Conventional trough conveyor is the one of the key of material handling system. From

the simplest and shortest conveyor improved to become overland with many vertical and

horizontal curves provide on it. Conventional trough conveyor can convey many variety of

material such as coal, limestone, iron, cement, etc. It helps the transportation direct in internal

of plant or mill, and also can be applied on large area of land. With its economic character,

conventional trough conveyor is the most common used on industries and mine conveying

activities.

Conventional trough conveyor’s belt offers an efficiency of transporting materials in

large quantities of bulk, over distances ranging from a few meters to several kilometers,

continuously. It can be connected with other conveyor by using transfer tower, ploughing

system, or reclaiming system.


Pipe conveyors have come a long way since their

inception and today there are many turnkey contraction

companies offering pipe conveyors in the market. As a

technology, pipe conveyors have improved over the years

and suppliers have incorporated different features to

improve reliability and simplify the operation and

maintenance of these conveyors.

Pipe conveyors offer users the ability to transport

virtually any material in bulk at capacities in excess of 2500

tph. By virtue of its tubular belt form the pipe conveyor is

able to negotiate vertical and horizontal curves and in so

doing, provides an opportunity to eliminate transfer points

in a conveying system.

This attractive feature is complimented by the fact

that the pipe conveyor encloses the transported product,

an environmentally preferred solution compared to

troughed conveyors, can be designed for two‐way

conveying and generally makes of standard mechanical

components.


Stockpile or stockyard have central function in

material handling system which serve material buffers,

reserve storage, and material blending. These stacking

activities are balancing the fluctuation in quantity and

quality of material handled.

Stacker reclaimer consists of bucket wheel

reclaimer and troughed conveyor. It is ideal way to moving

and stacking large amounts of bulk materials in the shortest

possible time. The system of stacker reclaimer need

optimum handling technology which its components must

be matched up each other to ensure smooth transport

flows.


Dome conveyor is the ideal storage unit for any

granular type fertilizer, or also storage multiple types of

material. The conveyor system do reclaiming system

automatically by pulls the stored material to the center of

the dome and discharges to the load‐out conveying system

through an opening. The stored material will discharged

gravitationally until approaches its angle of repose. Then

the reclaim screw is lowered to the pile and the screw

begins to cut into the pile, gently assisting the material to

the discharge opening. Only during the final phase of

reclaim of material from the dome does the 'open' screw,

perform all of the work of drawing material to the opening

discharge.


Structural steel is steel construction material, a profile, formed with a specific shape or cross

section and certain standards of chemical composition and mechanical properties. Structural

steel shape, size, composition, strength, storage, etc., is regulated in most industrialized

countries.

Characteristics ‐ Structural steel differs from concrete in its attributed compressive

strength as well as tensile strength.

Strength ‐ Having high strength, stiffness, toughness, and ductile properties, structural

steel is one of the most commonly used materials in commercial and industrial building

construction.

Constructability ‐ Structural steel can be developed into nearly any shape, which are either

bolted or welded together in construction. Structural steel can be erected as soon as the

materials are delivered on site, whereas concrete must be cured at least 1–2 weeks after

pouring before construction can continue, making steel a schedule‐friendly construction

material.

Fire resistance ‐ Steel is inherently a noncombustible material. However, when heated to

temperatures seen in a fire scenario, the strength and stiffness of the material is

significantly reduced. The International Building Code requires steel be enveloped in

sufficient fire‐resistant materials, increasing overall cost of steel structure buildings.

Structural steel and reinforced concrete are not always chosen solely because they are

the most ideal material for the structure. Companies rely on the ability to turn a profit for any

construction project, as do the designers. The price of raw materials (steel, cement, coarse

aggregate, fine aggregate, lumber (for form‐work), etc., is constantly changing. If a structure

could be constructed using either material, the cheapest of the two will likely control. Another

significant variable is the location of the project.


The general fundamentals of design capacity of conveyor formula:

vFP ww

Pw : Total result of loading condition in a steady operating state of necessary power

at the periphery of the driving pulley

Fw : Total of the motional resistances in top run/return run in steady state operation

v : Belt speed

Motional resistance formula:

SStNHw FFFFF

FH : Total primary resistances – acting on top run/return run along conveying flight

FN : Total secondary resistances – locally limited to the head and tail of the system

Fst : Total gradient resistances – caused by the height differences between bulk

material feed and discharge

Fs : Total special resistances – occurs in partial instances, in top run/return run

(considered separately)
