Lancaster Products Roll Crusher rolls rotate toward each other, confining all crushing to the area where the teeth mesh. Both rolls are timed to rotate at the same speed to maintain a true crushing action. All material entering the crusher pass through the mounted twin shaft rolls.
ROLL CRUSHER Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1.
Roll Crushers. Roll Crushers are designed to handle the primary, secondary and tertiary stage crushing of friable materials such as coal, salt, clay, bauxite, limestone and other minerals of similar characteristics in the mining, power …
Double Roll Crusher. Double roll crusher is a relatively old crushing equipment. After numerous upgrades and transformations, the manufacturing process is more mature. The equipment has a simple structure and less over-crushing. The tooth shape, size and arrangement on the roller surface can be changed according to the nature of the material.
Roll crushing surfaces operate at a fixed distance apart, as opposed to the continually changing distances in a jaw or cone crusher. This creates a more consistent product size. Roll crushers are low in profile and relatively easy to install. They can be fed with a minimum of headroom, or even choke fed.
A middle-sized crushing machine to compress and crush materials fed from the upper opening onto two rolls being horizontally installed and rotating inward. It is a machine which has less metal contaminant. Easy adjustment of roller gap
Roll crusher, also called roller crusher machine, is a kind of traditional crushing mill, mainly used for the middle and fine processing of raw material applied in cement plant, chemical industry, building materials industry, etc.It is usually classified into three types: single-roll crusher, double-roll crusher and four-roll crusher.
Mode of Operation. Comminution of the feed material between the two rolls (fixed and moveable) by mechanical pressure up to 200 to 400 kN, hydraulically induced. Opening of the gap between the crushing rolls in case of overload (e.g. caused by an unbreakable foreign object) within milliseconds to let that piece pass thus avoiding a shut-down.
The double smooth roll crusher can be used for finely crushing various high and medium hardness ores and rocks in the industries. The gear roller type is suitable for medium and fine crushing with feed particle size is less than 150mm and the finished product particle size is …
Roll crusher, as one of the most economical and practical crushers, is designed to handle the first and second crushing of friable minerals and stones such as coal, clay, coal gangue, limestone, slag, cement clinkers, and shale, etc. With many improvements and upgrades, the FTM roll crusher has reached the international level and ranked among ...
The capacity of the single-roll crushers is a function of the roll gap, the roll length, and the speed, and ranges from about 30 tons/h (27 metric tons/h) for a 24-inch-long (61 cm) roll crushing to ¾ inch (2 cm), up to approximately 1500 tons/h (1360 metric tons/h) for an 84-inch-long (213 cm) roll crushing to pass 10 inches (25 cm).
