What equipment does the white gray processing line need?

What equipment does the white gray processing line need? White gray is the content of calcium oxide (CaO) and magnesium oxide (MgO) contained in white ash. The two substances play a decisive role in the strength of the two-gray gravel base, especially after the hydration reaction of fly ash, has a significant effect on which the content is significant, and a certain amount of increased lime dose can naturally improve.

The strength of the two gray gravel, but this not only increases the construction cost, but also is also very disadvantageous to increase the crack resistance of the two gray gravel base.

Limestone has a long history of exploitation as an important building, and the limestone is the main plant, lime and stones. Raw materials, is an indispensable flux rock in the metallurgical industry. After limestone is powdered, it is widely used in paper, rubber, paint, paint, medicine, cosmetics, feed, sealed, bonding, polishing and other products.

The first is the crushing of the object or the crush of the stone is mainly crushed by the crusher, and the bulk stone is broken into a stone having a certain size. These stones are then invested in the ball mill to carry out the powder grinding into the powder, and the lime rotary kiln will be calcined.

After all, the mass of material is not only improved in the difficulty of calcination, but also calcined enough to completely. Perhaps the surface roast is more serious but the interior is not calcined. Therefore, the material of the small piece or a powdery material is conducive to calcination. Physical reactions and chemical reactions occur in lime rotary kiln equipment.

Qualified limestone is stored in the silo, lifting the hoist and runs into the top silo of the preheater. The top silicon of the preheater is controlled by the upper and lower binders, and then the limestone is evenly distributed into each chamber of the preheater by the lower tube.

Limestone is 1150 \u0026 amp; Deg; C kiln smother in the preheater to 900 \u0026 amp; deg; C, about 30 % Decomposition, the hydraulic push rod is pushed into the rotary kiln, and the limestone is broken down into CaO and CO2 in the rotary kiln. The limestone generated after the decomposition enters the cooler, and the cold air is cooled to 100 \u0026 amp; Deg; C is discharged in the cooler. The heat exchanged 600 \u0026 amp; deg; C hot air enters the kiln and gas mixed combustion. The exhaust gas enters the bag dust collector in the air insulation of the cold wind, and then enter the chimney through the exhaust fan.

The production line of the same capacity is configured by different manufacturers. The manufacturer has some differences in the production line equipment configured by the user, and the nature of different manufacturers is different. The total cost of the manufacturer is equipped with a production line.

Built a limestone abrasive production line In addition to the cost of putting costs on the equipment, it also needs to put a certain fee in the ground lease, documents, and the purchase of raw materials, and their cost is How much, to combine local prices and selected raw materials.

Selecting a reasonable crushing device and the milling machine device, it is important to process the particle size of the material before the material enters the abrasive device. The size of the size, uniform particle size, so that the mill is reduced to reduce the abrasive load and improve the yield of the mill.
