The cement grinding unit is the last stage of the whole cement production line. It mixes limestone, clay and other materials into cement clinkers for grinding and finally produces finished cement products. The new type of cement grinder machines manufactured by Machinery with the pre-grinding technology will crush the grinding material into smaller particle sizes. At the same time the cracks which are beneficial to mixing with cement clinker, improving production efficiency and reducing energy consumption are inside the particles of material.
The main equipment of cement grinding unit consists of a crusher, powder mill, bucket elevator, dust wiper, belt conveyor, screening equipment, packing equipment, etc.
High grinding efficiency; On the structure of cement grinding machine, we adopt advanced and special warehouse separating device for selecting powder inside. It increases the activated device in fine grinding storehouse, in the end it has dedicated discharge grate plate. The cement grinder machines minimize the grinding media size, greatly improve the grinding efficiency and achieve the goal of high output, low energy consumption.
Energy-saving and environmental protection; The selected equipment of the cement grinding unit has a simple structure, strong controllability and easy operation and maintenance. The pulse bag filter is used for dust collection of cement grinding unit, and the emission concentration is lower than the national emission standard, so as to effectively protect the environment of the whole production site.
Good quality production and high yield; The technology overcomes the disadvantages of the traditional equipment that is the temperature is not easy to control, the quality of cement clinker grinding machine is unstable, the energy consumption of it is large, its environmental pollution is serious, and the thermal efficiency of cement grinding machine is low
High processing capacity; Under the same particle size and the same power condition compared with other processes, the output of cement grinding unit can be increased by 30% at most, and the energy consumption in production will be reduced by about 15%.
The operation of the grinding unit belongs to the third stage of the cement production line and that is one of the most important stages of cement making plant. The cement clinker made with limestone and clay is sent into raw material storage of the cement plant, at the same time, gypsum and adding material are sent to storage respectively after crushing and grinding. Then these raw materials are mixed by batching scale of cement making plant according to the reasonable mixing ratio and transported into the powder mill of cement grinding unit for grinding, mixing well to form cement, finally after dust removal, packaging and other procedures to get cement products.
