When the beneficiation equipment is applied to physical beneficiation, it is a process of dissociating the crystal or changing from a large particle to a small particle because of the uneven hardness and particle size distribution and the need for physical and mechanical action. Therefore, for this beneficiation environment, the traditional application of particle size mineralization is still very extensive. Mainly because the control of particle size has become a standard measure of finished products. This mode of performance is especially evident in sand and gravel products. The particle size of the finished product directly determines the quality of the product. Then, in the particle size beneficiation method, what are the most widely used products? " Among them, the ore dressing equipment involved in the particle size selection mainly includes crushers , sand making machines , ball mills , classifiers, cyclones, etc. These devices are mainly Do physical operations, and have a clear relationship with the ore particle size, within a certain range determines the success or failure of the beneficiation process using the particle size beneficiation method.
Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells or wellbore.
It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow
drilling fluid to circulate and extraction to take place
The oil casing is a steel pipe used to support the well wall of oil and gas wells to ensure the normal operation of the whole well during drilling and after well completion. Several layers of casing shall be used for each well according to different drilling depth and geological conditions. Cement shall be used for cementing after casing is put into the well. It is different from TUBING and drill pipe and cannot be reused. It is a disposable consumable material. Therefore, casing consumption accounts for more than 70% of all oil well pipes.

Surface casing
- Protects the well from contamination in shallow water and gas layers.
- Supports the wellhead equipment and sustains the weight of the other layers of casing.
Intermediate casing
- Isolates different layers of pressure to facilitate normal circulation of drilling fluid and protect the production casing.
- Intermediate casing facilitates the installation of blow-out preventers, anti-leakage devices and tailpipes in the well.
Production casing (oil string)
- It is the conduit through which oil and gas pass from a below surface reservoir.
- It protects the well and separates fluids into various layers.
First, green pipes are threaded on each end. The threading is then inspected and, if necessary, rethreaded to ensure that the thread accurately connects to the coupling. The threading type includes STC/BTC/LTC. The casing pipes are strengthened by surface treatment and are subject to various inspections, including drifting and hydrostatic tests before they are coated and packaged into casing.
Casing pipes are ordinarily produced with outside diameter sizes of 114.3 mm to 508.0 mm.

The current beneficiation methods mainly targeted by the beneficiation equipment can be roughly divided into two different principles, one is the physical form of the beneficiation method, and the other is the chemical form of the beneficiation method with higher precision requirements. The physical beneficiation includes magnetic separation method, re-election method, electrostatic beneficiation method, friction beneficiation method, particle size beneficiation method, shape beneficiation method, hand selection method, etc., and chemical beneficiation includes flotation method, roasting method, and leaching method.
