subject: Improved Work Efficiency Of Fine Crusher [print this page] These measures have achieved certain effect, but the limitation is very big, it is difficult to popularize application, sometimes due to bad accident. At present our country mine fine works mostly use the spring type short head cone crusher or hydraulic cone crusher, sieving with self-centering vibrating screen, feeder for belt machine. These devices have been used for decades, backward technology, main show is in the following respects:
1 broken particle size of coarse, for general 20-30mm, individual plant selection of up to 40 mm.
The 2 crushing machine main parameters and design of crushing chamber crusher unreasonable, low utilization rate, energy consumption, large steel consumption.
3the low level of automation, no practical, reliable means of detection.
4matched auxiliary equipment stale, such as screen efficiency.
HONGXING machine according to the present situation of our country, improving fine cone crusher working efficiency problem, put forward the following feasible improvement measures:
1 improved crushing cavity design, selection of main parameters:
Crushing cavity shape, the crusher production capacity, power, consumption, the lining life, product size and shape plays an important role, so the crushing cavity technique called crusher technical core. While the crusher main parameters and eccentricity of eccentric bushing speed, were associated with the crushing cavity shapes.
Crushing cavity of improvement measures are mainly the following: (1) shorten the parallel region, ensure the ore in the parallel region crushing a premise, increase the crushing zone length. (2) reformulation cone crushing lines connected to the straight line and curve link, movable cone and cone joints staggered, reduce the blocking probability. (3) the shape of cavity consists of two meshing angle is changed into four nip angle area, improve the whole cavity utilization rate, avoid uneven wear. (4) will now eccentricity decreased about 15%. (5) the existing eccentric bushing speed raising 10%-13%, increasing yield.
2 to improve the vibrating sieve in the crushing system is an important link in the chain. At present our country mine crusher configuration of the vibrating screen mostly have some problems.
Improved measures are (1) to increase the screen length (2) increase in frequency (3) reduce the screen surface mounting angle (4) improved feeding way; (5) improved screen structure and materials.
The measures the actual situation may take one or a few.

Hongxing cone crusher through continuous development, can be highly effective, reliable, and economical material will be broken, as to meet the requirements of the final product. Italian machine PSG series represents the advanced crusher patent technology, high crushing efficiency, lower production cost, broken product quality better, can fully meet the various broken condition, even the most hard rock can also handle a situation with ease.
