Selecting a Belt Grinder 2×72 belt grinders are the most popular size among professional knife makers. The belt grinder belt speed typically runs double from what the belt speed of the belt of a belt sander is running at. “The Toronto Blacksmith 2×72 Belt Grinder is made in Canada and avoids those issues. -Aluminium wheels. 2” Idle wheels, 3” Tracking wheel, 4″ Drive wheel with 5/8″ bore -Standard quick-change 1.5″ tooling arm.
Jason has been using Red Label’s EdgeCore Ceramic belts for some time now. Jason has found that the EdgeCore belts have an impressive lifespan when compared to more expensive brands he has used in the past. Red Label’s EdgeCore Ceramic belts were specifically designed for aggressive, high pressure grinding on steels, hardwoods, and many other materials.
Thumbing thru the channels last week and caught the last few minutes of Forged in Fire on the History Channel. “Travis is a degreed engineer that improved on the 48” or xx inch belt grinder. There are several informative videos of the finer points of knife grinding with his machine.

What speed should a belt sander be?
The optimal speed for belt grinders is largely dependent on a number of factors, including type of abrasive grain, grit grade, workpiece material, and more. Generally speaking, a safe speed in most cases is 3,000 surface feet per minute. You can calculate surface feet per minute using the formula SFPM = RPM X .
What is a knife grinder?
Definition of knife grinder 1 : one that grinds knives: such as. a : an itinerant tradesman who sharpens knives or other edged tools. b : a device (as a grindstone or emery wheel) used for grinding or sharpening knives or other edged tools.
How do you find the linear speed of a belt?
A conveyor speed, or in this case the linear belt speed, can be calculated using the formula pi/2*D*RPM/60. In this formula, D is diameter and RPM is the rotations per minute of the conveyor. The value is then divided by 60 to convert the speed into distance per second.
How do I determine my belt speed?
Calculate the belt velocity by multiplying the circumference of the pulley by the speed of the pulley. For example, the drive pulley has a circumference of (Pi)(D2). This equals 2(Pi). The speed of the pulley is 1,800 rpm.
What is the difference between a belt sander and a belt grinder?
The belt grinder belt speed typically runs double from what the belt speed of the belt of a belt sander is running at. Belts grinders you generally have multiple grinding points such as the platen and the second grinding point is the contact wheel.
What is a zero grind?
A zero grind has no secondary bevel. So there is no “blending” two areas of a grind, as primary grind IS the edge. A scandi grind is probably the most common example of a zero grind, but almost any grind can be “zero” if someone wanted it to be.
Who invented the knife sharpener?
Howard Ray Longbrake, Knife Sharpener, LoRay Inventor.
How fast can a conveyor belt go?
BELT MOVES AT SPEED OF 65 FEET PER MINUTE (FPM) Conveyors move boxes at about the same speed as a person carrying them. This is about 65 feet per minute (or about 3/4 of a mile per hour).
How do you calculate RPM for conveyor belt?
Measure the revolutions per minute of the rollers. Count how many full rotations are made by the roller in one minute. Multiply the RPM by the circumference of the roller. This calculation provides the linear distance traversed by a point on the conveyor belt in one minute.
How do you calculate the TPH of a belt conveyor?
CAPACITY (TPH) = . 03 x Belt Speed (FPM) x material weight (lb. per cu. ft.)
Does a bigger drive pulley increase speed?
Pulley systems entail two pulley wheels on a shaft joined by a belt. These wheels are driver and driven pulleys. By changing the diameter of the pulley wheels, speed can be changed. A smaller pulley turning a larger pulley results in the larger one moving more slowly but with more shaft power.
What does a smaller pulley do?
If a smaller pulley turns a larger one, the larger one will turn slower, but with more power available at the shaft. If a bigger pulley turns a smaller one, the smaller one will turn much faster than the bigger one but with less power available at the shaft.
