Any parts not selected by the robot are recirculated back into the main hopper to be presented again. Like bowl feeders these systems require minimal human handling but can have a sizable footprint. It is plain to see that many options exist for how a part will be loaded into an automated machine with each of these methods having its pros and cons.
Jun 01, 2019nbsp018332What is jaw crusher for Jaw Crusher is a kind of mining equipment used for primary and secondary crushing. It is widely used in medium-sized crushing of various ores and bulk materials in mining, smelting, building materials, highway, railway, water conservancy, and chemical industries.
Jaw crusher is a kind of rock crusher equipment. This jaw crusher handbook that we hope can help you to learn more about the stone crusher. ... Adjusting the relative position between the fixed jaw plate and the movable jaw plate to ensure that the tooth top is fixed and pressed against the tooth root to prevent displacement. 5 Raise the ...
Jaw crushers are widely used in mining smelting, building materials, roads, railways, water conservancy, and chemical industries. There will be a strong vibration in the work, because of the large hardness of crusher materials. Therefore, the work of the installation of a jaw crusher is very important. This article describes the installation points and matters need the attention of 6 jaw crusher parts.
The frame of the jaw crusher needs to install on the foundation before assembly crusher. Then install the other parts in sequence.
The installation of the crusher frame should be pad something that reduces vibration between the frame and concrete. Such as hardwood, rubber, etc. The horizontal and vertical levelness of the frame-mounted on a foundation or on a wooden base shall be in accordance with the installation requirements of the equipment. When installing the frame, the horizontal and vertical levelness of the frame on the foundation shall be less than 0.2 mm.
Before assembling the shaft and bearing, it is necessary to make good lapping of the sliding bearing. Then put it into the sliding bearing housing. Testing its placement of the level and coaxially through the gradient machine. If the measurement results meet the requirements, then install the eccentric shaft on the bearing. And check the fit between the shaft and the bearing via the red powder which applied to the journal.
Because it needs to use the principle of thermal expansion and cold contraction during install the bearing. So the heating process must be strictly controlled. Selects the suitable temperature to heat for should be selected for different specifications and sizes of bearings. The bearings of jaw crushers are large size bearing. It will cause the assembly quality to decline if uneven heating. Therefore, we choose to reheat the other side by turning the bearing direction 180 to ensure the even heating of the bearing.
It is required to strike the bearing diagonally during assembly. It makes sure that the bearings balance into the eccentric shaft. When the eccentric shaft enters the movable jaw, we need to strike the jaw with a hammer. The eccentric shaft is loaded into the moving jaw by using the interaction force without damaging the bearing on the eccentric shaft.
The grease is injected into the movable jaw by a butter oil injector. The Grease added into the bearing is about 50 of its space capacity and is changed every 3-6 months. When the oil change, the raceway of the roller bearing should be cleaned with clean gasoline or kerosene. So that the bearing lubrication is fully uniform, bearing in heavy load, the high temperature under the role of a good lubrication. It extends the service life of the broken bearing.
Powerful jaw crusher has a feed opening of 48-in. x 32-in. and is equipped with an extra long articulated crusher jaw To ensure the best possible material flow, the continuous feed system CFS ...
The movable jaw of the jaw crusher is assembled by preassembled movable jaw parts. First,Assemble the movable jaw parts accordingly. The movable jaw, movable jaw shaft, movable tooth plate, and bracket pad are assembled on the ground. Then use the crane lifts the assembled parts into the rack of the crusher.
For the sliding bearing which needs to install it. Then put into the housing, measuring its inclination and coaxiality of the deviation. If it within the allowable range, the bearing and journal surfaces are coated with lubricating oil. The movable jaw is placed in the bearing, and the coaxiality and inclination of the assembly of the sliding bearing are tested. The inclination is guaranteed to be 0.2 mm, and the coaxiality is less than 0.06 mm. The installation of the movable jaw is completed.
The TST jaw crushers are engineered for trouble-free operation, characterized by safe and easy serviceability. The most modern analysis techniques and features available to date ensure a strong and reliable crusher design. The TST is equipped with an efficient crushing motion, modular frame and a simple, low maintenance design to handle ...
To ensure optimum performance, the jaw crusher needs to have a good feed level and a homogeneous feed. Our jaw crushers are of the single-toggle type and feature a deep, symmetrical crushing chamber, a large feed opening for its size, and an ideal nip angle that offers smooth material flow and high reduction efficiency. Jaw crushers are ...

Nordbergreg C120trade jaw crusher is generally used as primary crusher, as the first step of size reduction. It prepares the feed for the secondary crusher in a crushing and screening process. However, due to its versatility, Nordbergreg C120trade jaw crusher can be utilized in later stages of the crushing process as well, depending on the application and processed material.
Nordbergreg C120trade jaw crusher is the result of extensive product development and research. Cavity, kinematics and operating parameters have been defined and optimized to ensure the outstanding performance for which Nordbergreg C Seriestrade jaw crushers are known and valued. Crusher height gives the steepest possible cavity cross-section, and the nip angle high up in the cavity, together with an aggressive well-aligned stroke at the bottom, ensure high throughput capacity and reduction.
Nordbergreg C120trade jaw crusher has a range of bolt-on options, including an on-board motor base and guarding for the flywheel and drives, made from specially developed composite materials. The unit is simple to install as a single crusher or as a complete module in a new or existing plant. Nordbergreg C120trade jaw crusher is mounted without bolts between the crusher and its structure by using mounting pads, which absorbs the dynamic forces and reduce the dynamic loads transmitted to the structure underneath.
For save operation and maintenance, Nordbergreg C120trade jaw crusher has a limited number of easily accessible service points. The lifting tools for items such as jaw dies, cheek plates, and the toggle plate are supplied with the crusher to simplify maintenance, making it safer for the crusher operators and service crew.
Active Setting Control ASC system is an optional accessory for Nordbergreg C120trade jaw crusher. This advanced system automatically adjusts the crusher settings in a way that uncrushable objects exit the cavity before causing blockages or inefficiencies. Active Setting Control enables continuous crushing and protects Nordbergreg C120trade from extreme overloads.
