Method for rolling and grinding by high pressure roller press for fine chemical engineering and implementing system thereof

Abstract

The invention discloses a method for rolling and grinding by a high pressure roller press for fine chemical engineering, which comprises the following steps of: feeding a material to be ground quantitatively into the roller press through a conveyor for medium grinding; discharging a tablet material cake under the high pressure action of the roller press; and then performing fine grinding on the material cake. The roller press uses the high specific pressure of 6.0 to 10.0Mpa; a roller surface of the roller press is a smooth surface; and the requirement on product granularity is met by rolling at one time, energy is saved and consumption is reduced. In a grinding process of the material, a Raymond mill system or a ball milling system can be replaced, and the method can be used for improving a new construction item or an old system; and the method and the system have the advantages of small investment, short downtime, low consumption of water, electricity and gas, short time of equipment maintenance and the like.

Description

technical field [0001] The present invention relates to a high-pressure roller press used for fine chemical industry and other industries that require high-pressure grinding for materials, such as the high-pressure roller press used for fine chemical industry for intermediate crushing of titanium dioxide kiln products The process of roller pressing and grinding by machine, and the supporting system equipment for implementing this process. Background technique [0002] In the fine chemical industry, there are many materials that need to be ground. During the grinding process, their physical and chemical properties must not be damaged, and impurities must not be mixed. For example, the production of titanium dioxide is an extremely fine chemical processing process, which requires high product quality, far exceeding the requirements of pure chemicals. It not only requires high content of effective chemical components and low content of harmful impurities, but also must have goo...

Problems solved by technology

The Raymond mill in the Raymond mill crushing process determines its low production capacity and high energy consumption (water, electricity, gas) due to its grinding mechanism. The dust pollution is serious, the noise is large, the quality is poor, and the waste is large.

In recent years, improvements to Raymond mills have been made at home and abroad, which can slightly increase output and reduce energy consumption, but cannot significantly save energy and reduce consumption
