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 the face of such a dazzling market, how to choose the production equipment suitable for users' actual needs among the numerous equipment brands of many machinery manufacturers is a big problem for many large and small enterprises.

Attrition scrubbing is the process where a mineral is scrubbed primarily by the action of the slurry particles impacting one another. Attrition scrubbers, also known as Attrition Cells, are relatively simple devices. They consist of a tank, impeller system and drive system. Generally, the tank is PE lined and can be either square or octagonal. The impeller system is PE coated and normally consists of two sets of impellers with opposing pitches. The v-belt drive system is designed to effectively transmit the power to spin the shaft and impellers. The most important function of the attrition machine is the scrubbing of particle scrubbing of particle surfaces to remove film or coating.

Vertical Compound Crusher, as known as vertical plate hammer sand machine, is a new type of vertical sand machine. It is a new generation of sand machine equipment developed and produced by our company.
Two-stage Hammer crusher is also called double-rotor hammer type fine crusher.Two-stage crusher is equivalent to combination of two hammer crushers , two-stage crushing at one time, so it can get big broken ratio, generally the output size is below 3mm.
Hammer Crusher is a rock crusher used in various industries to reduce the material size, such as limestone, coal, slags, gypsum, glass. It uses of high-speed rotary hammer to impact the ore, the finished product size is adjustable by controlling the grate openings, rotor speed, hammer capacity, etc.
