Magnesia chrome brick, also called silicate bonded magnesia chrome brick, is made of sintered magnesia clinker and refractory chrome brick. The refractory grains are bound by silicate. The chromium oxide content of chrome ore used for producing magnesia chrome bricks is generally over 33%
The production process of magnesia chrome brick is simple and the price is low. The magnesia chrome brick is commonly applied in cement rotary kiln, lime kiln, open hearth furnace, external refining furnace, non-ferrous metallurgy furnace, metal mixer furnace, glass kiln heat storage room, electric furnace roof, refining ladle permanent layer, refractory kiln lining, steel-making lining etc
In common magnesite-chrome brick, the MgO content is more than 55%, but less than 80%, while the Cr2O3 content is no less than 8%. The main minerals in common magnesite-chrome brick are periclase and picotite, and the silicate phase is forsterite and calcium magnesium olivine
Silicate matrix in alkaline brick has the lowest melting point and can be easily eroded. All kinds of slag may react with it, which has the great influence on the performance of magnesia chrome brick. The way to improve magnesia chrome brick quality is to adopt compact and dense coarse-grained chromite with little calcium oxide in order to avoid external expansion. The other way is to reduce the low melting point of silicate brick, such as silicate manganolite and calcium and magnesium olivine to adjust the matrix and form a high melting point forsterite, increasing the density of the bricks and reducing the infiltration of slag
The ability of alkaline slag resistance of common magnesite-chrome brick is strong and the resistance to acid slag is better than that of magnesia brick. The load softening point of magnesia-chrome is high, the volume stability is good at high temperature and the shrinkage of the refired line at 1500℃ is small. The common magnesia-chrome brick is widely used in the firing zone of the rotary kiln
The mining industry in Zimbabwe is a significant contributor to the country's economy. The mining industry in Zimbabwe accounts for over 60% of exports in the country. Having a terrain that is quite similar to Australia and Canada, the country is a producer of many minerals and metals. Zimbabwe is particularly known for its resources of platinum group of mineralsas well as nickel, gold, diamonds and others
Zimbabwe’s mining industry is focused on a diverse range of small to medium mining operations. The most important minerals produced by Zimbabwe include gold, asbestos, chromite, coal and base metals. The mining industry contributes approximately 8% towards the country’s GDP
The first step of the mining and mineral processing operations is to remove the mineral value in ore from the host rock or matrix. Minerals may be extracted from the earth using a variety of techniques. Most extraction processes result in the removal of ore and associated rock or matrix in bulkform from the deposit, using blasting and crushing operations to break the ore into pieces of manageable size or to separate the ore minerals from unwanted material
Mining operation involves many different types of machines. As referred, there are many small and medium mining operations in Zimbabwe; mining technology is still in developing. It requires high technology and quality mining equipment to develop mining industry in Zimbabwe. Crusher machine is one of integral equipment in mining industry. SBM provides high performance and low price crusher for mining industry in Zimbabwe
Different scale of mining operations has various investment capacities and requires different types of mining machines.In mining operation, crushing is the first the integral operation, the layout of mineral crushing plants is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum
There are many factors to be considered for designing a reasonable crushing plant, such as ore characteristics, mineral deposit location, climatic conditions, expected operational life, safety, environment, and operability and maintainability. There are three main steps in designing a good crushing plant: process design, equipment selection, and layout
