Application of Bentonite Powder Equipment and its technical theory
The application of Bentonite Powder Equipment mainly has two aspects, one is for metal ore grinding, including coarse concentrate regrind, a section of grinding and three-stage grinding instead of ball mill, currently in copper, gold, lead and zinc mines. , platinum ore, iron ore and other aspects have a wide range of applications. The other is limestone grinding used in limestone ripening and flue gas desulfurization. At present, about 85% of Bentonite Powder Equipments are used in the regrind of coarse concentrates. It can be seen that the application of Bentonite Powder Equipments is a very mature process in the regrind loop of coarse concentrates. In recent years, with the increasing specifications of vertical mills and the emphasis on energy conservation and consumption reduction, Bentonite Powder Equipments are increasingly being used in a series of grinding and three-stage grinding.
The laminating pulverization of the Bentonite Powder Equipment means that a large number of particles are in a limited space and are brought together by a strong external force to contact and squeeze each other. As the pressure increases, the gap between the particles becomes smaller and smaller. When the compressive stress intensity transmitted between the particles reaches the crushing strength of the particles, the particles are broken, and the laminated pulverization can be roughly divided into the following three stages.
- 1. The compact phase. When the pressure in the vertical mill is small, the material particles are close to each other, squeezed tightly, and maintain good contact. At this time, the volume changes greatly and reaches a certain degree of compactness.
- 2. The crushing stage. As the pressure increases, the density increases continuously, and the gap between the particles becomes smaller and smaller until the particles can transmit the compressive stress to each other. When the stress intensity reaches the crushing strength of the particles, the pulverization process begins.
- 3. The stage of the formation. When the pressure reaches the top value in the above pulverization process, the pulverization probability reaches the top value. Since the crushing chamber becomes smaller and smaller, the broken small particles are agglomerated like a powder, and the material should be discharged quickly.
Lamination pulverization is carried out under pure pressure. When compared with simple pressure, impact force and shear force, the pure compressive stress has a better pulverizing effect than impact and shear.
