The spring cone crusher has a perfect combination of
high-performance crushing chamber and high crushing frequency, which greatly
improves the crushing capacity. At the same time, it also absorbs the principle
of laminated crushing, which to a certain extent reduces needle like materials.
The spring safety system is an overload protection device that provides
"spring type" over iron release protection for foreign objects (iron
blocks). Under normal use, the equipment has a fault free operation rate of
over 95%.
Operational Principle:
The spring cone crusher uses a working surface between a movable
cone and a stationary cone to crush ore. The moving cone is supported on a
spherical bearing and fixed on a suspended vertical axis, which is placed
inside an eccentric sleeve, which in turn is placed on a thrust bearing. The
moving cone and the vertical shaft are driven by an eccentric shaft sleeve,
which is driven by a horizontal shaft and a belt pulley, and transmitted
through an bevel gear. The pulley is driven by an electric motor through a V-belt.
The lower part of the vertical axis is installed into the eccentric sleeve, and
when the eccentric sleeve rotates, a conical surface is drawn with the axis.
Therefore, when the moving cone approaches the stationary cone, the ore is
crushed. The casing consists of two parts, upper and lower, connected by bolts.
A strong spring is installed on the bolt to prevent damage to the crusher (such
as the spindle) when metal or other hard objects fall into the crushing
chamber. If a metal block or other hard object (nut, drill head, etc.) enters
the crushing chamber together with the ore, the stationary cone is lifted and
the ore discharge port increases to discharge it.

At present, the intelligent lighting products on the market mainly achieve the intelligent effect by using the control function of the driving power source, and the technology itself is not difficult. At the same time, the demand for LED intelligent lighting in the Chinese market is not high. According to relevant research data, the penetration rate of intelligent LED lighting in mainland China is less than 2, and the application of the products is mainly reflected in dimmable LED landscape lights, color-adjustable LED street lights and their monitoring.
At present, the research on intelligent lighting by mainland enterprises mainly stays in LED dimmable color lighting products, and there are still few manufacturers that actually carry out systematic LED intelligent lighting. Zhang Longxin admits that the current understanding of the concept of intelligence in mainland LED lighting companies is not thorough. Mainland enterprises are blindly pursuing intelligence and focusing on immediate interests. The international understanding of intelligence is mainly from the coordination of people and the environment. As a starting point.
Energy saving and environmental protection, but the market is always no shortage of followers. In this regard, some people in the industry have their own views: on the one hand, because intelligence is an inevitable trend of market development, on the other hand, the so-called intelligent lighting products on the market are not costly, and the profits are not low.
According to the survey data, the cost of an LED driver with intelligent control function does not exceed 5 yuan. The ex-factory price of lighting fixtures with such power supply is 20-30 higher than that of ordinary lamps. The industry has calculated an account, only The above intelligent configuration can increase the gross profit of the lamp by at least 20, and some high-end dimmable products can even reach more than 30.
At present, the enterprises that layout intelligent lighting in mainland China are mainly emerging LED lighting companies. Shenzhen Juju Industrial Co., Ltd., which is mainly engaged in the Japanese market, has sold nearly 30% of its total sales in 2011. Xiao Ling, general manager of the company, said that intelligent lighting (automatic induction, dimming and color adjustment) is now more popular in the Japanese market as a high-end product.
In terms of R&D investment, these companies also spare no effort. Among them, Qinshang Optoelectronics invested a total of 7.65 million projects in LED intelligent street lamps and power key technologies in 2011, accounting for 51.69 of all R&D investment. According to the plan, in 2012, the company will also invest 11.3 million yuan in new research and development. Among the 15 LED lighting companies with revenues of over 100 million, the related intelligent R&D expenses of 12 companies accounted for more than 30% of the total R&D expenses.
Considering the factors such as cost and sales volume, traditional lighting companies have not mentioned the intelligent lighting. The words of intelligent lighting have not been found on the public information of listed companies such as NVC Lighting and Foshan Lighting. A traditional lighting manufacturer said that the main reason is that intelligent LED lighting is still in the stage of personalization.
