Bauxite Production line
Bauxite ore processing plant (crushing and grinding process)
The raw bauxite ore is crushed to 100mm before stockpiling with Jaw Crusher, Impact Crusher even Cone Crusher. After this process, the ore will be dried from an average 12.5% moisture to 6.7% for shipping.
After the caprock layer has been broken by blasting or ripping. The bauxite will be mined and transported by belt conveyor. The average thickness of the mined bauxite is about 4m to 10m. An excavator or loader is used to load the bauxite onto haul trucks for transport to the bauxite processing plant. There is a very important procedure before extracting bauxite from bauxite mine that is bauxite crushing process and bauxite grinding process.
Crushing process is an important process in the whole bauxite ore processing plant. The crushing plant is made up of a number of components that include Vibrating Screen, crusher machine and Ball Mill. SBM Jaw Crusher as bauxite ore primary crusher. There are both double-toggle Jaw Crusher and single-toggle Jaw Crusher.
For the secondary crushing process of bauxite ore, you can choose Cone Crusher or Impact Crusher. What's different 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.We can get bauxite during vibrating table- recovery of bauxite in dross.This can solution the waste.
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. After grinded by ball mill, materials can be of standard sized between 0.074 mm and 0.4 mm in diameter. Aside from general mining grinding such as cement grinding, coal mill and ore grinders, SBM ball mill is also popular for any stone quarry operations.
Bauxite washing process
Bauxite washing process is used common after bauxite crushing process and bauxite grinding stage in bauxite crushing plants or bauxite quarry plants. Bauxite washing machine is similar with sand washing machine which is widely used in gravel pits, mining, building materials, transportation, chemical industry, water utilities, concrete mixing stations and other industries in the washing of the material.
Bauxite mining equipments
The bauxite mining process is complicated process and need many Bauxite mining equipment. Through the Bauxite mining process bauxite boulders are turned into all sizes of materials. The blasting process is the first step determining what needs to be accomplished next. Rock hammers, drop balls, primary crushers, and gyratory crushers all contribute to the bauxite mining process. Coarse materials are sent by belt conveyer to the bauxite crushing plant or bauxite grinding plant for additional crushing, grinding and sizing. The mine stockpiles different sizes of bauxite materials for their customers.
Introduction of Bauxite
Bauxite is an aluminium ore and is the main source of aluminium. Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts. The principal aluminum hydroxide minerals found in varying proportions with bauxites are gibbsite and the polymorphs boehmite and diaspore.
According to its capacity, the aluminum production line divided into small-scale processing plant and mass processing plant.
