is drawn from the tipping truck in a controlled stream, dust generation
is significantly reduced, minimising environmental pollution.
A wide belt design, with vertical hopper sides, enables fast
truck discharge and the efficient conveying of any material,
without the risk of blockage. Steel apron bar technology provides the
strength of an apron feeder, with clean operation. Conveyor chains are
always outside the material flow, which means chain wear is reduced
and inspection is easy. The MF0814T is self-propelled and is powered
by an integrated Tier 3 diesel engine. Self-steering through a remote
control unit can be deployed quickly and independently for flexibility,
total control and optimum efficiency.
A key safety feature is an emergency stop facility. Optional emer-
gency pull cords can also be installed on each side of the machine.
BLT SA, exclusive distributors of the supports the SAMSON range
in sub-Saharan Africa, offers a technical advisory, parts and mainte-
nance service.
“This new tracked machine, which is modelled on the original
Samson
®
material feeder, has been developed to meet the
demands of themining and quarrying sector,” says Keith Dowie,
project development engineer for BLT SA’s SAMSON bulk materials
handling equipment.
“These automated handling systems are designed to join together
fixed and mobile equipment, offering flexibility and an economical
alternative to expensive fixed bulk handling installations.
“This new robust MF0814T tracked material feeder, with a holding
capacity of up to 100 tons, is designed for high accuracy in discharge
control and can operate efficiently in arduous environments.
This system can efficiently handle materials with a bulk density up to
3,2 t/m³ and lumps up to 400 mm. Typical materials include limestone,
coal and coke, raw slag, alternative fuels, clays and shale, as well as
heavy mineral ores.”
This system, which is a flexible and cost efficient alternative to
conventional underground hoppers, is installed above ground by
simply being bolted to a flat concrete slab foundation, eliminating
costly civil engineering works. Even in fixed installations this portable
system can be easily relocated for future plant development.
Samson material feeders are suitable for heavy duty applications
with continuous use, including impact loading from articulated dump
trucks and large loading shovels, providing a buffer storage capacity,
without the need for large ramps or underground pits. Since material
Recently, in a test* performed by the independent technical
inspection organisation TÜVNord, the LP6500was compared
with two similar duplex roller models from other manufac-
turers. The test provided confirmation that the LP6500 has lower
vibrations in the handle and lower machine noise than the other
machines tested.
Test results conclusive
In the vibration test the LP6500 showed a hand-arm vibration level
of only 4,14 m/s
2
in the top handle, while one competing roller was
measured at 7,01 m/s
2
in the direction handle. Thus
the hand-arm vibration level in the handle of the
LP6500 is 2,87 m/s
2
lower, which means consider-
ably less strain on the operator during a working
day. In the noise emission test, the LP6500 showed
a sound pressure level of only 89 dB(A), which is
3 dB(A) lower than one of the competing machines,
and 6 dB(A) lower than the other.
Effective on virtually any surface
The LP6500 provides high compaction efficiency
on thin granular soil layers, such as sand and gravel.
When compacting silt, the compaction effect
depends largely on water content and the LP6500
is most effective on thin layers. On asphalt the end
results are excellent and the LP6500 is well suited
for smaller jobs in areas such as pavement
construction or repair, narrow roads, play-
grounds or parking lots.
*Atlas Copco Construction Tools AB in
Kalmar, Sweden, initiated and performed
the comparative test under the supervi-
sion of TÜV Nord. All steps of the process,
from preparation to tests and measure-
ments were conducted in accordance
