There are different types of stone crushers in mining industry such as jaw crusher, cone crusher, impact crusher, and sand making machine. This article will tell you how to maintain the 4 types of rock crushers and how to efficicently improve their performance.
Many stone crusher operators have a common coception that is "don't-fix-it-if-it-isn't-broke". They may want to save cost at the begining while the consequence is that they have to spend more money on repair and face interuption on production. That's why I always say that preventive and predictive is very important for all types of stone crusher.
Preventive means that by making regular checklist and inspections to keep crushers in good condition. Maintenance checklist is usually set up on a daily (8 hours), weekly (40 hours), monthly (200 hours), yearly (2,000 hours). Only doing that, can you prolong the machine's life span and maximize its value in crushing process.
Predictive refers to mornitoring the condition of crusher when it is running. By some maintenance tools such as lubricating oil temperature sensors, lubricating oil filter condition indicator, you can timely draw the machine data so that making a comparison between the real situation and normal state. Predictive can help you find problem early then timely removing thers issues before demage occuring.
Ractive means that even if your crushers have got problems, as long as you adopt correct solutions to respond, you still can get your machine back to normal. Next, I'll introduce important skills to maintain your equipment.
The cone crusher in the secondary or tertiary crushing proccess often fractures medium-hard or hard rocks like pebble, quartz, granite, etc. It is easy to get premature crusher failure, if operators cannot make a correct and timely inspection and maintenance.
Mantle in moveable cone and concave is fixed cone. Due to directly contacting with rock materials, the two wear parts need frequent maintenance and protection. So operators have to know the preparations and maintaining skills.
The working principle of impact crusher is that the spinning rotor under the driving of the motor can genetate strong impact force which make blow bars crush stone material into small pieces. Then the crushed material would be thrown by hammers towards, which makes another crushing process "stone to stone".
The sand making machine is also known as the vertical shaft impact crusher. Its working mode is that the material falls vertically from the upper part of the machine into the high-speed rotating impeller. The impeller is one of the important parts of the sand making machine, and it is also the most vulnerable part.
After the materials collide with each other, they will be pulverized and smashed between the impeller for multiple times and discharged from the lower part. The materials crushed by the device have an excellent particle size and are suitable for aggregate shaping, artificial sand making and highway construction.

There are many types of stone crusher equipment on the market. Users who are more familiar with this industry may ask about a specific type of equipment. For new users, it is understandable to ask this question. After all, you must fully understand before buying equipment. The type and performance of the equipment. Here we will explain the commonly used equipment and their positioning.
Before introducing the types of stone crushers, let's popularize the types of sand and gravel production lines. The sand and gravel production lines are mainly divided into crushing production lines and sand making production lines. Explain for everyone.
The jaw crusher is generally used as the head equipment of the production line. The reason why it is qualified to be placed in the head is related to its feed inlet. Its feed is very large, and it can handle thousands of millimeters of stone. Take all the hard stuff.
These two types of equipment are commonly used secondary crushing equipment. The small materials processed by the head crushing equipment are crushed into stones that meet the specifications. You can choose one of the two, but not both. Both types of equipment can handle softness. For materials, the cone crusher is more suitable for processing hard materials, and the counterattack crusher is not incapable of processing hard materials, but the material wears the equipment more seriously, so it is more suitable for processing soft materials. Of these two types of equipment, the price of cone crusher is more expensive than that of counterattack crusher, but the production cost of cone crusher is lower.
Since this equipment is a sand making equipment, also called sand making machine, it is mainly used to treat stones into sand. The feed size does not exceed 60 mm and the output size is adjustable. It also has the function of shaping and produces finished products. Most of them are cubes, with high bulk density, and both soft and hard materials can be processed.
The above introduces you to the traditional fixed production line. This type of production line can not meet the needs of users, so mobile production lines have emerged. The equipment used is a mobile stone crusher. Its characteristics are more flexible and do not require long-term Piling, infrastructure, etc., it can be directly driven to the broken site, or can be transferred at any time. It is convenient to enter and exit the site, it has changed the traditional production method, and it is also environmentally friendly and meets the needs of contemporary environmental protection.
These are the more commonly used equipment for everyone, of course there are many, such as compound crusher, roll crusher, fine crusher, etc., we cannot introduce them one by one here. If you want to know more about stone crusher, you can Consult our online customer service for free.
Impact Crushers: This division is represented chiefly by the various styles of hammermill; also by the cage type disintegrator. Combination Impact and Sledging Crushers. In this class we have the single or double sledging roll crushers. An example of the former is the Fairmount crusher, of the latter, the Edison roll crusher.
Some further subdividing and qualification might be applied to these general classifications, but these, for the most part, are not of particular importance. Pressure crushers, for example, may be divided into two subclasses: the reciprocating, and the continuous-pressure, types. The gyratory and jaw crushers come under the first category, the crushing rolls under the second. Strictly speaking, the gyratory motion is not a reciprocating one, but it is so with respect to any vertical radial plane through the crushing chamber; therefore it is convenient to view it in that light. Some roll crushers, notably the light coal crushing type, have more of a tearing action, as contrasted to the heavy sledging performance of such machines as the Fairmount crusher.
During the same years wherein the industry was concerned with development of larger and still larger primary crushers,another member of the family was born: the single, sledging- roll crusher. The Allis-Chalmers Co. entered this field in 1911, building two sets of 36 dia. x 60 face single-roll crushers, flux limestone plant. Taking the name of its proving ground, this machine was christened the Fairmount crusher. The machine quickly achieved a high degree of popularity, and although its field of application is relatively limited, quite a number of them were in-stalled for primary crushing service. The line was expanded to include smaller sizes, as well as the big 60- x 84-in. machine.
Development of concentration and cyanidation in the mining industry called for finer crushing than was feasible in the gyratory or jaw crushers then available. This requirement was met for a number of years by the double smooth-face crushing rolls, originally known as Cornish rolls. As the mining industry during the period we are discussing was a very active one, the development in this type of crusher had reached a fairly high stage before the end of the century, and some excellent heavy-duty roils were available at that time. That this machine was not used to any considerable extent in the commercial crushing plants of that period was due simply to the fact that there was no demand for the smaller sizes of crushed stone, at least not any more than could be taken care of by the crushing methods then in vogue in such plants. This brings us to the rather significant fact that, while all of the interesting and rather remarkable development we have outlined was going on, very little, if anything, was being done to develop special crushers for secondary and fine-reduction work, other than the work on crushing rolls just described.

