A plansifter works by using an eccentric weight at its base to rotate and swing the sifter stacks, which generates the sifting function. The product to be sifted enters through one or more inlets and passes through multiple layers of wire mesh sifters with different grid sizes. The horizontal circular movement of the plansifter, combined with its adjustable slope, gently treats the product as it passes over the screen. Coarse components pass over the screen, while finer components fall through the mesh. The eccentric movement causes the products to be sifted on the sieves in a circular run, which shifts the individual particles according to their specific weight. Heavier particles, such as flour, middlings, and semoina, sink downwards, while lighter particles, such as break stock with some bran and endosperm, float on top. The functions of a plansifter include: Pre-cleaning and cleaning raw grains and seeds, Grading by size, Removing large and small impurities, and Dusting with aspirator system Working principle: The sieve body and the center of gravity eccentric system are used for rotary motion, and the generated inertial force drives the powder and granular materials to produce a balanced flow in the plane, so that the materials are automatically classified. Purpose of use: It is to classify the material after grinding, so that materials of different particle levels are sent to the machines behind for further grinding and crushing, and the flour that has reached the particle size requirements of the finished product is collected or sent separately to other machinery and equipment for final processing or directly packaged. If the materials in the grinding products cannot be put forward in time, the subsequent equipment load will increase, the output will be reduced, the power consumption will increase, and the grinding efficiency will decrease; at the same time, if the various types of products in the grinding products are not classified, the subsequent System flow distribution is unbalanced. System composition, Plansifter is mainly composed of a feeding device, a pressing device, a top grid, a screen box, a frame, a transmission mechanism, a beam, a screen door and a hanging device, etc.The screen grids are stacked in each bin of the screen box according to the requirements of the screen. The compression device is simultaneously compressed in the vertical and horizontal directions, and is hung on the suspension beam of the powder room beam through the suspension device. Screen silk The screens used in flour mills are roughly divided into the following types according to their materials: Silk screen: from multiple strands of natural silk twisted into silk, and then woven. They are characterized by good elasticity, not easy to slack, and the hole size is not easy to deform. It has good moisture absorption and release properties, and is not easy to generate static electricity. But it is not abrasion resistant and easy to fluff. Nylon screen: woven by polyamide monofilament fiber. Wear resistance, long service life, high strength, and good comprehensive use effect. The polyester screen is woven from polyester monofilament. It has high strength and is not easy to deform, but compared with nylon mesh, its abrasion resistance and antistatic effect are slightly worse. "W" Coarse Wire Screen. "GG" refers to the grading screen, the weaving method is full twisted weaving. "XX" refers to the fine material powder screen, mainly used for powder screen, semi-twisted method.
