Product structure and principle:

Do you still worry about the annual use of thousands of tons of fine sand slime can not reasonably use it? Do you still have a headache for the high cost of fine sand slime recovery equipment? High-service fine sand, slime dewatering screen professional for you to solve the fine sand, slime recovery problems.

With the development of China's coal industry, coal washing rate increased year by year, as a coal washing process in the waste - slime, a large backlog, has become a major public hazard. According to statistics, China's existing sand washing, coal preparation plant annual production of nearly 10 million tons of sand, slime, and the utilization rate of only 30%.

So Jiedeng Mining Equipment Manufacturing Co., Ltd. design and production of fine sand, slime dewatering screen stand out, the machine is my company for the slurry material dehydration, disengagement, deslimatization of a screening equipment. Because of its screen trajectory similar to the straight line, also known as linear vibration dehydration sieve, and because it is often used coal preparation plant coal recovery, can also be called slime dewatering sieve.

Jiedeng fine sand slime dewatering sieve features:

(1) screen box trajectory as a straight line, the relative energy consumption less, high dehydration, installation and transfer convenience, easy to replace.

(2) high-speed coal slime dehydration sieve power unit has a common motor driven by the coupling exciter drive and vibration motor drive {smaller model) two forms.

(3) high-quality coal slime dehydration sieve surface with nylon, stainless steel and polyurethane and other materials, can be combined with the actual situation of materials and users to choose.

(4) Sieve surface V-type design, higher dehydration efficiency.

Prior to the coal preparation plant for the recovery of slime, the use of complex systems, high power consumption of the disk vacuum filter, one-time investment in expensive plate and frame filter press and sedimentation centrifuge and flocculant performance requirements, the use of Large belt extruder and so on. Overall investment, maintenance costs are high.

Now the use of dehydration plant design process behind, the use of a long time, low production efficiency, resulting in the production process in the frequent failure, resulting in system downtime and output of coal water content fluctuations exceeded, whirlpool can not be normal Running, affecting the effect of dehydration.

Jiedeng slime dewatering sieve Working principle:

High-quality coal slime dewatering screen using a two-electrode self-synchronization technology, general-purpose eccentric block, adjustable amplitude vibrator. Mainly by the screen box, exciter, support system and motor components. Through the tape joint drive two separate non-contact vibrator for synchronous reverse operation, the two sets of eccentricity generated by the centrifugal force along the vibration direction of the component superposition, reverse centrifugal offset, thus forming a single vibration along the vibration direction , So that the screen box for reciprocating linear motion. Sieve box sieve from the feed port to the outlet was negative angle installation, so that the liquid material in the sieve plate to do climbing movement, coupled with vibration, so as to achieve the effect of dehydration.

Slime dewatering screen to the coal preparation plant in the future production process is more reasonable, clean coal production, quality indicators to a new level plays a very important role for the coal preparation plant safety work has played a strong role in promoting, marking the Coal preparation plant quality of coal products has opened a new page.

The slime dewatering screen is an important equipment of the coal preparation plant production system. It plays a key role in the dehydration effect of the main product and the normal operation of the downstream production process. Its stable operation directly affects the production quality of the clean coal. High-frequency dehydration screen compared to other washing equipment is concerned, the biggest feature is the low cost of investment, high rate of return, according to an annual output of 10,000 tons of dry slime recommended that the annual value of 1.5 million yuan can produce!

First, the tailings dry row (dehydration sieve) sieve structure:

Tailings dry row of screens by the screen box, support device (base), motor rack, vibrator, universal shaft, tape coupling, motor and other components.

Second, tailings dry row (dehydration screen) Screen principle:

The feed tailings are fed evenly from the feed tank to the inlet of the sieve. First, about 1/3 of the moisture is removed at a level of 45 ° to install the drain sieve, and the combination of the sieve and the sieve Department of the emergence of the accumulation of materials, slime particles by gravity settlement, began to form a thin filter layer, filter layer and prevent the remaining particles through the screen, making the filter layer gradually thickening. Water can not be screened in the upper part of the filter layer to form a pool, because the filter layer is thin, water gradually in the strong movement gradually removed, due to high frequency and low amplitude vibration state, making the formation of filter tail More and more dense, to the discharge mouth, the material to form a cake, the tailings of water in addition to part of the removal from the screen surface, the rest due to capillary action surfaced in the material layer, due to the negative surface of the screen installation, Will overflow from the discharge port, the surface of the water will flow to the junction of the pool.

Third, the tailings dry row (dehydration screen) Screen technical characteristics:

1, high operating frequency, high vibration strength, low moisture content on the screen, the unit handling capacity is high, when used for tailings dehydration can get a higher solid recovery rate.

2, the use of self-synchronization principle, the motor through the tire coupling drive vibrator, simple structure, low noise.

3, the negative angle of the installation, to the dehydration section of the screen surface and the level of 45 degrees to install, increase the area of dehydration and promote the material as soon as possible to form a filter layer of dehydration.

4, in order to adapt to the different nature of different tailings, the sieve amplitude adjustable, the method is to adjust the main and vice eccentric block angle, so as to meet the different nature of tailings

Dehydration effect, make the best efforts to achieve the best process results.

5, side plate and beam connection using torsional shear type high strength bolts, no weld, to avoid the welding stress caused by the side plate cracking problem.

6, the vibrator for the block eccentric unit body structure, easy disassembly and maintenance.

7, bearing the use of vibration equipment for bearings, to avoid premature bearing damage.

8, the screen surface with polyurethane flexible screen surface, high opening rate and flexibility, is conducive to dehydration.

9, the screen side of the pressure plate are used polyurethane materials, long life, the screen surface fixed and reliable, and can effectively protect the screen frame side plate from the material erosion.

10, the screen surface with rail seat installation, can be very convenient for the screen surface maintenance and replacement.

11, the lower beam surface coated with anti-wear coating, to prevent premature wear and broken beam.

12, the use of steel coil spring vibration, the maximum reduction of the machine on the basis of the dynamic load.

13, using the finite element structure analysis software to ensure that the screen frame strength, stiffness and force is reasonable, and light weight, minimum energy consumption.

14, according to the user can be equipped with a chassis and feeding box structure, easy installation and commissioning.