The crusher is a machine that is designed such that to reduce the size of large rocks into smaller rocks like gravels. It is not only for that, but it is also used for recycling of the waste materials. Crusher is a multi-dimensional machine. Crusher has the ability of changing the form of material. In rock ores, crusher is used for the reduction in size or for making pieces of a solid mix i.e., composed of different raw materials and these pieces are used for the composition study of different raw materials.
Selection of crusher is quite a complicated process because of the availability of many kinds of crusher in the market. So, during selection keep following points in mind and find whether the crusher is able to do these specific functions or not.
If someone selects a crusher that has more capacity than his requirements, then it will be uneconomical. This is so because as crusher size increases, its fuel burning rate and maintenance cost will be more.
Primary crusher has the ability to receive the crushing material (a material that has to be crushed) directly from the source i.e., quarry thats why these types of crusher are fixed from where the material is taken. Primary crusher is only for the breaking of large stones into pieces (this mean primary crusher is not for the aggregate size material.). Examples of primary crushers are jaw crusher; hammer mill crusher and gyratory crusher. After receiving primary crusher crush the material and produce a new fresh reduce size of the source material. Primary crusher has only functioned up to that point.
Now a secondary crusher comes into action and further reduces the size. In secondary crusher some sizes of stones may pass directly from sieve number 4. Examples of secondary crushers are cone crusher, roll crusher and hammer mill crusher.
At the end tertiary crusher reduces the size of crushed pieces very much to the required size and it also brings the fineness to the crushed material. Tertiary crushers are at the job site andthese are small in size. The material is first transported from source with the help of a dump truck. Some tertiary crushers are roll crusher, rod mill crusher and ball mill crusher.

The hammer crusher mainly rely on the impact action to crush raw materials into small size. Thus, it is a necessary equipment for many industries, especially pharmaceutical, feed, food, coating, chemical industry. Here, the hammer crusher from SEEC is a specialized crushing equipment for fertilizer production. Especially for large scale fertilizer production, most customers choose to use this kind crush machine. When the raw materials enter in this machine, they can be crushed for many times. Until the materials are smaller than the clearance of the sieve bar they will be discharged from the clearance and finish crushing process.
This crush machine is the ideal crushing equipment to crush the corn stalk, straw, peanut husk, bean stalk, cotton wastes, branches, leaves, sawdust, etc. If the compost material contains too much water, the crushed organic material can help absorb the excess water to adjust the humidity of raw materials. So, if you want to make high quality fertilizer, this crusher is necessary to you. Besides, this straw crusher is easy to operate and would not occupy too much space in fertilizer plant.
Chain crusher is suitable to crushing nubby materials in compound fertilizer making process. Meanwhile, it is also suitable for the crushing of returned materials in fertilizer production. Its installation form is divided into vertical and horizontal. For vertical chain crusher, it has single rotor. While horizontal type it has double rotors.
Urea crusher is used to crush all kinds of single chemical fertilizers with water content less than 40%, especially for materials with high hardness. Before you use this crusher, you should place this machine in a certain position in the workshop, and it can be used when connected to the power supply. The fineness of the crusher is controlled by the spacing between two rollers, the smaller the spacing is, the finer the fineness will be.
Cage fertilizer crusher belongs to medium-sized horizontal fertilizer crusher machine. It is designed according to the impact action to crush materials. When it is working, the inside and outside cages rotate in the opposite direction with high speed, then the material is crushed from inside to outside by the impact of the cage. The crusher has the advantages of simple structure, high crushing efficiency, good sealing performance, stable operation, easy cleaning, convenient maintenance and so on.
