摘要：
A process for producing resin-coated sand particles for use in shell moles wherein a phenolformaldehyde resin in an initial stage of condensation is sprayed into a hot zone to form droplets which gravitationally descend to a cold zone and solidify. The particles are mixed with sand, heated to a temperature above the melting point of the resin and coat the sand.
