Buscar en toda la estación Equipo de trituración

Fine crusher is also called tertiary crusher, which adopts the principle of “stone hit stone” to crush materials. It upgrades the traditional three crushing stages to the two crushing stages.

The fine crusher is mainly suitable for grinding and processing in metallurgy, building materials, chemical, mining, railway, water conservancy and other industries. It is used before the ball mill to increase the production efficiency of the ball mill by 50%.

It is especially suitable for fine and medium crushing of materials with hardness below 9 such as quartz, feldspar, calcite, marble, ceramics, iron ore, copper ore, gangue, phosphate rock, granite, basalt, silicon carbide, corundum, insulation materials and other brittle materials.

La trituradora fina tiene varias ventajas:

1.High crushing efficiency. The use of grate plate, rigid hard extrusion crushing and solid rotor body greatly improve the crushing efficiency.

2.Good crushing effect. The fine crusher can arbitrarily control the discharging size of materials, so the required material size can reach more than 95% and ideal material size control and classification can be realized.

3.Small wear parts wearing. Compared with hammer crushers and impact crushers, it only wears the hammerhead, while the wheel core and hammer frame have no wear.

4.Simple installation. It is light in weight, diverse in installation (removable installation) and easy to operate.

5.Convenient maintenance. It only needs to lift the upper case and open the lowercase during maintenance. A person can complete a comprehensive inspection and maintenance of the whole machine within 20 minutes with a wrench.

6.Timely discharging. Three discharging channels are adopted to discharge qualified materials in time.

7.Adjustable discharging. The discharging granularity of the fine crusher can be adjusted, and the adjusting plate can be turned over at both ends.

Structure of the fine crusher

The fine crusher is mainly composed of the rotary part, guard plate and box part.

Some non-overlapping hammer carriers are arranged on the wheel core of the rotary part. The hammer head, whose width is larger than the hammer carrier and the wheel hub, is fixed on the hammer carrier. The wheel core is composed of several wheel hubs, which are fixed on the main shaft. The two ends of the main shaft are supported on the frame with rolling bearing seats.
