EQUIPMENT
Silica, or silicon dioxide (SiO2), is a critical material in many applications, from glass and ceramics to cement and abrasives. But the very characteristics that make silica such an industrial success story also make it challenging to process if quality equipment is not selected. The hard, abrasive nature of silica demands heavy-duty equipment designed with these characteristics in mind.
With extensive experience around many forms of silica, FEECO engineers and manufactures the industry’s most rugged, long-lasting equipment. Our custom silica processing equipment is backed by the comprehensive testing capabilities of our Innovation Center, where we can test the processing of silica at batch and pilot scale. We have experience working with the following forms and types of silica:
- Silica
- Silica flour
- Silica fume
- Fused silica dust
- Silica gel powder
MATERIAL PROCESSING
Rotary Dryers
FEECO rotary dryers are the preferred choice for silica drying, offering a robust build, high capacity, and long-term reliability.
Pelletizing Equipment
In addition to our dryers, FEECO can supply custom agglomeration/pelletizing equipment for processing silica and its many derivatives. This includes:
BULK MATERIAL HANDLING
We offer a complete line of bulk material handling equipment both as stand-alone systems, as well as a complement to our processing equipment.
Belt conveyors, bucket elevators, steep incline conveyors, and reversing shuttle conveyors, can all be used to bring seamless fluidity and automation to your silica operation.
Additional equipment such as trippers and plows and belt feeders are available for increasing system flexibility.
PLANT AND PILOT SCALE PROCESS TESTING AND DESIGN
Available in many forms, and with challenging characteristics, testing is often essential in developing production techniques and custom equipment for silica materials. The FEECO Innovation Center is a unique testing facility where we can test your unique source of silica at both batch and pilot scale in order to work out process variables and design commercial-scale equipment, as well as scale up the process.
The FEECO Innovation Center is well-equipped to suit a wide range of testing needs, from de-dusting to pelletizing, and even drying. We can test on a single piece of equipment, or a continuous process loop.
We offer comprehensive testing services in four categories:
Feasibility/Proof of Concept: An initial, non-witnessed batch testing phase in which the possibility of creating a product is explored.
Proof of Product: A more in-depth batch testing phase in which more time is spent determining whether a product can be made to desired specifications.
Proof of Process: A continuous testing phase that aims to establish the equipment setup and parameters required for continuous production of your specific material.
Process/Product Optimization: An in-depth study to optimize your specific material’s characteristics and/or production parameters in an industrial setting.
