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;
Raymond mill is ever one classic powder grinding machine in the past. And most of modern mill are from it and MTM series milling machine is the most successful one. It optimized the inner structure and lots of core devices. Such as, the new supercharging device can greatly increase production capacity. And separated ploughs are easy to be replaced, both the spare parts cost and breakdown time are obviously reduced. According to hundreds of customers feedback, the MTM series grinding mills are quite good at produce 60-325mesh powders. Through word-of-mouth, this milling machine is quite hot in many countries.
After the grinding roller and rings are worn to a certain degree, by adjusting the length of the compression spring, can a constant grinding pressure be maintained between the grinding roller and the grinding rings, which increases the utilization rate of the roller ring, saves the material costs and the production is kept stable.
The grinding roller assemblies are connected by means of the horizontal tie rods and springs, with the radial force applied to protect the main shaft and bearings against the impact from large-sized materials in the grinding chamber, so as to prolong the service life of the equipment. The combined action of the high-pressure spring and centrifugal force ensures a tight contact between the grinding roller and ring. The rolling force is 1.2 times higher than that of the Raymond mills in the same conditions, so the capacity is greatly improved.
The main mill and powder classifier are combined by braid connection. The damping springs and sealing tapes are used to reduce the vibration and noise and also avoid resonance.
The host drives the central shaft running (Fig. 3) by the gear box. The upper end of the shaft is connected with a wobbler spindle and the grinding roller is suspended under the wobble spindle by a cross arm shaft and forms a swinging point. The grinding roller runs along with the central shaft of the whole machine, and also rotates by friction with the grinding ring. A perching knife system is installed under the wobble spindle and feeds the material into the gap between the grinding roller and ring for pressing and grinding with the grinding roller during rotation. (Fig. 5) Air flow will bring minor powder into the powder concentrator upon entry into the grinding gravity from the bottom of the grinding ring. Coarse materials fall down and are reground; and fine powder goes into the powder collector along with the air flow and is discharged as the finished product through the powder discharge tube.
Since 1969, Britain, Germany and other developed countries have begun to process the superfine slag powder used as the application of mineral admixtures in concrete. It was in the 1999s that our country began to reach on the application of the superfine slag powder and after twenty years of development, slag powder has become a new independent new product, which is widely accepted and used in concrete configuration that can improve the compressive strength of concrete, reduce the concrete cost, but also improve the anti permeability and anti erosion ability Therefore, it will be widely accepted and used immediately as soon as the powder is produced.
The mineral powder is the high fineness powder that obtained by drying, grinding from water quenched blast furnace slag, which is high quality admixture of concrete and cement and it is important raw material that used for high performance concrete production in the world. The production of slag powder can not do without grinding mill. LM slag vertical grinding mill is professional slag grinding equipment designed according to the characteristics of slag. It adopts that the roller can grind material on the transmission arm directly, meanwhile the roller do not contact directly with transmission arm. This design has improved milling efficiency, reduced energy consumption, on the other hand, reducing wear and the cost of production. It has complete functions, which meet well the customer crushing, drying, grinding, and grading conveying production needs. And we can say that it save a large amount of investment, time and energy for clients.
If you want to build a complete powder production system, our authority engineers will design the most efficient, the minimum input, and maximum return for your powder production line. At the same time, in order to facilitate customer service, we have set up dozens of offices at home and abroad, and have established a perfect after sale service system; we also provide a variety of machine accessories to reduce the client loss duce to machine stopping working. Maybe our LM vertical mill price in the market is not the lowest, but our overall cost- performance ratio is the highest, because we pay more attention to the quality of the equipment, technology introduction, product development, quality materials, fine craft- This is Shi Bang machinery (SBM)Co,.ltd. that concentrates on the mining equipment manufacturer.
