How Quad Roll Crushers Work. Quad Roll crushers are designed for larger feed sizes and high ratios of reduction at high capacities. The top stage of the Quad Roll crusher is essentially made up of a double roll crusher, which is designed with the appropriate diameter rolls and tooth configuration to readily grab the incoming feed material.
They feature a 6:1 reduction ratio in the primary stage, and a 4:1 reduction ratio in the secondary stage. This high capacity crusher simplifies the crushing process with a single machine and features an intermeshing tooth design, meaning that no timing gears are required. McLanahan offers the only Triple Roll Crusher in the industry.
A discrete element method (DEM) model of the crushing process of a toothed double-roll crusher (TDRC) is established using the bonded particle model. DEM results and …
Typically used as secondary or tertiary crushers, McLanahan Double Roll Crushers provide a 4:1 reduction ratio and can be used following other McLanahan equipment, such as Feeder-Breakers, Rotary Breakers, primary …
Double-Roll-Crushers are used for the crushing or medium-hard rock as well as for sticky and soft materials, i.e. clay, marl, limestone and similar raw materials.

Some standard roll crushers include single-roll, double-roll, and triple-roll crushers. They can also be designed with smooth or corrugated surfaces on the rollers to provide different levels of crushing action. ... Custom-Engineered Replaceable Roll Faces.

A discrete element method (DEM) model of the crushing process of a toothed double-roll crusher (TDRC) is established using the bonded particle model. DEM results and experimental data are compared quantitatively and a relatively good agreement is observed. The effects of rotation speed and structure of crushing rolls on the performance of TDRC are …
Single Roll Crushers. Single Roll Crushers are typically used as primary crushers that provide a crushing ratio of up to 6:1. They crush materials such as ROM coal, mine refuse, shale, slate, gypsum, bauxite, salt, soft shale, etc., while producing minimal fines.Designed with intermeshing roll teeth and a curved crushing plate, they are extremely effective in reducing slabby feeds.
DEM results and experimental data are compared quantitatively and a relatively good agreement is observed. The effects of rotation speed and structure of crushing rolls on the performance of TDRC are investigated numerically. ... The breakage behaviour of coals in the industrial sieving crusher and ordinary teeth roll crusher was compared based ...
ABSTRACT Comparison of breakage behavior of coals is conducted between the industrial sieving crusher (SC) and ordinary teeth roll crushers in different breakage flow sheets. Two types of coals, about 10 tons, are used for each comparison, and consumed energy and size distribution of products are analyzed. Due to differences in roll rotation rate and teeth …

However, Single Roll Crushers provide limited product sizing and are limited in throughput capacity. Double Roll Crushers feature two rotating roll shafts that crush material between the teeth and roll bodies. These types of Roll Crushers produce a cubical product with minimal fines generation, and can handle higher capacities.

Since for granulation processes the crusher operation has a decisive influence on the system stability, a reliable mathematical model to represent an industrial double-roll crusher of a urea granulation circuit is provided in this work. The crusher was described by the model given by Austin et al. [Austin L.G., Van Orden D.R., Perez J.W.
But, when rolls' speed exceeds 150 rpm, the crushing performance would not be significantly improved. A reasonable working gap and better nipping behaviour are obtained using the spiral-tooth-roll or the staggered-tooth-roll. The validated DEM model could be applied to gain a fundamental understanding of the crushing mechanisms of TDRC.
Progress in Roll-Crushing. BY C. Q. Payne, New York, N. Y. On the right, a Roll Crushers is shown in a sectional elevation of the A-C single-roll crusher while here below is a cutaway view of the machine, with hopper and part of the near side frame removed to show the crushing chamber. The moving elements of the machine consist of the roll, with its supporting shaft and …
The single-roll crusher has a tip speed of 400-450 ft/min while the 6- x 7-ft teethed roll crusher has a normal, no-load, surfaces speed of just under 3500 ft/min. It can be readily appreciated that this high velocity induces …

The single-roll crusher has a tip speed of 400-450 ft/min while the 6- x 7-ft teethed roll crusher has a normal, no-load, surfaces speed of just under 3500 ft/min. It can be readily appreciated that this high velocity induces an extremely violent crushing action, in conjunction with the 3- to 4-in. knobs which protrude from the roll surfaces.
Our Double Roll Crushers are heavy-duty – promising less wear and tear, less downtime and less disruption to your process. The robust design doesn't impede the capabilities of this roll crusher, which is capable of meeting the high capacities demanded by the mining industry.
Due to differences in roll rotation rate and teeth distribution on roll, breakage product of SC shows the lower yield of +50 mm particles and −6 mm fines, and the higher content of −50 + 6 mm progenies. SC also indicates the advantage of saving energy if compared with that of single tooth roll crusher and double teeth roll crusher (DTRC).
