High-pressure roller mill for metal ore

Abstract

The invention belongs to equipment for pulverizing a metal ore rock material, which consists of a stander, high-pressure rollers, a universal transmission shaft, a retarder, a feeding adjustment device, a hydraulic control system, an electric control system and other main parts. Two sets of high-pressure roller devices are horizontally arranged on the stander in parallel; a driving mode of the equipment comprises that: a motor is connected with the high-pressure rollers through the retarder and the universal transmission shaft; each set of the high-pressure roller is provided with each independent drive device, wherein one set of the high-pressure roller is fixed; the other set of the high-pressure roller can slide in the horizontal direction; one side of a movable roller is provided with a pressure application hydro-cylinder; and two sides of the end face of the high-pressure roller are provided with self-adaptive floating side baffles. The pulverization equipment is high-efficiency, energy-saving and consumption-reducing and has remarkable economic benefit.

Description

technical field [0001] The invention belongs to equipment for crushing ore and rock materials, which can be widely used in the crushing of brittle ore rocks in metal mines, chemical industry, building materials and other industries, and has the characteristics of energy saving and consumption reduction. Background technique [0002] Because most of the iron ore in our country have complex ore types, many lean ores, many compound ores, and the embedded particle size is fine, more than 90% of the mined ores need beneficiation treatment. Therefore, the amount of ore to be ground is large and the energy consumption is high, and most of the power of the concentrator is consumed in grinding. At present, the equipment used for grinding in my country is mainly ball mills. Although a lot of work has been done on the enlargement of ball mills, the improvement of media and liner materials, the grinding efficiency and steel ball consumption have not changed much. The highest efficiency ...

Therefore, the amount of ore grinding is large and energy consumption is high, and most of the power of the dressing plant is consumed in grinding

At present, the equipment used for grinding in my country is mainly ball mills. Although a lot of work has been done on the enlargement of ball mills, the improvement of media and liner materials, the grinding efficiency and steel ball consumption have not changed much. The highest efficiency is still no more than 10%

However, the existing roller mills have the disadvantages of complex transmission mode, inconvenient maintenance, and difficult replacement of the roller surface after wear.
