Small Cement Production Line Designs

1, Crushing And Pre-Homogenization

Crushing. During the Small Cement Production Line, most of the cement raw material to be crushing, such as limestone, clay, iron ore and coal. Limestone is the largest amount of cement production of cement raw material, the larger the particle size after mining, high hardness, thus crushing the material crushing limestone cement plant occupies important position. Cement raw material pre-homogenization. Pre-homogenization technique is to keep the cement raw materials, take the process of applying scientific stacker reclaimer technology to achieve preliminary homogenization of cement raw materials, cement and raw material storage yard along with all of the features.

2, Raw Material Preparation

During the Small Cement Production Line, each producing one ton of Portland cement grinding at least 3 tons of materials (including cement raw materials, fuel, clinker, mixed materials, gypsum), according to statistics, the dry process cement production line grinding operations need to consume more power accounts for about 60% full power plant, where raw material grinding accounted for more than 30 percent, accounting for about 3% of coal mill, cement grinding about 40%. Therefore, a reasonable choice of grinding equipment and processes to optimize the process parameters, the correct operation, control operation system for ensuring product quality, reduce energy consumption is of great significance.

3, The Raw Meal

NSP During the Small Cement Production Line, stable pit entry clinker raw material component is stable firing thermal system of the premise, raw material homogenization system plays a stable raw material ingredients pit entry last a gatekeeper role.

4, Preheat Decomposition

The raw material preheating and partial decomposition done by the preheater, rotary kiln instead of some functions, to shorten the length of the kiln back, while the kiln feed gas to accumulate state heat transfer process to move to the inner suspension preheater carried out, so that raw materials can be mixed with the hot gas discharged from the kiln, increasing the contact area between the gas feed, heat transfer speed, high heat exchange efficiency, to improve the kiln system productivity, reduce heat consumption of clinker burning the purpose.
