Amid the ore crushing machines, roll crusher would be the oldest. Its mechanical overall performance isn't so great as many other crushers, to ensure it's been replaced by cone crusher in lots of metal mines. However, because of its simple structure, it is still broadly made use of in cement and silicate business. Also, in small-sized mines or when processing valuable ores, roll crusher is usually used. In this paper, SBM authorities will introduce the main classification procedures of roll crusher.

(one) Roll crusher can be divided into single roll crusher and double-roll crusher in accordance to your variety of the rolls.
Single roll crusher: It truly is composed of a rotating roll along with a jaw plate, to ensure it could possibly also be identified as jaw roll crusher. Ores are crushed involving the roll along with the jaw plate, and lastly discharged from your discharging mouth. This crusher is often appropriate for your coarse crushing of medium tricky sticky ores.
Double-roll crusher: It utilizes two cylinder-shaped rollers because the key operating device. Through the working system, the 2 rollers rotate during the opposite route. As a result of the friction amongst the supplies along with the rolls, the materials are going to be drawn to the crushing chamber formed through the two rollers and be crushed, and beneath the gravity, the crushed elements will be discharged through the gap in between the two rolls. This gap will identify the maximum granularity on the last solutions. This roll crusher is usually utilised for that medium and fine crushing of elements.

(two) Roll crusher can be divided into plain roll crusher and non-plain roll crusher according on the surface from the roll.
Plain roll crusher: The crushing force of this crusher mainly comes from squashing and grinding. This crusher is mostly used for the medium and fine crushing of medium difficult components.
Non-plain roll crusher can be divided into toothed roll crusher and chute roll crusher.
Toothed roll crusher has the characteristics of small size, major crushing ratio, lower noise, basic framework, handy upkeep, large productivity, even granularity on the crushed products, minimal over-crushing ratio, versatile overload protection and safety and reliable operation, to ensure it is appropriate for crushing raw coal in large-sized coal mines and coal dressing plants in coal, metallurgy, mine, chemistry and setting up resources.
