Differential three-roller roller press

Abstract

The invention discloses a differential three-roller roller press. The differential three-roller roller press comprises a rack, a driving device, a movable roller and a feeding device, and is characterized in that an upper pressing roller and a lower pressing roller are installed at the upper position and the lower position of the movable roller respectively, the movable roller is a driving roller, the driving device drives the movable roller to rotate, the upper pressing roller and the lower pressing roller are driven rollers, and the upper pressing roller and the lower pressing roller are driven by the movable roller and materials to extrude and grind powder. According to the differential three-roller roller press, the driving device drives the movable roller to realize single transmission, so that the power consumption is reduced; differential rolling grinding is adopted, and through the extrusion of the extrusion rollers on the materials and the shearing action among the materials, the one-time yield of grinding can be improved, and the rollers can be controlled not to be excessively abraded; the materials are extruded and sheared through the differential speed between the two rollers, and are rolled twice, so that the one-time yield is improved; and a hydraulic device and the movable roller are further arranged in a position-adjustable mounting mode, and a hydraulic cylinder is controlled to advance and retreat when necessary so as to impact and extrude materials by the movable roller.

Description

technical field [0001] The invention relates to the field of grinding equipment, in particular to a differential speed three-roller rolling machine. Background technique [0002] Roller presses are also called squeeze mills and roller press mills. They are mainly used to grind slag, cement clinker, etc. . At present, it is very common to use traditional dynamic roller presses as grinding equipment in industries such as cement building materials, coal, steel, and thermal power generation. Due to high efficiency requirements, various industries have also begun to develop energy-saving equipment. Traditional roller presses are about 60% more energy-efficient than ball mills, and have been widely used. However, traditional roller presses are mainly affected by The extrusion force of the extrusion roller forms a material cake, which makes the yield of the traditional roller press low at one time, and requires repeated rolling and grinding, which leads to the actual power consum...

At present, it is very common to use traditional dynamic roller presses as grinding equipment in industries such as cement building materials, coal, steel, and thermal power generation. Due to high efficiency requirements, various industries have also begun to develop energy-saving equipment. Traditional roller presses are about 60% more energy-efficient than ball mills, and have been widely used. However, traditional roller presses are mainly affected by The extrusion force of the extrusion roller forms a material cake, which makes the yield of the traditional roller press low at one time, and requires repeated rolling and grinding, which leads to the actual power consumption saving of only about 30-40% of that of the ball mill; at the same time, the traditional roller press The roller press adopts double transmission to drive its two rollers, so that the two rollers run in opposite directions at the same speed, which also increases energy consumption, which is not conducive to energy saving
