Dear Mr. Mohan Babu,

Irrespective of which drying technology you use, you will surely benefit from online moisture analysis. Our Australian Principal CALLIDAN is the world leader in Online Moisture Analysis and manufactures and markets online moisture analysers that use microwave technology. Please feel free to visit our principal's site at www.callidan.com for more information. Regards

A vibratory fluidbed dryer would work well in your application.

Not only do they use less energy than other drying options, but are totally enclosed and can be custom designed to fit into your current process.

Thank you,

With energy prices set to rise over the next 5 years, we know this system will be of great interest to you, either as a pre-dryer for your existing drying systems or as a standalone drying, pumping or material handling unit.

The key Points associated with this unique environmental system, compared to any known rotary, ventura, vibrating fluid bed, or static fluid bed drying systems for materials are:-

•Guaranteed energy savings, as there is no requirement for any gas, gas/oil or diesel fuels, to generate heat source to dry materials.

•Reduced carbon footprint.

•Operational advantages throughout the transportation, drying, and delivery process.

•Compact size.

•Guaranteed Low maintenance costs.

•Minimal disruption of integrating system in to current process line.

•Liquids, sludges, and aggregates up to 75mm.

•Bespoke systems can dry sand from 60% moisture content down to 0.3%.

•Bespoke systems can handle up to 500 tonnes per hour.

What materials can be dry, pump, or material handle? http://lfpumping.com/material-handling.php

We are confident that this system offers to you the very latest cutting edge technology, packed with financial and delivery savings. We look forward to discussing all your transporting, drying, crushing, and grading applications. ■

Based on 15% mositure content at input stage, the LamiFlo system would be able to reduce the moisture content to below 1%.

Cost Analysis, for Guidance only at this stage, based on up to 100 tonnes per hour.

1. Energy Usage (MJ) / tonne 43.5

- Gasoil (litres) / tonne NA

- Electricity (kW) / tonne 12.09

2. Operating Costs (£) / tonne£0.85

3. Carbon Emissions (kg) / tonne6.49 kg

So for less than £1 per tonne operating costs excluding licence & Maintenance fee we coudl dry your product below 1% moisture content.

if this is of interest pls feel free to fill in the contact form on our website.

I've just read the blurb for the LamiFlo & have the following questions;

Isn't 50m/sec a bit fast for coke?

Where is the energy saving/greenery bit of a roots blower which can handle 500tph?

Roots blower, a big one, and a screw conveyor does not mean less moving parts...?

What kind of screw are you suggesting for 150mm lumps...at 50m/s line speed!?

How is a very large pneumatic conveyor isolated from energy market fluctuations?

How do your particular system dynamics prolong component life?

Passion for this, your product, must be complimented by proper explanation of any novelty or manufacturing quality advantage, or both. Your illustration appears to show a screw conveyor attempting to squeeze material into a contraction while unplugging the affair with copious drive air. There also appears to be a substantial pressurised chamber in place of the usual air delivery pipe.

If you refer to the very recent/current thread on the use of flexible hoses for pneumatic conveying you will see that the gurus do not agree with their use except as a last resort.

Photographs show some separate tanks & stuff but your cover illustration shows the screw almost in line with the blower so the uninitiated amongst us might imagine that the screw was spinning at quite a lick.

Sorry lad: but you need to imrove your claims presentation. So do many other would be suppliers in this game. ■

Isn't 50m/sec a bit fast for coke?

Why is drying coke fast a problem, is it because of abrasion on the drying system. If so our system is based on a very low pressure Laminar Flow System. On the dryer the pipework has a air cushion around the internal edges, which protects the pipework.

Where is the energy saving/greenery bit of a roots blower which can handle 500tph?

This would be a bespoke system, and very much at the large end of the scale. Most of our systems are around 100 tonnes per hour. This would be a 120kW blower, which is substantially cheaper running costs than using gas or gasoil in tradtional drying methods, and less emissions.

Roots blower, a big one, and a screw conveyor does not mean less moving parts...?

Less moving parts than a traditional drying system. The screw is just a feed into the air stream. The Anudros chamber mixes the air and the moist material.

What kind of screw are you suggesting for 150mm lumps...at 50m/s line speed!?

The screw is an auger which just feeds the air stream, is does not need to run at 50m/s line speed.

How is a very large pneumatic conveyor isolated from energy market fluctuations? The fluctuations in the energy maarket place, have recently been surrounding gas, diesel, & oil. We do not need such resoucres for our dryer.

How do your particular system dynamics prolong component life?

The Laminar Flow in a very low pressure system, protects and prolongs the component's life. We offer a full maintennace package, it is our responsibility. We have a sand dryer in the US has been running for 8 years. It is annually maintenance, but no parts have ever been replaced. We have a sand dryer, and a trona dryer, which have been running likewise for 6 years. ■

Can any one suggest.

Please send your email, I will propose you best&reliable dryer.

Note: please inform me do you need equipments before&after dryer.

Hello Mr. Babu,

You might still be interested in coke drying application. We at Helitherm would like to offer you a working solution for drying coke using "HOLO-flo" Screw Dryers.

Please send us your data specification at n.nicdao@yahoo.com so we we can furnish you our product information and proposal.

Thank you.

DBAGlobal has just completed a Feasibility Study for a major steel producer in India.

The study considered the microwave drying of coal prior to feeding the coke batteries.

While this forum is not the place to discuss results, the optimum moisture level seemed to be 7% and the increase in coke production is significant.
