Introduce to Four Process of Vertical Mill
Vertical mill is a type of milling equipment widely used in cement, chemical industry, coal and electricity industries, featured by a small size, low energy consumption, little noise, simple process and compact arrangement, etc, setting crushing, drying, milling and selecting in one. Therefore, it’s the preferred equipment for grinding and milling raw materials for a modern cement plant.
Has overcome the defect of easy-vibration and easy-abrasion, the vertical mill has gradually become the principal force of processing micro slag powders. The specific surface area of the micro slag processed by this machine is 420~450m2/kg which greatly satisfies the demands of the customers. The vertical mill researched by Hongxing Machinery is integrated with drying, powder grinding, powder concentrating and elevating, adopts reasonable and reliable structural design and combines with advanced technological process which completely conquers the thousands of customers of the micro slag grinding market.
Here the engineers of researching vertical mill in Hongxing Machinery will explain to you the processing course of the micro slag grinding in detail.
1. The determination of dimensions and basic parameters including the water content of wet slag, materials feeding granularity and the output of the grinding mill.
2. The main engine equipment, the output and power of the vertical mill, and the processed air quantity of the dust collector.
3. The storage of the materials.
(1) Wet slag: Generally speaking, the wet slag is directly sent from the slag storage yard by the belt conveyor into the wet slag cabin in the plant, and the wet slag cabin cannot be too large, and as long as it is able to hold the materials for four to eight hours in order to prevent the wet slag from caking unused for a long period of time. In addition, it is not proper to convey the wet slag with elevator because it may stick or bond in the hopper which will reduce the conveying capacity. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like ore processing plant, Henan Hongxing is always doing the best in products and service.breaker machine: http://www.crusher-machine.com/n216.html
(2) Micro powdering of the slag: If the source of the slag is single and the quality is stable, the company may build a homogenization bank; and if there are many sources, then the company need to build two homogenization banks in order to make sure that the products delivered from the plant are stable in quality.
4. Package:
Since the micro slag is directly used in the concrete mixing station, more often than not, they are transported by the train, car or ship in bulk. If it is necessary to use bag package, the big bag package is often used and small bag packaging is not suitable from the point of reducing the cost.
Motor runs under the condition that speed reducer drives Nether millstone. The materials fall into the center of device through lock air feeder, and hot air comes into mill through air inlet. Under the function of centrifugal force, the materials when they come by the annular chute. The grinded materials will be taken up by air circulation and the bigger powder will fall down for regrinding. Qualified powders will be collected by collecting device as to be final product. Materials containing water will be dried when they contact with the hot air. Different humidify materials can be dried to the requirement through adjusting the temperature of hot air. Adjusting the separator can get the required fineness powders.
