With increasing space constraints, often, conventional conveying techniques fail to serve their purpose. This has given rise to new technologically advanced conveying equipment, which solve a variety of problems where conventional conveying falls short, thereby enabling new kind of plant design and implementation that was not possible before.

Cleated belt conveyor

Corrugated sidewall/pocket/cleated type belt conveyors are also termed high angle or steep angle conveyors, which are used to transport material from 0o horizontal to 90o vertical lift with zero spillage. The design of the corrugated sidewalls is such that they have excellent resistance to idler penetration on return side supports. The sidewall conveyor carries abrasive or corrosive material with substantially less wear and tear. It can convey many different types of bulk materials.

Advantages

No transfer points: Once the material is loaded onto the horizontal feed point, it stays within the belt until discharged at the head end without transferring from one system to another by reducing dust and pollution.

No spillage: Once the material is loaded onto the belt in between sidewalls, it is prevented by the cross cleats from falling back, besides ensuring that the material remains within the belts effectively along the conveying line.

Maximum utilisation of space: In areas of dockside/existing plants where space is a problem, CBC provides the ideal solution and ability to convey material at angles up to 90? with minimal ground space.

Minimum maintenance: The sidewall belt conveyor, in comparison to mechanical elevators, has considerable advantages and it has been proven. The belt itself requires no maintenance and the reduced number of moving parts plus simple conveyor construction virtually eliminates costly downtime.

Wide range of materials can be handled: With the extensive range of belt sizes available, the system is capable of handling almost all materials, namely: large lumps, free flowing, delicate or fragile substances, highly abrasive material, lightweight or heavy loads. Low power requirement and smooth running are other benefits.

Sandwich belt conveyors

The sandwich belt conveyor has been introduced in India by Bevcon with technical know-how with Dos Santos International, USA. It is marked by originality in design, which has added to the machine's competence. Bevcon's sandwich snake belt conveyors are so named due to the manner in which the material is sandwiched between two rubber belts before it is inclined at angles up to 90o. The material is hugged by the belts throughout the inclined section to ensure that it does not slide back down the incline, even if the conveyor trips. Dramatic reduction in energy use an environmental impact can be achieved with Sandwich belt high angle conveyors that serve as the vital link in any In-pit crushing and conveying (IPCC) system.

Introduction of sandwich conveyors for open pit mine and in pit crushing conveying is breakthrough concept of conveying any mineral from pit bottom to the surface by totally eliminating use of conventional trucks. It also minimises environmental degradation and brings down the operational cost drastically and enhances productivity and product quality its 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.

Advantages

• Unlimited conveying capacity.
• A system suitable for the most rugged mine applications, yet gentle on sensitive and friable materials.
• High availability and low operating and maintenance costs.
• Smooth surfaced belts allow continuous belt cleaning by scrapers and plows. This also facilitates intermediate material discharge by belt plows, as appropriate, before and/or beyond the sandwiched part of the Snake profile.
• All conventional conveyor hardware ensures economy and fast delivery of replacement parts.

Overland/cross-country conveyor

In the power and mining industries, moving large quantities of material long distances reliably is an everyday necessity and requires a special type of conveyor which runs day in and day out. Bevcon in technical collaboration with Dos Santos International, USA, are developing such systems. Using belt conveyors to bring ore and coal from the mines to processing plants or power plants has been proven to be an efficient method of transportation. These conveyors can follow most terrain and have little or no impact on the environment. Operating and maintenance costs are low and they are extremely safe to operate.

Pipe conveyor

The Bevcon pipe conveyor is a modern and environmentally friendly transport system solving numerous problems associated with conventional conveyor systems. Features include:

• Spillage-free transportation.
• No build-up on idlers.
• Can negotiate tight horizontal and vertical curves.
• Can elevate vertically 50 per cent more than conventional conveyors.
• Has excellent belt edge damage control.
• Unaffected by wind and rain thus requires no covers.
• Reduced structural costs by eliminating walkways.
• Cost-effective in comparison to conveyor with one or more transfers.
• Offers the most competitive option to the conventional trough belt conveyor.

Stockyard system

Bevcon Wayors offer innovative conveying systems for stockyard applications for core industries like power, mining, mineral and cement, in technical alliance with FMK-Poland, one of Europe's leading designs engineering company. The stockyard systems are developed in a circular or longitudinal layout incorporating feed conveyors, bucket-wheel reclaimers, stackers, combined stacker/reclaimers, full and semi-portal scrapper reclaimers.

