Effect of the height of grain layer in the feed hopper on pressure created by hammers in the grinding chamber

Hammer crushers are used for grinding grain due to the simplicity of their designs and reliability. When crusher rotor rotates in the grinding chamber, air flows are created, which, due to the forces of air aerodynamic resistance, pick up particles of the crushed raw materials. The hammer crusher with an increased separating surface, where the working chamber is formed by two end sieves and one peripheral sieve, was developed in the laboratory of SBEI HE Nizhniy Novgorod State Engineering and Economic University. Hammers shaped as longitudinally bent steel plates straight hammers and a combination of straight hammers and angled blades installed between them were used as the working parts of the hammer crusher.
