Bridge Type vs. Portal Scraper Reclaimer: Key Differences

Structure and Design

There are big differences in how these machines look and work. Bridge type reclaimers have a bridge that goes sideways. Chain scrapers are attached to the bridge. The bridge moves on rails. Portal scraper reclaimers have one long arm called a boom. The boom moves slowly and covers large piles. You can see their main features in the table below:

Feature	Bridge Type Scraper Reclaimer	Portal Scraper Reclaimer
Operational Mechanism	Chain scrapers on a horizontal bridge	Single boom with scraper
Structural Configuration	Bridge on rail tracks	Single long boom
Motion	Linear travel along bridge	Slower movement of scraper
Speed	Steady and slow	Slower than bucket wheels
Reclaiming Capacity	Lower capacity	Higher capacity
Wear on Components	Greater wear on bucket wheel parts	Less wear on scraper parts

Bridge type reclaimers are good for mixing and steady work. Portal scraper reclaimers handle bigger piles and need less fixing.

Operation and Capacity

You should think about how much you want to move. Bridge type reclaimers are best for mixing materials. They take material from the end of the pile. Portal scraper reclaimers can take material from any part of the pile. This means they are more flexible and can work faster.

Here is a table that shows how much each type can move:

Reclaimer Type	Capacity (tons per hour)
Portal Scraper Reclaimer	Up to 4,000
Bridge Type Reclaimer	50 - 3,000
Circular Scraper Reclaimer	Up to 6,000

Portal scraper reclaimers can move up to 4,000 tons every hour.
Bridge type reclaimers usually move between 50 and 3,000 tons each hour.

Pick a portal scraper if you need to move lots of material fast. Bridge type reclaimers are better for steady work and mixing.

Typical Applications

You find both types in many places. Bridge type reclaimers help mix and blend materials. You see them in cement plants, steel mills, and power plants. They keep the supply steady and mix things well.

Portal scraper reclaimers work where you need to move a lot and have big piles. You see them in mining, power plants, cement factories, fertilizer, wood processing, and sinter plants. They handle things like coal, limestone, ores, and fertilizers.

They can be more reliable if you keep up with checks. Dust, bad weather, and heavy loads can hurt both types. Teach your team to find problems early. Fast repairs and regular checks help stop big breakdowns.

Tip: If you take care of your reclaimer, it will last longer and cost less to fix.

Layout and Space Considerations

Stockyard Compatibility

You should look at your stockyard’s shape before you pick a reclaimer. Bridge type reclaimers work best in long and straight stockyards. You see them in places with simple layouts and rails that do not curve. These machines need enough room for the bridge to move across the pile. If your stockyard is simple, you can put in a bridge type reclaimer without trouble.

Portal scraper reclaimers give you more choices. You can use them in stockyards with strange shapes or small spaces. These machines can fit different layouts by using special ways to stack and take out material. For example, you can use on-ground travelling stackers if you cannot build a strong roof. Circular buffer storage also helps you save space. You keep bulk material against a wall and control it from a center column. This setup makes fixing things easier and helps you use your space better.

Tip: If your stockyard is not a normal shape or space is small, portal scraper reclaimers are more flexible.

Installation Flexibility

You want a reclaimer that fits your site without big changes. Bridge type reclaimers need strong bases and straight tracks. You must plan your stockyard well before you put one in. These machines work best in new places or where there is lots of room.

Portal scraper reclaimers let you set up equipment in more ways. You can put them in open spots, under light roofs, or inside round storage buildings. You do not need to change your stockyard much. This flexibility helps you save time and money when you install them.

Reclaimer Type	Best for Stockyard Shape	Installation Needs
Bridge Type	Straight, regular	Strong foundation, rails
Portal Scraper	Irregular, circular	Flexible, less groundwork

You should pick a reclaimer that matches your stockyard and how you want to install it. This helps you get the best use out of your equipment.

Decision Factors

When you pick a reclaimer, you need to think about a few things. This part helps you choose by showing what matters most.

Material Type

You should know what material you want to move. Some reclaimers work better with certain materials. If you handle powders or want less dust, enclosed conveyors help you. Drag conveyors are good for heavy and rough materials. Cantilever chain reclaimers use long booms and a truss to collect material well.

Here is a table that shows which reclaimer works for each material:

Reclaimer Type	Application Description
Enclosed Conveyors	Good for powders and dust control
Drag Conveyors	Best for heavy, abrasive materials
Cantilever Chain Reclaimers	Collects material with long booms and truss system

If you work with lumpy or grainy materials, bucket wheel reclaimers move a lot and work steadily. Stacker reclaimers are good for powdery materials and help you stack and take them out easily.

Reclaimer Type	Suitable Material	Operational Requirement
Bucket Wheel Reclaimer	Lumpy and granular	High capacity and continuous operation
Stacker Reclaimer	Powdery	Efficient stacking and retrieval

Tip: Always match your reclaimer to the material you use. This keeps your work safe and smooth.

Capacity Requirements

You need to know how much material you want to move each hour. Bridge type scraper reclaimers can move up to 1,600 tons every hour. Portal scraper reclaimers have many choices, from 50 tons up to 8,000 tons per hour. If you need to move lots of material fast, portal scraper reclaimers give you more options.

Bridge type scraper reclaimer: Can move up to 1,600 tons per hour.
Portal scraper reclaimer: Can move 50, 100, 150, 200, 250, 300, 400, 500, 750, 1,000, 1,200, 1,500, 1,800, 2,000, and up to 8,000 tons per hour.
