Zirkoplex ZPS

Zirkoplex ZPS

Application universelle pour les matériaux jusqu’à une dureté Mohs d’environ 3,5, avec des exigences de finesse finale très élevées et un apport énergétique extrêmement faible.

  • Broyeur sélecteur pour des finesses élevées, un broyage à froid et des paramètres de production flexibles dans la plage de finesse inférieure à 5 µm à 200 µm
  • Broyeur à percussion à sélecteur Turboplex intégré dans la partie supérieure pour une limitation exacte des grains
  • Construction soudée
  • Outils de broyage en acier spécial

Principle of operation

The size-reduction elements comprise an impact beater unit plus a stationary triangular-ribbed grinding track that surrounds the grinding chamber. The impact beater unit is designed such that the grinding process is very efficient. The impact beaters are exchangeable; the grinding track is in segmented design. A Turboplex ultrafine classifier with one or more horizontal classifying wheels is integrated into the top section of the mill. 

The feed product, charged to the machine by a system-sided feed unit, enters at the filling socket and is intercepted by the impact beaters on the beater disc. The combined action of the beaters and grinding track serves to comminute the product, which is then transported via the classifier to the fines discharge. The air introduced into the machine at the air inlet cools, transports and also classifies the product in the integrated classifier. Dependent on the specification, the feed product can also be introduced into the machine entrained in the air. The fines, extracted in accordance with the cut point set at the classifier, exit the machine via the fines discharge. The end product must be separated from the air in a downstream system-sided collection unit.

Particles that are too coarse are rejected by the classifying wheel and are comminuted by the beater unit until they can pass through the classifying wheel and thus correspond to the required fineness as specified by the classifying wheel speed. The feed product enters the classifying chamber from above via a rotary valve, any particles that already display the end-product fineness are discharged immediately by the Turboplex ultrafine classifier without having to pass through the grinding unit. The air is supplied to the mill by a connection on the side of the machine.

Features

  • Optimum accessibility
  • Easy cleaning; a big plus if the product is changed often
  • Designed for processing sticky products that tend to deposit
  • Special fluidisation equipment at critical points
  • Deposit-free and gentle processing of pigments, wax, resins, powder coatings, etc
  • High air flow rate = cool grinding
  • Excellent precision of cut, steep particle size distributions
  • Stable classifying characteristics: once set, the classifying fineness remains constant
  • Explosion-pressure-shock-proof design

Alpine has fulfilled the practice-oriented demands in dry processing for high throughput rates at ultrafine end-product values by using several small turbo classifying wheels of identical size. This multi-wheel concept was applied by Alpine for the first time in Turboplex classifiers. The possibility was thus created of producing superfine products - especially in the range between 3 and 6 µm - with an extremely high fines yield and maximum precision of cut in a particularly cost-effective manner.
