FMS Screen Overview
FMS presents a wide range of vibrating screen types to cover most of sizing/scalping applications in mining industry. Protection of wear protected critical parts beside engineered reliable and efficient design makes an optimal screen design.
Professional design techniques, vibration tests and analysis methods are acquired in order to ensures quality of equipment. FMS products meet the highest quality test. FMS screens use bolted connections to eliminate stress points and improve structural rigidity.
FMS Screen Technology
FMS Horizontal screens are heavy duty type, utilized in a wide range of applications such as mill discharge screening, coal preparation, and wet sizing. Inclination of 0-10° is usually suggested for this type of screen.
2.Double slope / Banana screen
This type of screen has been manufactured up to the capacity of 1440 tph with 2.5 x 8.5m screen area. Single, double or t Q Pellet de-dusting screen
3.Pellet de-dusting screen
Proper material motion, large screen area, shape of media opening and wear resistance material for media are the main characteristic of pellet de-dusting screens. Screen area up to 2.5x9 m with 400 tph has been designed and worked successfully riple deck design can be provided for such high efficiency screens .
Inclined screen usually suggested for scalping applications due to the lower manufacturing cost comparing linear motion screens. Screens up to 2.4x7.2 m dimension, 2000 tph capacity and 8o/o material humidity has been manufactured. The vibrating double raw self-aligning bearing type and no contact grease sealing system is utilized to maximize the bearing life time.
For application with 90°/o water content in feed and desired discharge with below 15°/o moisture, dewatering screen is suggested. This screen has negative slope, 1500 rpm vibration frequency and capacity up to 50tph.
High screening efficiency with minimum of maintenance cost are the main options considered in FMS washing screens. In addition, special water nozzle are used for higher washing performance.
Linear-motion screens manufactured for heavy-duty pre-screening of fine materials before primary crushing. Grizzly screens have the robust design to bear feed stones up to 1 mm size.
8.High temp screen
High temp screens are designed to bear feed materials, like sizing traveling grate discharge, with max 1000° C temperature. Special wear resistant media, cooling system for exciter and heat protection of electrical motor is considered in design.
Professional Design Procedure
FMS simulate and analyzes mechanical behavior and material classification process under vibration. Screens are engineered by integrating finite element analysis (FEA) method into the design procedure to ensure the proper design. FEA provides information such as dynamic stress analysis, natural frequencies and harmonic responses in modal analysis. The final purpose of this analysis is the optimization of vibrating screen's components in order to guarantee stress and strain levels that avoid early fatigue failure. Drive and suspension systems are designing by means of FMS design software. Simulation of material behavior is performed by professional DEM software.
FMS Screen feature
Each machine is tested using a vibration analyzer to find any dynamic irregulates in a vibrating screen. This information makes it possible to monitor the orbit diagrams, amplitude and frequency of vibration and FFT analysis. The integrated FFT analysis separates and analyzes frequency patterns that indicate possible mechanical problems.
Two types of vibration tests are performed:
- Regular tests: control the performance of screen and feeder via analyzing the dynamic behavior of machine and material distribution. All vibrating screens are tested before shipment .
- Troubleshooting: locating and eliminating unwanted vibration sources that a has detrimental effect on the machinery process.
