mixed with the middle products for together secondary crushing. The finished products are then screened out. After screening, the final products will be sent into ball mill ore Raymond mill for grinding. There can be secondary grinding according to products size.

As for ore crusher, customer can choose different types according to the types of the mineral hardness. There are gold ore crusher, iron ore crusher, chrome ore crusher, nickel ore crusher, copper ore crusher, cobalt ore crusher, etc. Customer usually choose jaw crusher for primary crushing equipment and cone crusher for secondary crushing while short head cone crusher is used for fine crushing. To increase production and equipment utilization factor, Ore beneficiation plant generally follows the principle of more crushing with less grinding to reduce the size of ore into the grinding mill.

Mineral ore grinding process plays an important role in mineral ore processing plant.  The mieral ore grinding mill grind the crushed ore minerals into fine even ultrafine powder so that the leaching and smelting process can go smoothly.

Mineral ore grinding mill can be divided into wet grinding type and dry grinding type. Because of these different applications, there will be open-circuit grinding and closed-circuit grinding process. Kefid Machinery can design different type of mineral ore grinding equipments for customers according to different requirement. The common ore mining machines are ball mill, raymond mill, vertical roller mill and MTW trapezium mill.

Mineral ore beneficiation process is also very important if customer need higher grade mineral. After crushing ore grinding, the mineral ore powder is fed into the SAG mill along with water, and then convoyed to ball mill for further grinding which reduces the mineral ore to slurry. The slurry fine enough passes through the trammel to primary hydrocyclone which uses centrifugal and gravitational forces to classify the rock particles according their size. It passes through the thickener to remove some of the water, and the moves into the leaching circuit.

Mineral ore processing flow design

Different mineral ore processing have different flow design. Kefid have our own engineer team, we can design suitable mineral ore processing plant for our customer.

Cement is an important construction materials, it has widely used in construction industry and plays an important role for the social and economic development. According the application, cement can be divided into cement and special cement. General, cement according to the the main water rigid material name is divided into portland cement, aluminum acid salt cement, aluminum sulfur acid salt cement, iron and aluminum acid salt cement, fluorine aluminum acid salt cement, phosphate cement etc.

Cement production process

In the cement manufacturing process, limestone, sand, shale, clay, and iron ore are used as main raw materials. The whole cement process in clued four stage: raw material crushing, calcination, cement grinding, packaging and distribution.

Raw material crushing

After the mining, most important raw material have big particle size and higher hardness, in oder get higher efficiency, most of the raw material need to crush to suitable size. Customer need use jaw crusher and impact crusher to crush them to suitable size which can meet next stage. Some time, customer also have to use ball mill or vertical mill, in order to get more thin powder. The raw materials are ground to a size where the majority of the materials are less than 75 microns. Materials exiting the mill are called “slurry” and have flowability characteristics. This slurry is pumped to blending tanks and homogenized to insure the chemical composition of the slurry is correct. Following the homogenization process, the slurry is stored in tanks until required. In the dry process, each raw material is proportioned to meet a desired chemical composition and fed to either a rotating ball mill or vertical roller mill. The raw materials are dried with waste process gases and ground to a size where the majority of the materials are less than 75 microns. The kiln feed is pneumatically blended to insure the chemical composition of the kiln feed is well homogenized and then stored in silos until required.

Calcination

The equipment is mainly has calcination clinker shaft kiln and rotary kiln two kinds, shaft kiln applicable to the production of small factory, big and medium-sized factory appropriate USES rotary kiln.

Raw material are complete preheating and precalcining in the cyclone preheater, next procedure is into the rotary kiln in the firing of clinker. In rotary kiln, carbonate further quickly decomposes and start a series of solid reaction, then form the important material in cement clinker. As the material temperature close, mineral will become liquid, dissolved in the liquid phase reactions and form a (clinker). Clinker firing, temperature began to drop. Finally, cement clinker cooling machine will cool the rotary kiln of high temperature clinker to a temperature which downstream conveying, storage tanks and cement machine could bear. At the same time, recovery afterheat of the high temperature clinker, so as to improve the system of the thermal efficiency and quality of materials.

Cement regrinding

After calcination, the cement clinker need to regrind to final cement products. Fineness of the final products, amount of gypsum added, and the amount of process additions added are all varied to develop a desired performance in each of the final cement products.

Packaging and distribution

Each cement product is stored in an individual bulk silo. Then bulk cement can be distributed to customer site by truck, rail, or water.
