Efficient grinding equipment for hot-melt reflective coating

The invention discloses efficient grinding equipment for a hot-melt reflective coating. The efficient grinding equipment comprises a shell, supporting legs and a filter sieve; the supporting legs arearranged at the four corners of the bottom of the shell; the filter sieve is arranged at the upper part of the interior of the shell; and one side of the bottom of the filter sieve is fixed to a supporting plate through a spring column. According to the efficient grinding equipment, the filter sieve is arranged in the equipment shell, a vibrator vibrates the filter sieve so as to separate large-particle raw materials, coating powder meeting the conditions is collected through a first collecting hopper to be conveyed to the outside, then large particles are independently ground and crushed through a grinding roller, by means of the design, the grinding roller only needs to grind the large particles, so that the grinding efficiency and effect are improved, an air draft device is arranged atthe bottom of a discharging pipe, so that the coating powder can be conveniently collected by the first collecting hopper and a second collecting hopper through the air draft device, and the phenomenon that the working environment is influenced due to the fact that dust in the equipment flies upward can be avoided.
