The shell of a rotary dryer is usually constructed by welding rolled plate, thick enough for the transmission of the torque required to cause rotation, and to support its own weight and the weight of material in the dryer. The shell is usually supported on large tyres which run on wide rollers, as shown in Figure 16.10, and although mild steel is the usual material of construction, alloy steels are used, and if necessary the shell may be coated with a plastics material to avoid contamination of the product.

Carbon steels are the most widely used materials of construction. Unalloyed carbon steels typically contain nominal amounts of manganese, silicon, phosphorus, and sulfur. They are normally supplied with a pearlitic-ferritic microstructure (see Figure 21.3) produced by air cooling a hot-formed product (e.g., hot-rolled plate) or by a normalizing heat treatment. They are available as either killed carbon steel or plain carbon steel.

Alignment of the anti-roll plate is important to obtaining good sections. Adjust the handle on the anti-roll plate back into position. It should be exactly parallel to the knife edge. As sections are cut, they will slide under the anti-roll plate keeping them flat (Fig. 4.4f). Lift the plate and use a small paint brush to handle the section. To keep the section flat, use the brush to press the section down on the knife. Some people section without the anti-roll plate and use the paint brush to keep the sections flat on the knife (Fig. 4.4 g). 

To pick up the sections, have a slide ready at room temperature. If used, rotate the anti-roll plate out of the way. Orient the slide with the bottom of slide closest to the knife (Fig. 4.4 h). Slowly lower the top of the slide to touch the frozen section and it will thaw on the microscope slide (Fig. 4.4i). Additional sections can be put on one slide if needed. Usually more than one section or even a ribbon of sections is cut for each slide. This increases the chances of having at least one good section per slide. Most importantly, this reduces the number of slides that need to be processed for immunocytochemistry. Finally, remove the O.C.T. from around the sections. With a fine pair of forceps (EM 3C or EM 5) pick an edge of the dried O.C.T. and pull it down the slide to the opposite end of the section (Fig. 4.4j). The sections will remain on the slide and the thin transparent O.C.T. will peel off. In Fig. 4.4j, the section indicated by the white arrows still has dried O.C.T, while the small circular sections to the bottom have the O.C.T. removed. Sections on slides can be stored in a -20°C frost-free freezer for an extended period of time. Sections stored for several years have been thawed and used successfully.

This tissue was frozen in a rectangular mold, (b) The chuck with the tissue is placed in the arm. (c) The excess O.C.T. is trimmed off with a razor blade by cutting into the block several times, (d). The trimmed frozen O.C.T. is removed with a razor blade cut from the top of the block, (e) The knife is adjusted into position very close to the block, but not touching. The block is advanced toward the block until sections are cut. (f) The anti-roU plate prevents cut sections from curling, (g) An alternative to the anti-roll plate is to use a fine paint brush to hold a section as it comes off the block, (h) Sections are picked up on microscopes slides, (i) Lower the bottom of the slide until the section attaches then warm the slide, (j) When the section is dry, remove the dried film of O.C.T. arrows) with a forceps. Note the two rows of sections toward the slide label down) have the film already removed...

To pick up the sections have a slide ready at room temperature. Frequently, set the microscope slides on the open glass door of the cryostat. Leave the microtome arm at the bottom of its travel. If used, rotate the anti-roll plate out of the way. Orient the slide with the bottom of slide closest to the knife. Slowly lower the top of the slide to touch the frozen section. The section will jump onto the microscope slide and it will thaw on the slide. Additional sections can be put on one slide if needed. Usually more than one section or even a ribbon of sections is cut for each slide, reducing the number of slides that need to be processed for immunocytochemistry. 

Shell and baffles. Shell diameters are standardized. For shells up to and including 23 in. the diameters are fixed in accordance with American Society for Testing and Materials (ASTM) pipe standards. For sizes of 25 in. and above the inside diameter is specified to the nearest inch. These shells are constructed of rolled plate. Minimum shell thicknesses are also specified.

Almost 85 % of aluminum is used for wrought products such as rolled plates, foils, and extrusions [16]. Cast aluminum alloys provide cost-effective products but usually have lower tensile strengths than those of wrought alloys. Aluminum alloys are used in engineering, the aerospace industry, and for components where corrosion resistance or light weight is needed. If left unprotected their surfaces are anodized, which means that they form a white protective layer of the corrosion product, aluminum oxide.
