Cement Industry :
Cement as a primary material used for construction has one of the most production rates among industrial products, its application is visible everywhere around us from buildings to bridges and roads. Cement manufacturing companies have got harsh and rough environments as a result of high particle content in the air, which makes a serious requirement for the machinery and systems used in the field to be quite rugged.
Worldwide demand for cement has been growing with modernization and number of companies in the field has always been growing. Without reliable condition monitoring and protection systems cement plant machinery may get involved in problems. VibSens is ready to provide a perfect solution for vibration protection and online condition monitoring of rotary machinery in cement industry including manufacturing, installation, commissioning and training.

Condition Monitoring & Vibration protection: 
Cement companies need to run for long times without a shutdown like 6 months. Condition monitoring & vibration protection of rotary machines enables user to detect and prevent failures before creating downtime. Faults which can be detected by vibration measurement is as follows:

-bearing damage & lubrication problems
-imbalance & misalignment
-looseness, resonance and structural related problems
-gearbox & conveyor belt problems and damage
-foundation movement, coupling damage & inadequate support 

Cement Production Process: 
Cement manufacturing process in many companies is more or less like the one shown below. Steps to manufacture cement is usually as follows: 
• Milling of raw input materials in several stages
• Pyro processing of the raw materials to form cement clinker
• Cooling and storage of clinker
• Final finish milling
• Packaging

Solution for Each Division of Rotary Machines in Cement Industry: 
According to the above, Vibsens has extracted the most important rotary machines used in cement companies and developed the best solutions for condition monitoring and protection systems as follows. Signal outputs from accelerometers installed can be read periodically by VD-5 or continuously by V400 vibration measurement & protection system. Both devices maybe connected (VD-5 offline, V400 online) to computer and transmit data to Vibsens-Pro software which contains monitoring functions like time signal, spectrum, waterfall, orbit etc.In each of the machines mentioned above, certain type of sensors & measurement systems are the correct types based on the importance of the machine role in production, operating conditions and company financial investment which Vibsens is ready to provide solutions based on previous experience with other customers.

Typical online methods layout:
Optional no.1: 
As mentioned as option no.1 customer can select Signal transmitter VC210 A as a vibration transmitter and protection system for all the machinery and measurement points. This scheme has been shown below. 
Image
Optional no.2:
In the second option user can choose V400 which is not only a protection module but also may be used as a condition monitoring system with a very cost effective budget. This scheme has been shown below.

Transducers Location: 
For vibration measurements in horizontal direction, accelerometers are mostly installed on the motor or pump bearing housings nearest possible to the bearings. This enables the user measures velocity of vibrations with one step embedded integrators in mm/sec (RMS) as suggested in ISO 10816 to detect unbalance and structural foundation problems. For measurements in vertical direction, accelerometers are installed mostly on the drive end bearings to enable user to get velocity in mm/sec (RMS) to detect misalignment and looseness. This applies to axial direction measurements, too. For some motors like crusher motors, both drive end and non-drive end bearings are monitored and protected against high vibrations. In gearboxes, vibration of both the input and output bearings are measured.Optional axial vibration measurements could give a proper interpretation of the thrust forces acting on the shaft.

Data Collector Model VD-5:
The VD-5 is a route-based data collector being compact, rechargeable and handheld with a rugged structure. VD-5 Vibration meter has been designed to conform to ISO10816-3 and has one ICP™ accelerometer input to provide accurate single channel vibration measurement. Up to two steps of integrations is embedded in the software application to optionally have the measurement result in acceleration, velocity or even displacement. Device can store up to 4000 time signal frames to transfer to PC with a dedicated software which can calculate spectrum, overall vibrations and some other diagnostic features.

BNC Switch BOX Model SB-6: 
Recommended for walk around data collection routines, where the transducer is fixed and installed. Because changing the direction and point of measurement might affect measurement values, permanently mounted Accelerometers provide more reliable and repeatable readings and the local BNC Switch Box allows for faster, safer and more convenient data collection with portable data collectors or vibration analyzers. VIBSENS switch box works with all 3rd party data collectors and vibration analyzers.
