raw bauxite grinding mill

bauxite processing plant, bauxite ore crushing and ore grinding equipment

As we know, bauxite ore is very hard, so it takes a longer time for crushing. In the bauxite processing, the Jaw Crusher is used in the coarse crushing, and Impact Crusher is used in the secondary, Cone Crusher is in fine crushing. Usually, according to the quarry conditions, mobile crushing plants are also used in the bauxite quarrying. Bauxite particles should be further grinded by the use of grinding mill. And the types of grinding mill are varied, including Ball Mill, LM series Vertical Shaft Mill, T130X Superfine Roller Mill, and Raymond Mill, etc. To get aluminium concentrate, it adopts the method of gravity separation, adopting a Spiral Classifier.

Bauxite is an aluminum-rich minerals, chemical or biochemical rock. The main mineral component is diaspore , boehmite, gibbsite. Alumina silicate minerals are weathering after intense heat. It will produce dissolved alumina, , moving into the sea from the lake basin sediments.

1. Raw material is fed into the burner via high temperature calcination, Part of material can also adopt drying method; 2. After being crushed by small jaw crusher, or hammer crusher, calcined bauxite will be fed into the mill; 3. After the crushed material enter the mill production systems, entire milling, separating and other operations processes are finished inside the mill automatically. The operating workers should take close notice on Electrical cabinet meter data; 4. Qualified bauxite powder will discharge via the discharge valve, then packing into bags;

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium. It contains a mixture of oxides like aluminium hydroxides, hydrous aluminium oxides, and minerals like gibbsite, boehmite and diaspore including some clay minerals. It also contains, insoluble materials namely magnetite, quartz, siderite, hematite and goethite. It is usually, yellow, white, beige, grey, reddish-brown, pink and brown in colour.

grinding aids

Due to the current economic crisis and the situation in progress in the construction and mining industries, producers have been obliged to take several measures in order to notably reduce costs. In light of this situation, JAS brought to the market a family of innovative grinding aids, adapted to the new requirements of cement and mining producers with excellent cost/benefit ratio underConcCareM & GAbrand names, formulated using alternative raw materials of better performance/cost to the traditional products available in the market. JASConcCareM and GAinnovative grinding additives concepts combined with specialized technical support, targeting improved production rates, enhanced strength development and adjusted workability contributes to the profitability of your business. TodayConcCareM & GAseries of grinding aids are in use in several cement, carbonate, phosphate, bauxite, ceramic, kaolin, silica and barite plants in many countries around the globe, generating excellent results with respect to their technical performance and the economic savings.

Grinding aids have been traditionally used to improve the efficiency of the cement maturation process which is considered as one of the most energy consuming processes in cement production (60 - 70% of the total electricity consumed in the plant). They are usually added at the entrance of the mill together with the feed.

The main function of a grinding aid is to partially neutralize the charges present on the surface of ore particles which are developed during milling, reducing the surface free energy of the material being grounded. Here, ConcCare GA100 series molecules are adsorbed over the surface of the ore particles by weak electrostatic forces, favoring the repulsion and/or a steric hindrance between particles, avoiding their agglomeration, and thus improving grinding efficiency. JAS ConcCare GA100 series are highly concentrated grinding aid formulated with selected raw materials to improve cement quality (early and/or ultimate strengths, flow) and to aid cement grinding, and accordingly increasing mill production.

JASConcCareM70series are superior grinding aids formulations specifically designed to improve bauxite grinding and therefore increase mill capacity.ConcCareM70product range can also help improve the handling and flow properties of moist bauxite. This technology offers significant financial and environmental benefits to the industry.

Alumina ConcCareM70series positively impacts the rheological property of bauxite slurry by reducing the viscosity and stickiness during the grinding process and therefore less energy is required. This less viscous slurry also requires less energy as it is easier to pump. The overall reduction in energy consumption ultimately results in reduced carbon emission to the atmosphere. ConcCareM70product range function by absorbing the free moisture content of the bauxite and agglomerating fine particles. The products can be applied at the mine site or during the unloading process to help prevent the buildup of bauxite on surfaces during the loading, unloading and reclaiming of bauxite.

Wet grinding of calcium carbonate is energy intensive.JAS ConcCareM80product range of polycarboxylate polymers-based grinding aids can help producers reach target particle sizes faster. Less grinding results in reduction of energy consumption and lower overall production costs.

ConcCareM80 of different molecular weights, termination agents, and different levels of neutralization offer the needed solutions to produce stable slurries for transport or process higher solids material requiring less energy for subsequent filtering and drying. Our in-house testing capabilities allow our R&D scientists to perform studies that help you choose the optimum product for your specific needs.

Grinding is a necessary process in phosphate rock milling using mechanical methods. The particle size changes due to the mechanical forces and chemical changes in the process reducing the surface free energy of the material being ground. In this case, theConcCareM50products molecules are adsorbed over the surface of the ore particles, favoring the repulsion and/or a steric hindrance between particles, avoiding their agglomeration, improving the dispersion and mobility within the mill and thus improving grinding efficiency.

JASConcCareM50range of phosphate grinding aids can effectively improve the production by 15-30%, improve fineness and accordingly reduce overall cost. In addition, a remarkable energy reduction will be achieved which results in reduced emissions due to burning less fuel.
