Henan Hongxing machine is the most powerful rotary kiln equipment manufacturers in Henan, it can provide high quality building materials metallurgical and chemical cement rotary kiln series equipment as well as supporting mineral processing equipment, drying equipment and so on. This article describes the reasons for controlling shaft kiln clinker yield as well as the cause of the low yield.
Among shaft kiln clinker, it often appear some of the raw burning material, the raw material and pulverized material, these materials are the main reason for low quality of clinker. Therefore, it must be strictly controlled. Control of their amount is actually control the yield of the rotary kiln clinker, that is, to control the quality of clinker shaft kiln.
Shaft kiln raw burning materials generally refer to the yellow ball, gluten meal, and yellow heart material and raw materials generated in low-temperature state. The burning materials are mostly firing at about 1200 with features of liter light weight, low intensity and stable adverse. Some burning materials look like clinker, appear dark green, but the interior do not be burnt through yellow, that is the yellow heart material.
The feedstock is caused by insufficient ventilation, internal hypoxia and serious reduction atmosphere in the middle of the kiln equipment; it is still low temperature firing material. Their petrographic structure is not normal, with low quality.
Generation of pulverized material is mainly due to the improper ingredients, uneven raw material ingredient, low rotary kiln calcination temperature, too high facao, poor cooling, excessive coal or uneven distribution of coal ash, causing the transformation of C2S to crystalline.
