Profile: Bharath Industrial Works is a manufacturer of plants based on pulverizer, crusher, mixer and material conveying equipments. Our products include concrete crushers, small rock crushers, portable rock crusher systems and plant on turnkey basis. Trapezium mill includes grinding mill in which air is driven into the undersurface of the grinding ring and flows upward, carrying fines to the classifying section. The classifier allows the pulverized material to pass and the oversized particles are drove back to the grinding chamber for further processing. The whole mill operates under negative pressure conditions, which can maximize the service life of major mechanical components. The diameters of each part of rollers and rings are different, the upper part is big and the lower part is small, then they formed a trapezium form. This form can reduce material sliding speed downwards and prolong the grinding time for materials.
