A device and a system monitor wear of wearable components mounted in a mining equipment. An elongated bolt maintains a wearable component in place on a face of the equipment. A threaded section of the bolt terminates at a proximal end protruding externally through a hole of the equipment. A shank of the bolt terminates at a distal end opposite from the proximal end. The shank extends along a thickness of the wearable component and wears as the wearable component wears when the equipment is in operation. A transducer coupled to the proximal end of the bolt generates a sound wave within the bolt, detects an echo of the sound wave reflected by the distal end of the bolt, and reports to a controller a time delay between the sound wave and the echo. The controller evaluates a wear of the wearable component based on the time delay.

A lifting apparatus (100) for hoisting a spider (200) of a gyratory crusher has a spreader (110) spanning between two leg members (120) each having an offset arm (121a), clearing arm (121b), cradle arm (121c), and securing arm (121d). The offset arm (121a) forms a second offset distance (131) with respect to an offset axis (C). The arms (121a-121d) form an opening (123) for receiving the spider (200). The leg members (120) oppose each other such that the clearing arms (121b) of the leg members (120) are provided on opposite sides of a plane defined by the horizontal axis (D) and vertical axis (A). The lifting apparatus (100) may be lowered over the spider (200), and rotated approximately 90 degrees in a direction (B) of rotation about the vertical axis (A) to cradle and support the spider (200) from below the spider (200).

The invention relates to a method for controlling and/or regulating the feed of material to be processed, in particular rock material, to a crushing and/or screening plant of a material processing device, wherein a conveyor device is used to guide the material to be processed to the crushing and/or screening plant, wherein a characteristic of the material to be processed is determined, and/or wherein a volume flow of the material to be processed is determined, and wherein a conveying speed of the conveyor device is controlled and/or regulated taking into account the characteristic and/or the volume flow of the material to be processed. The invention also relates to a material processing device designed to perform such a method.

The invention relates to a method for determining the layer height of a feed material, which is supplied to a crushing and/or screening plant of a material processing device, wherein a conveyor device is used to convey the feed material in a conveying direction, wherein a sensor array comprising a plurality of sensors is used to determine the layer height of the feed material. A reliable method that can be performed with little effort and without impairing the operation of the material processing device is achieved by the longitudinal axes of the detection volumes of the sensors extending at least partially in and/or counter to the conveying direction.

An advanced manufacturing plant and process to efficiently deconstruct and recycle post-consumer carpet primarily in an aqueous environment. The water-based technology substantially eliminates airborne particulate emissions into the workplace and the environment. It also significantly increases the quality and quantity of the resources recovered from the carpet. In addition to recycling residential carpet, it also reclaims and recycles material from commercial broadloom carpet.

A device for generating milling measurement data at an output includes a support structure. A measurement station is supported by the support structure for measuring an attribute of milled material collected thereon and outputting a measurement of the attribute to the output. A mill is supported by the support structure above the measurement station for, while engaged, performing a continuous milling action on a feed material, and continuously or regularly depositing milled material onto the measurement station wherein the measurement station can measure the milled material without interrupting the milling action

While a part of an article is crushed to be collected, a crushed pieces collector reduces the number of uncollected crushed pieces and the crushed pieces scattered over the floor to improve efficiency of collection and to prevent a foreign matter from being mixed into the collected crushed pieces. The crushed pieces collector is configured to collect the crushed pieces while a crush object is crushed to be removed from a fixed object to which the crush object is fixed. The crushed pieces collector includes: a receiving portion placed below the crush object to receive the crushed pieces; and a contact portion provided contiguously with the receiving portion and in contact with the fixed object. The contact portion includes an elastic body elastically deformable along an outer surface of the fixed object.
