The Sand Making Machine industry supplies all kinds of machines as tools to help industries and customers exploit and handle minerals and materials. These machines include mining machines and beneficiation equipment such as crusher, grinder, screener and separator etc. Though the mining machinery industry has played a key role in the national economy, there are also problems occurring for a long time. So what are these problems in front of us? The mobile crushers made by our company are quite popular in the domestic market of industrial machines. They are considered to be the core support for the subway construction project. The mobile crusher station can transform the construction wastes to new products with much advantages of energy saving, low cost and environment protection. The local governments start to gradually encourage the machinery manufacturers to apply new regeneration bricks made from the construction wastes.
First, most Raymond Mill machinery enterprises do not have strong enough capacity to compare with the foreign ones. They are poor at doing research and development on the mining technology, product innovation, service upgrading and business administration. Many of them dare not spend too much time, labor and capital in developing the mining industry. A lot of core devices are urgently needed in the domestic market, but the Chinese enterprises can't create and manufacture them. Even when we make some necessary machines, the quality and performance won't satisfy customers.
Second, we have too many problems with the variety, technology, quality and service of the whole industry, which leads the mining machinery manufacturing industry to make little use of the mines all over the country. Though there are countless mining machines on sale in the market, few of them are made by the domestic companies and most advanced ones are exported from the foreign countries. Compared with the world class equipment, the domestic one still has a long way to go. It's said that the Chinese mining industry needs 15-20 years to catch up with the international development level. When disassemble parts with precision, the surface of these parts should be taken special care to protect to prevent damage and dirt. When disassemble parts with bearing surfaces or process components on their surfaces, make the parts to lay on the floor planks, prevent directly contact with the ground. When assemble or removing parts, directly knocking them with a hammer is not allowed, a copper rod pad or the appropriate pads are required. When one bearing is damaged, the two bearings should be replaced together. When replacing the ring, oil it and roll into the groove, stretching is not allowed.
When installing new screens, firm and tighten evenly the hook of the screen and angle iron or steel on the sieves of the box bearing cage. All parts must be cleaned and oiled before assembly. The lifting equipment for hoisting the parts should have enough lifting capacity. The high frequency vibrating screen produced by Our Machinery has different principles from general screening equipment. Due to working in a state of high frequency, the surface tension of pulp is damaged, and the oscillates of fine material in high speed on the screen surface can accelerate the separating of useful minerals and useless minerals, increase screening efficiency and achieve better screening effects.
