Titanium Dioxide
Titanium dioxide is characteristically white in colour and is a chemical compound that is used in many different applications.
l As a white pigment for coatings and paints, for colouring plastics and for laminated paper
l As a photocatalyser based on TiO2
l As a food additive (number E171), for example in toothpaste and chewing gum
The production of fine titanium dioxide by means of the sulphate process results in hard clinkers. These clinkers must then be ground to the desired particle size. The aim here is to achieve the most economical grinding process possible with good pigment quality and low energy consumption. The grinding process is realized with several successive steps. The first crushing step plays a key role here, since breaking up the clinkers is energy-intensive and efficient pre-crushing significantly reduces the load on the subsequent steps.
Energy-efficient pre-shredding
Efficient preliminary crushing saves resources and thus represents a significant economic advantage.
For the first size reduction stage, grinding with a high-pressure grinding system, which breaks the clinker with two counter-rotating rollers, has become established in recent years. Compared with the pendulum mill used in the past, this grinding technology is characterized above all by its much lower energy requirement. Another advantage: no grinding aids are needed.
Advantages of the high pressure roller mill
Steep particle size distribution
Low energy consumption
Low wear with abrasive material
Compact installation
No additives necessary
Low noise level
