Field type material fine crushing and high-quality and high-efficiency uniform mixing equipment and method

Abstract

The invention provides field type material fine crushing and high-quality and high-efficiency uniform mixing equipment and method. The equipment comprises a grinding and mixing chamber and a grinding machine, the grinding and mixing chamber is defined by cylindrical enclosing walls, a feeding window is arranged on one side of the grinding and mixing chamber, a vehicle access door is arranged on a second side of the grinding and mixing chamber, and a discharging opening is formed in a third side of the grinding and mixing chamber; and the rolling machine can be driven in from the vehicle access door and performs annular rolling operation in the rolling and mixing chamber. The tail part of the grinding machine is connected with a plough share through a connecting rod, so that materials can be turned over while rolling and mixing. The grinding and mixing equipment is simple in structure and low in construction cost and operation and maintenance cost; the crushing and uniform mixing effects are equivalent to those of a common wheel rolling stirrer, but the single-batch treatment capacity is large due to field type rolling and mixing; and the grinding machine can realize material rolling and material turning at the same time, and is flexible to operate and low in failure rate.

Description

technical field [0001] The invention belongs to the technical field of industrial mixing, and relates to a site-type material finely crushing and high-quality and efficient mixing equipment and method. Background technique [0002] In iron and steel smelting enterprises, the wheel mill mixer is widely used in the field of pretreatment of cold-pressed pellet powder. When the binder ratio is not high, the strength of the briquette is not low, which can significantly save the binder and reduce the cost of the briquette. However, the disadvantage of the wheel mill mixer is that the discharge is slow and the efficiency is low. Even if the large wheel mill and the left and right double mixers are arranged in parallel, it is difficult to meet the demand for feeding large quantities of briquetting production lines. The consumption is greater than that of general twin-shaft spiral stirring. Therefore, the wheel mill mixing method is generally used when the demand for powder briquet...

This also limits the application of wheel mill mixer

[0003] In addition, for low-strength blocks such as stainless steel, carbon steel pickling sludge, and wet dust removal mud, they must be dried and pulverized before being used for sintering or briquetting. However, the natural drying process is long, and the cost of machine drying is relatively high. It is not only uneconomical to process these low-strength blocks in special fine crushing equipment, but also too fine, which does not meet the process requirements of sintering and cold agglomeration
