Mechanical material handling equipment

Drag chain conveyors

Drag chain conveyors are ideal for transporting powdered and dusty materials. Such materials that are often handled in power plants, smelters, pulp & paper and chemical industries, among others.

By choosing the correct link and pin material, even the most abrasive and hot (up to 600ºC; 1.112ºF) materials can be handled safely and effectively. Kopar drag chains are usually made of case hardened or tempering steel.

Kopar drag chain conveyor design offers variability to layout and as high inclination angles and different configurations are possible. With Kopar drag chain conveyor you can achieve capacities up to several hundred tons / h with low operational cost. Extra effort is always given to ease of maintenance.

Screw conveyors

Screw conveying is a reliable method for the transport of a broad range of bulk materials for a variety of applications in several industries.

A screw conveyor uses a rotating helical screw blade, normally within a round tube or U-shape frame, to move granular materials. Screw conveyors offers high flexibility in layout-wise as the conveyors can be installed in different inclination angles.

Kopar has a lot of experience using screw conveyors also in very challenging applications i.e. in precise feeding, silo reclaiming or in moist material conveying; all these conditions can be successfully met with good engineering.

Frames and screws can be manufactured of carbon steel, acid resistant steel, wear resistant steel or stainless steel, depending of the needs.

Capacity: 0-300 t/h (typical)

Length: up to 10 m (typical)

Inclination angle: up to 45 degrees (typical)


Rotor and roll crushers

There are two main types of crushers in the Kopar product range. The rotor crushers are usually used in first stage acting as a pre-crusher followed by the roll crusher used for the primary crushing stage producing the needed end-product.

Kopar crushers are suitable in crushing materials that are cloddy or lumpy but still relatively easily degradable to make them suitable for further processing. Typical materials to be crushed are for example waste heat boiler slag, dust lumps and bottom ash.

Maximum capacity varies depending on the material characteristics. For detailed information for your needs, please contact us!

Bucket elevators

One of the most efficient ways to elevate bulk materials vertically is with a Kopar bucket elevator. Capacities up to several hundred tons per hour can be achieved reliably with low operational cost.

Bucket elevator consists of a series of buckets attached to a belt or chain rotating trough sprockets or pulleys located at the top and bottom of the unit. The buckets are in a tight housing to contain the material and dust inside.

Our bucket elevators are widely applicable in conveying concentrates, ashes and other highly abrasive and dusty materials.

Capacity: 0-300 t/h (typical)
Height: up to 60 m (typical)
Operational temperature: up to 600 degrees, chain up to 200 degrees, belt


Bucket excavators

In metallurgical industry hot matte, slag and other melted materials can be granulated in a process, where the flow of molten material is sprayed by water causing it to disintegrate. The formed granules drop into a pit filled with cooling water.

A bucket excavator lifts the granules up from the pit and performs both the lifting / conveying and dewatering simultaneously for the successive process stage. From the excavator, the granules can be moved either onto a dewatering screen that further reduces the remaining water content of the granules, or they can be directly fed into a silo by a box-type belt conveyor. Water screens, belt conveyors and silos are also part of Kopar product portfolio.

Capacity: 0-300 t/h (typical)
Length: up to 25 m (typical)
Inclination angle: up to 70 degrees


Rotary valves and feeders

Rotary valves and feeders are critical equipment in many processes through various heavy industries. Function of the rotary feeder can be dosing, material flow controlling, or they can act as an airlock to prevent process disturbances caused by unwanted air flows.

Kopar rotary feeders are well known in heavy industries with hundreds of functional installations. Kopar equipment has especially been granted about being very tight both outwards from the process but also inwards. Steady dosing capacities can be achieved ranging from tens of litres to hundreds of tons per hour, depending on your needs and the application.

Capacity: 0-300 t/h (typical)

Operational temperature: up to 300 degrees (typical)

Standard sizes:
Rotary valves
RV 200-200
RV 250-300
RV 300-300
RV 300-350
RV 380-350
RV 400-450
Rotary feeders


Drum screens

Kopar has a reliable and compact solution for screen sand from the bottom ash stream which is then to be circulated back to the power boiler. As the fuels burned in boilers contains more and more impurities challenges are generated for the bottom ash screening. Therefore, Kopar has put focus in developing robust easy operational equipment which is simple to maintain.

Combination of both mechanical and pneumatic cleaning together with unique screen drum changing method, Kopar drum screen is well suited for challenging conditions.
