new technology, gn vacuum vibrating screen for dewatering - mining stock education

new technology, gn vacuum vibrating screen for dewatering - mining stock education

HOUSTON, Jan. 31, 2021 /PRNewswire-PRWeb/ Traditional vibrating screen only has the vibrating separation function. GN new technology vacuum vibrating screen is a combination of vibrating separation and vacuum separation. The new combined machine improves the dewatering efficiency dramatically.

GN Vacuum Vibrating Screen to Increase Dewatering Efficiency The purpose of using the dewatering vibrating screen is to separate the solid and liquid. In normal condition, the separated solids and liquid will be further treated or used for other application directly. Thus the drier the slag discharged from the vibrating screen, the more liquid will be recovered. In order to increase the recovery efficiency of the liquid, GN developed the vacuum vibrating screen that is a combination of vibrating screen and vacuum unit. By installing a collecting hopper under the last screen of the machine and connecting it to vacuum device to form a certain frequency of vacuum suction on the screen surface with pulsating airflow, the vacuum vibrating screen achieves double separation by vibration and vacuum suction. It increases the recovery efficiency of liquid and reduces the liquid content on discharged solids.

GN vacuum device can be connected to maximum 3 units vibrating screens. It matches with GN single-layer high frequency vibrating screen, tandem deck vibrating screen and parallel deck vibrating screen, etc.

Typical Application of GN Vacuum Vibrating Screen GN vacuum vibrating screen is often used for drilling mud dewatering. In the drilling industry, the vibrating screen is also calledshale shaker. It is used to remove the cuttings in drilling mud to make the mud reusable. The vacuum vibrating screen can greatly increase mud recovery and reduce drilling waste discharge, which is cost saving for driller and environmental friendly operation.

Beside Vacuum dewatering vibrating screen, GN also provides traditional industrial vibrating screen for other application. Industrial vibrating screen is one of GN main series products. It is widely used as dewatering vibrating screen or classifying vibrating screen in environmental protection industry, mining industry, petroleum industry, construction industry and chemical industries, etc. The screen deck is connected with the equipment base via vibrating springs. With the exciting force generated by the vibrator eccentric block during the rotation, the screen deck vibrates along a certain track that is also called vibration mode. GN Industrial Vibrating Screen can achieve linear vibration mode and elliptical vibration mode through different design. According to working condition and customer requirements, GN launched the vibrating screen of following design: High Frequency Vibrating Screen, Tandem Deck Vibrating Screen, Parallel Deck Vibrating Screen and Vacuum Vibrating Screen. In order to get the better separation performance and prevent the screen blocking, GN always recommends the high frequency vibrating screen. GN is able to provide screens with different openings and different materials to meet the requirements of solid-liquid wet screening and solid particle dry screening.

GN Vibrating Screen for Sludge Dewatering Application GN is known as a solution provider of solid-liquid separation or sludge dewatering. Therefore, GN vibrating screen is mostly applied for sludge dewatering. Besides the vibrating screen, GN has some other sludge dewatering equipment like the decanter centrifuge and the screw press unit. In some sludge dewatering project, the solid size distribution ranges from microns to centimeters. The dewatering vibrating screen is always used as the primary separation equipment for coarse solids removing. Normally, to protect the subsequent separation equipment, a dewater vibrating screen for fine solids separation will be installed after the primary vibrating screen to form a step by step sludge dewatering process. According to different type sludge and solids size, GN is able to provide the screens with different openings and materials like wedge wire screen panel, polyurethane screen panel and stainless steel wire mesh screens.

high frequency audio computer monitors may expose screen activity | the best geeks

high frequency audio computer monitors may expose screen activity | the best geeks

It may sound like something straight out of a science fiction movie, but recently, researchers have made a disturbing discovery. Using nothing more than an off-the-shelf microphone, it's possible for an attacker to determine what content you're viewing on your computer monitor.

The researchers tested a variety of LCD screens (with both LED and CCFL backlighting) and observed that the high-pitched noise made by the monitors changed as the content displayed on the screen changed.

The research team tested a variety of methods of recording audio data from the monitors in question, and found that they could capture sufficient data with a few methods. First, a smartphone positioned near the screen, second a compromised smart virtual assistant (like Google Home or Amazon's Alexa), and third, using a parabolic microphone from up to ten meters distant.

Even more disturbing, the researchers discovered that an attacker could correctly identify the website a victim was looking at with up to 97 percent accuracy if the microphone was close to the monitor, and with 90.9 percent accuracy with microphones placed at some distance.

Worst of all, subtle changes in the pitch of your display screen make it possible for hackers to identify what specific characters are being displayed with an accuracy that ranged from 88 percent (more distant microphones) to 98 percent (microphones in close proximity to the monitor). This makes it entirely possible to glean passwords and other sensitive information.

Granted, this is an extremely exotic form of attack that requires a great deal of advance preparation by the attacker. Because of this, it's unlikely that it will see widespread use anytime soon. Even so, it's something that a careful and determined hacker could do right now using off the shelf technology, and there's very little the victim could do to prevent it.

While we're unlikely to see equipment manufacturers take the necessary steps to mask acoustic emanations, robust on-site physical security measures would make detection of this type of attack fairly easy.
