Highly wear-resistant grate bars for combustion grates in biomass and waste-to-energy plants

Unser Vertikalzerkleinerer schließt das Inputmaterial durch Prallzerkleinerung auf. Ob Elektronikschrott oder Festmist, die Maschine ist universell einsetzbar

The Fall rotary valve can be used for all free flowing goods. The material can be fed from a running material flow, but also from a stockpile, e.g. from a container etc. The material to be filled fills the chambers of the lock rotor coming from above. After rotation of the same, the material falls down out of the rotor chambers. The inlet part is separated from the outlet part by the lock stator, so that different pressures can prevail in both parts, which remain separate in this way.

Application area: The MAHR rotary feeder is used for volumetric dosing of bulk materials. Different cell wheels, combined with speed adjustment, enable fine tuning of the throughput performance. Material: Case + bearing cover: grey cast iron or cast stainless steel Cell wheel: steel or stainless steel partially with Vulkollan sealing strips Special features: The cell wheel has generously dimensioned, permanently lubricated roller bearings which are sealed using radial sealing rings. The enclosed design of the cell wheel and the high precision fitting of the case to the cell wheel guarantee good leak tightness.

Application areas: The MAHR rotary feeders are used for metered discharges of powder bulk materials from silos or containers. Robust cast iron case, cell wheels made of steel or stainless steel, guaranteed quiet running and high operational reliability. Flanged gear motors connected directly via a coupling or using a chain reduction unit are available as drive. Different transmission speeds, variable chain reductions, manually adjustable control gearing or frequency-controlled motors enable fine tuning of the discharge performance. Rotary feeders of the TYPE SZR are suitable for discharge flow rates up to 36 m3/h. Discharge rates to more than 300 m3/h are made possible with the type series N and UL. Design: Cell wheels with 8-10 cells dose the bulk materials; the dosing quantity is determined using the speed of the gear motor. Any change of the dosing quantity can be made using chain wheel alteration, manual control gearing or frequency-controlled motors. Bulk material can be optimally blown out pneumatically in the low pressure range using the blow-out shoe and the leakage air discharge. Material / design: Rotary feeders of the TYPE SZR: with cast iron case and cell wheels for small to medium discharge quantities made of steel or stainless steel. Rotary feeders of the TYPES N + UL: are internally hard chromium plated, with polished cast iron cases and cell wheels made of steel or stainless steel and inclined cells. Sizes 200/620 and 300/650 as heavy-duty welded construction. Silver grey hammer tone paintwork; other painting on request. Technical data: Rotary feeders with motor arrangement above chain wheels enable a short design. Speed monitoring and large-dimensioned motors with temperature monitoring using thermistors guarantee operational reliability. Advantages: permanently lubricated ball bearings quiet running due to inclined cells wear protection due to hard chromium plating

Rotary flow control valve and rotary shut-off valve are designed for use in all industrial areas in which powdery bulk materials are processed, conveyed, stored, distributed, weighed or metered. The rotary flow control valve is responsible for precise and continuous adjustment of the bulk material flow from bins and silos. The rotary shut-off valve is used where quick and reliable shut-off is necessary. The two valves are suitable for material flows from 10 to 1000 m³/h.

creening processes play an important part in the primary industry’s quest for improvement of the end product. Achieving a high level of quality and increased screening yield with low space requirements and energy consumption motivated us to develop the assonic SONIC SPEED SCREEN™ RoSM700 high performance continuous screening machine. Features and advantages at a glance: Optimized screening performance for fine screenings due to screen baskets made of sintered stainless steel mesh or stainless steel screen cloth from 20 – 5,000 μm Elimination of the boundary layer resistances between powder and screen basket fabric Self-cleaning effect (ultrasound and medium frequency) Throughput rate increase by a factor of 1.5 - 10 by ultrasound and lower frequency stimulation of the screen basket Comminution of agglomerates and thus more complete reduction of oversized particles Adjustment to the rheology of the screened product by suitable lower-frequency screen basket stimulation and the use of digital ultrasound generators Easy change of color or product due to pull-out and swivel unit Low space requirement, uncomplicated integration into existing systems Flexible and complete control, possibility of integration into existing control systems Food compliant (EHEDG) and ATEX version (zone 20, 22) available

VKT technology for ROTARY VALVES consists of integrated wear protection INFINITE SHIELD. The wetted surface is completely protected against wear. The ROTARY VALVE may also be coated with INFINITE SHIELD or welded on hard. Housing and rotary star are grinded with precision to measure and thus ensure a very good air seal and long life.

Rotary valves are designed for use in all industrial areas in which powdery bulk materials are processed, conveyed, stored, distributed, weighed or metered. The REEL Möller Rotary valve is the right choice if you would like to have a controlled discharge out of the silo or hopper or if you would like to have a controlled feeding to a jet conveyor. Typical bulk materials are fly ash, alumina, cement, lime, gypsum, minerals like copper concentrate etc. with a density from 0,5 to 2,0 t/m³
