Here We Tell You How To Raise Raymond Mill Productivity

Raymond mill is used for grinding the barite, limestone, kaolin, porcelain clay, and slag, etc, below scale 9.3 of Mohs hardness and 280-odd sorts of non-inflammable and non-explosive stuff in the trades of mining, metallurgical industrial, chemical engineering and building material for high fine powder generation and processing. The product size is adjustable in the range of 80-325 (600 the largest) meshes. It is possible to product 30-80 mesh coarse powder through special device in the machine.

We are concerned about the improvement of raymond mill efficiency.Here we would like to tell you how to improve the efficiency.

1.We should position the feeding size,product size,speed of the center shaft,grinding roller and the grinding ring size accurately.We can improve the grinding efficiency to ensure a uniform powder fineness according to the needs of the grinding fineness.

2.It is important to provide the continuous feeding which could avoid the inappropriate materials into the grinding chamber.It could achieve the continuous production to improve efficiency.

3.Different materials have different hardness.This feature decided what we should do to ensure the right configuration.The materials with same shape and same appearance should be sent to the grinding chamber concentratedly.If we mix the materials to grind,it is easy to cause the production instability,thus to reduce the efficiency of raymond mill.

4.We should know more about the minimum crushing size of the materials and we could not ignore the nature of the materials.Only though this,we could choose the right size of the machinery.

We should do our effort to do the best configuration to achieve the maximum efficiency of raymond mill.It is necessary to achieve the optimal allocation of all possible factors, which will improve the material handling capacity.So that the material between the roller and grinding ring could get full grinding to speed up productivity.

Simple Generalization Affecting Ball Mill's Velocity

ae we all know ball mills are widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.What are the indeed factors affecting ball mill speed? How to make full use of ball mill?

In different mineral industry, the effects of ball mill speed are different. For example, in coal mine industry, the speed of the ball mill is directly influencing the movement condition of the ball and coal sheet. It also influences coal grinding process. If the rotary speed is very low, steel ball and coal sheet cannot be taken up, only the lower mill is rolling, the coal output is small. Instead, if the speed reach high, the centrifugal of the ball and coal is greater than the gravity. The ball and coal sheet will rotate together with the drum, losing the role of grinding coal sheet. Rotary ball mill speed can make the ball in the rotary drum achieve maximum hoisting height, and then the ball reach the biggest impact, grinding effect is perfect. However, in ball mill practical work, its speed is limited by transmission device speed and external other conditions. The ball mill is impossible to achieve optimal height, it is generally close to each other.


In fact, whether the ball mill, energy-saving ball mill, large-scale ball mill, or the planet ball mill used in college laboratory, cement ball mill in cement industry, their working principle is similar basically. Therefore, the factors affecting their speed have something in common. The working principle of ball mill is driven by revolution and auto-rotating, crushing the samples by the friction force and percussive force in the grinding warehouse. The higher speed, the heavier friction and percussive. Generally, discharging grain is in direct proportion to the ball mill speed.


From the above, we know the importance of the ball mill speed in its daily work. Consequently, the speed of ball mill should be set up to maximum to improve the grinding efficiency.
