I. Raw materials for production
1. Limestone, dolomite and chalk
The particle size of raw material is required to be 10-40mm, the part exceeding the upper limit of 40mm and the lower limit of 10mm shall not exceed 5%, and the maximum particle size is ≤ 50mm.
2. Fuel
The fuel can be producer gas, natural gas, coal bed gas and pulverized coal, or electric heating.
II. Production process
(1) Raw material storage and transportation
Limestone with particle size of 10-50 mm is transported to the plant area and stacked in the stockyard. Loaders are used for stockyard operation. The materials with qualified particle size are loaded into the receiving trough set up in the material yard by the loader. Under the receiving trough, the material is quantitatively fed by the feeder. The stone is sent to the large angle conveyor and then to the screening building. The limestone with qualified particle size after screening is weighed and then sent to the top bin of the preheater by the large angle conveyor. The sifted powder is sent to the storage yard by conveyor and transported out by forklift regularly.
(2) Limestone calcination
Limestone calcination is composed of vertical preheater + rotary kiln + vertical cooler, with the output of 100 ~ 800t / D. the materials are introduced into the preheater body through the feeding chute from the top bin of the preheater. At the same time, the high-temperature flue gas from the rotary kiln preheat the materials to above 1000 ºC, so that the limestone is partially decomposed, and then pushed into the tail of the rotary kiln in turn by the hydraulic push rod, and then discharged after high-temperature calcination in the rotary kiln The material is cooled to the ambient temperature below + 60 ºC and discharged from the cooler. The air blown through the cooler enters the rotary kiln as secondary air to participate in combustion.
