Cement is a fine powder that is the principal strength-giving and property-controlling component of concrete. People often confuse cement with concrete. Concrete is a mixture of cement, aggregates, and water that hardens to form a building material used for everything from sidewalks, homes, roads, bridges, dams, and skyscrapers.

The special casting alloy used delivers a lightweight crusher with superior durability. Wider and deeper crushing area. The wedge arm penetrates concrete structures. The cylinder rod is protected by a rod cover. (Except for the TS-W250, TS-WB350, TS-WB500V, TS-W2200V models). Robust assembly. A high oil flow speed valve reduces cycle time.
The maximum pressure for the concrete crusher is 31 MPA or 4,496 PSI. Adjusting over this level of pressure is not recommended. Normal pressure is about 20-25 MPA or 2,900 - 3,265 PSI. However it depends on the machine as well. The best way to find out is to start at 15 MPA and increase the pressure until the power needed.

Crusher in cement industry application is very extensive. In order to meet the requirements of the production line, some manufacturers in the choice of the crusher is also very careful, you want to select a device to produce more in line with the requirements of the cement plant.
The less water you use to mix the concrete (somewhat dry but workable) the stronger the concrete mix. Accurate concrete mixing ratios can be achieved by measuring the dry materials using buckets or some other kind of measuring device. By measuring the mixing ratios you will have a consistent concrete mix throughout your entire project.
Raw material of various sizes are brought to the primary crusher by rear-dump haul units, or carried by a wheel front-end loader. Primary crushing reduces excavated rock to a more manageable size. There are different types of primary secondary and tertiary crushers including jaw crushers, gyratory crushers, impact crushers, and autogenous crushers.
