The world-wide use of Webac plants reflects and emphasizes the success of our installations. Our philosophy bases on the following features:

• Long life through quality of all components
• Flexibility with individual customer solutions
• Consistency with practice-related developments
• Competence with support and attendance also after commissioning of the plants

Research, development and many years of practical experience helped the basic principle of coating to become a perfectly proven process. Special customer demands and a great variety of production tasks show the importance of designing each coating installation in a flexible way and of adapting it to the specific requirements.

The special mixing procedure of the Webac proppants mixer combined with the properties of the resin lead to the highest quality and uniform grain coat.

… lead to first-class quality proppants.

The heart of each coating plant is the Webac proppants mixer. It mixes all the raw materials with the pre-dosed chemicals and executes all the process steps determining the quality of the coated proppants.

Special features of the Webac proppants mixer and, thus, of the complete sand coating plant are:

• High throughput capacities
• Uniform proppants quality
• Economical exploitation of the used raw materials
• To avoid agglomeration the proppants can be cooled inside the mixer

For your coating trials Webac’s scope of supply includes a lab mixer.

Adjustable gas-burners heat the process-air coming from the fans up to temperatures of about 500°C (930°F).This energy is released evenly during the fluidization to the sand within the required time.
