Embodiment Construction

[0014] The present invention and its advantages will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] The specific embodiment of implementing equipment of the present invention, its technological process is as figure 1 As shown, the specific equipment layout is as follows figure 2 As shown, the equipment includes a material conveyor 1, a powder separator 14, a constant weight bin 10, a roller press 11, a blower 15 and a cyclone dust collector 8, wherein: the air outlet of the blower 15 is connected to the powder separator 14 and the cyclone respectively. The air outlet of the dust collector 8 supplies air to the powder separator 14 to provide the necessary wind force. The air inlet of the powder separator 14 is also connected with a hot air supply pipeline for supplying the heat source used for drying. The wind direction is shown in the figure Indicated by the middle arrow; the discharge port of the conveyor 1 is connected to...

Abstract

A method for preparing the raw material of cement includes such steps as conveying the material into a powder classifying machine, pulverizing, classifying, baking the qualified product, storing it in warehouse, conveying the coarse particles in a constant-weight warehouse, rolling to become cakes, and returning them back to said powder classifying machine.

Description

technical field [0001] The invention relates to a preparation method and equipment for cement or raw meal grinding and powder selection. Background technique [0002] Cement raw meal preparation is an important step in cement production. The existing raw meal preparation process is limited by the entire process system and grinding equipment, and there is a problem of excessive grinding energy consumption. [0003] Specifically, in the cement raw meal process, the processing raw materials used are relatively humid, and they need to be dried before they can be processed into qualified materials and qualified finished products. In the traditional process, the drying step is generally carried out in the ball mill, and the drying is carried out while grinding. If other grinding machines are used, due to the limitation of the entire process system and equipment, effective drying cannot be carried out in the grinding machine. Therefore, the existing Most of the processes for produ...
