RockSledger jaw crushers feature massive, stress relieved, single plate walls with deep and substantial external side stiffeners and a high quality forged steel eccentric shaft. The shaft is fully machined and has a ground finish on all bearing contact surfaces to increase resistance to shock loadings resulting in longer machine life.
The general rule for manual grease is to apply ¼lb per bearing every eight hours of operation. It is best to grease the bearings at the end of the shift while they are warm to evenly displace the grease to the bearing rollers. Over time, a wet bead or line of grease should be seen between the labyrinth seal and the bearing housing.

C Series™ jaw crusher basic concepts The jaw crusher is a compression type crusher. Feed material is crushed between fixed and movable jaw dies. Large particles are crushed in a single layer, referred to as single-layer crushing. Smaller particles are crushed rock on rock, referred to as multi-layer crushing. C Series™ jaw crusher basic ...
hello there. I am civil engineer currently working on crushing quarry. I am getting a problem about my double toggle jaw crusher. the flywheel, toggles and everything is currently working well, but the problem is that its not crushing properly. in addition there are rubber or fiber parts at the front and rear of each toggle plate, so it destroyed those rubbers at the …
Jaw design for your application Jaw crusher wear parts are designed for processing all rock types in surface and underground operations. Our offering consists of jaw plates such as different one-piece jaws and two-piece jaws as well as cheek plates.
The sliding bearing is first ground and placed in the frame bearing housing to measure the deviation of the slope and the coaxiality. Then apply oil to the bearing and journal surfaces and place the movable jaw in the …
For large jaw crushers, the sliding bearing temperature usually does not exceed 60°C to prevent the melting of alloy bushes and cause bush burning accidents. When the bearing temperature is found to be very high, effective measures should be taken to reduce the bearing temperature in time (such as forced ventilation or water cooling, etc.). 5.
trial jaw crushers was analyzed using the proposed equation in combination with that of Bond (1961) for calculating the energy requirement in size reduction. The equation for capacity The volumeof material (V) that passes through the crusher bottom opening per stroke is given by: If the machine is run at low speeds, the movement of the
Crushing ore to size takes a tough machine. And equally tough bearings and seals that can cope with the harsh operating conditions and keep the crusher up and running reliably. The right solutions can help ensure crusher bearings deliver the necessary performance while avoiding premature failure.
Although jaw crushers are extensively used for a variety of materials, their operational characteristics are not well understood. This lack of understanding makes selection of …
Here, We summarizes the common failure and treatment of the jaw crusher. 1. The main engine stops suddenly Failure cause: blocking of discharge opening, resulting …
A jaw crusher is recommended for tough, abrasive, high compressive strength materials. Special machines have been designed for ores having compressive strength as high as 80,000 lbs per sq in. All-steel sectionalized frame. End members are box section. Deep side members of welded steel plate.
Here, We summarizes the common failure and treatment of the jaw crusher. 1. The main engine stops suddenly Failure cause: blocking of discharge opening, resulting in blocking of stock bin; the triangular rubber belt that drives the groove wheel is too loose, causing the rubber belt to slip;
On the overhead eccentric style Jaw Crusher, the moving swing jaw is suspended on the eccentric shaft with heavy-duty double roll spherical roller bearings. The swing jaw …
Jaw crusher Common problems you would face when operating a jaw crusher. 1 Premature bearing failures. That's because you haven't make a regular cleaning in the oil chamber which is full of dust and fines. If bearing cannot get efficient lubrication, it is liable to got broken, and interupt the production at least 1 hour.
In the Dodge-type crusher, the movable jaw is pivoted at the bottom of the V. and thus it has a variable feed and a fixed discharge opening. This design also implies that the greatest amount of motion is at the top of the jaws. This type of crusher yields little oversize product and a great many fines. It also tends to "choke".

1 The bearing is lack of the oil or the oil is injected too much. 2 The oil hole is blocked so the oil can not be added. 3 The position of the weight wedge of the flywheel is offset and the frame is beating. 4 The bushing occurs axial movement. 5 Bearing is worn or cage is damaged, etc.
The 48 by 42-inch jaw crusher and smaller sizes are force-fed by an automatic high-pressure lubricator to the swing jaw, pitman, and main bearings as illustrated in Figure 1. A motor-driven pump forces the lubricant through pressure buildup cylinders and out to distributors which dispense a precise amount to each of the points on the bearings.
A jaw crusher includes a crushing chamber between a fixed jaw and a swing jaw. The jaw crusher also includes an eccentric drive which supports the first end of the swing jaw. The second end of the swing jaw is supported on a rocker plate. The counter-bearing of the rocker plate is arranged as a cross-member and is supported on a hydraulic overload …
