Remote controlled refractory gunning apparatus

A vertical refractory gunning apparatus comprising:

• (i) a rotatable vertical gunning conduit having an upper and lower extremity, said gunning conduit terminating at the lower extremity in a nozzle;
• (ii) a housing, said gunning conduit being located within said housing;
• (iii) a water supply conduit entering and supplying water to the apparatus within said housing;
• (iv) a material supply conduit entering and supplying refractory material to the apparatus within said housing;
• (v) a mixer-swivel head located within said housing comprising,
• (a) means for connecting said material supply conduit to said mixer-swivel head;
• (b) means for connecting said water supply conduit to said mixer-swivel head;
• (c) means for mixing the refractory material with the water in said mixer-swivel head;
• (d) a bearing assembly in said mixer-swivel head, said bearing assembly comprising an inner casing surrounding said means for mixing the refractory material with the water, bearing means surrounding said inner casing and an outer casing surrounding said bearing means, whereby rotation of said gunning conduit is facilitated by said bearing assembly;
• (vi) a control unit disposed in the water supply conduit, said control unit controlling amount of water supplied to the mixer-swivel head;
• and
• (vii) an abrasion resistant liner lining the bearing assembly and the means for mixing the refractory material with the water, said liner and said means for mixing the refractory material with the water being removable through the top of the housing as a unit separable from said bearing assembly.
