Reflective luminescent markings on a road or sign surface are formed by applying onto the surface a base material which is liquid in an initial state for application and sets or cures to form a solid layer after application where the base material contains a fine/medium filler material of glass ground from recycled materials in a rotary mill. Coarse material from the grinder is separated out and supplied as a separate material to be applied onto the surface of the layer of base material and fine ground glass. The base material is connected or impregnated with a luminescent material such as photo luminescent 2 4 6 trichlorophenyl in a binder such as polyurea.

An apron return assembly having a pump that is adapted to convey a fluid, an apron actuator having an apron actuator cap side and an apron actuator rod side and being in fluid communication with the pump, an accumulator that is in fluid communication with the apron actuator cap side, a reservoir that is in fluid communication with the apron actuator, and a tension rod having a frame end and an apron end. In the preferred apron return assembly, the apron actuator and the tension rod are adapted to move the apron between a closed position and an open position. A method for moving the apron from the open position to the closed position.

A mill includes a generally vertical, rotatable shaft having at least one set of cutter blades driven thereby and a fan assembly mounted on the shaft below the cutter blades in position to receive output therefrom. The fan assembly includes a fan disc secured to the shaft and rotatable therewith. A plurality of fan blades is secured to the fan disc in a generally radial orientation. A terminal portion of the mill includes a gradually, radially expanding outer wall configured in a volute form. The expanded outer wall decreases wear and increases efficiency of discharge and airflow through the mill.

A crushing device includes a horizontal shaft impact crusher having an impeller rotating around a horizontal shaft and at least one curtain against which material may be crushed. The crushing device further includes a first feeding device for feeding a first type of material to be crushed to a crushing chamber of the horizontal shaft impact crusher. A second feeding device feeds a second type of material, having a smaller average particle size than the first type of material, to the crushing chamber simultaneously with the first feeding device feeding the first type of material to the crushing chamber. A mixing arrangement for at least partially mixes the first and the second types of materials with each other before bringing them into contact with the impeller.

An apparatus including a rotor position detection unit with a sensor configured to detect an angular position of a rotor of a horizontal shaft impact crusher, the rotor having attached thereon a group of hammers. A motor control system is configured to change the rotation speed of the rotor and an automation and control system is configured to control the motor control system in response to the detected angular position of the rotor.
