Under normal condition, soft material chooses the long lining plate, while the hard material chooses the short lining plate.

2. The feeding size of raw material. The sealing side of feeding size of raw material should not exceed 10% of the discharge port. Different raw materials have different performance characteristics, compression strengths, harnesses and fragilities. Then the crushing method also is different. The customer should choose the right crushing way to get the best crushing effect.

3. The particle size of input material and output material. The bigger the input size is, the larger the output material size. Therefore, we should choose the jaw crusher with different model according to the actual working condition.

The Technology Development of Jaw Crusher

Jaw crusher, including simple swing jaw crusher machine and complex swing jaw rock crusher two types,They are similar in their works, the trajectories of moving jaw have bigger difference.Simple swing jaw crusher,because of the moving jaw is hung on the supporting shaft,so when the moving jaw makes reciprocating motion,the trajectories of each point on the moving jaw is circular,and under the horizontal mining jaw crusher stroke is small,and mobile jaw crusher plant at the bottom of the moving jaw (row ore mouth) is the largest.Because of falling into ore crushing cavity,the upper are big ore block,It can not meet the necessary amount of compression,ore crushing large deposits of the upper,to crush many times repeatedly,It can be broken.Crushing load is mostly concentrated in the lower part of the crushing cavity,the jaw crushers china didn't work,which reduces the crusher production capacity.

Jaw crushers work part is two pieces of jaw plate, one is the fixed jaw plate (fixed jaw), vertical (or top slightly camber) fixed before in the body wall, and the other one is movable jaw (moving jaw), position tilt, and fixed jaw plate is formed under the big small crushing cavity (working cavity). Activities for suppressing the jaw with standard cone crusher fixed jaw do periodic reciprocating motion, and sometimes separate, sometimes close to.

Jaw crusher is suitable for all kinds of mok's hardness below level 7 materials coarse, medium and small.When it is used to finely, appropriate chooses finely jaw crusher.On the use of jaw crusher production process,We should control the feeding speed device and screening and inspection screening in advance,It can make the product granularity and the crushing reduce,improve the quality of broken products.

It's Essential to Planned Repair for Jaw Crusher

Joyal Jaw Crusher Improves Production Efficiency

Jaw crusher machine has smashing ability with other crushers in common, also different from them, however, all of them are widely used in metallurgy, mine, chemical engineering department, cement, building materials, electric power and railway etc.

The jaw crusher for sale is mainly used for crushing the stones of which largest compression resistance is 320MPa. This series is complete in specifications and the first choice of primary jaw crusher plates crushing equipment. Its structure iseasy and solid. It is easy to maintain and enjoys satisfactory performance.

After the purchase of jaw crushers china, there will be no big problem if the machine is used frequently. However, if the machine is stored for a long time without using, it will cause some problem to itself. Some cannot boot and some may rust which can influence normal work. So we should pay attention to some points when we are storing the jaw crusher specifications.

Good quality and stable running can greatly shorten repair time and improve production efficiency. In addition, in the security aspect, it eliminates hind dangers and reduces unnecessary lost. Engineers of Joyal Machinery make in-depth research on jaw crusher; improve its structure and reduce its energy consumption.

How Can Jaw Crusher Stored for a Long Time

In the previous, over-exploitation of minerals has caused great pollution and resource waste, the main reason for which is the un-advanced crusher machines. It is estimated that the only way to solve the problem is produce high-performance equipment to meet the market demands. Jaw crushers machine are most widely used in mining machinery. It is used as primary crusher in mining exploitation. Because of its important role, its performance has great influence on the quality of the whole rock processing.

Jaw crusher for sale, also known as the tiger's mouth, its crushing chamber is composed of the movable jaw and quiet jaw, and simulates animals' two jaw to crush materials. The advantage of mobile jaw crusher plant is obvious in the mineral primary crushing, bulk material crushing, save energy, less noise, so it is widely used in mining, building materials.

Firstly, we should pay attention to the storage location. Long-term unused jaw crusher supplier is at best kept in dry room. If there are special circumstances that the jaw crusher is needed to be located outside, we had better choose a flat ground and cover the ground with board. After parking, coat the jaw crusher with a cloth. In regard to the arrangement and layout of the location, we shall ensure that any moves in or out of a mechanical are not affected by other machinery.

Secondly, remove the battery. When the jaw crusher is stored for a long time, remember to remove the battery. Place the battery in a dry and freeze-proofing spot and keep the surface clean and dry. It is forbidden to put conducting objects on the battery. While dismantling the storage battery, cut off the cathode lines at first and then cut off the positive lines. However, it is right to connect the positive line hydraulic cone crushers at first and then connect the cathode. Lead-acid battery should be charged once a month.

Thirdly, engine processing. Before the jaw crusher storage, let out the cooling water inside the engine and replace the engine oil. New oil is usually neutral and therefore will not rust the metal parts of the engine. Fill up the fuel tank with diesel to avoid fuel tank rust. If it is permitted, add preservatives to it. Start the engine once a month during the downtime and make the jaw crusher do short distance travel. Its goal is to make lubrication place to build a new oil film.

Finally is rust protection. Before jaw crusher storage, we should determine whether to choose torch-up or choose the method of spray paint to repair the machine according to the size of antirust paint falling off area. The best way for antirust of metal exposed parts is to smear butter.