Versatile Stacker: Bevcon stackers can efficiently pile bulk material such as coal, limestone, ores etc, onto a stockpile. Stackers are nominally rated for capacity in tonne per hour (tph). They normally travel on a rail between stockpiles in the stockyard. A stacker can usually move in at least two directions: horizontally along the rail and vertically by luffing (raising and lowering) its boom. Luffing of the boom minimises dust by reducing the distance that material such as coal needs to fall to the top of the stockpile. The boom is luffed upwards as the height of the stockpile increases. Bevcon stackers can rotate the boom. This allows a single stacker to form two stockpiles, one on either side of the conveyor.

Efficient reclaimer: Bevcon reclaimer's function is to recover bulk material such as coal, ores etc, from a stockpile. Reclaimers are volumetric machines and are rated in cubic meters per hour (cu m/h) for capacity, which is often converted to tonne per hour (tph) based on the average bulk density of the material being reclaimed. Reclaimers normally travel on a rail between stockpiles in the stockyard.

Stacker-Reclaimer: The Bevcon stacker-reclaimer as the name suggests, is a single machine with dual function of stacking and reclaiming. Bevcon-FMK stacker-reclaimer machine have significantly less maintenance cost in comparison to individual stacker and reclaimer machines. For instance, the stacker-reclaimer can stack and reclaim bulk materials up to a height of 70 m much higher than any other available conventional conveying system, thereby saving space and capital investment for the industries. It has the following features:

• Rotation up to 220o.
• Stacking and reclaiming radius up to 40 m.
• Stacking and reclaiming up to 10 m height.
• Can be used for different types of materials.
• User-friendly and safe for operators.
• Reliable.
• Capacity up to 1,900 cu m/h.
• Flexible in operation.

Storage sheds

Bevcon, in association with Bafang, China, is going to be making a big difference to Indian stockyard applications in the form of stackers, reclaimers and followed by space frames steel structure circular/linear storage sheds.

Their product range provides the complete solution for mines, cement, power plant dry coal sheds, steel plants, beneficiation plants, ports and terminals. The special feature of the space frame steel structures used for storage sheds is that they are flexible and can be designed in a variety of shapes.

The flat shape of the space frame is flexible and on the basis of web settings, can be divided into cross-truss system, the pyramid system, the cones system and others. When the chord pipes are vertical to the boundary, it is called a straight space frame; when oblique, it is called a diagonal space frame. Space frame roofs have been successfully built in large and medium-size industries across the world.

Advantages

Steel Structure: Lightweight steel structure construction and based on hot-rolled light H steel, lightweight welded steel, high-frequency welded steel, cold-formed steel, sheet steel and thin-walled steel pipes, high-performance structural steel and efficient functional materials assembled to meet the specific space requirements, by the connecting material.

Great performance and flexibility: The weight is only 1/5th of the brick concrete structure, and could hinder even hurricanes at 70 m/s.

Durability: All the parts are made from cold-formed thin-walled steel, and the steel ribs are fabricated by high strength cold formed galvanised panel and it extends the usage to about 100 years. Heat isolation: Fibreglass is good for heat isolation and preservation. 100 mm thick R15 equals to 1 m brick on thermal resistance effective.

Soundproof: Hollow glass, which could insulate more than 40 db sound. The wall made from lightweight steel ribs and gyps could insulate more than 60 db sound.

Coziness:

Lightweight steel wall gets respiratory function, which could adjust indoor humidity. The roof has good ventilation ensuring the air and heat output.

Dense phase pneumatic conveying systems

The Bevcon pneumatic conveying system is the most efficient and effective method of transporting granular and bulk solid materials to storage or to process unit within a production environment. Bevcon, in technical collaboration with Nanjing Air Conveying, China, are specialists in designing, manufacturing and implementing high capacity, long distance and high temperature, lean and dense phase pneumatic conveying systems. Lean phase PCS is suitable to move materials at high velocities (15-30 m/s).

Dense phase PCS technology is suitable for transporting difficult, abrasive and/or friable materials along a pipe in plug form at very low velocities (2-8 m/s). This results in minimal wear on pipes and bends, promoting minimum maintenance and long life. Efficient use of compressed air also gives low power consumption and running costs.

Highlights:

• Uses gas (or air) as the conveying medium.
• Transfers bulk materials of almost any type.
• Moves larger quantities of material.
• Moves material at longer distances.
• Flexible in terms of rerouting and expansion.
• Transports from one or more sources to one or more destinations.
• Pipe lines can be constructed at any desired angle.
• Utilises less space.
• No spillage during conveying.
