The utility model discloses particle detection equipment which comprises an adjustment base, a clamping roller group and a pressure sensor, wherein the clamping roller group comprises a first clamping roller and a second clamping roller which are parallel to each other; two ends of the first clamping roller are arranged on the adjustment base; the second clamping roller is arranged on the adjustment base by virtue of the pressure sensor. According to the particle detection equipment, when paper carrying impurity particles runs between the first clamping roller and the second clamping roller, the impurity particles push the second clamping roller to trigger the pressure sensor at the tail end of the second clamping roller, so that the impurity particles on the paper can be quickly detected without manual detection; therefore, the working efficiency is improved, and the production cost is lowered; furthermore, the method for brushing off the impurity particles by a hairbrush is not adopted, the problems of dust generation, hair releasing, scratching injury to the surface of the paper and the like can be solved.
