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.

In order to crush rocks and extract gold, you will need the right equipment that can achieve this quickly and efficiently. That being said, utilizing rock crushers will help prevent you from missing the opportunity of hitting paydirt. Portable rock crushers will change the way you prospect for gold and with several options available, making sure that you select the correct product will be invaluable.
The term itself is pretty self-explanatory. These machines are designed to crush any type of stone from quartz to limestone and everything in between. How much is able to be processed per hour will depend on the model you purchase.
The intention of small rock crushers, such as those we have here at Kellyco, is to allow you to extract more gold instead of leaving any paydirt behind. The amount of gold that can be contained within rocks in areas you didnt know were there may surprise you. However, without a rock crusher in your arsenal, you will never be aware of what was left behind.
Portable rock crushers use a very simple approach, power. With various sized engines available depending on the model, these machines are designed to take small rocks and, thanks to a huge amount of pressure and power, crush them down and allow you to process them through your sluice box.
The aim of any small rock crusher for sale is to be able to break that rock down into a fine powder. In doing so, it will be able to pass through a classifier before going through the sluice box and any gold can then be separated. Even relatively small pieces of rock that are left intact could lead to you missing out on some gold, and when you know you have hit paydirt then you hardly want to leave anything behind.
Most models, including the Keene G-Force rock crusher, will use a hopper box with gravity to move the rocks through the crusher. The rock is fed into the hopper box and then moves into the central compartment of the crusher. A huge amount of force effectively smashes the rock at high speed and the greater the force then the finer the powder. With that in mind, the power of the engine contained within the rock crusher will be important.
With several options available, knowing which are the best rock crushers for sale will make your job of identifying the right product for you easier. Of course, budget may play a part but Kellyco does have a number of small portable rock crushers for sale across a wide price range.
There are several key points to consider when looking at purchasing a portable rock crusher. First, there is the volume of rock that can process for up to an hour. With some capable of producing over 2 tons of powder, also known as grind, this should be more than adequate for the majority of treasure hunters.
Another point to remember is the size of rock that the crusher can handle. These kinds of rock crushers for sale are not designed to take large boulders and break them down on an industrial scale. Instead, we are talking about rocks that are around one inch in size that can be effectively smashed in seconds. Once again, we recommend that you check the maximum size that the model you are looking at can take before making your purchase.
The best rock crushers for sale will contain a large hopper box, be capable of crushing a substantial amount of rock in one hour, and break things down into an easy to manage powder. As long as those points are met, then you should not have any problem extracting as much gold as possible from your expedition.
There are several additional features that deserve to be mentioned with a rock crusher. For example, you need to examine how a particular model is powered. With both gas and electric available as options, it should be easy for you to get things started. As a side-note, the gas version is often regarded as being cheaper to operate. Also, we have to think about transportation. These machines are not the lightest around which is why there are lighter models, such as the Keene trailer mounted crusher, on the market. This does make it easier to get to those more remote areas that you may wish to venture to on your expeditions.
You may wish to consider looking at the process that the rock crusher uses in order to deliver the powder. Different models may put the rock through various processes with each stage resulting in something even finer than before.
Finally, there has to be the question of replacing parts even when you are out there in the wild. Cleaning the machine and clearing it of debris is important or it may result in becoming clogged. However, models that have been manufactured by Keene will all be easy to adjust and maintain so this shouldnt be a problem.

Rock crushers have a wide range of suitable material to choose from, whether its soft or hard, or even very hard, rock crushers can reduce those large rocks into smaller rocks, gravel, or even rock dust.Here are some typical materials that break or compress by industry crushers, such as Granite, quartz stone, river pebble, limestone, calcite, concrete, dolomite, iron ore, silicon ore, basalt and other mines, rocks and slag.
Understanding the stages of crushing process and the types of crushers that best fit each stage can simplifies your equipment selection. Each type of crusher is different and used to achieve a certain end result.
Similarly, a certain output is expected at the end of each crushing stage for the next phase of the process. Aggregate producers who pair the correct crusher to the correct stage will be the most efficient and, in turn, the most profitable.
A jaw crusher is a compression type of crusher. Material is reduced by squeezing the feed material between a moving piece of steel and a stationary piece. The discharge size is controlled by the setting or the space between those two pieces of steel. The tighter the setting, the smaller the output size and the lower the throughput capacity.
As a compression crusher, jaw crushers generally produce the coarsest material because they break the rock by the natural inherent lines of weakness. Jaw crushers are an excellent primary crusher when used to prepare rock for subsequent processing stages.
Although the chamber is round in shape, the moving piece of steel is not meant to rotate. Instead, a wedge is driven around to create compression on one side of the chamber and discharge opening on the opposite side. Cone crushers are used in secondary and tertiary roles as an alternative to impact crushers when shape is an important requirement, but the proportion of fines produced needs to be minimized.
An impact crusher uses mass and velocity to break down feed material. First, the feed material is reduced as it enters the crusher with the rotating blow bars or hammers in the rotor. The secondary breakage occurs as the material is accelerated into the stationary aprons or breaker plates.
Impact crushers tend to be used where shape is a critical requirement and the feed material is not very abrasive. The crushing action of an impact crusher breaks a rock along natural cleavage planes, giving rise to better product quality in terms of shape.
Most aggregate producers are well acquainted with the selection of crushing equipment and know it is possible to select a piece of equipment based solely on spec sheets and gradation calculations. Still, theoretical conclusions must always be weighed against practical experience regarding the material at hand and of the operational, maintenance and economical aspects of different solutions.
The duty of the primary crusher is, above all, to make it possible to transport material on a conveyor belt. In most aggregate crushing plants, primary crushing is carried out in a jaw crusher, although a gyratory primary crusher may be used. If material is easily crushed and not excessively abrasive, an impact breaker could also be the best choice.
The most important characteristics of a primary crusher are the capacity and the ability to accept raw material without blockages. A large primary crusher is more expensive to purchase than a smaller machine. For this reason, investment cost calculations for primary crushers are weighed against the costs of blasting raw material to a smaller size.
A pit-portable primary crusher can be an economically sound solution in cases where the producer is crushing at the quarry face. In modern plants, it is often advantageous to use a moveable primary crusher so it can follow the movement of the face where raw material is extracted.
The purpose of intermediate crushing is to produce various coarser fractions or to prepare material for final crushing. If the intermediate crusher is used to make railway ballast, product quality is important.
In other cases, there are normally no quality requirements, although the product must be suitable for fine crushing. In most cases, the objective is to obtain the greatest possible reduction at the lowest possible cost.
In most cases, the fine crushing and cubicization functions are combined in a single crushing stage. The selection of a crusher for tertiary crushing calls for both practical experience and theoretical know-how. This is where producers should be sure to call in an experienced applications specialist to make sure a system is properly engineered.
