Our products sell well all over the world,and have advanced technology in the field of crushing sand grinding powder.
Sand maker is suitable for the crushing of soft, hard and extremely hard material and reshape of those products.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
Jun 17, 2005· Double thespeedof the motor and you double thespeedof theconveyor. The motor turns at 1800rpm. This is reduced through a gearbox to 60rpm. The circumference of the end drive is about 1foot(4" X pi) and so a point on that moves through 60feetperminute. As the belt moves at thatspeedit alos move at 60feetperminute.

At 60hertz(base motorspeed), both HP and torque are at 100 percent. When theVFDreduces frequency and motorspeed, it also reduces voltage to keep the volts/hertzratio constant. Torque remains at 100 percent, but HP is reduced in direct proportion to the change inspeed. At 30hertz, the HP is just 50 percent of the 60-hertzHP.Online Chat
Apr 09, 2015· That means for eachHzofspeedfrom theVFD, the load shaft moves .1Hz, and at 1m circumference, theconveyor speedwill be 0.1m/second, x 60sec./minute= 6m/minute, x 60min./Hr = 360m/Hr = .36kM/Hr. So the factor to go from 1Hz to .36kM/hr is (.1 x 60 x 60)/1000 or .36, so if you enter .36 into A099, the display, and the outputspeed, will be ...Online Chat

Re: How to convertFeetperMinute(FPM) toHertz? Thehertzwill vary but nominally it is 60Hz. I just need the relationship between the two that also includes the gearbox. Thehertzis variable by the use of an inverter to increase or decrease thespeedof the chain. The motor is 1760RPM but the output is changed by the gearbox ratio of 34.45.Online Chat

How to converthertzto revolutions perminute[Hzto RPM]:. f RPM = 60 × fHz. How many revolutions perminutein ahertz: If fHz= 1 then f RPM = 60 × 1 = 60 RPM. How many revolutions perminutein 77hertz: If fHz= 77 then f RPM = 60 × 77 = 4 620 RPM. Note:Hertzis a metric unit of frequency.Online Chat
For Example: A four polethree phase induction motorwhen operated at 60Hzwill be very close to 1800RPM(synchronousspeed).The rated full loadspeedwill be less than synchronousspeedby the value of Slip.A four polethree phase induction motorwith a ratedfull loadspeed of 1750 has a slip rating of 2.7%.By formula:Online Chat
Calculatingconveyor speedin FPM is actually quite easy. Divide the number of containers perminuteby the number of containers perfootto get linespeed in feetperminute. Company A linespeed= 200 CPM / 1 CPF = 200 FPM. Company B linespeed= 200 CPM / 2 CPF = 100 FPMOnline Chat
Apr 02, 2010· Thespeedof the motor changes in direct proportion to thehertz. Thus, a four-pole motor running at 45hertzwill turn 1,350 rpm, and a six-pole 1200-rpm motor at 40hertzwill run 800 rpm. A motor can be sped up, also: a four-pole motor running at 90hertzwill turn 2,700 rpm. MostVFD’s come with a preset limit of 60Hz.Online Chat
When Enercon sizes a cap sealing system for an application we rely on theconveyor speedexpressedin feetperminute(FPM).

The third way to monitorconveyor speedis to attach an encoder to an encoder measuring wheel that rides on the surface of the belt or one of the rollers if the belt itself is crowded with product. Typically, these wheels are 1footin circumference, which makes an easy conversion from RPM to linearspeed in feetperminute.Online Chat
