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.

JXSC sand crushing machine has good effects on crushing dry materials and wet materials. However, it is not suitable for crushing semi-dry and semi-wet materials. Because there are many muds in the semi-dry and semi-wet mud materials, it is easy to agglomerate and stick, block the crushing cavity, and block the material. For semi-dry and semi-wet materials, the mud can be washed off with more water, but the artificial manufacturing machine wear will increase.

Material vertical fall into impeller which high-speed rotating from the machine top. Then, under the action of centrifugal, crushed by shunt impeller around material generate high-speed impact with the other part of umbrella-shaped. After hitting each other, the material will form an eddy between the impeller and casing, and repeatedly hit, friction and shattered each other. Material discharged vertically from the bottom, screening out the required finished product granularity by screening equipment.
Whole Center Feeding The material falls into the impeller through the center of the feed tray, and the initial lateral acceleration is given through the distribution cone, and is uniformly distributed into each flow passage to further accelerate the throwing. After the material is thrown, it will directly hit the material layer on the perimeter guard and the guard plate, or collide with the bounced material. This collision point is relatively close to the casing. The whole center feed has a stronger impact on force and longer stroke. Some materials impact the material layer of the peripheral guard plate and the peripheral guard plate, or the material is hedged, which is a hard landing, so it is advantageous for fine crushing. The whole center feed sand making machine is often applied to the processing of mechanism sand, and the sand formation rate is higher.
Center And Ring Feeding The waterfall flow feed is materials are processed by the distributor or points, and a part falls from both sides, and after falling, a continuous material waterfall is formed around the impeller. If only the material waterfall does not make any sense, which cooperates with the center feed. The accelerated material in the impeller is thrown out at a speed of 70-80 m/s, and the material falls into the material waterfall, causing the material to be milled. Of course, after the materials are exchanged for kinetic energy, some of the materials impact the perimeter guard or the material layer, and another part of the material falls. However, because the object of the first strong impact is the material waterfall. Therefore, the crushing ability is much lower than that of the whole center feed. But the friction and impact between the materials are increased. The center feeding with annular waterfalls falls feeding way is more suitable for shaping the aggregate and less wear.
Due to the natural resources is finite, many countries come to be a shortage of river sand. But construction industries need it. And nowadays various countries have issued documents banning the digging of river sand. So, artificial sand appearance not only solves this problem but also protect the environment.
The large rocks feed into need primary crusher(jaw/impact/hammer crusher) to reduce the size by vibrating feeder. But the crushing materials aren't enough fine, so they need to secondary crushing by sand making machine. In order to make full use of rocks, the sand making plant has a recycling system in primary and secondary crushing.
The artificial sand discharge by VSI sand making equipment should transport to sand washing plant to washing and screening, then dewatering and drying. Finally, we get the good manufactured sand for building materials, highway, railway, and concrete mixing plants. How to improve the artificial sand production?
