End port, rail coal mismatch to gain India prize

The participants of South Africa's coal value chain needed to put an end to the misalignment of port over capacity and rail under capacity, Webber Wentzel mining partner Manus Booysen said on Monday.Booysen, just back from a major coal conference in New Delhi, called for coal value chain participants to meet urgently at the highest level to take full advantage of the colossal opportunity that was rapidly building up for the export of additional coal to an energy-hungry India.

Product Application

As everyone knows that MTW trapezium mill is an ideal machine for grinding barite, limestone, mica, talcum, quartz, calcite, granite, porcelain clay, basalt, gypsum, gold, iron ore, bauxite, copper, cement, coal etc. We believe it will play a huge role in powder making industry of construction, mining and paper-making and so on.

Product Advantage

  • All-in-one machine

    This kind of machine can form the closed production line with classifier products to create a variety of size of particles. And we can also increase the productivity of Ball Mill by 35%-40% before the ball mill.
  • Substantial usage efficiency of the wearing parts

    From top to the end of this grinding roller are evenly wearing , which have extended its service life.
  • Large crushing and thin powder ratio

    Equipped with the vibrating screen, this variety of MTW trapezium mill can grind the elements to thin supplies of less than 2mm or 1mm, which have increased the production of Raymond mill by 30%~40%.
  • Desulfurization of the power plant

    MTW trapezium mill can grind the calcium carbonates to the thin powder of less than 2mm or 1mm so that the desulfurization is improved.
  • Refractory block, unburned pieces

    The crushed products of MTW trapezium mill will be used to produce the particles such as refractory block, unburned pieces, etc. And that's have the superior match with the powder.

Operational Principle

Step with main shaft, bulk disk and roller bracket is driven by motor through reducer. Installed above bracket, roller assembly rotates with main shaft and swings freely meantime, this bring a large centrifugal force, which scatters bulk materials evenly in grinding intermediate layer between central roller and ring. The bulk products are grinded into powder and fall on the bottom, and then discharged from discharging opening under the impact of synchronously-rotating scraper.
