How to Choose A Cost-effective Jaw Crusher

Jaw crusher, commonly known as smashed, is also known as "Tiger's mouth" and is the main equipment in the stone production line. It is generally used for coarse and medium-hard crushing of hard or medium-hard stone, and has been widely used in the fields of mining smelting, building materials, highways, railways, water conservancy and chemical industry.

Jaw crusher with high quality and low price is almost theequipment that all users pursue. In daily production, the quality of smashingis directly related to production efficiency, production capacity, finishedproduct effect, corporate cost, and economic benefits. The following pointsmust be related to the quality, production efficiency, and economic benefits ofsmashing.

First, rack design - overall casting vs split assembly

Due to the limitation of the casting technology, the entirecasting frame will form a large number of tiny pores or inclusions in thecasting process, thus reducing the overall performance of the frame. Incontrast, split-assembly jaw crushers are lighter, stronger, and more durable.

Second, seesaw design - overall vs three-stage

The large smashing uses three-segment combination sampan boards.It is more convenient to combine, install, and dismantle. The most important isthat the middle piece is the smallest and the two ends are the same size. Ifthe bottom of the seesaw is worn more seriously, you can swap the position withthe top jaw and continue to use it. This saves costs.

Third, the bearing seat fixation - welding vs bolt

Some smashed broken bearing seats are welded on the frame, andsome bearing seats adopt integral cast steel structure and are bolted to theframe to ensure complete cooperation with the crushing frame and greatlyincrease the radial of the bearing housing strength. Different manufacturingprocesses make the service life of the two different.

In addition, some heavy-duty shields are installed on the bearinghousing to avoid accidental damage to the bearing housing.

Fourth, adjust the way - hydraulic wedge adjustment vs gasketadjustment

Hydraulic wedge adjustment can achieve stepless adjustment,convenient adjustment, save time, no need to stop, more simple, convenient,fast, advanced technology, high efficiency, of course, its price is also high.

Fifth, broken cavity shape - half V shape vs symmetrical V shape

V-shaped cavity structure makes the actual feed port widthconsistent with the nominal feed port width, and easier to discharge,relatively easy to block material, not easy to feed, deeper crushing cavity, nodead zone, crushing efficiency high.

Sixth, lubrication method - manual lubrication vs centralizedhydraulic lubrication

Some of the old jaw crushers were manually lubricated. Theoperator used oil or oil guns to lubricate the oil holes, nipples, and oilcups. This method is time-consuming and laborious. In contrast, centralizedhydraulic lubrication has taken a big step forward in terms of operability andtechnology.

Seventh, shield shape - ordinary shield vs. tooth shield

Because the shield and the material contact more, in order toextend the service life, the general choice of wear-resistant high-manganesesteel material. Compared to ordinary guards, toothed guards increase theeffective length of the jaws and increase output.

In addition to the above, the production materials, processingtechnology, and processing technology level of the broken parts also affect thequality of the equipment and the production efficiency. "Good goods arenot cheap, cheap goods are not good," there is a certain truth, but it isnot entirely correct, ZK CORP in this warm reminder, in the purchase ofequipment can not be overly valued, to understand the quality, a number ofcomparisons, choose manufacturers of regular products, so as not to affect thesubsequent normal production.
