TAPP Group Dewatering unit

TAPP Group Dewatering Unit costs 240-500 KUSD. The cost of ownership amounts to no more than 1 million rubles per year.

Compared to precipitation centrifuges, the unit does not stop due to overloading due to the increase of the fines content in the feedstock. Moisture content after the dewatering amounts to 12-14%, the sedimentation centrifuges produce 16-25% for the same types of coal.

Five TAPP Group dewatering units are now in operation at two facilities in Russia.

At Severstal's coking coals, the moisture content of coal concentrate was reduced from 18-20% to 13-14% using the latest dewatering equipment, eliminating a bottleneck in the process, which was in the drying section. This resulted in the company increased monthly output from 530 to 820 thousand tons.

The second project was implemented at EVRAZ using the largest dewatering screens in Russia 3x4.8 m and a capacity of 120 tons per hour. The moisture content of the concentrate decreased from 25% to 12%. Each of the electric dryers is now operating at new capacity, saving up to 400 kW of electricity per hour and allowing for more material to be processed volumes.

Each beneficiation plant requires concentrate dewatering to achieve the lowest possible moisture content.

TAPP Group dewatering complexes are the optimal equipment for dewatering operations at industrial facilities.

All weld joins are non-destructively inspected for compliance with DIN EN ISO 5817 weld quality standards before blasting and painting.

Quality standards

Base material

In the manufacture of each unit and supporting elements of the screen, shipbuilding steels are used with a set of mechanical properties that ensure reliable and long-term operation under conditions of vibration loads and uneven material feed.

This is the next stage in the development of coal dewatering equipment. It's productive, efficient, no-cost equipment that opens the doors to the future!

INCORPORATING EQUIPMENT INTO THE PROCESS FLOW

We take out arc sieves;

Set up a dewatering unit;

We dewater the centrate from the plant on sedimentation centrifuges to 10 microns.

In the dewatering of beneficiation products, especially fine grades and sludge, it's the screen oscillation frequency that is crucial for more efficiency. According to engineers' research, the best coal dewatering results are achieved at a fairly high acceleration of 20 G. This is when the capillaries between the grains of the material are most intensively broken, from which large amounts of moisture are released.

Dewatering screens operate at an acceleration of up to 20 G at which they are most effective in dewatering beneficiation products. In addition, they have an optimal and reliable design which makes them simple and easy to operate. All this makes dewatering screens the best solution for concentrate dewatering.

Dewatering screen

Best dehydration performance in its class!

The lateral positioning of the actuator contributes to convenient, fast and safe maintenance. The top cover hatch allows a quick inspection of the basket condition.

Capacity - 100 t/hour.

Optimal arrangement of the centrifuge feed assembly allows 100% of the basket's working surface to be used for dewatering!

Our centrifuges use only the best components from the world's largest manufacturers: 10 HF basket, American TECO motors, Swedish SKF bearings and German Optibelt belts. Competitors select cheaper analogs for their products, which affects the service life of structures, units and the centrifuge as a whole.

The centrifuge housing linings are made of high-strength ceramic tiles consisting of 42 elements mixed in precise proportions. The centrate part of our centrifuges is lined with spherical ceramic. The tiles used for centrifuge housing liners are the same as those used in our heavy-medium hydrocyclones.

Using our equipment means less time for scheduled maintenance. Reduced downtime, assemblies and parts do not require extra attention and are pain-free.

Changing centrifuge liners is a very time consuming and costly process, requiring 30 hours of shutdown. According to approximate calculations, running a centrifuge with cheap liners for 3 years costs your company the value of the complete centrifuge housing.

Vibration isolation frame is necessary to reduce the dynamic load on the building steel structures, reduce the destructive force, ensure safety and comfort at work. If employees are uncomfortable in the enterprise, they will tend to leave it as soon as possible, and consequently will perform their duties less diligently.

Vibration isolation frame

The frame reduces the damaging effects of vibrations on building structures;

Reduces dynamic loads transmitted by the screen by at least 98%;

The frame reduces the adverse vibration impact on the operating personnel.
