4) Save 15~30% energy 

 

Application of PEX250×1000 Jaw crusher

This series of jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. They are widely applied to crush high hardness, mid hardness and soft rocks and ores such as slags, construction materials, marble, etc. The pressure resistance strength is under 200Mpa, that is, suitable for primary crush.They can be used in mining, metallurgical industry, construction, road and railwaybuilding, conversancy, chemistry, etc.

 

Working Principle of PEX250×1000 Jaw crusher

This series jaw crusher adopts electric motor as the power, and the eccentric shaft is revolved by an electric motor through v-belts. It causes the swing jaw to follow the pre concerted path and crush the in-fed materials, and then the materials will be crushed in the crushing chamber which is composed of the stationary jaw plate, swing jaw plate and the liner plate. Finally the finished materials are discharged from the lower part of machine.

Please carefully examine the fasteners, especially the lubrication components and bolts before starting the machine. Enough oil is needed on each lubrication component. Fasten the loose bolts, clean the crushing cavity, and then start the machine. Insufficient load or over load is not allowed. Moving jaw plate, fixed jaw plate, side guard plate and roof plate are wearing parts, and much attention should be paid to them.

Q:What are the requirements of the temperature of the crusher when it is working normally?
The jaw crusher bearing off the oil or oil injected too much; plug hole, oil and not fly; counterweight sheave position deviation, rack beat; abdapter axial moving; bearing wear or damage of the holder, the bearing temperature can cause the jaw crusher is too high. Aiming at the above problems, summarizes the corresponding methods: according to the instructions provided on time, quantitative gas; clean up oil holes and grooves blockage; adjusting the flywheel counterbalance position; removing rack bearing cover, lock bushing and remove the flywheel or Geneva, the replacement of the locking sleeve; replacement bearing; replace the end cover and the sealing sleeve, bearing cover or loosen the frame bearing seat at one end of the heating fuse, and embedded with the cover frame bearing seat is pressed into the groove, and then set on the bearing cover, remove block cover rotation. Jaw crusher, users need regular equipment overhaul, maintenance, in order to ensure the stable operation of equipment.
Q:How about double breakers crushing pebbles? Has anyone ever used them?
Constantly update their thinking, explore innovation, and strive to develop new, better, and more able to keep pace with the times. The performance of the product is superior to that of the old crusher in the aspects of output, spare parts life, operation rate and maintenance management cost.
Q:Which brand is better for compound crusher?
A composite type of our factory to buy from the factory in the East long heavy crusher to now has not changed
Q:How to choose the crushing method of ore
According to the provisions of the original release in 1980 the Ministry of coal industry technical guidance document, the evaluation method of process effect of crushing equipment in coal preparation plant (MT / Z2 - 1979), should be used as the main index of fine crushing efficiency, increment as auxiliary indexes, comprehensive evaluation of the effect of crusher.Crushing efficiency; press calculation:Granular incremental push down calculation:The "fine grain" here is aimed at the size of the broken product:When the particle size requirement is greater than and equal to 50 mm of coarse crushing, "fine grain" means 0~13 mm;Nesting granularity requires less than 50 mm of medium crushing and fine crushing, and "fine grain" means 0 ~ 0.5 mm.
Q:What is the function of the toothed plate of the crusher?
The toothed plate of a crusher is divided into a fixed toothed plate and a movable toothed plate, and a crusher toothed plate is a tool for crushing materials, and is the main component of the crusher. For example, jaw crusher operation state, the movable jaw attached to a movable jaw plate made of compound pendulum movement, forming an angle extrusion stone and fixed jaw plate. Therefore, the tooth plate is also broken parts in the crusher which is easy to damage (short: wearing parts).
Q:What are the common crushers?
Mainly depends on what kind of crusher, generally have jaw plate, hammer head, lining board, etc.
Q:What are some common crushing methods for crusher?
Crushing machine according to different methods of application, crushing of materials, extrusion, bending, impact, shear and grinding and other crushing methods.
Q:What is the working principle of a crusher?
According to the principle of crushing, heavy mining machinery machinery have often broken jaw crusher, impact crusher, vertical impact crusher, hydraulic cone crusher, hammer crusher, hammer crusher, roller crusher, composite crusher, cone crusher, crusher, double stage gyratory crusher, mobile crusher etc..
Q:Forging hammer for crusher? What material is better?
Hammer crusher, accurate definition should be a hammer crusher, hammer crusher is one of the core parts, arranged in the hammer shaft crusher rotor, hammer crusher in high speed direct strike materials and eventually break into the appropriate size of materials.The crusher hammers on the market can be divided into two kinds according to the manufacturing process: Casting and forging, but their degree of wear is different.Because of the broken material, good abrasion resistance and head to handle and need enough toughness, usually with alloy steel, high manganese steel, cast steel high forming a forging or casting method with chromium cast iron bimetal composite material, with the corresponding heat treatment process is more economic point.Crusher hammer can be divided into kinds according to the material: high manganese steel hammer, double metal hammer, composite hammer, medium chromium alloy hammer, carbide hammer and so on.What kind of hammer is the most wearable on the market now? The main factor is the content of silicon dioxide. The technology in modern industry shows that the cemented carbide hammer has good wear resistance.
Q:Structure of ring hammer crusher
It is suitable for crushing brittle, medium and hard materials with little water content. In building materials, metallurgy, chemical industry and thermal power generation industry, it is mainly used for crushing coal, coal gangue, Sha Yan, shale, limestone, gypsum and other minerals. This series of crusher has the characteristics of smooth running, reliable, long service life, compact structure, less dust, low noise, light weight, convenient maintenance, low power consumption, strong ability to discharge super hard material.Ring hammer crusher PCH ring hammer crusher type specification
