A ceramic products manufacturing apparatus for controlled depositing of solid loose material on surfaces to be treated, comprising: • at least a dispensing device for controlled dispensing of a solid loose material, wherein the dispensing device comprises: - a container hopper of the material provided with a plurality of discharge mouths, - a plurality of distribution elements, each of which is located at a distance below a relative discharge mouth such that material exiting each discharge mouth can accumulate thereon, wherein each distribution element is inclined with respect to a horizontal plane, such as to define a sliding direction of the material towards at least a falling edge of the distribution element, - a plurality of vibration means (5, 50), each of which is associated to a respective distribution element for vibrating said distribution element, such that the accumulated material slides on the distribution element up until the material falls from the falling edge thereof, and - electronic control means for activating each vibration means (5, 50) independently of one other; wherein the apparatus further comprises: • movement means for realising a relative movement in at least a reciprocal sliding direction between the dispensing device and an underlying surface to be treated on which the material is to be deposited; characterized in that the movement means comprise a sliding carriage which bears the dispensing device and is destined to slide with respect to a fixed support plane which bears the surfaces to be treated and in that each of the distribution elements is inclined of an inclination comprised between 0° and 10° with respect to the horizontal plane. • at least a dispensing device for controlled dispensing of a solid loose material, wherein the dispensing device comprises: - a container hopper of the material provided with a plurality of discharge mouths, - a plurality of distribution elements, each of which is located at a distance below a relative discharge mouth such that material exiting each discharge mouth can accumulate thereon, wherein each distribution element is inclined with respect to a horizontal plane, such as to define a sliding direction of the material towards at least a falling edge of the distribution element, - a plurality of vibration means (5, 50), each of which is associated to a respective distribution element for vibrating said distribution element, such that the accumulated material slides on the distribution element up until the material falls from the falling edge thereof, and - electronic control means for activating each vibration means (5, 50) independently of one other; wherein the apparatus further comprises: - a container hopper of the material provided with a plurality of discharge mouths, - a plurality of distribution elements, each of which is located at a distance below a relative discharge mouth such that material exiting each discharge mouth can accumulate thereon, wherein each distribution element is inclined with respect to a horizontal plane, such as to define a sliding direction of the material towards at least a falling edge of the distribution element, - a plurality of vibration means (5, 50), each of which is associated to a respective distribution element for vibrating said distribution element, such that the accumulated material slides on the distribution element up until the material falls from the falling edge thereof, and - electronic control means for activating each vibration means (5, 50) independently of one other; wherein the apparatus further comprises: • movement means for realising a relative movement in at least a reciprocal sliding direction between the dispensing device and an underlying surface to be treated on which the material is to be deposited; characterized in that the movement means comprise a sliding carriage which bears the dispensing device and is destined to slide with respect to a fixed support plane which bears the surfaces to be treated and in that each of the distribution elements is inclined of an inclination comprised between 0° and 10° with respect to the horizontal plane.
