Apparatus and method for removing foreign materials from a cement metering wheel |
摘要 |
Access to a cement metering wheel for purposes of cleaning, without spilling cement from a storage tank disposed above the metering wheel, is provided by pivoting the wheel assembly downward and away from the bottom of the tank. A gate slot in the bottom of the tank is adapted to receive one or more blocking plates, prior to pivoting the wheel assembly, so as to block the gravity-feed outflow opening from the tank. Selectively removable slot covers are provided to prevent cement spillage from the open side of the slot during normal cement metering operation.
