Concrete introduction to main parts of single roll crusher

Hongxing Single Roll Crusher utilizes a cast iron gear and an alloy steel pinion gear. All Single Roll Crushers utilize the V-belt drive arrangement. Electric motor power is transmitted to a grooved and balanced flywheel pulley mounted on the countershaft. Vbelts provide power transmission between the electric motor and the countershaft. Here, we just conclude the structure of single roll crusher.


The base frames on all duty classes of our crushers are of heavy duty fabricated steel construction. All frames are substantially reinforced and braced for rugged crushing applications and years of service. The rigid construction prevents distortion of the frame during operation, resulting in maximum bearing, gear and shaft life.


The hopper areas on single roll crushers are of a large, unrestricted design spanning the full width of the crusher roll. This construction allows the machine to crush large feed lumps delivered into the hopper. The hopper is flanged at the top and equipped with drilled bolt holes for attachment of an auxiliary hopper or feed chute above the crusher. Renewable, abrasionresistant steel wear liners are furnished on the interior hopper side walls.

Crushing Plate

Crushing is carried out along the full width of the extra long, curved crushing plate, preventing material from jumping away from the roll. The fabricated steel crushing plate, either corrugated or smooth faced, extends from the top of the hopper. The crushing plate has easily replaceable wear liners that may be either slotted or smooth. The slotted design reduces slabs in the product when crushing slabby feeds. As the sketch above illustrates, the generous throat opening is designed to accept large slabby feeds. The crushing action is a combination of slow speed impact, splitting, accomplished by teeth piercing the feed lump as material is pulled through the tapered opening between crushing plate and roll. The curved crushing plate, with wide opening at the top and narrow opening at bottom, allows for maximum reduction ratio.

Shafts and Bearings

Roll shafts, countershafts and hinge shafts (located at the top of the crushing plate) are made of turned, ground and polished alloy steel of ample design and size to withstand crushing forces. Self aligning anti-friction roller bearings mounted in heavy duty steel housings are bolted to the frame to support the roll shaft and countershaft. Optional taconite seals can be provided for extremely dusty or wet material feeds.

Roll Design

Many types of rolls in various alloys of steel or chilled iron can be furnished with an extremely broad range of roll teeth configuration available. This assures the most efficient crushing of any specific material. With over 100 years of crushing experience, McLanahan Corporation has extensive data on the use of a great many styles of teeth on all types of materials. Correct recommendations of roll size and tooth selection is an important part of the service.

Gears, Pinions and Drives

Single roll crushers utilize machine cut teeth on the gear set between the roll shaft and countershaft. Gear teeth are designed with a wide face and large profile for maximum strength and power transmission. With the exception of the Cobra Single Roll Crusher, all gearing is cut from alloy steel.

Henan Hongxing Mining Machinery Co., Ltd has many years' of technological power and experience accumulation of manufacturing and management of spiral washer, crushing machine which have many advantages such as simple and reasonable structure, high independent impact crushing ability, super low operational cost and the most competitive price. These machines have the most competitive price and the most reliable quality so that they are the top choice for the high performance crushing equipment.
