The Influence of Gravity Election in Mining Industry

The re-election of separation is dominated by some of the basic theory:
Settlement theory of particles and particle swarm;
Particle stratification theory according to population density;
Particles stratification theory in the rotary flow;
The stratification theory particles slant stream.
Settling theory of particles and particle swarm, it is to study the laws of particle sedimentation. The sedimentation of particles in a fluid medium is the most basic form of movement of mineral particles in the gravity separation process. Stokes studied the drag of spherical particles in a fluid movement, which laid the theoretical basis for re-election.
Free deposition of the particles in the medium:
The sedimentation of the individual particles in an infinite medium is called free sedimentation, which is the most simple form of sedimentation. Its state of motion is limited only by gravity and resistance, which is not interfered by the particles and the wall.
The essence of the re-election of loose mineral particles - layered - separation process. In the movement of the medium materials, the group of materials consist of different particle size and density of particles under the action of gravity, the fluid force, inertial force or other mechanical force loose, the loose mineral particles group, the difference between the state of motion due to settling, and form different density (or particle size) mineral particles. Through the medium, the materials achieve the separation of materials, and to obtain different final products.
The common equipment: magnetic separation, flotation machine, overflow-type ball mill, shaker, sand washing machine. The re-election of the theoretical study of the problem, simply put, it is to explore the relationship between scattered and layered. In fact, loosely layered and transporting separation almost occur at the same time. Loose stratification is the condition, and the stratification is the basis for separation.As the professional manufacturer of complete sets of mining machinery, such as clinker rotary kiln, Henan Hongxing is always doing the best in products and service.
