In Indonesia, coal transportation has traditionally been handled by trucks and by other mechanical means. With the expansion plan of coal production and increasing truck costs, Kayan Putra Utama Coal believes that alternative modes of transportation must be considered. For long distance transport of export size coal, one of the most viable options is to use coal slurry pipeline. This paper compares the technical issues involved in all coal pipeline options. Economic analysis compares the cost of transporting coal from the mines to ports by the best option of coal slurry pipeline or truck. On the basis of these comparisons, recommendations are made on how coal slurry pipeline can help in achieving proposed increased production targets and decreasing the operation’s export coal transportation costs.

What is Hydroseeding?
Hydroseeding is a method that can be used for planting grass for purposes of erosion control, or to grow new lawns entirely; it has been around since the 1950s. It is also an efficient, inexpensive alternative to laying sod in an area where grass or a lawn is desired. Hydroseeding can also be referred to as hydraulic mulch seeding, hydromulching, or hydroseeding. How does it work? The machine that actually does all the work for you is called a hydroseeder. Machines come in two main types: jet agitated and...
Bulk Bag System Design Considerations
Designing a new Bulk Bag Mix Tank Feed System? Here are some considerations during the design phase that will help meet expectations of plant managers and operators alike: Gravity feed of solution or metering pumps: Depending on the installation, solution/slurry from the mix tank can be gravity fed to process or if discharging into pressure, metering pumps will be required. Once you determine you need metering pumps their are different types. IPM doesnt manufatucre any pumps but has used various types over the...
Tailings paste disposal – more than water recovery
The minerals industry has faced increasing pressures in recent years in the management of tailings streams. Environmental, economic and other factors have led many minerals producers to explore the technology of making and using “paste.” With the increasing number of installations worldwide, this technology has proved to not only be industry accepted, but economically advantageous. The ability of paste thickeners to produce a higher concentration underflow leads to significant water recovery and...

Customer comparison of Rotomite-6000 to competitive products-case study
Crisafulli Sales Engineer`s field report (May 2003)The Rotomite-6000 was a pleasure to operate. We dredged bottom ash and silt. The Rotomite Cobra Cutterhead`s down pressure and articulation capabilities make the Rotomite-6000 effective against crusted sludge.The Customer had an unsatisfactory experience with a competitor`s dredge, which they had rented the prior year: the hydraulics were plumbed wrong on the competitor`s dredge and were not corrected for 3 weeks during which time they couldn`t dredge. When...
