Figure 9.10.1.1-1. The cane is received at the mill and prepared for extraction of the juice. At the mill, the cane is mechanically unloaded, placed in a large pile, and, prior to milling, the cane is cleaned. The milling process occurs in two steps: breaking the hard structure of the cane and grinding the cane. Breaking the cane

source. Emissions are also generated from other material handling operations. At some sinter plants, these emissions are captured and vented to a baghouse. 12.5.2.2 Blast Furnace - The primary source of blast furnace emissions is the casting operation. Particulate emissions are generated when the molten iron and slag contact air above their ...

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure
Click on the Create Operation icon in the toolbar The Create Operation window will pop up. Make sure the Type of Operation is Mill_Contour There are a set of different subtypes under Mill-Contour, namely Cavity Mill, Z-Level Follow Cavity, Follow Core, Fixed Contour, and so on. These different subtypes are used for different situations and

shell end mills and are recessed on the face to receive a screw or nut for mounting on a separate shank or mounting on an arbor, like plain milling cutters. The teeth are usually helical and the cutter is used particularly for face milling operations requiring the facing of two surfaces at right angles to each other.

Buffing generally requires two operations, a cut buff and a finish buff. Even the cut buff, which is the coarsest buffing operation, is too fine for removal of pits, course abrasive polishing lines, or deep scratches. This is why surface preparation prior to buffing is critical to a …
CENTERING OPERATION Facing operation in the lathe: Facing operation is for making the ends of the job to produce a smooth flat surface with the axis of operation or a certain length of a job. In this operation, 1. Hold the job on Head-stock spindle using Three or four-jaw chuck. 2. Start the machine on desire RPM to rotate the job. 3.
particularly with regard to filtering or drainage operations. Fines content of a kraft pulp may be in the range of 5– 15%. For a groundwood mechanical pulp, the fines content may exceed 40%. Coarseness. This is a measure of the average weight of fiber per unit length, often reported in units of mg/m. It is most conveniently

Machining Operations and Part Geometry Each machining operation produces a characteristic part geometry due to two factors: 1. Relative motions between the tool and the workpart •Generating –part geometry is determined by the feed trajectory of the cutting tool 2. Shape of the cutting tool •Forming –part geometry is created by the
operations and that is not too large to be moved from one work site to another. The engine lathe (Figure 7-1) is ideally suited for this purpose. A trained operator can accomplish more machining jobs with the engine lathe than with any other machine tool. Turret lathes and special purpose lathes are usually used in production or job shops for
The performance of tumbling mills is sensitive to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin-uously optimize mill operation, it is vital to
A tube mill line consists of a number of different pieces of equipment, but the machinery is interdependent. Changing the capacity of any one piece affects the operation of the others. The major factors to consider in a high-frequency tube making line are:
"Ribbed Tube" has a seam protruding on the side of the tube that runs the entire length of the feeder tube. This rib stops at the discharge hole to allow the feed pan to swivel on the tube then, the rib continues to the next hole and so on. The rib is there for 2 reasons. First it prevents the pans from sliding away from the discharge hole.
