High Efficiency Vertical Slag Mill | Slag Mill, Slag Grinding Mill
Description
Vertical grinding is a high-quality equipment professionally applied in the slag processing industry. As a professional manufacturer of vertical grinding, Hefei Hengcheng produces high-quality vertical grinding equipment for the slag industry with high practicality and application value. It is an advanced equipment for improving the application of slag secondary resource treatment. For customers, when choosing slag vertical grinding, they need to consider the following aspects.
Firstly, it is necessary to understand the manufacturing capacity and scale of the manufacturer. An excellent modern production enterprise with strong production capabilities in terms of production process, production scale, and technological application. The quality of the products produced is more guaranteed, and the after-sales service provided is also more comprehensive and comprehensive, without causing customers trouble in post sales disputes.
Secondly, product quality is very important. This is a purchasing factor that almost every customer must first consider. The slag vertical mill is a preferred equipment manufactured by Hefei Hengcheng through years of dedicated research and production experience, and the introduction of advanced production processes. It integrates drying, grinding, grading, and transportation, with strong adaptability to materials, low comprehensive investment cost, outdoor layout, low construction cost, low vibration and noise of the entire system, full negative pressure operation, and no dust overflow. It can basically achieve a dust-free processing workshop.
Thirdly, it is after-sales service. After sales service is a strong support and technical guarantee for the entire production line. We have a skilled, strong, and service-oriented after-sales service team that can provide strong pre-sales, in sales, and after-sales service and technical support based on the specific production status of customers on site, ensuring that each production line can play a greater role and create greater value.
Working principle: The electric motor drives the grinding disc to rotate through a reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and qualified fine powder is discharged with the airflow, Collect in the powder collection device, which is the product. Materials containing moisture are dried during contact with hot gases to achieve the required product moisture.

Advantage
(1) The material is mainly broken and ground by the weight of the grinding roller and the pressure of the pressure device. During the grinding process, the material is always subjected to the pressure of the grinding roller, and the rolling between the grinding roller and the grinding disc is not pure. The material is subjected to multi-directional stress, thus improving the grinding ability and efficiency of the mill.
(2) Due to the fact that the material comes into full contact with the hot gas after entering the mill, and is then suspended in the hot gas after grinding, it can effectively exchange heat energy and dry the material while grinding.
(3) The grinding pressure of the grinding roller is provided by the hydraulic system, which is transmitted to the grinding roller through the pressurization device and rocker arm device, and then applied to the material. By adjusting the pressure of the hydraulic system, the size of the grinding pressure is changed to meet the requirements of grinding materials with different hardness.
(4) In order to avoid severe vibration caused by direct contact between the broken material grinding roller and the grinding disc during the operation of the mill, there should be a certain gap between the grinding roller and the grinding disc. Therefore, a limit device was designed to control the size of the gap, and the thickness of the material under the grinding roller can be known at any time through the limit device, thereby ensuring that the mill operates under safe and economical working conditions.
(5) The roller sleeve and grinding disc lining plate are made of high hardness alloy wear-resistant materials, which have low wear and long service life.
(6) The grinding roller can be flipped out of the machine with the help of an auxiliary oil cylinder, making replacement and maintenance very convenient.
(7) A device is installed around the grinding disc to prevent the wear of the disc seat, adjust the wind speed at the air ring, and ensure the production capacity and economic operation of the vertical mill.
(8) The separator is composed of a frequency converter motor, a reduction mechanism, a rotor, a shell, and other parts. The motor drives the separator rotor to rotate through a deceleration mechanism, and obtains products of different fineness by adjusting the motor speed.
