GEVELSBERG, JULY 2001

Gentlemen,

Thank you very much for your interest in our company.

The enclosed „TRADING REFERENCE“ supplies you with a complete overview about our companies and our services.

Since your special interest is focused on the

"DUST SUPPRESSION SYSTEM - ECS" by LINGENBERG


we are pleased to provide detailed information as follows:


"ECS" means "Emission Control System"


"ECS" has been developed to perform to the very stringent cleanliness requirements of the German regulations governing air pollution by dust and other solid pollutants. "ECS" meets the strict clean air requirements of "TA - LUFT" the German Clean Air Act. "ECS 89" is the only system named specifically in the German standard VDI 2584.

"TA LUFT" regulations cover the following activities:

- preparation, production and handling of materials that generate dust

- loading, transportation and unloading of materials

- storing and reclaiming of bulk material

- tipping materials

Examples of these activities are:

- quarries and mining - open pit as well as underground

- shiploaders and shipunloaders

- bucket wheel excavators, stackers, reclaimers and combined machines

- preparation plants,- coal, iron, quarries, cement factories etc

- conveyor belts, especially at transfer points and loading bins

- recycling plants

- stockyards

- bulk materials handling

- iron- and steel plants


The first requirements of the clean air acts around the world are eradication, avoidance and minimization of pollutant emissions.


"ECS" has been developed to meet these requirements.

CLIENT: BORAL GRANITE - KAMENZ / GERMANY
MATERIAL: GRANITE
GRAINING: 0/5 mm
HANDLING RATE: 120 t/h
"ECS" is:

- available at significantly lower prices for new installations than existing antiquated systems
- very easy and economical to retro-fit in existing plants
- unrivalled in its low operating-, maintenance- and spare part costs
- of innovative rigid technical, mechanical and structural design, that gives
many years of optimal service under severe industrial operating conditions
- a successful system - proven by reliable installations operating very satisfactorily
around the clock, around the world.
CLIENT: RAS AL KHAIMAH ROCK CO. - RAS AL KHAIMAH / UAE
SCREENING OF LIMESTONE
GRAINING: 0/8 mm
HANDLING RATE: 60 t/h
"ECS" dust suppression systems are providing reliable and highly satisfactory service, - for example - in:


- Africa - Arabia - France - Germany - India - Italy - Portugal - Spain - Taiwan - South America


"ECS" - TECHNOLOGY:

"ECS" encloses emitting particles of fine dust in a small shell of a specially prepared mixture of water and surfactant - before emissions arise.

The "ECS" process encapsulates dust driftings in a tight veil of mist which the dust particles are not capable of penetrating. The dust particles and the fog droplets combine which each other. This "ECS" process increases the mass of each particle and eliminates its ability to float in the air. Therefore, the heavier mass particle settles down into the material being conveyed.

The following photos show clearly these facts. They were taken from a demonstration plant operated at the trade fair STEINEXPO.

Photos show processing of 300 tons Basalt - graining 0/5 mm - per hour.

The quantity of mixture sprayed is 570 liters per hour. This means that, related to the above handling rate of 300 t/h, the materials inherent humidity increases by 0,19 %.

Another interesting figure: Above 570 liters of mixture contain surfactant in the ratio of only 1 : 4000 – any liter of water therefore contains 0,25 MILLILITER of compound. In other words: 300 tons of BASALT contain 142,5 MILLILITER surfactant. It follows that the mixing ratio handling rate / surfactant is approx. 1 : 2.105.200.

IMPORTANT REMARK

"ECS" functions in a pressure range up to 12 bars (1,2 MPa)

Processes which use high pressure or compressed air pose a considerable health risk as they produce aerosols which are inhalable into the finest alveolae where

they can cause serious disease. This is not the case with the ECS process that uses

low pressure.

The Standard EN 481 of the EUROPEAN UNION ( identical with ISO-CD 7708 and US-ACGIH) provides detailed information on this topic.

An outstanding characteristic of "ECS" is the extremely low consumption of mixture. Depending on the kind of material, the consumption is from 0,05% to 0,3% of the materials handling rate per hour.


Advise us of your special problem.

Our catalogue covers more than 40 different types of material and in each case specifies the required volume of mixture for an entirely satisfactory dust suppression effect.
