A continuous concentrate feeding equipment of the present invention, which can supply the concentrate to a smelting furnace continuously when the concentrate is received, includes a pressure-adjusting tank that temporarily accumulates granular concentrate; a lift tank that receives the concentrate from the pressure-adjusting tank and discharges the concentrate to a smelting furnace; an air passage for introducing compressed air into the pressure-adjusting tank and the lift tank, respectively; and control means for controlling the compressed air, and the concentrate is continuously supplied from the lift tank to the smelting furnace even when the lift tank receives the concentrate from the pressure-adjusting tank by the control means.

A powder-dispensing device in the form of a dense-phase powder pump or of a powder injector is provided to deliver coating powder from a powder reservoir to a powder-spraying device. To make the spray coating operation easier for the customer and to be able to make it more cost-effective, without having to compromise on good coating quality and good coating efficiency, a control device is integrated in the powder-dispensing device or is connected, in particular directly, to the powder-dispensing device and is designed to establish at least one parameter that is characteristic of a spray coating procedure carried out with the powder-coating device.

Provided is a polycarbonate resin powder, including a polycarbonate-polyorganosiloxane copolymer, in which an amount of particles each having a particle diameter of 300 μm or less in an entirety of the powder is 60 mass % or less.

A conveying system for conveying a conveyable material from a hopper where the system includes a fluid port located below the hopper outlet and in a vertical flow path into hopper outlet that can be momentarily opened for an on the go release of a charge of compressed air directly upward into the hopper outlet and into the underside of the bridge in the hopper to either disintegrate or unlock the bridged particles from each other thereby causing the bridged material to fall into the hopper outlet and into the conveying system where the material can be transported to a remote location or to remove any material that may be adhering to the wall during an emptying phase.
