济南水泥球磨机厂家，优质济南产水泥磨,回转窑生产企业

用途：原料磨广泛用于建材、冶金、电力及化工行业磨粉（烘干兼粉磨）水泥原料及其他物料。

  分类及特点：

1. 适用于中小型规模的原料粉磨系统，一般用于磨外选粉的圈流粉磨系统。
2. 风扫磨的特点是短而粗，进出料中空轴轴颈大，烘干仓和粉末仓之间的隔舱板蓖缝面积很大，磨尾无出料蓖板，故通风阻力很小，粉末仓的风速可达5m/s以上，能够进入大量的热风，因而烘干能力强。
3. 尾卸提升循环磨与风扫磨的基本区别在于入磨物料通过烘干仓的尾端用机械方法卸出，然后利用提升机送入选粉机，粗物料再返回磨机循环粉磨。
4. 中卸提升循环磨从烘干作用来说，是扫风磨和尾卸提升循环磨的结合；从粉末作用来说，实际上相当于二级圈流粉末系统。这种磨机前端设有烘干仓，具有良好的烘干效果：原料从磨头喂入，选粉机的回料分别从磨头、磨尾回入粗磨仓和细磨仓；磨中出料，经提升机提至选粉机分选；大部分回料回入细磨仓，其余回入粗磨仓。
5. Usage:

Raw material Mill is widely used for grinding(drying plus grinding) cement raw materials or other materials used in building material, metallurgical, electric power ad chemical industries.

1. Sorts and features:

(1). Common raw material mill It is the same with diminutive and medium-sized grinding cement raw material system, often use in the circularity grinding system with select powder outside the mill.

(2). Air-swept mill The feature of Air-swept mill is short and thick, large neck-doameter of enter and emerge-material shaft, big area of the partition wall’s aperture between dry storehouse and grinding storehouse, no fine-toothed comb board on the rail of the mill, so the resistance of the aeration is small, the wind speed in the grinding storehouse can reach 5m/s,in a position to a mass of high-temperature.

(3). Tail discharge and Exaltation circulate mill   Its basal emerge-material thread-drying storehouse to grinding storehouse’s tail part with mechanical method. Afterwards, delivers into select-powder machine with upgrade machine, the thick material returns into the mill for circle grinding.

(4). Middle discharging and exaltation Circulate Mill It is combined with Air-swept Mill and Tail-discharging and Exaltation Circulate Mill from dry action; from the grinding action, it is correspond a second-grade circularity grinding system. There is drying store house in the mill’s forepart; it has very good dry effect. Raw material go into the front of the mill, the returned material from select-powder machine goes ino thick-grinding and fine-grinding storehouse form the forepart and end-part. The material comes out from the middle-part, delivers into select-powder machine with upgrade machine. A majority of material goes into the fine-grinding storehouse and the rest goes into the thick-grinding storehouse.
