Increased soda production with modern screening machines from RHEWUM
Sodium carbonate is difficult to screen as its hydrophilic properties cause agglomerations. RHEWUM’s high quality sieving technology increases production.
Soda ash is obtained from sustainable production sources, such as the processing of wood. Soda ash is an indispensable raw material in partticular for the glass industry, but also used as a bleaching agent in the chemical industry and not least in the lye of Bavarian pretzels. The demand for high-quality soda ash is high.
The quality of the soda granulate is significantly influenced by the performance, and thus the quality, of the screening machine in use. Soda ash is considered to be a difficult material to sieve, which easily sticks to the screening mesh and tends to form lumps due to its hydrophilic properties. The screening mesh can quickly become clogged and the entire production come to a standstill. Thus, the reliable supply of soda ash for important industrial sectors, and with it the capacity of soda ash producing plants, depends on the screening machine.
With the RHEWUM WA, RHEWUM offers a state-of-the-art screening machine with direct excitation of the screening mesh, whose operational readiness is less prone to agglomeration compared to conventional screening machines. The direct excitation of the screen mesh counteracts the adhesive forces within the material and reduces agglomeration caused by particle adhesion. In addition, all RHEWUM screening machines with direct excitation of the screening mesh have an automatic self-cleaning function:
A strong cleaning impulse, which can be adjusted to the requirements of the respective screening material, periodically ejects the material out of the mesh of the screening cloth without impairing the screening process itself. As a result, there is less maintenance time due to less clogging, and downtimes - which lead to losses in production - are avoided. The higher investment cost in a technically advanced screening machine from RHEWUM is more than compensated for by increased production and improved quality.
For a soda producer who has been working with RHEWUM for a long time, the use of a RHEWUM WA in combination with a RHEWUM feeder, the modern cellular wheel RHEWUM ZR, even led to a long-term increase of the total capacity. Thus, the supply to processing industries, and not least the turnover generated with soda ash, can be significantly increased.
