Abstract: A mobile gunnite material mixer comprising a vehicle having a first load carrying portion for housing a supply of sand, a second load carrying portion separate from the first load carrying portion for housing a supply of cement, a mixing apparatus spaced outboard of the second load carrying portion, conveying belt disposed beneath the first and second load carrying portions and extending to the mixing apparatus, the belt being in constant linear motion during use of the apparatus whereby a quantity of sand is initially deposited on the moving belt and a quantity of cement is deposited on the moving belt over previously deposited sand, and the sand-cement mixture is discharged into the interior of the mixing apparatus wherein the sand and cement are thoroughly mixed and discharged into the usual gunnite delivery apparatus. The gunnite is mixed with water in the delivery apparatus whereupon the fluid mixture may be sprayed onto a surface in the usual manner.
