Gist on Correct Operation and Maintenance of Roller Crusher

2016-10-25

When the PF Impact Crusher crushes the materials, the roll surface will gradually abrade, for this reason, the crushing machine must be fed with materials in the direction of the length of the roller and in a regular manner. If the materials are fed into the crushing machine in an irregular manner, ring groove may show on the roll surface which may influence normal work of the crushing equipment and the product granularity may not be even. When feeding materials, the feeding material not only needs to feed the crushing machine in an even and continuous way, but that the length should be the same with the length of the roll.
As for the cone crusher spare parts, regular repair and maintenance of the roll surface is very necessary. Sometimes there is equipped with grinding wheel on the machine shell of the plain roller crusher, so when there is pit or groove on the roll surface, there is no need to dismantle the roll surface but directly grind and repair the roll surface, and at this time overlaying device may be needed to equip on the crusher. Some plain roller crusher has roll automatic axial reciprocating motion device, thus making the abrasion of the roll surface even.
When the teeth of the crushing equipment is abraded to a certain degree, the worker should change or repair it in order to prevent the problem that the product granularity is not even, energy consumption increases and the production capacity decreases.
After the roll surface is abraded, the material discharging mouth may increase, for it will be necessary to adjust the movable roll. When adjusting the roll, the two rolls must be kept parallel. As for the double-roll crusher which the movable roll is installed on the rocker arm or with the hydraulic Lead ore crushing machine, when moving the movable roll, it will automatically ensure parallel of the two rollers.
In order to ensure normal work of the roll crusher, the lubricating condition of the bearing must be checked regularly. The movable bearing should be added with a grease cup and the antifriction bearing should be regularly added with dry oil for lubrication and sealing.

Discourse on the Method of Preventing Liner Wear of Ball Mill

2016-10-19

Ball mill is one of the essential parts of mineral processing equipment. Many users of ball mill complain that the liner plate of a Silica sand grinding mill is with short service life and a high production costs. SBM Mining Machinery summed up key factors influencing the liner wear of a ball mil based on years of production experience, which as a reference for the users of ball mill. Hope it can help the users avoid a similar situation in production and prolong the service life of ball mill liner plate. The key factors influencing the liner wear of a ball mill generally include the following several points:

1, The impact of media material

The generally used crushing media material include: various mine materials (manganese, copper, tungsten ore, chrome ore, etc.), various types of stone (limestone, granite, gneiss, basalt, gray rock, etc.) and industry coal used in power. The hardness of the media is the main basis that determines the liner plate wear, the higher hardness of the media, and the shorter service life of the liner; on the contrary, if the media is with a lower hardness, the service life of the liner will be prolonged.

2, The impact of operating conditions

1) Eliminate defects not timely.
2) Adjusting undeservedly makes the Ball Mill running at short positions.

3, The impact of liner material

The main parameters affecting the anti-wear effect is matching of the two index of hardness and impacting toughness of liner material. If the liner plate has a higher hardness, which means it has a good wear resistance, and the two factors basically is a proportional relationship. The impacting energy depends on the size of the diameter of steel ball and grinding tube.

4, the impact of the ball mill’s designing and manufacturing and the installing quality.

The performance of the lining plate generally include the following two: one is to protect the cylinder; another is that the liner plate rotates at a specific speed to raise the ball to the required height to achieve the desired effect.
The quality of the liner plate is also direct factor affecting the normal operation of the mill.
Those above are the main factors affecting Ball Mill Development Prospect liners; we recommend that you should firstly consult the expert before you buy a ball mill. And you’d better go to the manufacturers with strength production and reputable brand purchase.

An Analysis on the Development of Ball Mill

2016-10-18

Since its emergence, the Ball Mill has experienced uneven development over nearly one hundred years due to different research methods owing to the different economic development levels of nations. Although the efficiency of ball mill is very low, it is extensively applied.
Domestic research on energy is basically carried out individually and empirically. There haven’t been systematic research methods to gain due achievements. The research covers the optimal application, the factors influencing efficiency of ball mill, optimal simplified structure form, transmission mode, steel ball size, matching ball quantity, rotation speed, power, plate, etc.
Although ball mill has basically completed its localization, the research and analysis on the ball mill has been staying on traditional level. The traditional design of Ball Mill For Gold is based on the calculation of the thickness of grinding machine barrel. To reinforce plate arrangement, the method of analogy can be adopted. If we simplify ball mill as a beam and calculate the strength according to the plane bending, torsion and deformation, the result can be too rough. The reasons are as follows:
1 There isn’t much difference between the diameter and barrel length, so it doesn’t accord with the assumption of simplified supporting beam ( the beam length can be over five times the maximum size of the cross section )
2 The cylinder body is a kind of plate shell structure, and the deformation under stress is much complex.
3 The cylinder body contains a feed port, a discharge port and lining plate, which may cause stress concentration. So only fine calculation can make nearby stress distribution clear.
So the traditional design of Calcite powder grinding mill tends to be conservative, and the intensity far exceeds the working condition. Since there is a lot of strength reserve, SBM has made detailed analysis on it. We will continue to make an effort to moderate and research brand new product, which will benefit the long term development of the enterprise as well as the society.
