In most cases, both the Double Roll Crusher and DDC-Sizer will accomplish the desired results for many of the same applications however, there are differences between the two that offer operators greater choices to help meet the requirements of their particular crushing plant.
Free quoteThese differences include the installation, tramp iron protection, roll speeds and method of feeding, drive configurations, product size and, ultimately, cost.
In practically all cases, the V-belt driven Double Roll Crusher is rigidly mounted to the floor or structure with the feed chute and discharge chute firmly attached. The motor bases are also rigidly mounted to the floor independent of the crusher base mounting.
Conversely, the DDC-Sizer design incorporates steel wheels into the bottom of the base frame for mounting on rails. The unit can then be rolled out of the material flow, if necessary, to remove tramp material or to perform maintenance.
A flexible connection is utilized between the feed chute and the crusher feed opening to allow for unrestricted movement of the machine. Hydraulic cylinders are offered to raise and lower the wheel assemblies.
When an uncrushable item is encountered by a V-belt driven Double Roll Crusher, the movable roll will be forced to move laterally away from the stationary roll. The force exerted by the movable roll will overcome the preset spring tension of the automatic toggle mechanism.
This force causes the toggles to break open, allowing the movable roll to move away from the stationary roll long enough to pass the uncrushable object, then it immediately returns the movable roll to the original position. The crusher remains in constant operation throughout this process.
Tramp iron protection on the DDC-Sizer is provided by an underspeed sensor and fluid coupling on each drive. When an uncrushable object is encountered, the underspeed sensor observes a stall condition and shuts the drives down.
If this does not happen quickly enough, the torque load is increased and the fluid couplings will begin to slip. The fluid coupling slip relieves the stress on the components and therefore, protects the machinery.
There are no set rules for determining whether the secondary stage should consist of one single crusher, or of two or more machines operating in parallel. The decision must be made upon the merits of each problem. If the required receiving opening necessitates the selection of a crusher whose capacity equals or exceeds that of the primary crusher there is no object in going to a two-stage
Jan 10, 2019nbsp018332Crushed stone is the result of breaking down large rocks in a crushing machine. The most common ore used to make crushed stone includes granite, limestone, trap rock, basalt, dolomite and sandstone. Gravel is a natural product of weathering and erosion. It can be collected from river beds or harvested from the same quarries that produce crushed
Hammer crusher and cone crusher are both classic equipment in aggregate crushing and both widely used. This article briefly analyzes the difference between those two types of crushing machines in 6 factors, and we hope it can help you.
We have compared the pros and cons of many rock crushing equipment, and have received feedback from many users. So, we made this post to help you understand the difference between cone crusher and hammer crusher.
Before understanding the difference between those two major crushing machines, you first need to have a certain understanding of their basic crushing principle.
In simple terms, cone crusher uses lamination crushing, the mortar wall continuously moves toward the crushing wall, then squeezes the feed material between them, and crushes it to a suitable size.
While the hammer breaking adopts impact crushing, which is mainly broken by the impact, shearing, tearing, and mutual impact of materials.
By quickly review the working principle, now we can compare the difference between the two major crushers.
The cone crusher is suitable for the medium and fine crushing stage, and is often used in the second and third breaks in the production line.
While the hammer crushers can be used for coarse crushing and sometimes fine crushing. For example, some aggregate plants use hammer crushers for simply one stage crushing.
Indeed, the hammer crusher can break materials at one time without secondary crushing, but it is more common in small and medium-sized production lines and the requirements for the final particle size are not high.
Cone crushing is suitable for processing high-hardness stone materials, such as iron ore, basalt, granite, cobblestone, etc. It is the ideal equipment for crushing hard ore.
Difference Crusher Machine. Comparison and difference between jaw crusher and 1 application jaw crusher is commonly used in a broken will be a lot of material is suitable for the secondary crushing in such as cone crusher impact crusher machine such as feeding equipment if the feed is very big must use the jaw broken as the first stage crushing and impact crusher broken is generally not

Tertiary crusher, also known as high-efficiency fine crusher, and concrete crusher. This kind of concrete crusher machine for sale has a wide range of applications and its performance has reached the international leading level. HXJQ tertiary crusher is constantly improving in terms of performance, structure, design, materials, etc, promoting the development of the low-carbon economy.
Crusher machines are used for crushing of a wide variety of materials in the mining, iron and steel, and quarry industries. In quarry industry, they are used for crushing of rocks into granites for road-building and civil works. Crusher machines are equipped with a pair of crusher.
