摘要： In a toner production process having at least a kneading step, a pulverization step and the step of simultaneously carrying out a surface modification step and a classification step to obtain toner particles, the surface modification and the classification are simultaneously carried out using a batch-wise surface modifying apparatus having at least a cylindrical main-body casing, a classifying rotor, a surface modifying means having a dispersing rotor and a liner. The positional relationship between the dispersing rotor and the liner is set in an appropriate specific state so that toner particles having a sharp particle size distribution with less fine powder and having a high sphericity can be obtained in a good efficiency.

摘要： In a method for separating heavy particles from a particulate material containing such heavy particles, use is made of a device having a Coanda sifter, which is adapted to receive a flow of the particulate material and which has a downwardly-facing, convexly single-curved surface (9), and a zigzag sifter (13) arranged after the Coanda sifter and having a plurality of zig-zag-shaped vertical walls (14) which are perpendicular to the axis of curvature of the single-curved surface (9) and define between them channels (15) extending upwards in zig-zag fashion. The particulate material is transported to the Coanda sifter and is conducted over its convexly single-curved surface (9) to have imparted to it a direction of motion (P1, P2) which is dependent on the weight of the particles and in which the particles are guided into the zigzag sifter (13). The particles are guided into the channels (15) of the zigzag sifter (13) in the lower portions thereof and from the side parallel to the channel walls (14). The particles are transported up through the channels (15) with the aid of a flow of transport air which is so adjusted that the heavy particles are separated in the zigzag sifter. (13).

摘要： A particle classifier has a uniform, laminar, classifying air stream and a duct to introduce particulate material generally perpendicular to the air stream. The particulate material is entrained in a secondary air stream that is diverted as it enters the classifying air stream by a curved surface. The curved surface produces and diverts the air stream by the Coanda effect to minimize disturbance to the classifying air and segregate the particles from the secondary air.

摘要： A gas stream classifier includes: a gas stream classifying means for classifying feed powder into at least a coarse powder fraction and a fine powder fraction by an inertia force acting on particles and a centrifugal force acting on a curved gas stream due to Coanda effect in a classifying chamber, and a feed supply pipe opening into the classifying chamber for supplying the feed powder into the classifying chamber. The efficiency of the classifier is improved by providing the feed supply pipe with a mixing zone for mixing an upper stream and a lower stream of the feed powder and an accompanying gas stream, respectively flowing through within the feed supply pipe. The classifier is particularly suitably used for producing a toner for developing electrostatic images having a sharp particle size distribution from toner particles having a weight-average particle size of at most 10 .mu.m, especially at most 8 .mu.m.

摘要： A toner for producing electrostatic latent images is produced by classifying a pulverized feed material into a coarse powder and a fine powder in a first classifying means, pulverizing and recycling the coarse powder to the first classifying means, introducing the fine powder into a multi-division classifying chamber divided into at least three sections where the fine powder is classified into at least a coarse powder fraction, a medium powder fraction and a fine powder fraction. The medium powder fraction is recovered to provide a toner. The coarse powder fraction is recycled to the first classifying means.
