Ultrafine Mill
Heavy-duty steel grating is a kind of open grid assembly composed of bearing bars and cross bars. The bearing bar is the main load-bearing component which is available in various shapes such as flat, I-shape, and Serrated.
The cross bars are connected to bearing bars by welding, pressure locked, or riveting methods. The bearing bar and cross bars are generally made of plain steel, structural steel, or other alloys.
On the surface, heavy-duty steel grating has many types of finish treatments, such as black paint, hot-dipped galvanized, and so on.

Performance
HST Single-cylinder Hydraulic Cone Crusher achieves higher production efficiency and better product quality by matching suitable crushing cavity, eccentric distance and movement parameters. Combined with optimized strength and high-quality components, HST Hydraulic Cone Crusher has bigger holding capacity and crushing ratio as well as stronger throughput capability.
HST Hydraulic Cone Crusher has a simple structure. Almost all checks and maintenances can be done by only taking down the upper rack. The structure can not only make maintenances and checks get easier, but also save maintenance costs a lot. Besides, HST Single-cylinder Hydraulic Cone Crusher is compact on its structure, occupying small floor area, which further cuts expenditures on the foundation building.
There are tens of lines of numerical controlling machine tools. Operations such as steel plates’ cutting, bending, planing, milling and paint spraying are all controlled numerically. The machining precision is high, especially for the core parts.
The fully automatic control system equipped on the HST Cone Crusher can provide manual control, constant discharge opening control, constant power control and many other operation modes for users to select. It can continuously monitor the internal actual load of the crusher to optimize the use ratio of the crusher and allow it to play its best performance at all times.
HST Hydraulic Cone Crusher has several kinds of standard crushing cavities which can fully meet the secondary, tertiary and even quaternary crushing needs after primary coarse crushing.
Rolls, whose businesses cover production and sales, takes responsibility for every machine produced by ourselves. We can offer customers technical services about products and original spare parts to ensure the worry-free operation.
Working Principle
When a HST Single Cylinder Hydraulic Cone Crusher works, driven by the motor, the transmission shaft rotates under the action of belt pulley and triangular belt. Next, the transmission shaft drives the eccentric sleeve to make it rotate around the axis. Meanwhile, the eccentric sleeve forces the movable cone to do pendular movement. This movement makes the movable cone and fixed cone sometimes close to, sometimes far away from the rolling wall. Materials are continuously shocked, squeezed and crushed in the crushing cavity between the crushing wall and the rolling wall. Finally, materials are discharged out of the machine when their fineness reaches the discharging standard.
