Products

Ceramic Rotary Valves
KREISEL wear-resistant ceramic rotary valves are characterised by high performance, high throughput and increases in service life by a factor of 10 to 20 compared with steel valves depending on the material to be conveyed. KREISEL ceramic rotary feeders have a high availability, cause lower maintenance costs and lead to significant cost savings.

Rotary Valves
KREISEL rotary valves are produced in a wide range of versions for theoretical volume flows of up to 2,700 cubic metres per hour. They have proven themselves for many years in process engineering systems for environmental and bulk material technology in many sectors. Rotary feeders are used to deliver bulk materials with constant volume flow rates from containers to connected system components or conveyor systems, and for metering. For example, they are used under filters and cyclones, to extract bulk materials from air conveying circuits with minimal pressure loss. Via mixers, dryers and mills, they are used for volumetric metered feed of the bulk material in continuous mixing and processing processes with an air seal, and also as a thermal shield. Special designs Blow-through rotary valves Cutter feeders Self-cleaning rotary valves Tangential rotary valves

Two-way distributors
KREISEL two-way distributors are used to direct the flow of bulk material optimally.

Slide gates
KREISEL slide gates are used as locking, metering and safety components in process engineering systems in all industry sectors.

Double Flap Gates
KREISEL double flap gates are used for continuous delivery of flowing, dust-based, granular and coarse bulk materials – while simultaneously sealing process and vacuum chambers.

Pressure Vessels
KREISEL pressure vessels allow maximum charging of the transport gas with the conveyed product at lowest transport speeds. KREISEL pressurised gas transport means -Gentle transport of the conveyed product -Low pipe wear -High availability of the conveyor system -Minimal energy requirements -Low maintenance Manufacturing range -SingleFeed (Single pressure vessel systems) -TwinFeed (Twin pressure vessel systems) -DoubleFeed (Two-storey pressure vessel systems) Expertise KREISEL is a TÜV-approved manufacturer of technical welded products for container construction in accordance with AD 2000 Leaflet HP0.

Recuperators/heat exchangers
KREISEL recuperators pick up waste heat from production, return it to the process in a circuit or for other energy uses. The specially-developed type K radiation recuperators generate optimal high combustion air temperatures and reduce fuel consumption significantly. Designed and built for the respective application, they are primarily used in the Glass industry for recuperative heated glass melting furnaces, Ceramics industry, Metallurgy and in other Energy-intensive industrial sectors.

Filter Systems
KREISEL filter systems separate the bulk material dispersed by the conveyed medium in the conveying process. They ensure that the emissions remain far below the limits. Depending on the application and space available JET bag filters can be used as collecting or bunker-mounted filters. As a result of the modular design of the filters up to 200,000 cubic metres of air can be cleaned for dust removal each hour.

KREISEL Cyclone-Filter
Cyclone filter are a space saving combination of cyclone separator and JET filter especially for dust separation into pneumatic conveying systems. KREISEL cyclone filter are available for volume flow up to 9,000 m³/h as standard round filter and also as shock pressure resistant design.

KREISEL Pneumatic conveyance
Pneumatic conveying systems from KREISEL are used for conveying bulk materials of all kinds. It must be assumed here that the corresponding bulk material can be conveyed pneumatically. We can check this in our KREISEL technical centre if necessary. Pneumatic conveying systems are used for conveying distances of more than 1,000m and conveying capacities of more than 200 t/h. KREISEL has different technical solutions at its disposal, which are used depending on the requirements. Different factors, such as conveying capacities, bulk material properties and conveying distances play a central role in the correct selection of the appropriate infeed device. In this context, infeed devices are high-pressure airlocks, blow-through airlocks, pressure vessel systems, nozzle conveyors or airlifts, which KREISEL manufactures in its own workshop. Nowadays, energy reduction and reduction of CO2 emissions play a central role, also when choosing the right pneumatic conveying technology. KREISEL is your expert for pneumatic conveying and is at your side as an expert in the selection of the suitable pneumatic conveying system!

KREISEL DOME VALVES®
The KREISEL DOME VALVE® is a pilot-controlled safety valve. It is used at counter pressures being higher than those for standard valves. Thus they have a positive influence on the planned operating pressure and the system design. The KREISEL DOME VALVE® as a gas-tight isolation valve in pressure vessels was developed in Krauschwitz. The benefits arise from the cross-section being available to 100% in the opening condition. When opening or closing the dome valve, any relative motion between calotte, dome and pneumatically controlled sealing is exlcuded. The sealing is inflated by means of control air and pressed to the dome. Particles of bulk material smaller than 2mm are effectively retained. The KREISEL Dome valve tightly seals against high differential pressures.

KREISEL Airslides
KREISEL Airslides are used for pneumatic conveying of fluidisable bulk materials, such as cement, raw meal, limestone powder or fly ash. This type of pneumatic conveying is very energy-saving. The bulk material is fluidised by means of an aeration fan and transported on the basis of a specific slope of the airslider, which is selected depending on the bulk material. Depending on the customer's requirements, KREISEL supplies the complete air conveyor troughs or just the engineering for local production. KREISEL airslide diverters allow the bulk material flow to be divided.

KREISEL Dosing system
The KREISEL Dosing system was designed to feed fuels such as pulverised lignite, pulverised hard coal or petroleum coke to burners in a metered manner. The KREISEL dosing system is also suitable for conveying other bulk materials, such as fly ash, limestone powder or bypass dust, in a dosed manner, The KREISEL dosing system DosFeed was developed to meet the high demands on dosed and low-pulsation conveying. The main focus of the development was on a simple design, a long service and a high metering accuracy.

KREISEL Jet conveyor
The KREISEL Jet conveyor can be used with pneumatic conveying systems for conveying capacities < 10 t/h and maximum conveying distances of about 100m. An additional dosing device is not required when using a nozzle conveyor, as the bulk material is continuously drawn into the injector. The use of a Jet conveyor is particularly suitable for very hot bulk materials if other technical options cannot be used.

KREISEL VertiFeed
The KREISEL VertiFeed corresponds to the airlift principle and is used exclusively for the vertical pneumatic transport of bulk materials. Advantages of the VertiFeed are no moving parts in the bulk material flow, which leads to a very high availability, and also the low investment costs. Conveying capacities of up to approx. 1,000 t/h and conveying heights of up to approx. 150 m can be realised. Another advantage is the pneumatic conveying for bulk materials with very high temperatures. The VertiFeed is often used to feed silos or preheaters and also as “Stand-by” machine in the cement industry.
Clearing Rotary Valves
KREISEL rotary valves are used for discharging with constant volume throughput or for volumetric metering of poorly flowing, moist, pasty and sticky bulk material from containers into downstream plant components or conveying systems.
