Selection and application of curved screen

It is generally used for wet grading, dewatering, and dematerialization of heavy medium dressing . The utility model has the advantages of simple structure, light weight, small occupation area, no moving parts, large processing capacity, high separation precision, and meshing holes are not easy to be blocked, but the product on the screen has high moisture, the screen strip wears fast, the ore requirement is uniform and a certain pressure is required. The relationship between the size of the curved sieve mesh and the calculated particle size of the undersize product is shown in the table below.

Calculation of the amount of curved screen processing
q=160φAυ (1)
Where q - the amount of curved sieve treatment, m 3 / h;
A - screen area, m 3 ;
Φ——the effective area coefficient of the screen, generally taking φ=0.3~0.4;
υ——The feed rate of the slurry, when the slurry is fed in, υ=0.3~3m/s; when the slurry is pumped in, the υ can reach 6m/s.
The curved screen can also be used to calculate the throughput per unit area.

Where q 0 - the amount of processing per unit area of ​​the curved screen, m 3 / (m 2 · h);
D——mesh size, mm.

Kiln For Gold Extraction

The device has the following characteristics:

1.Wide application field: the device can regenate various types of activated carbonon by adjusting the angle and rotational speed of furnace pipe.

2.Regeneration activated carbon in the oven retention time 40 minutes, which is applicable to the regeneration levelofall kinds of grain particles, for coal activated carbon also has good regeneration effect.

3.High degree of automation:the device operation achieves automatic control,with man-machine interface+Intelligent instrument control,reduces the operating workers and the labor intensity is low.

4.High recovery rate of Iodine value:basically returned to a new carbon levels above 90%.

5.Low carbon loss:≤1-2%(Coal carbon)But slightly higher than the JHR-O series activated carbon fuel diesel reclamation equipment

6.Easy installation, covers an area slightly larger, but the small space height requirements, large installed power.

Long service life:The core components furnace tube using thick wall (10 mm thick) 1200 ℃ high temperature resistance, corrosion resistant special stainless steel pipe.
