Abstract

The invention provides an efficient drying and grading machine for a processed object and a drying and grading method. The drying and grading machine comprises a rotary cylinder capable of freely rotating around the axis thereof. One end of the rotary cylinder is equipped with a feeding port for an object to be processed and a carrier gas and the other end of the rotary cylinder is equipped with a discharge port for the object to be processed and the carrier gas; a heating unit for heating and drying an object to be processed in the rotary cylinder during the delivery process of the object from the feeding port to the discharge port; a grading cover arranged to cover the other end side of the rotary cylinder. The lower part of the grading cover is equipped with a fixed discharge outlet for discharging the processed object and the upper part of the grading cover is equipped with a fixed gas outlet for discharging the gas carrier; and a dispersed gas blowing unit arranged inside the grading cover wherein the processed object is sent to the fixed discharge outlet.

Description

technical field

[0001] The invention relates to a drying classifier and a drying classifying method for dry classifying objects to be processed. Especially when coal is used as the object to be processed, the effect of the present invention can be remarkably exhibited. Background technique

[0002] In the manufacture of coke, due to the shortage of high-quality caking carbon (strong caking carbon and weak caking carbon) and the high price, coal with low caking property is widely used for manufacturing. Coal with low caking property can be dried and used, but when the moisture content becomes 6.5% or less, coal particles less than about 100um will generate dust (dusting), which will lead to problems such as deterioration of the working environment. Furthermore, when coal fine particles of about 300 um or less are supplied to the coke oven, there is a problem that carbon adheres to the inside of the coke oven. Therefore, in order to solve these problems, fine particles are c...
