How about the recovery capacity of the dewatering screen in coal slime dewatering
The recovery and reuse of fine coal slime is a way to improve economic benefits for coal preparation plants, and the dehydration of fine coal slime can be treated by combining the vibrating dewatering screen with the plate and frame filter press.
1, Overview of characteristics of vibrating dewatering screen
According to the particle size composition characteristics of coal slime, the Xinxiang vibration screening machine manufacturer recommends that you use a vibration dewatering screen. The performance of this equipment in recovering the underflow of flotation tail coal concentrator is far better than that of sedimentation centrifugal dewatering machine. The main features are:
1. Use two sets of screen-type dry oil lubricating vibration exciters as vibration sources, and the two sets of vibration exciters are connected through universal couplings;
2. The screen box moves in a straight reciprocating motion with high frequency and high vibration intensity;
3. The fine particles are intercepted by the filter layer, and the fine particles are recovered and dehydrated by the large screen gap;
4. The screen surface is divided into three working areas: pre-dehydration, filter formation and filtration dehydration.
2, Effect of high frequency vibrating dewatering screen in fine coal slime dewatering
The main working process of the dewatering screen applied to fine slime is as follows: a part of the underflow of the tailings thickener enters the hydrocyclone for desliming and re-concentration; The bottom flow of the cyclone enters the dewatering screen; The screened material is mixed with the jig coal and sold; The screen water mixed with the overflow of the hydrocyclone enters the filter press or returns to the thickener;
The whole process uses clean water, which causes the system to add more water than the water taken away, and the coal slurry is discharged outside, so the coal slurry water cannot be closed; After transformation, the first stage of the desilter and the second stage of the desilter are de-mediated with circulating water, and the second stage of the desilter is de-mediated with recycled water. All cleaning and cleaning are done with recycled water, and the consumption of other clean water is strictly controlled;
It is stipulated that fresh water can be added only when the water level of the circulating water tank is low to a certain degree; When it is higher than a certain water level, it is not allowed to add fresh water to achieve zero discharge of coal slurry water; Now, the domestic water of our factory is also returned to the production system after being treated by the sewage treatment station, saving the amount of clean water, protecting the environment, and realizing clean production.
To sum up, the fine slime recovery and treatment system is reliable, which has solved the problem of insufficient filtration capacity, paved the way for the in-plant recovery of the slime plant, and has good economic and social benefits.
About Transportation
After you place the order and pay the deposit, we will start to arrange the production and contact the ocean freight transportation agency to reserve the position. Two days before the end of production, you need to complete the final payment. Then, we inform the ocean cargo transportation agent company that it is ready to come to the factory to pull the goods to the port. On the day of delivery, we will send the customer the factory video and pictures, and mark the corresponding English name of each product and product parts with a marker to prevent the customer from not knowing what each part is after receiving the goods. At the same time, we will put the English version of the product instructions in the cargo box. We generally select freight forwarders with preferential prices for customers to deliver goods for you. The shipping method can be FOB or CIF. You can also choose EXW, and then contact the goods agent company yourself.
