While safety and effective cost are prime considerations, delivering design capacity and easy maintanance are equally crucial

As the name replicates BMH (bulk material handling) involves transporting large quantities of dry materials from location to location efficiently and safely with the final destination often as the last step in an industrial processing application. In this context, BMH equipment involves various types belt conveyors which plays a major role. Further, the belt conveyor technology is the basic content used or mixed with various other equipment and applications to form a complete engineering solution.

Measures to buy cost effective but efficient BMH solution

Major parameters for equipment selection
Turn-key processing solutions utilises its knowledge and years of experience to design systems for handling dry materials such as coal, iron ore, cement, gypsum, wood chips etc. Bevcon’s BMH systems are part of core industrial sector viz. mining, ports and bulk terminals, steel, power, cement etc. V. Manoj Kumar, Assistant Vice President – PMG, Bevcon Wayors Pvt Ltd informs, “While selecting any BMH systems, plant layout with proper and seamless material flow arrangement plays a very vital role. For preparation of layout the following aspects are critical viz. site contour, routing, material specification, capacity requirement etc.”

Once the layout is done, the effective and optimum way of equipment selection is indeed the final step in giving proper solution. Equipment selection is on the four major parameters as mentioned below.
• Productivity
Equipment is ensured to deliver the designed capacity.
• Reliability
Equipment is available with no failure.
• Easy maintenance
Equipment is operation and maintenance friendly with low cost of maintenance.
• Safety
Equipment is provided with highest operating safety standards.

Importance of system performance
The main purpose of a BMH system is to continuously transport and supply bulk materials to units in processing plants. Swarbhanu Banerjee, Sales Manager – Surface OE, Komatsu Mining Corp. Group explains, “When selecting BMH solution, we need to consider best possible technologies for any application. With the advancement of technology, we can handle material at a 90-degree angle by using high angle conveyor, which is cost effective and eco-friendly.”

He adds, “Proper engineering and selection of well proven components for drives, winch take up systems and belt turn over stations, along with an effective control system play an important role in the performance of the system.”

Komatsu’s contributions
Banerjee from Komatsu explains the company’s contribution towards BMH as follows below:

• Long-distance conveyor
The long-distance conveyor eliminates transfer points, thereby improving productivity. It can accommodate horizontal and vertical curves, as well as cross roads, rivers and railway lines. Additionally, The company’s support, structures can be mounted on sleepers or on concrete foundation.

• Conveyor based- BMH
Komatsu Mining offers conveyor-based material handling equipment necessary for removing muck and spoil from tunnel excavation sites. This equipment is specifically engineered to smoothly handle the transportation of materials from the tunnel excavation site to the surface.

• High angle conveyors
The HAC has proven itself to be a versatile and money saving method for elevating or lowering bulk materials continuously from one level to another at extremely steep angles (up to 90 degree). This system holds the conveyed material continually— eliminating relative movement between material and belts. It does not confront materials, rather it conforms to surface shapes without incurring high local forces. Soft, gentle pressure assures the preservation of product quality and long life for the equipment.

• Reclaim feeders
Reclaim feeders are an efficient and cost-effective mechanism for blending materials, reclaiming stockpiles and feeding material. They currently operate in various applications including, but not limited to, synthetic fuel plants, power plant facilities, synthetic gypsum plants, truck load-out facilities, port load-out facilities, and coal mining operations. The company offers reclaim feeders with electro-mechanical or hydraulic conveyor drives. Rotary pick breakers for stockpile applications requiring size reduction are also available. Mobility options include skids, wheel or crawler mounting.

Bevcon’s innovative conveying systems and equipment
Bevcon provides concept to commissioning solutions and execute turnkey or EPC projects for all material handling applications for all sectors and establish them as a reliable brand in BMH industry. Kumar from Bevcon Wayors informs, “We always strive to bring best technologies to India with most cost optimised manner and in the end our customers will have winning edge in their processes and business. Bevcon executes project with blend of latest technology with conventional systems in most optimised manner which will enhance the operations reliability. Bevcon’s core strength lies in use of innovative conveying systems and equipment which caters present day demands of Indian mining sector.”

Bevcon offers the innovative equipment as mentioned below:

• Sandwich belt high angle conveyor
For vertical conveying application which is revolutionary concept; Bevcon’s technology tie-up with M/s. Dos Santos intl. USA, who are world’s foremost authority on high angle conveyor applications and design of sandwich belt type high angle conveyors for open-pit mine (In-pit crushing conveying), which is breakthrough concept of conveying any mineral from pit bottom to the surface by totally eliminating use of conventional trucks. It also minimises the environmental degradation; flexibility of conveying profiles makes it one of the unique materials handling equipment of current generation and brings down the operational cost drastically and enhances productivity by retaining product quality. It’s unique concept ever tried in Indian mining industry. These high angle conveyors are not new at all, but have not found wide use in IPCC systems where they can realise the greatest advantage.

• Overland pipe conveyor
Overland pipe conveyor is a modern and eco-friendly transporting system for all kind of bulk materials by overcoming numerous challenges associated with conventional conveyor systems. Pipe conveyors have best capabilities of transferring materials between two points, managing both horizontal and vertical curves as well as high inclinations which are difficult in case of trough conveyors. It eliminates multiple transfer points and exposure of material to atmosphere. Pipe conveyor not only protects the conveyed material against external influences such as climatic conditions, it also avoids material loss and spillage and thus, protects the environment.

• Overland troughed conveyor
Overland troughed belt conveyors are designed to carry high tonnage loads over long distances. Bevcon’s long distance conveyor design ensures lowest power consumption per ton of conveying. Overland belt conveyors have been proven to be an efficient method of transporting bulk material over long distances and costs are often lower than with truck transportation.

We always strive to bring best technologies to India with most cost optimised manner.
