Ro­tary valves for grind­ing a range of ma­te­ri­als

What requirements do rotary valves need to meet?
Ex­plo­sion pro­tec­tion is re­ally im­por­tant to us be­cause we trans­port ma­te­ri­als at risk of ex­plo­sion in our sys­tems. Our re­quire­ments cover Zone 20 (21) in in­ter­nal ar­eas and Zone 22 in ex­ter­nal ar­eas.
Our sys­tems also en­sure an ex­plo­sion pres­sure shock re­sis­tance level of 0.4 bar. The ro­tary valves in them are con­fig­ured for lev­els higher than this, which means that they eas­ily meet our de­mands. This gives us the se­cu­rity of know­ing that am­bi­ent air is kept com­pletely iso­lated from down­stream con­tain­ers, al­low­ing us to main­tain qual­ity stan­dards.
Ad­di­tion­ally, our con­veyed me­dia reach tem­per­a­tures of up to 45 de­grees Cel­sius and we need to process as much as 60 tonnes per hour. Scheuch COM­PO­NENTS has what it takes to ac­com­mo­date all these re­quire­ments with ease.

What tasks do rotary valves perform in your systems?
Our grind­ing mod­ules op­er­ate in a neg­a­tive-pres­sure en­vi­ron­ment, which means that a vac­uum process takes place in the ham­mer mill. Be­cause of this, it is ex­tremely im­por­tant to pre­vent any ex­ter­nal air from get­ting into the con­tainer – oth­er­wise, the as­pi­ra­tion process in the mill will not work prop­erly. In ad­di­tion to main­tain­ing an air seal, the ro­tary valves play an es­sen­tial role in en­sur­ing ef­fec­tive de­cou­pling.

Why did you opt for Scheuch COMPONENTS?
It was the ex­cep­tional value for money that first per­suaded us, and we were also im­pressed by how quickly the com­pany was able to han­dle our en­quiries. The Scheuch COM­PO­NENTS team con­sis­tently proved them­selves to be ef­fi­cient and en­gaged, en­sur­ing that our pro­jects were able to progress smoothly. It’s es­pe­cially im­por­tant to men­tion our ex­pe­ri­ence with Mr Lang, who showed ex­cep­tional ex­per­tise and pro­fes­sion­al­ism. His spe­cial­ist knowl­edge and ad­vice helped us iden­tify the very best so­lu­tions for our needs. Last but not least, the rel­a­tively fast lead times were an­other sell­ing point. Over­all, we are ex­tremely happy with our choice and have greatly en­joyed work­ing to­gether.

Are you planning any other projects involving Scheuch COMPONENTS?
Def­i­nitely! Scheuch COM­PO­NENTS is our num­ber-one choice, so we’ll be re­turn­ing there for more quotes in the fu­ture. At the mo­ment, we are work­ing on a pro­ject in­volv­ing a ra­dial fan and are hop­ing to es­tab­lish an­other suc­cess­ful part­ner­ship with the com­pany here too.
