The inner and outside of the bearing are both double sealed, so the lubrication oil can be added in a long period. No matter whether it is toothed roller crusher, or double roller crusher, even or toothed double roller crusher, we all can supply. Beside the above roller crusher types, there is another roller crusher type: hydraulic roll crusher

The distance between the toothed rolls is adjusted by hydraulic and the bearing or the toothed rolls was centralized lubricated. Discharging size adjustment: between two roller equipped with cognate or gasket adjusting device, top of the wedge device capped with adjustment bolts. When adding gaskets the gap between wheels become large, when reducing gaskets the gap between wheels become small, so the discharging size becomes small

Introduction Double toothed roller crusher is developed on the basis of traditional roller crusher and combined with the design concept of machine, electricity and oil integrated. Working principle : The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls

Roll crushing of the sledging type have a crushing action unlike that of any of the machines thus far described. Moreover, the actions of the single and double-roll forms of this type are dissimilar, at least in the relative importance of impact and sledging action. Both types employ a combination of these two actions but in a reversed order of efficacy. As a sledging blow transfers a large part of its force by impact, it may seem anomalous to attempt to differentiate these two terms; nevertheless there is a convenient distinction between them as they apply to the action of crushing machines. Impact crushing is customarily taken to mean the breaking of a piece of material by a sharp blow, delivered with sufficient force to shatter the piece while it is in a free position, i.e., not restricted from moving away from the blow other than by its own inertia. Sledging, while the blow may be just as violent as the impact blow, is a stroke delivered against the material while it is prevented from moving away from the applied force by reason of being in contact with an opposing crushing surface, either fixed or moving

Crushing rolls might, logically, include roll crushers of the sledging type, the name, by popular usage, is restricted to the double-roll machine (with either smooth or corrugated shells) which crushes entirely by pressure between the surfaces of the roll faces. The sledging type of either single or double-roll arrangement is usually differentiated by such titles as “roll crusher” or “sledging rolls.” The only point of similarity in the actions of the crushing rolls and the gyratory and jaw types is that both do their crushing by pressure. As contrasted to the action of gyratory and jaw types, rolls have a continuous “one-bite” action; once a particle of material is firmly gripped, it is drawn down between the converging shell faces in one quick, continuous “squeeze,” until the discharge point is reached. Another point of difference is that the rolls do not rely upon gravity to work the material down through the crushing zone; the action is a forced, mechanical one. Still another difference between the types is that, in the crushing rolls, there is no “close-side” and “open-side” discharge setting; the distance between roll faces on a line between the two shaft centres establishes the discharge opening, which remains unchanged during normal operation. Mechanically, a pair of crushing rolls is a simple machine. Below are drawings that show all of the essential details of construction of a heavy-duty machine

A heavy and rigid cast-iron frame supports the two-roll assemblies, each of which comprises a shaft, a roll centre, and a shell of wear-resisting metal, such as high-carbon steel, or manganese steel. Each roll is independently driven by a flywheel type, flat-belt pulley, or V-belt sheave. One of the two pairs of bearings is arranged to slide horizontally on the side frames

These movable bearings are spring-loaded to provide a safety relief for excessive pressures, such as are caused by tramp iron, etc. They are drawn up against locating shims which establish the spacing between roll faces (discharge setting), and are held in that position by the springs, which are pre-set to the working pressure for which the particular machine is designed. This working pressure may vary from as low as 90 kilo per linear centimetre of roll face, for light-duty rolls, to as high as 5.3 tonne per centimetre of roll face for extra-heavy-duty rolls

So long as flat belts were the established driving medium, it was customary to equip the fixed roll with a large pulley, and the movable or spring roll with a smaller one generally one-half the diameter of the large one. The large pulley was designed to carry the full amount of power needed to drive both rolls, which of course relegated the smaller one to the status of an idling pulley; its sole purpose was to bring the spring roll up to speed, and to maintain that speed during idling periods

There was a logical purpose behind this arrangement. Because of the variables involved, it would be the exception, rather than the rule, if both roll faces ran at exactly the same speed under no-load conditions, and if this “slip” between faces continued when the rolls were loaded, wear on the shell faces would be greatly accelerated. The large-and- small pulley set-up permits the material to “gear” the shell faces together so that the speeds are the same, and any compensation that might be required in surface speeds is taken care of by belt slippage on the small pulley
