Cast stone is a material whose wear resistance and corrosion resistance are more than ten times, or even dozens of times, higher than those of steel plates, rubber, and lead plates. Cast stone is mainly used in chemical industry, metallurgy, electric power, building materials, construction, light industry coal, textile and other industrial fields, and is widely used as wear-resistant and corrosion-resistant materials. Cast stone powder is made by crushing and grinding crystallized cast stone. As a manufacturer of cast stone powder production equipment, the cast stone powder grinding mill produced by Guilin Hongcheng has been widely used in the production of cast stone powder projects. Today, I will introduce to you the method of producing cast stone powder with cast stone powder production equipment.

Application of cast stone powder production equipment: cast stone has rich resources, simple production process, low cost and excellent wear resistance and corrosion resistance. The main purpose of cast stone is to be used as anti-corrosion and wear-resistant materials in industry, such as anti-corrosion lining of acid and alkali storage tanks, reaction tanks, pickling pools (troughs), chutes for various ores, ash, tailings And conveying pipelines and wear-resistant linings of ball mills, etc. The main properties of cast stone are high hardness (Mohs hardness is 7-8, second only to diamond and corundum), good wear resistance (wear resistance coefficient is 0.09-0.14 g/cm2, 5-10 times higher than manganese steel , dozens of times higher than carbon steel), strong corrosion resistance, except for hydrofluoric acid and hot phosphoric acid, it can resist any acid and alkali corrosion (acid resistance is greater than 96%, alkali resistance is greater than 98%). On some parts of many equipment, cast stone is an ideal substitute material for steel, iron, lead, rubber, wood, etc. It has high wear resistance, acid and alkali corrosion resistance that ordinary metals cannot reach, and can prolong the service life of equipment. Reduce maintenance man-hours, improve production efficiency, reduce product costs and other advantages.
The production of cast stone powder uses natural rocks (basalt, diabase and other basic rocks and shale) or industrial waste slag (blast furnace slag, steel slag, copper slag, chromium slag, ferroalloy slag, etc.) as the main raw materials. Add certain additives such as horn-mesh rock, dolomite, fluorspar, etc., and crystallization agents such as chromite, titanite, etc., and make it through grinding, batching, melting, pouring, crystallization, annealing, and finished product grinding. The production of cast stone powder is to transform the multi-mineral phase raw material into a single "cast pyroxene" mineral phase through raw material melting, magma crystallization, and casting annealing, and at the same time have a suitable particle size (0.01-0.1mm) product. Only when plagioclase, common pyroxene, olivine, magnetite and other mineral phases are transformed into a single topyroxene, that is, a special pyroxene phase that can only be obtained under cast stone process conditions, can a suitable granularity. Under certain process conditions, when a suitable particle size is obtained, the transformation of the mineral phase is correspondingly completed.
During the production process of cast stone materials, a part of waste will be generated. Due to the high hardness of cast stone (about 8 on the Mohs scale), the traditional method is to scrap this part of waste. However, with the development of ultra-fine crushing technology, the industrial production of ultra-fine powder from cast stone material waste and crystals can be realized. The main process of producing cast stone powder is to grind this part of defective products through a mill. At present, cast stone superfine powder of about 1000 meshes can be produced. Cast stone powder can be used to make corrosion-resistant cement, and its corrosion resistance is more than 10 times that of acid-resistant cement. Cast stone powder mixed with cast stone sand and cast stone aggregate can be tamped into corrosion or wear-resistant concrete, and the application effect is particularly good.
The cast stone powder production equipment produced by Guilin Hongcheng includes Raymond mill, vertical mill, ultra-fine vertical mill and other types. The grinding fineness can be adjusted from 80 to 2500 mesh, and the corresponding model can be selected according to the output.
