It is similar to hammer crusher that can crush materials with compressive strength ≤160MPa. The feed size of double roll crusher is medium, and the output size is adjustable.The roll crusher is equipped with safety protection device. When an accidental metal iron piece enters the crushing chamber, the protection device acts and the iron leakage equipment works normally. 8. The roll gap of the abrasive roll body of the roll crusher can be adjusted arbitrarily between 1mm and 20mm. After adjusting the roll gap.
The secondary roll is positively driven by heavy duty tyres. The tyre pressures are varied to suit the roll centre adjustment. Large springs of high quality steel counteract the crushing forces and allow release of uncrushable objects. A shear type safety device is incorporated to protect the machine against severe overload conditions.RollEase RE0051203 Safety Hold 3 Tension Device SKU RE0051203 Categories Chain Safety Devices , General Tags Chain Safety Device , RollEase , Safety Hold Tension Device ,.A roll crusher includes a crusher roll a support for rotatably and radially shiftably supporting the crusher roll Such a hydraulic cylinder acts as a safety device against excessive loads by permitting the piston rod to yield in case a predetermined pressure value is exceeded. In such a case, the clamping head remains in its immobilized.

It has simple structure, it consists of rack, actuator, crush roller, adjusting device and the spring safety device. Download Product Brochure.Double Roll Crushers are useful for intermediate size reduction of hard to medium hard materials, such as rock or ore, after processing with a jaw crusher, for final reduction with a pulverizer. They also bridge the gap between laboratory and continuous production or pilot plant crushing capacities. Especially recommended for assay offices.
Aug 11, 2017 The spring is safety device. When material with large pieces of debris or hard stuff can't be crush into the crushing cavity, the roller stress increases, and the moveable roller can move to the left and compress the spring through moveable bearing block. For the normal work of the roll crusher, we install the scraper device on each roller.Structure Characteristics of Roll Crusher. 1. Roll crusher is mainly composed of roller, roller support bearings, pressing and adjusting device, and driving unit. 2. The adjustment of discharging granularity a wedge or gasket adjustment device is set between the two rollers the top of wedge device is equipped with adjustment bolt when.Industry has been developing a range of devices which can help reduce the risk of serious entrapment crushing injuries. The International Powered Access Federation, IPAF has recently published a document outlining currently available devices to help protect against entrapment crushing injuries on mewps reference 2.
Feature China Juxin coal roll crusher has the wedge or gasket adjusting device, and they are mainly used to efficiently adjust the size of the final products.Motor is the key power for this series of used roll crusher, and in normal suitation, every double roll crusher is.Nov 08, 2014 When crushing the materials, materials from the inlet through the roller, will be crushed through rolling and the crushed materials will be discharged from the under frame. 4. For safety, the chain or belt of the driving part of teeth roll crusher and double roll crusher will be installed safety shields according to actual conditions.When performing maintenance inside large jaw crushers a specially designed platform may be inserted into the jaws to prevent movement and to provide a secure place to work from. Before lifting ensure the device is suitable for the job, and the load is securely attached with all personnel clear of the danger area.
The rolls crushers we sell are used in mining and parallel industries a double rolls crusher is a common type of equipment used as a primary crusher for sizing ore.Roll crushers are used for sizing sintered coals, soft and medium hard rocks, fertilizers and salts. The crushing material is fed on the top of the whole width of the rolls with the help of feeders.Double Roll Crusher working principle Double roll crusher consists of roll wheel, roll bearing, pressing device, adjusting device and driving device etc. Discharging size adjustment between two roller equipped with cuneate or gasket adjusting device, top of the wedge device capped with adjustment bolts.The bearing of active roller in the double roll crusher is supported by a set of hydraulic device. This device works as a safety device and adjustable device to adjust the discharge opening width, in addition, it is equipped with “compensating cylinder” for ensuring the axis of active roller and fixed roller is parallel with the movement of.
The toothed roll crusher can be divided into two big series, namely the double teeth roll crusher and four-toothed roll crusher. The double teeth roll crusher is a mechanical spring type(2PCM), which can equip coarse roll and medium roll according to the characteristics and requirements of crushing materials. The four-toothed roll crusher is actually consist of two double roll crushers.DOVE Tooth Roll Crushers have the highest crushing ratio in the industry, has no minimum requirements for moisture content of crushed material, no restrictions for sticking material, handle all type material efficiently. DOVE Tooth Roll Crushers are configured with intelligent cleaning device, to automatically remove the sticky material from the wall of the crusher.Aug 06, 2018 If you are thinking of taking your 4x4 over rough terrain you might want to consider using a Safety Devices roll cage to help protect you in case of a roll over.
