The invention relates to the field of lime production, in particular to a high-yield and energy-saving mixing type lime kiln. The high-yield and energy-saving mixing type lime kiln comprises a kiln body, a fire grate is arranged in the kiln body, a distributing mechanism is arranged above the fire grate, a dividing plate is further arranged between the distributing mechanism and the fire grate andobliquely arranged, a plurality of through holes used for passing of raw materials are formed in the dividing plate, the through holes are gradually enlarged in the oblique direction of the dividingplate, thus the raw materials guided into the kiln body by the distributing mechanism are screened by the dividing plate and then fall into the fire grate for calcination treatment, the raw materialsfalling onto the fire grate are treated distinctively according to the different sizes, large-size fuel and large-size limestone make contact, small-size fuel and small-size limestone make contact, the fuel and the limestone which make contact are adaptive in size, the calcination process is carried out smoothly and advantageously, the fuel consumption is decreased, waste of resources is avoided,and the production efficiency is improved.
