The cement industry needs to grind a large amount of mineral material. How to reduce the crushing energy consumption, improve the output and quality, make the grinding process optimization, has been the cement industry research personnel's efforts direction. Ordinary pipe mill powder grinding cement, one is when the product than the table area of 340m2/kg, will produce paste segment and caking phenomenon, but the use of small size of the grinding body, because of the number of units, large specific surface area, the time of the impact of the grinding material in the number of times, cement particle size distribution curve steep, high strength Internal Grinding Machine
Powder grinding high fine cement will not occur cement condensation and caking phenomenon; second, because the material in the mill in various parts of different particle size mixed together is not conducive to different grinding bodies for crushing or grinding, resulting in high energy consumption, low output.Internal Grinding Machine
In recent years, the technology of grinding internal sieving for pipe Mill (also known as high yield and fine grinding internal reconstruction technique) has been reformed for the internal structure of the mill because it does not increase the power of equipment. It can increase production, reduce power consumption and improve the specific surface area of finished products. At the same time because of less investment, technical renovation time is short, so very popular.Internal Grinding Machine
The principle of grinding inner sieving technology is to replace the original compartment device by setting the sieving device in the ordinary pipe mill. The former storehouse material carries on the forced sieving, the interception big pellet, lets these big pellet still return to the ball storehouse to continue with the big size steel ball to break, the qualified fine material enters the storehouse. At the same time, according to the characteristics of the material itself, grain size, process conditions, each warehouse with suitable ball, section gradation, to control the average size of the material after entering the warehouse.Internal Grinding Machine
Fine grinding silo using large surface area of small size grinding body, greatly improve the grinding capacity of the mill, so as to obtain high yield, high specific surface area of the finished product, to maximize grinding efficiency.
The essence of the technology is to make the material in the mill with the corresponding size of the grinding body step by step grinding, and timely screening, so that the material in the case of low power consumption to grind into a finished product.Internal Grinding Machine
