Coal Spiral Quality

Coal - Mineral Technologies

In the USA we’ve installed over 1,000 coal spiral starts and treat in excess of 18,000,000 tonnes of coal annually across the region. New Low Cut Point Coal Spiral In July 2014 we launched the new LC3 Spiral which significantly improves coal quality. Coal Handling and Preparation Plant (CHPP) Design

Weve Improved Coal Quality - New LC3 Low Cut Point Spiral

Hey, despite knowing that it was going to be really challenging, and several attempts had failed in the past, we knew our customers wanted better coal quality so we developed the LC3, a low cut point coal spiral – cuts down to 1.50, 1.45 and below!

KREBS® Coal Spirals for fine coal cleaning - FLSmidth

Spiral coal concentrators use the specific gravity of materials with different densities to separate coal, and produce a low-ash coal product at high efficiency. Our high-performance Coal Spirals deliver a feed capacity of 2 STPH to 3 STPH (1.8 mtph to 2.7 mtph) per start, dependent on raw coal quality and refuse amount to be discarded.

Operating guidelines for coal spiral circuits | Request PDF

As a result, coal spiral yield and product quality suffer when feed quality or feed solid content changes in a coal preparation plant. While such changes are not minute-by-minute; hourly,...

Coal Spiral Concentrators | Multotec

The spiral models each have different combinations and have been developed to suit the coal quality. New research and development has shown that our compact, modular designs have added flexibility when building or replacing spiral plants. This results in processing solutions that extend the life of your plant and reduce overall maintenance costs.

Spiral separator - Wikipedia

A spiral separator may process a couple tons per hour of ore, per flight, and multiple flights may be stacked in the same space as one, to improve capacity. Dry Spiral Separators. Dry spiral separators, capable of distinguishing round particles from …

Coal preparation plant - Wikipedia

Fine coal is cleaned using froth flotation methods. Denver cells and Jameson Cells are two flotation methods used. Spirals perform a simple, low cost and reasonably efficient separation of finer sized material, based on particle density and size. Dewatering


Water-only cyclones provide a low density cut but tend to lose coal. Spirals tend to ensure 100% coal recovery but have a high density cut. Combining the two units provides an efficient low density separation. Low pressure water injection at the bottom of the separation chamber fluidizes the high-density particles.

Gravity Spiral Concentrator Working Principle

The Humphreys Spiral has been successfully applied to recovery of chromite from chrome sands, rutile, ilmenite, and zircon from sand deposits, tantalum minerals and lepidolite from their ores, gravity concentration of base metal ores and in the cleaning of fine coal. How it works: Pulp is introduced at the top of the spiral and flows downward.

(PDF) Performance Improvement of a Compound Spiral

Spirals are capable of providing excellent clean coal recovery, although at a relatively high ash content. Like any other water-only separation process, spirals are also susceptible to fluctuating...

Coal Washing Plant -

Coal Washing Plant. The calculation of the performance of coal washing units that are in common use is not difficult and the principles of making such calculations have been known for many years. The flowsheets to be simulated consist primarily of coal washing units each with a target specific gravity of separation specified for each washing unit.
