History Of Rock Crushers

Dsmac sand production line mainly consists of vibrating feeder, jaw crusher, sand making machine, vibrating screen, sand washing machine, belt conveyor, electric control panel, etc, and capacity is 50-500t/h.

More than 110 years of engineering and customer service experience keep customers running to mclanahan tomeet their production goals.Mclanahan jaw crushers are proudly made in the usa and have imperial designs.With our grass roots design coupled with listening to customer needs for product enhancement over the years, mclanahan offers traditional hydraulic-shim adjustment jaw crushers as well ash-series jaw crushers that featurehydraulic discharge setting adjustment, adjust-on-the-fly chamber clearing in the event the site loses power (once power is restored) and hydraulic relief for overload events with auto-reset.

The space at the bottom of the v-aligned jaw plates is the output gap that dictates the size of the crushed product from the jaw crusher.The rock remains in the jaws until it is small enough to pass through the gap.

The lancaster products roll crusher is a compact unit built around a rigid cast frame.It is powered by a vfd gear drive unit.The high alloy steel shafts are driven by a heavy-duty chain operating in an enclosed oil bath.All parts coming in contact with the process material are replaceable and are made of wear-resistant alloys.Replaceable comb plates and cheek plates at the ends and sides of the housing prevent material from bypassing the rolls.

The rotor system of the hammer crushers is affected by factors such as rotor misalignment, bending of the shaft, looseness of the foundation, wear of the bearing, improper assembly, etc., and friction or even rubbing phenomenon with the bearing.Although the torque that the rotor is subjected to during operation of the equipment can be balanced, the rotational speed is greatly affected, the rotor system is also unstable, and the overall stability of the equipment is degraded.Main performance: first, the rotor system vibrates, and second, the rubbing has an impact on the rotor itself.The two overlap each other, resulting in more complex adverse reactions, such as phase reverse displacement and axial trajectory diffusion or disorder.In the design stage, in order to ensure the stability of the equipment, the gap between the rotating parts and the adjacent parts is relatively small, and it is easier to increase the probability of occurrence of rubbing.

Jaw crusher is generally used as the primary crusher in the crushing circuit and connects to the ore feeding machine.In the early years, common used plate feeder, but now, the vibrating feeder is more popular.Practice has proved that the vibrating feeder has advantages of low power consumption, strong transportation capacity, low failure rate and easy maintenance, which can fully meet the needs of both of large scale gold plant ore small scale processing plant.

Usually a jaw crusher is in an open circuit, but it can be used in a close circuit if the return load is not greater than 20% of the total feed and the raw feed is free of fines smaller than the closed side setting.
