A system and method for feeding a high volume of low-bulk-density and pressure-sensitive feedstocks into a pressurized environment. The system includes a lock hopper filling system, one or more lock hoppers, a feed bin, and a feeder. The methods involve using such a system to feed bulk materials into a pressurized environment by feeding bulk material from a low pressure into the surge bin, filling the one or more lock hoppers from the surge bin, operating the lock hoppers, and discharging lock hoppers into feed bin, and discharging feed bin into the high-pressure zone using feeder.

A secondary silo on a second portable frame is independently portable relative to a primary silo and a vertical conveyor on a first portable frame. The vertical conveyor conveys flowable proppant material from an intake hopper below the primary silo into either one of the silos. The silos have gravity discharge chutes that are gravity fed directly into a proppant blender unit. An unloader on wheels is self-propelled and steerable relative to the silos. The unloader can be lowered relative to the wheels to sit on the ground to allow vehicles to drive over the unloader for discharge. Intake hoppers of the unloader can be raised up against the vehicle to form a closed duct discharging from the vehicles into the unloader. A discharge of the unloader forms a closed passage with the intake hopper of the vertical conveyor.

A vibratory drum includes a tubular drum having a longitudinal axis, and first and second vibratory generators disposed laterally relative to the longitudinal axis and opposite each other across the tubular drum. The drum also includes a frame to which the first and second vibratory generators are attached; and a plurality of resilient elements attached at a first end to the tubular drum and at a second end to the frame, whereby the vibratory motion of the generators is transferred to the tubular drum to impart a circular motion to material disposed in the tubular drum.

The present invention relates to a pneumatic air booster, and provides a pneumatic air booster, which: can minimize the amount of air supplied to a pipeline, through which objects move, of high-density transfer equipment for transferring heavy objects with high specific gravity such as sand and limestone in a blower, a compressor or the like; enables smooth transfer of the objects in the pipeline and reduces even the impact to the pipeline so as to be advantageous in maintenance and repair of equipment; and is independently operated when the air booster is applied to a pneumatic conveying system, so as to enable pressure adjustment of the pipeline, so that a monitoring and control system is simplified, and thus costs for constructing the system can be reduced.

A bulk finishing system including a plurality of liquid immersion workstations defining a finishing process for a plurality of metal work pieces processed therethrough. Each of the plurality of liquid immersion workstations includes a tank, and the plurality of metal work pieces are conveyed through a group of one or more of the respective tanks of the plurality of liquid immersion workstations by non-contact magnetic conveyance provided by an inclined downstream tank end wall forming a work piece exit slide, with a magnetic conveyor extending along an exterior side of the inclined downstream tank end wall. The plurality of work pieces are introduced loosely in bulk to each one of the group of tanks of the plurality of liquid immersion workstations.

A vibratory apparatus includes a deck, an electro-mechanical sensor and at least one vibratory exciter. The deck has an upper surface configured to receive items to be conveyed in at least a first direction along a longitudinal axis from a first deck end to a second deck end. The electro-mechanical sensor includes a wheel disposed above the upper surface of the deck, the wheel being rotatable about a wheel axis disposed transverse to the longitudinal axis, and an electronic sensor associated with the wheel, the electronic sensor configured to generate a signal representative of the revolutions per unit time of the wheel. The at least one vibratory exciter is attached to the deck and is configured to move the material along the deck.

A conveying device for conveying bulk material, comprising products and product breakage thereof, in a conveying direction has a first conveying element and a second conveying element which is arranged downstream of the first conveying element, with the result that a gap is formed between the first and the second conveying element. A covering element is arranged above the gap. The gap has a first width according to a predefined separating criterion in such a way that the passage of product breakage through the gap is allowed and the passage of products through the gap is prevented.

A paddle conveyor system for efficiently removing tare, dirt, small particles, and other debris from large bulky products such as sugar beets. The paddle conveyor generally includes a first pulley including a first side and a second side and a second pulley including a first side and a second side. A first linkage is connected between the first side of the first pulley and the first side of the second pulley and a second linkage is connected between the second side of the first pulley and the second side of the second pulley. A plurality of paddles is each connected between the first linkage and the second linkage such that the plurality of paddles forms a loop for conveying a material towards the second pulley. Each of the paddles includes one or more slots through which debris from the material may fall.

Provided are a raw material discharge device, a method of processing an electronic and electrical device component scrap, and a raw material discharging method of an electronic and electrical device component scrap, which are capable of efficiently discharging the raw material having various shapes, specific gravities and shapes in each fixed amount. A raw material discharge device including: a storage unit 1 which stores a raw material and comprising a discharge port 11 at one end; a discharge unit 2 arranged at a bottom surface 15 of the storage unit 1, which conveys the raw material toward the discharge port 11 and discharges the raw material to an outside of the storage unit 1; an adjustment unit 3 including a plurality of struts 31 extending from above to below the discharge unit 2 and adjusting an amount of the raw material to be discharged by holding a part of the raw material with the struts 31; wherein a ratio (d1/d2) of a distance (d1) between a strut 31 closest to a side surface 13, 14 of the storage unit 1 and the side surface 13, 14 of the storage unit 1 to a narrowest distance (d2) between the struts 31 in a center portion of the storage unit 1, and a ratio (H1/H2) of a height of the strut 31 closest to the side surface 13, 14 of the storage unit 1 from a floor to a minimum height (H2) of a strut 31 which is other than the strut 31 closest to the side surface of the storage unit 1 from the floor are respectively adjustable so as to prevent clogging of the raw material being discharged to the outside of the storage unit 1.
