Work roll crusher

Roller crusher working principle and structure:
1, the series of roll crusher mainly composed by the roller, roller support bearings, clamping and adjusting devices and drive components.
2, the expected size of the adjustment: between two rollers or pads with wedge adjustment device, the top wedge-shaped device with the adjustment bolt, when the adjustment bolt to pull up the wedge, the wedge top of the active roller away from the fixed wheel, two roller gap is larger,cone crusher the larger particle size, when the wedge down, the activities in the Spring-loaded roller under the action of two gap becomes smaller, the smaller particle size. Spacer device is through changes in the quantity or thickness shims to adjust the size of the particle size, increase the gasket when the roll gap when the two larger, as when two roller pads to reduce the gap becomes smaller, the smaller particle size .
3, the drive mechanism is composed of two electric motors through V-belt drive to the sheave on the drag roller, according to the relative direction rotation. In the broken material, the material from the inlet through the roller, the rolling and broken, broken after the product discharged from the chassis below.
4, for safety, should be based on actual driving part of the self-install the safety cover.
Roll crusher for use:
Roller crusher, reliable, easy maintenance, low running costs, adjustable discharge particle size. Can be classified according to the number of roller double roller crusher and four roller crusher can be widely used in cement,vacuum tumbler metallurgy, chemical industry, electric power and coal industries and the toughness of brittle materials processing.
Roller crusher for mineral, chemical, cement, construction materials and other industrial sectors, broken all kinds of medium hardness and crushing of ore and rock the following purposes.
Roller crusher maintenance protection
1) To strengthen the work to mine iron. Non-broken material (top solder material) fall between the damage on the roller crusher, resulting in a parking accident. So before the crusher unit should be installed in addition to iron.
2) The viscous material is easy to plug the break room, plug in the treatment failure should stop processing, can not be stabbed in the mining operation.
3) When dealing with large pieces of material is large, easy to pay attention to large pieces of ore from the crushing space out to prevent injury or damage to equipment.
4) roll crusher run a long time, due to the roll surface wear larger size too small will cause the product, then pay attention to adjust the port of discharge or equipment maintenance.
5) to strengthen the inspection of equipment, lubrication of the equipment on time and fuel to maintain the equipment well lubricated condition.
Henan Braun Machinery Co., Ltd. As a professional technology center-driven enterprise, mineral processing equipment for many years the company has been committed to breaking dried mining equipment, conveyor field of high-end development and progress. Through continuous R & D and innovation, the introduction of absorption, the formation of the development, design, manufacture, installation and integration services for a powerful professional for Wu.
Braun With advanced production testing equipment, strong technical strength, sophisticated technology combined with scientific management, stable and reliable product quality and good reputation of the company to provide protection. Since its establishment,positive displacement pump the products all over the country more than twenty provinces, municipalities, autonomous regions and exported to Southeast Asia, India and other places, well received by customers, the company known to be rapidly improved.
Roll crusher for primary crushing of materials is that it in some stone production line is also very widely used for cement, metallurgy, chemicals, electricity, coal, building materials, refractories and other industrial sectors broken, the higher hardness materials.
Normal under the roller crusher roller wear, the roller surface is not cylindrical, forming two big middle small concave profile. At this time a large lump of clay or mud pie is likely to wear through the notch, would not achieve the effect of broken, so the need for repair roller.
Roller repair used in two ways: place the cutting (grinding) process and in-situ repair method surfacing repair method.
(1) place the cutting (grinding) processing method
In situ cutting (grinding) processing method of operation is: in the crusher frame,stone crusher install a special knife, move the track should be parallel with the axis of the roller. Repair broken machines start with the manual feed sector (also can be conditionally automatic feed body) of the cutting roller. Application of this method should note the following:
① turret trajectory parallel with the axis of the roller, so after taper cutting, impact crushing effect.
② control the velocity of the roller. Roll surface speed should not exceed the allowable cutting speed cutting tools, or measures should be taken to slow down to avoid damage to the tool.
③ For the high hardness of the roller, the cutting can not be processed, then the method can be used for cutting grinding by grinding
(2) In situ welding method
Spot welding is carried out at the notch wear welding filler. This method is simple and practical, does not affect the production and welding parts of the hardness and wear resistance are relatively good, only drawback is that for good weldability roller (such as steel roller). Surfacing should note the following:
① Select the appropriate welding bar to the use of reactor 256 and reactor 266 is appropriate.
② should select the small diameter of the welding section, a small current welding specifications, welding stratified. This would reduce the thermal stress, to avoid serious distortion and cracks.
③ welding process, the model should always use a ruler to check for welding parts to ensure
Dimensions qualified.
④ Ground welding machine to directly take on the roller, do not ride on the shaft,automation solar machinery so as to avoid current flow through the bearing, resulting in sparks, so that the rolling bearing raceway surface of the body and burning.
In addition, it can be used after the demolition of repair method, that is, with all of roller shafts removed, restored by turning on the machine installation to use.
