A trim chute for a loading apparatus for loading particulate material into a container, the trim chute being configured to be engaged with the loading apparatus to direct particulate material into the container, the trim chute being moveable with respect to the loading apparatus during loading, movement of the trim chute effecting a change in flow of the particulate material into the container.

A compact modular mobile aggregate processing system configured with no stand-alone inter-plant conveyors for decreasing the footprint of the system and an infinitely adjustable flow diverter(s) for increasing the control of and variation of output characteristics of the system; the system further including specialized folding conveyors.

Some examples described herein include a flexible hopper for a conveyor system. The flexible hopper may include a hopper weldment attached to a frame of the conveyor, wherein the hopper weldment surrounds a charge cud of the conveyor, a flexible frame configured to enable an opening of the flexible hopper to expand or contract, and/or a skirt attached to the flexible frame and configured to form an enclosure between the flexible frame and the hopper weldment.

Disclosed is a blast furnace apparatus includes: a rotating chute; a profile measurement device configured to measure surface profiles of a burden charged into the furnace; and a tilt angle controller configured to control a tilt angle of the chute, in which the device includes a radio wave distance meter installed on the furnace top and configured to measure the distance to the surface of the burden, derives the profiles on a basis of distance data for the entire furnace obtained by scanning a detection wave of the distance meter in the furnace in a circumferential direction, and includes at least one of arithmetic units configured to command during rotation, on a basis of the surface profiles obtained, the controller to change the tilt angle of the chute, or a controller to change a rotational speed of the chute or a feed speed of the burden fed to the chute.

A gravity-feed dispenser is connected to a hopper configured to hold a bulk material for dispense. The gravity-feed dispenser includes a spout and a valve separating the hopper from the spout. An actuator assembly is connected to the valve and includes a detectable element. The actuator assembly is operable to move the valve between open and closed conditions to selectively permit bulk material to pass from the hopper out of the spout. A fixture is configured to engage and support the gravity feed dispenser. A sensor is connected to the fixture and is positioned relative to the actuator assembly. The sensor operates to detect the detectable element of the actuator assembly and produce a signal indicative of the open condition or the closed condition.

A valve for controlling the flow of a solid material from an opening includes a gate having a first face adjacent the opening, a second face opposite the first, and an orifice. A support is disposed adjacent the second face of the gate and is configured so that the gate can move relative to the support from a first position permitting the material to flow from the opening through the orifice and a second position preventing the material from flowing through the opening. The support is movable in a direction substantially orthogonal to the first direction so that the distance from the first face to the opening can be varied.

An additive manufacturing system can include a powder dispenser; a gate adjacent to the powder dispenser; a recoater blade system; and a control operable to move the gate with respect to the powder dispenser to selectively dispense powder from the powder dispenser.

1.It is disclosed an autonomous monitoring system based on a magnetic field variation: (a) that allows (i) predicting wear, failures and cracks in mining equipment; (ii) prevent and detect, in real time, uncrushable material such as metal and/or material from old mining or past operations and/or parts or pieces of mining equipment; (b) to be used/installed in mining and/or loading equipment, such as, but not limited to, cables shovel, hydraulic shovel, a loader or other type of loader; (c) that allows detecting strange metal bodies, and also, knowing the level of wear and/or detecting a failure or fracture in the parts of these equipment almost immediately, particularly, but not limited to, the teeth or part of them, preventing unscheduled stops and accidents of the personnel, and improving effectiveness and efficiency in the planning of predictive and preventative maintenance operations;

2.an installation method of the system.
3.an operating method of the system.
4.tooth, ground engaging tool or part of a mining and/or loading equipment, which comprises one or more monitoring devices.

A flume for supplying vegetable pieces in a supply of liquid, the flume extending between a flume inlet and a flume outlet, the flume comprising: a gulley section having an upstream inlet end at the flume inlet and a downstream outlet end, the gulley section having opposed sidewalls and a gulley floor therebetween, and a spreader section having opposed first and second lateral walls and a spreader floor therebetween, the spreader section having an upstream end connected to the downstream outlet end of the gulley section, the spreader section progressively increasing in width between the opposed first and second lateral walls in a downstream direction from the upstream end to a downstream end of the spreader section, wherein the opposed first and second lateral walls are each outwardly inclined away from a longitudinal axis of the spreader section by a respective angle ?? for the first lateral wall and ?? for the second lateral wall, in respective opposite directions, which extends from the upstream end of the spreader section to the downstream end of the spreader section, wherein the gulley section has a width of the gulley floor at the downstream outlet end of W1, the length of the spreader section between the upstream and downstream ends of the spreader section is N, and the dimensionless ratio N/W1 is within the range of from 2 to 15, and wherein the sum of ?? and ?? is from 10 to 25?.

A hopper and a mineral material processing plant. The hopper includes hinged side walls configured to be pivoted into a first position and a second position and a connection wall attached between the hinged side walls. The connection wall includes a flexible member and is configured to fold together in response to the hinged side walls being pivoted from the first position to the second position.
