Coal Preparation and Enrichment Plants

TURN-KEY COAL PREPARATION AND ENRICHMENT PLANTS

The Daniels Company is one of the most well-known and experienced companies worldwide in the design, supply and installation of high capacity coal preparation and coal washing plants. Since its founding in 1956, it has established more than 800 coal plants around the world. Its market share in the Chinese coal preparation industry has reached 70%. The company, which offers a 3-product cyclone-centered solution with its innovative process design, has disabled many equipment and provided serious initial investment and operational advantages.


INNOVATIVE PROCESS DESIGN


ANAHTAR TESLİM KÖMÜR HAZIRLAMA VE KÖMÜR YIKAMA TESİSLERİ

3 PRODUCT CYCLONE HIGHLIGHTS

  • Single unit has a capacity of up to 10 million tons/year.

  • In the conventional system, the separation made in two stages is carried out in a single unit.

  • It can provide higher performance in separation with a wider grain size.

  • The circuit required to wash fine coal is eliminated.

  • Design variants are more flexible and provide flexibility for feeds with different washability.

  • The second stage density goes up to 2.2 kg/l.


3 ÜRÜN SİKLONU

ADVANTAGES OF GRAVITY FEEDING

  • The use of pumps causes the coal to crumble and break.

  • Low number of pumps in the facility, pump wear in conventional facilities, etc. maintenance costs are eliminated.

  • Wear on cyclone linings is reduced and provides longer service time.


GRAVİTE İLE BESLEME AVANTAJLARI

DIRECT FEED ADVANTAGES

  • There is no need for screens, cyclones and pumps.

  • There is no need for a separate process for fine coal.

  • The slime discharge and sieving process increases secondary slime production by up to 20%.

  • It does not disrupt the rheology and stability of the coal fine medium suspension in three-product cyclones.


DOĞRUDAN BESLEME AVANTAJLARI

PERFORMANCE ADVANTAGES

Compared to Coarse Grain;

  • The difference between separation density and ambient density is low. (<0.15kg/l)

  • Since its stopping time is high, its performance is high.

Compared to Fine Grain;

  • It is more efficient than hydraulic systems.

  • There is no need for an ultra-thin magnetite system.

  • The cutting intensity shift is lower.

3 Product Cyclones;

  • up to 0.25mm size,

  • With "Fine Coal Heavy Media Cyclones", a high performance separation of 0.1mm size can be achieved.

PERFORMANS AVANTAJLARI

PROCESS ADVANTAGES

  • Investment & Operating Costs: Compared to conventional systems, facility investment and operating costs are around 20% lower.

  • Profitability: Higher amounts of clean coal and intermediate products can be produced than conventional systems.

  • Environmentally Friendly: Thanks to dewatering technologies, they are completely closed circuit, environmentally friendly processes that do not require waste dams where all the water is recycled.

  • Reliability: It has been installed more than 800 times in the world and has proven its reliability many times.

  • Convenience: With only 3 product cyclones, you can create multiple levels of tubs, baths, cyclones, spirals, etc. It makes the flow chart quite simple by replacing it.

  • The process and system are simplified thanks to the superior engineering at its core; Although it has a simple flow chart, it has been perfected over the years with the optimization of fluid dynamics, rheology parameters and facility design, and a patent-protected "know-how" has been revealed. Therefore, Daniels is a system technology provider, not an equipment supplier. With this know-how, more than 800 facilities have been established and these facilities currently produce approximately 1 billion tons of coal per year.

  • In China, three product cyclone have been imitated but have failed applications. This is because, in addition to the issues mentioned above, the inventor of the three-product cyclone technology is The Daniels.
