Koenig Arc Valve

Koenig Arc Valve is Air Tight Shut-Off valve with spherical disc, operated through Pneumatic Actuator and used in the Material lines namely Material Inlet, Material Discharge and Vent line in Pressure Tank systems.

Operating Principle

Koenig Arc Valve has a sturdy Spherical Disc which can cut through a full material flow without any limitations. The spherical Disc is coated with high-grade wear protection on which the inflatable Sealing gasket is mounted thus ensures more reliable, long service.

Koenig Arc Valve is designed for an operating pressure of 10 bar. Sealing air pressure is supplied 1 bar above the max. conveying air pressure to ensure 100% air-tight sealing.

Koenig has 5 different sizes of Arc valves 150mm, 200mm, 250mm, 300mm and 400mm which meets all the application of Koenig Pressure Tank conveying systems.

Koenig Flow Control Valves

Koenig Flow control valves are used to Regulate the material withdrawal from silos, bins etc. when mounted along with PneuSlide (Pneumatic Air Activated Gravity Conveyor).

Koenig Flow control valves developed from our past experiences and various application handled by us to withstand all vigorous abrasive materials like Fly ash, Alumina.

Koenig Flow control valves have basic type with different actuators have in common, the extremely high accuracy of a controlled flow of pulverized bulk goods with reproducible results. We have three actuations namely Manual, Pneumatic (On-off), Motorized (Regulating / Dozing).

Koenig Flow control valves, a complete disassembly becomes unnecessary. Maintenance can be carried out while the valve remains built-in. After having taken off one of the side plates the roller can be taken out. The gasket is then accessible and can be replaced if required. Re-assembly is done in reverse order.

Koenig Flow control valves are having wide range of sizes 200mm, 300mm, 400mm, 500mm and, 630mm and 800mm, cater to convey a max. capacity of 1037m3/hr.

Koenig Rotary Valves

Koenig Rotary Valves are designed to suit the application and we have 3 variants namely Light Duty, Medium Duty and Heavy Duty. Koenig Rotary Valves are manufactured with a square and circular flange to reduce installation / building height. We have wide range of Rotary valves and supply up to 300 m3/hr.

Light Duty Rotary Valves

Koenig-LD Rotary Valve is specially designed for use in combination with dust filters, cyclones and product separators. These valves are suitable for use in simple and light industrial applications whereby the valve primarily functions as an airlock.

Medium Duty Rotary Valves

Koenig-MD Rotary Valves have been specially designed to offer a suitable and economic solution for standard applications with a limited pressure differential up to 0.5 bar.
These valves are used extracting/dosing material, mounted below silos/hoppers for abrasive or mildly cohesive products.

Heavy Duty Rotary Valves

Koenig-HD rotary valves are employed in the conveying and dosing of almost any kind of product in the most demanding applications. These valves are eminently suitable for handling powdered and granulated materials in pneumatic conveying systems up to a pressure differential of 1.5 bar.

Koenig Lump Breaker

Cement when it is stored in silos sometimes tends to agglomerate especially in silos irrespective of the withdrawal system or located in high humid climates.

Occasionally parts of the agglomerated cement move with fresh cement – which flows smoothly – towards the discharge spout. At this bottleneck, these lumps plug up the discharge aperture causing discharge trouble. The cement flow is reduced or comes to a full stop.

The Koenig Lump Breaker placed at the silo discharge disintegrates the lumps to a size which allows the cement to pass the aperture of the flow control gate trouble-free.

The combination of Koenig lump Breaker and Koenig Flow Control Valve in a cement withdrawal system from a silo leads to a 100% blockage free operation thus gives reliable, low cost plant operation.

Koenig Lump Breaker are having wide range of sizes 200mm, 300mm, 400mm, 500mm and, 630mm, cater to convey a max. capacity of 1037m3/hr.

Koenig Pump

Koenig Pump is a screw type pump used as a feeding device to Medium Phase Pneumatic Conveying of pulverized materials such as Cement, Raw meal, Coal, pet-coke, lignite, Soda Ash and many other powdery materials which are less abrasive and good fluidization properties. This is a continuous Conveying and hence most of the coal or pet-coke firing application, screw pumps are predominantly used.

To get maximum operating life and low maintenance cost, each screw surfaces are treated with special coating to suit material being conveyed.

Operating Principle

Material received in the Inlet hopper pushed through specially made variable pitch screw which compacts the material when advances towards the discharge position. This compacted material acts as the material sealing to feed into the Conveying line. To protect the bearings from material accumulation, Air purge sealings are used at both Drive and Non-Drive bearings.

Koenig has 4 different sizes of Pumps, K150, K200, K250 and K300 catering up to 250 m3/hr. conveying capacity and max. conveying distance of 300m.

Koenig Airlift

The Koenig Airlift for silo charging, kiln feed application facilitates a dust-free vertical transport. It does not require any maintenance as there are no mechanical moving parts in the conveying stream which need to be maintained.

A rotary blower supplying the conveying air does not require much maintenance either. Parts of an airlift system are: The cylindrical air-lift body made from steel with fluidizing bottom, the vertical nozzle and conveying pipe, a cyclone separator (when not charging directly a hopper or a small silo). A rotary blower or a group of blowers supply the necessary oil-free conveying air. There will a dedicated Rotary blower for fluidization.

A head of conveying material forms the air lock against atmospheric pressure; in other words, the higher to material lift, the higher the airlift body height.

Koenig offers Airlift up to a capacity of 300 MTPH and a max. vertical conveying distance of 80m.

Centrifugal Bucket Elevators

Centrifugal bucket elevators are chosen when there is a need to move large amounts of material quickly. Instead of direct loading, buckets serve as the loading apparatus, scooping material up from the boot or inlet section. For this reason, durable buckets should be selected with this design. Centrifugal force at the head pulley “throws” material from the buckets into the discharge chute. 

Centrifugal style elevators are ideal for materials like Raw Meal, Cement, sand, gravel, woodchips, and other free flowing bulk materials where fragility is not a concern. 

Continuous Bucket Elevators

Continuous bucket elevators are designed to handle friable, fragile materials to minimize product degradation or damage. 

Material is fed into the buckets from an inlet chute. Buckets are closely spaced on the belt or chain to allow the material to flow over the backside of the preceding bucket, whose extended sides form a chute to guide the material into the discharge spout.

 

Applications

Bucket elevators can handle a variety of materials, and therefore are used in many different industries and applications, though generally, they are not suited for wet, sticky materials, or materials that are stringy or tend to mat or agglomerate.
