Magnesium-chromium refractory mortar production equipment and method thereof

Abstract

The invention discloses magnesium-chromium refractory mortar production equipment and a method thereof. The magnesium-chromium refractory mortar production equipment comprises a crushing box, a powdergrinding box and a stirring box. The crushing box and the stirring box are separately located on two sides of the powder grinding box. A conveying cylinder is arranged between the crushing box and the powder grinding box, an exhaust column is connected between the powder grinding box and the stirring box, a static jaw plate is fixedly installed at the position, close to one side, of inside of thecrushing box, a dynamic jaw plate is arranged at the position, close to the other side, of inside of the crushing box, an eccentric shaft is connected to the top of the dynamic jaw plate in a penetrating mode, the end position of the eccentric shaft is connected with a belt pulley, a supporting plate is fixedly installed at the bottom of the crushing box, a driving motor is supported on the uppersurface of the supporting plate, and a transmission belt is connected between the driving motor and the belt pulley. The magnesium-chromium refractory mortar production equipment and the method thereof can prevent the accumulation of powdered chromium sand at the bottom of the powder grinding box, and can control the discharging speed of a discharging pipe.

Description

technical field [0001] The invention relates to the field of equipment related to the production of refractory mud, in particular to a production equipment and method for magnesia-chrome refractory mud. Background technique [0002] Chromium refractories are made of dead burnt magnesia and chrome ore as raw materials, but a kind of refractories with more magnesia content can be fired bricks, unfired bricks and fused cast products. The main crystal phase is periclase and Spinel, the matrix is ​​mainly composed of forsterite, forsterite and rhodonite, etc. If the impurity content is low, the amount of silicate between periclase and spinel particles is very small, and it is combined by solid phase sintering The bricks are called directly bonded bricks, which need to be fired at high temperature and have good performance. Magnesia-chromium refractory materials have high high-temperature strength, slag resistance, thermal shock stability and volume stability. They can be used in ...

[0002] Chromium refractories are made of dead burnt magnesia and chrome ore as raw materials, but a kind of refractories with more magnesia content can be fired bricks, unfired bricks and fused cast products. The main crystal phase is periclase and Spinel, the matrix is ​​mainly composed of forsterite, forsterite and rhodonite, etc. If the impurity content is low, the amount of silicate between periclase and spinel particles is very small, and it is combined by solid phase sintering The bricks are called directly bonded bricks, which need to be fired at high temperature and have good performance. Magnesia-chromium refractory materials have high high-temperature strength, slag resistance, thermal shock stability and volume stability. They can be used in electric furnaces, converters, As an important part of refining equipment outside the furnace, non-ferrous smelting furnace and cement rotary kiln, magnesia-chrome refractory mud production equipment is a common equipment for producing refractory mud; but when the existing magnesia-chrome refractory mud production equipment is in use, the powder Chromium sand is easy to accumulate at the bottom of the milling box, and it is inconvenient to control the discharge speed of the discharge pipe
