Bespoke Quarry & Recycling Solutions 

 

FINEDOOR is a privately owned company established in 1984 and has progressed from a `Proprietor Run Company` with an annual turnover of £300,000 to a company employing specialised personnel with a turnover of circa £2m based on a 50% split between UK and Export sales.

The management have over 40 years of previous experience in providing bespoke solutions for the quarry and recycling industries in the fields of design, manufacture, installation, operation and repair of quarry equipment and plant. The solutions combine Finedoor equipment such as hoppers, feeders grizzlies, conveyors, screens and the Ortner plus the most appropriate third party equipment to solve clients problems.

Over the years our customer base has grown, and now includes most of the major quarrying groups in the UK: CEMEX, Tarmac, Lafarge, Hanson Aggregates; with sales on a repeat order basis.

International sales have also increased and these vary from individual units to the design, detail and supply of all necessary components for new, or upgraded plants to large international companies in the Middle East, which include CEMEX, Tarmac, locally owned government companies and large privately owned companies, including several units which are operating in Europe. We have also worked with clients in other territories around the world ranging from locations in Africa to India.

Finedoor offers a unique service of designing and manufacturing screens to fit into existing locations, with no need to modify existing chutes or steelwork.
We also specialize in replacement or new supply of asphalt screens.

ORTNER

The ORTNER is a revolutionary concept for dewatering, removing fines, classifying and rinsing sand and other materials up to 60mm and has the performance capabilities and advantages unmatched by other machinery. It is currently used by the majority of the major aggregate producers in the USA.

The ORTNER can wash fine and course material up to 75mm providing the flexibility to produce many varied products
with one machine. Dry material may be fed to the ORTNER
to remove excess fines or rinse coarse material by adding a small quantity of water.

When fed a wet slurry, as from a density separator or a hydrocyclone, the ORTNER may be used to dewater the product. It may also be used to remove excess fines from
the slurry or it may classify the slurry.

Operation
 
The operation and principle are simple. Material is fed to a slowly revolving pan on an incline and vibrated at high speed. The high speed vibration quickly separates the various sizes of material with the fines and water rising to the top and flowing over the weir to the discharge.

With the coarser particles sink to the bottom the rotating pan carries the settled particles up the machine and out of the water, where a stationary plough diverts the dewatered material to a centre discharge chute. The driving and vibrating
mechanism is mounted under the pan, preventing any
contamination with the water and processed material, thus
increasing the life of the components.

It is possible to vary the angle, speed, and vibrations of the
pan.
This gives the ORTNER a wide range of flexibility and increases
its capacity and efficiency.

Design Features

DRIER PRODUCT. High efficiency produces dry product for ease
of conveying and stockpiling.

LESS POWER. Horsepower requirements range from 2-15 HP
depending on model. Normally one-fifth the power consumption
of conventional machines.

HIGH CAPACITY. Unmatched performance capabilities and flexibility.

LESS WATER. A relatively small amount of water is needed to
rinse and remove excess fines.

LESS WEAR. Lowest wear and maintenance cost results from
simple design.

LESS WEIGHT. Compact and lightweight for portability and
easy installation.
 
Ortner Selection and Tests

The proper ORTNER application and sizing must take into
consideration the type of material, feed gradations, product
specifications, water in feed and availability, tonnage required
and feed particle shape.
