Final assembly of senders for pneumatic conveying systems

Gentle and safe transport of toxic NMC powders

Gericke has delivered multiple dense phase pneumatic transport systems for the gentle and safe transport of fine toxic NMC powders used for the battery production.
For the production of rechargeable batteries cathode material, typically fine lithium nickel manganese cobalt oxide (NMC) powders are utilized. For a global chemical company Gericke delivered multiple pneumatic conveying systems to unload the powders from IBC and to convey to further production processes placed up to 50m away from the unloading point.

Abrasive powders

NMC powder usually has a high bulk density larger than 1.5 kg/l and are considered abrasive. Due to the abrasive character a low velocity dense phase conveying system was chosen against a lean phase conveying system to minimise wear effects in the conveying line. With the Gericke PulseFlow ® PTA conveying system a pressure vessel is used for transporting the powders as slowly moving product plugs.

Wear protective coating

No contamination coming from metallic wear is accepted in the powder because it could cause later a short circuit in the battery. Therefore, the complete conveying system (pressure vessel, its accessories and pipeline) was equipped with different kind of wear protection coating.

Hygroscopic

The powders are very sensitive to moisture and thus dried air must be utilised for preventing the powders to form lumps. With the Gericke PulseFlow ® PTA system a high solids loading can be achieved, which minimises the consumption of pressurised gas and finally reduces the energy consumption for the production of compressed and dried air.

Carcinogenic and toxic

The pressure vessel and its elements are gas and dust tight and monitored regularly. Therefore, the environment and operators are protected against the carcinogenic and toxic nature of the NMC powder allowing a safe and clean workplace.

More Innovative Rotary Valve Engineering
For many years Gericke RotaVal has continuously improved its range of rotary valves. Designed and manufactured in the UK, fast clean modular range valves have been delivered to a worldwide customer base in various industries. These rotary valves offer clever and innovative solutions that protect the production process and reduce operating costs. Rotary valves are often seen as a commodity. But they play an essential role in many bulk handling processes, often even as a safety device. Therefore, it is important that the owner or manager of a plant is also considering the operational and design aspects of such a valve. Reduced Life Cycle Costs Thanks to Tapered Bore Extractable versions of rotary valves facilitate the cleaning and inspection process. But with the very small gap between the rotor and the housing, the opening and closing of a valve always involves the risk of the rotor touching the housing. The tapered bore design used by Gericke RotaVal eliminates

Gericke Mixers are now even more energy-efficient
Saving energy is a key pillar of a sustainable production environment. With the introduction of highly efficient IoT drives for its GMS batch mixers, Gericke supports their customers in achieving their ambitious goals. GMS mixers The proven GMS mixers are now combined with a highly energy-saving workhorse: a new, very efficient drive, based on a permanent magnet motor. In these motors, the magnetic field is on one side created by a permanent magnet, which offers several key advantages. Strong and efficient The delivered torque is constant over the entire speed range, which makes these motors ideal for batch mixers that start and stop frequently. Since the magnetic field only needs to be built up on one side, the efficiency of the motors is significantly higher than that of asynchronous motors. The international energy rating for such a motor is “ultra premium efficiency” (IE5). In addition to the higher rating, the high torque that can be delivered also indirectly reduces energy consumption, as the motor does not have to be oversized for the start-up. Compact and quiet Space limitations are often seen in a production plant, especially when an existing installation needs

Continuous dense phase pneumatic conveying with limited height
Twin vessel dense phase conveying is the solution when minimal height is available and when at the same time the product needs to be conveyed gently without any creation of fines. A customer had major issues with a belt conveyor that should transport the instant chocolate drink powder from production to a sieve placed right above the filling lines. The installed belt conveyor contaminated the powder with wear which was not acceptable. Because all upstream equipment was already installed, less than 1 m below a discharge rotary valve was available. A lean phase pneumatic conveying system with negative or positive pressure would have been possible. However, because the powder must be treated very gently minimising the creation of fines during the transport, a low velocity dense phase conveying system Gericke PulseFlow PTA with two vessels was selected. The two 20 l pressure vessels were placed side by side and successfully fitted below the continuously discharging rotary valve. The chocolate powder is fed at a rate of 1.5 t/h into one pressure vessel while the other vessel is conveying and alternating. This mode generates a continuous product

Gentle and energy-efficient pneumatic conveying systems
As a supplier of all types of pneumatic conveying system types, Gericke can always offer the solution best suited, also considering the energy consumption and process safety. Pneumatic dense phase conveying is among the gentlest solutions and is often the only technology suited to transport large product volumes efficiently and hygienically without demixing. It enables low-abrasion transport as well as complete emptying of the conveyor pipe. Additionally, it reduces maintenance costs and energy consumption. Gericke is a global market leader in the design and delivery of such systems. Bulk handling is a major cost factor in the production process but can be well automated. So choosing the right system is crucial. Since the 1940s, Gericke has been a pioneer in the development of pneumatic conveying systems. Customers benefit from this experience. Gericke technology enables the conveying of a wide variety of goods over short and long distances. Dust tight Pressure vessels are utilised within pneumatic dense phase conveying systems to introduce the bulk solids into the pipeline and to control the pressure difference. Contrary to when using
