High yield and stability of ultra fine grinding mill can get better benefit

2017-11-21 15:29:14 | 日記
The working process of ultra fine mill for the requirements of the production process is stable, high yield, so as to bring better efficiency and benefit for the entire production line, this point is any users expect to see the effect, but in the actual production process, there are a lot of factors that will make up the machine the steady and high demand, here is to analyze the factors that cause this phenomenon which has the problem.

In general, ultrafine grinding mill in production, in order to achieve high and stable yield effect, not only has a relationship with the entire production line equipment, and also the wear condition of operation of the sealing system, parts of the relationship and the use of lubrication system, so the device can not achieve stable high production requirements, need to start from these to solve.

Different factors are not the same for production, such as sealing system of superfine grinding machine, if the sealing effect is not good, will cause the dust can not overflow, this phenomenon will cause the environment, and dust into the interior of the device and increase the wear at the same time, the lubricating effect is reduced, these the situation, will cause serious wear and tear parts, this phenomenon will, so that they will not help the material good crushing and powder selection process, then there will be decline in efficiency.

In view of this, in the production of superfine grinding process, the need for strict operation, and regular inspection of the sealing and wear factors, and then into the material, must also comply with the requirements of production equipment, in order to reduce wear of the situation, reduce the failure of the production, and the effect on efficiency the.

The article mainly introduces the process of grinding production in fine, factors appear to the stable high yield phenomenon which has the problem above, mainly introduced some elements of the seal system, and other related parts of the wear condition, and then analyzed in the production of proper operation and inspection can reduce the occurrence of wear of the situation, to assist the smooth production, and achieve a better capacity.

Four improvements have improved the Raymond mill structure performance

With the continuous development of the powder industry, the market demand for ultrafine iron Raymond Mill is also increasing. As the main equipment for grinding in the powder industry of China, ultrafine grinding mill of iron ore is an inevitable trend for the development of "high reliability, energy saving, precision and automation".

Due to the problems of low fineness, high power consumption, large noise and low system efficiency, the traditional superfine Raymond mill has been bothering the mineral processing enterprises and the equipment manufacturers of Raymond mill. Shanghai sebang machine mining equipment manufacturing limited liability company after many years of accumulated experience, on the basis of the improvement of Raymond mill, independent research and development and production of a new generation of ore superfine Raymond mill, effectively solves the technical problems of traditional superfine Raymond mill, Raymond mill from the increased price.

Four improvements of the structure of ultrafine Raymond mill are as follows:
First, the structure of the main shaft and the plum blossom frame is conducive to stable structural transformation, so that the operation is stable.

Two. The traditional part of the analysis machine is changed into two isolation from the inside of the hanging cavity of the vertical hanging hoist, which enhances the stability and durability of the machine.

Three. in the grinding zone, the grind material is always gathered in the grinding zone effectively processing, improve grinding efficiency, but also updated the roller structure, the grinding roller and the roller shaft can be complementary in the rotation of the operation, also can make the revolution, its effect and durability.

Four. in the ventilation part, the bellows and the air duct are changed from the original horizontal bottom to 30 degrees to the center, forming a bucket to ensure that the bellows and the air duct are unobstructed and unobstructed, so that the air volume is always maintained, and the host mill is in high efficiency.

The Energy Saving Design of Raymond Mill

Raymond mill is a kind of mineral processing equipment commonly used in mineral processing plant. It is also a high energy consumption equipment. Energy saving design and parameter optimization design of Raymond mill are of great significance to reduce energy consumption and improve beneficiation efficiency.

Raymond mill mainly from the starting mode, lubrication mode, bearing type, liner structure and form, Raymond mill speed ratio and other aspects of energy saving design. Raymond mill is made by state industrial science and technology group. It has many characteristics in energy saving design. The equipment must be operated according to the design requirements in production.

1. Design of starting mode
Soft start pneumatic clutch. It can realize the starting of the synchronous motor Raymond mill, and make the motor start without load. When the speed is stable, the clutch is combined and the Raymond mill is started. This can shorten the starting time of the motor itself, start easily, reduce the impact of the starting current on the power grid, and also reduce the installed power of Raymond mill.

2. hydrostatic bearing and static and dynamic pressure bearing design
It is a common design for Raymond mill to use dynamic and static pressure mixed lubrication bearings instead of ordinary bearings..

(1) in the Raymond mill before starting, high pressure using lubricating oil will float the shaft neck of 0.2 ~ 0.3mm, it can greatly reduce the starting load, and then start, after which can make the shaft and bearing by external supply, with certain pressure bearing oil film is completely separated from the start, when the shaft neck reach enough speed, namely the use of hydrodynamic lubrication bearing.

(2) when the Raymond mill is shut down, let the pressure oil float the shaft neck slowly on the bearing bush, so as not to abrade the bearing bush. This ensures that the journal is started under the condition of pure liquid friction. The friction resistance is small, the power consumption is small, and the transmission efficiency is high.

What are the Performance Features of VSI Sand Making Machine?

2017-11-16 10:26:37 | 日記
VSI sand making machine is an indispensable machine of the sand making production line and is a practical and reliable sand making machine.
