The GD and 2D hammer mills are designed for the animal feed industry, to grind raw materials into small particles and meal. Both the GD and 2D hammer mill series cover capacities ranging from 5 – 100 tons per hour, dependent on type of raw material, formula and required grinding structure and can be incorporated in a pregrinding as well as a post grinding system as a complete grinding

Turning operations remove material from a rotating workpiece by feeding a singlepoint cutting tool axially, along the side of the workpiece. Calculations use the desired cut diameter, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.

Where Vm = Volume of metal removed per grinding time (in. 3 /min). Wheel wear and metal removal were measured in each test to calculate a G ratio. A Q´ value of 0.167 was used and the horsepower draw was measured in order to calculate the U value. During each test, researchers removed 0.500 in. from the diameter of the workpiece.

Production Time Calculator. The production time for a manufacturing process is primarily determined from the cycle time, but must also account for the defect rate, machine uptime, and machines used. Using these parameters, the run quantity, run time, down time, total production time, and production rate (parts/hr) will be calculated.

5.3 GRINDING FORCES, POWER, AND SPECIFIC ENERGY. Forces are developed between the wheel and the workpiece owing to the grinding action. For plunge grinding operations, as illustrated in Figure 52 for straight surface and external cylindrical grinding, the total force vector exerted by the workpiece against the wheel can be separated into a tangential component F t and a normal component F n.
