No Picture

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.

How to choose the suitable ultrafine grinding mill has become a problem. Here's a little sorting out some of the attention of the purchase of ultra-fine grinding, I hope to help you.

As a powder processing enterprise, many factors need to be considered in the selection of ultra-fine grinding equipment.

First of all, it is necessary to consider the quality of the mill products. At present, there are many ultrafine mill manufacturers, the strength is uneven, the product is good or bad. In the choice, customers should pay attention to whether the product meets the standards, including timber and so on, but also consider the size of the enterprise, equipment production and processing conditions are qualified, and the equipment is in line with the relevant environmental standards. These are the priorities that need to be addressed.

Secondly, the technical ability of suppliers. Different materials have different milling technology and equipment. According to the special needs of users, equipment suppliers can provide special specifications or configuration products. This is not only related to the user to buy the right product, but also means that after the purchase, equipment suppliers can provide the corresponding after-sales service capabilities.

Thirdly, it is necessary to investigate whether the suppliers of ultra-fine grinding mill have perfect after-sale service system. It includes equipment pre construction, equipment installation, commissioning and training, commissioning guidance and after-sales maintenance, will encounter a series of technical problems.

Milling equipment may cause environmental pollution, ultrafine mill in order to meet the requirements of environmental protection, the need to install dust removal equipment, used to collect dust, to prevent the spillover phenomenon, generally speaking, in the process of using the fittings is not immutable and frozen, if used improperly or without reasonable maintenance, so there will be damage to the phenomenon, in view of this phenomenon this article, on the matters needing attention are introduced.

Generally speaking, in the production of ultrafine mill, precipitator hopper will be a lot of dust slowly landing, flying two times on against the current leakage caused by dust and air landing, and so many lifetimes, the ash discharging port if there is leakage phenomenon, the dust concentration of dust in multiples higher than the dust concentration at the inlet, this may make the equipment removal efficiency decreased.

In production, the use of dust, to prevent the gas in the bag chamber is cooled below the dew point, especially when the use of dust collector under negative pressure, but it should be noted that, due to the dust source gas with high concentration, even if only 1% short escape will exceed the emission scale, so for this point, if we want to ensure the environmental performance of ultrafine grinding machine, to prevent the overflow phenomenon of dust source gas.

The other is dust removal equipment shell often have air leakage into the bag, the gas chamber temperature is lower than the dew point, the bag will be damp, dust is not loose, but which attached to the bag, the fabric cleaning holes blocked, caused by failure, the dust removal system pressure is too large, no law of succession operation, some cannot paste bag dust, so this is one of the reasons of equipment can not meet environmental requirements, when in use, for this phenomenon, should be timely treatment.

Because of the two crushing chambers, the dual-chamber gold ore crusher has the advantages of large crushing ratio, high production capacity and strong adaptability to technology. It is widely used in the crushing operation with the compressive strength below 250 MPa. The two crushing chambers of the crusher are symmetrically distributed around the eccentric shaft. The crushing force in the chamber is an important parameter that affects the crusher's production capacity. In this paper, the analysis of the variation of the crushing force in the crushing chamber can provide theoretical basis for the structural optimization design of the gold ore crusher. The work of the two crushing chambers alternates in succession, that is, the crushing chambers are alternately crushed and discharged, and the process continues to reciprocate. So you can take full advantage of the motor energy, production capacity increased nearly 1 times, and the unit power has dropped significantly. Activities of tooth plate movement so that the cross-sectional shape of the crushing chamber changes compression stroke occurs, the application of crushing force on the material to achieve the purpose of crushing the material. The analysis of the movement of the tooth plate shows that the movement of the upper and lower parts of the tooth plate is not synchronized, and in some intervals it is deviated. In some sections, the movable tooth plate can only exert the breaking force locally, and the rest does not apply the breaking force. In some sections, the material is only compressed and does not generate the breaking force. Broken stroke crushing force, crushing discharge does not produce crushing force, so in different regions of the size of crushing force is different. In addition to the size of the crushing force and crushing cavity tooth plate movement, but also with the way the material is broken and the shape of the material particles. In the crusher, there are often two or more than two kinds of force, so the value of the crushing force is different. Such as gold ore crusher, due to the material in the tension state and broken, so the pull force is mainly broken force. Through the above research on the variation of crushing force, it is of great reference significance for the reasonable determination of crushing force.
