Vertical lift

FIG. 12-33 Cocurrent gas-solids flow in a vertical-lift dilute-phase pneumatic conveyor. [Pg.1174]

In most change-can mixers, the mixing elements are raised from the can by either a vertical lift or a tilting head in others, the can is... [Pg.1643]

Bucket elevators are the simplest and most dependable units for making vertical lifts. They are available in a wide range of capacities and may operate entirely in the open or be totally enclosed. TFe trend is toward highly standardized units, but for special materials and high capacities it is wise to use specially engineered equipment. Main variations in quality are in casing thickness, bucket thickness, belt or chain quahty, and drive equipment. [Pg.1918]

A second type of control required is that of the package or pallet itself as it is handled by conveyors and other equipment. This handling may consist of right-angle transfers in a vertical lift or of a set of restrainers on the sides of a belt conveyor. [Pg.1975]

Various furnace movements must be accommodated by the enclosure. Operations such as furnace tilting for tapping and slagging, electrode vertical lift, and direction of furnace roof swing must be coordinated with respect to enclosure shape and the location of the exhaust off-take. [Pg.899]

Where a vertical lift is required, the most widely used equipment is the bucket elevator, consisting of buckets fitted to a chain or belt which passes over a driven roller or sprocket at the top end. Bucket elevators can handle a wide range of solids from heavy lumps to fine powders and are suitable for use with wet solids and slurries. [Pg.148]

The proper design of sumps for the use of vertical lift pumps or horizontal pumps taking suction from a sump is important to good suction conditions at the pump [2, 3,14]. [Pg.212]

Lift Check Valves These valves (Figs. 10-160 through 10-162) are made in three styles. Vertical lift check valves are for installation in vertical lines with flow normally upward. Globe (or piston) valves with a 90° bonnet (Fig. 10-161) are for installation in horizontal lines, although inclined bonnet versions (approximately 45°) with spring... [Pg.98]

When conveying plastics a properly designed system is to take the shortest distance. The shortest distance between two points is a straight line. The maximum conveying distance is usually 800 equivalent ft (244 m). A gradual upward slope is never better than a vertical lift. When the plastic passes through a 45° or 60° elbow, it ricochets back and forth creating turbulence that destroys its momentum. [Pg.555]

Compute the elevator height. To allow for satisfactory loading of the bulk material, the elevator length is usually increased by about 5 ft (1.5 m) more than the vertical lift. Hence the elevator height is 75 +5 = 80 ft (24.4 m). [Pg.246]

This rise must be included in the vertical lift power input computation. When the tripper is driven by the belt, allow 1 hp (0.75 kW) for a 16-in (406.4-mm) belt, 3 hp (2.2 kW) for a 36-in (914.4-mm) belt, and 7 hp (5.2 kW) for a 60-in (1524-mm) belt. Where a rotary cleaning brush is driven by the conveyor shaft, allow about the same power input to the brush for belts of various widths. [Pg.249]

Built-up films have been obtained by the vertical lifting method at room temperature with a 105 type LB trough. The IR spectra were recorded on a Nicolet FI-IR spectrometer, the UV-Vis spectra were measured using a Perkin-EImer 330 spectrometer whereas the SAXD measurements were performed on a D/Max-rA X-ray diffractometer (CuKa radiation with A = 0.15405nm). The AFM images were obtained on an SAP 400 (Seiko Instrument Inc.) microscope. [Pg.415]

Motorized rake-hfting devices typically are designed to allow for a vertical lift of the rake mechanism of up to 90 cm (3 ft). [Pg.2010]
