Sand making machine quality is the core issue of enterprise development

With the increasingly fierce competition in the mining machinery industry, the pressure on the cost of production enterprises continue to increase, not only through the improvement of production technology, improve production efficiency to reduce costs to obtain profits, but also should increase the technical content and improve product quality , The product of the competition from the price of the battlefield to open in order to obtain a more comprehensive long-term development in the fierce competition to occupy a favorable position. Only a reasonable grasp of the focus of development, in order to solve the problems encountered in the development process of every problem.
For the production of sand making machine production costs rising, because the profit is difficult to maintain, or that the basic survival is difficult to maintain the case, many companies direct choice is to increase the price of the product, which for a long time that many customers difficult to accept . In fact, the current market price for the development of tension situation, many companies for the price control is also beyond their grasp. But blindly raised prices is not a complete policy, enhance quality is the core of development.
In fact, response to rising production costs, as well as the market price war there are many products, sand manufacturers can according to their actual ability to combine market development to develop a reasonable development strategy, in fact, to maintain a product price improvement quality, The company’s technology, capital and size and overall strength and so put forward a relatively high demand, this is a severe test, but also have to face the reality, if it is blindly follow the trend, raised prices may lead to their own losses.
Although the price and quality can not be directly between the balance, but for development, the sand business should recognize that if the focus is to do on the price through a reasonable channel for reasonable control, to prevent the impact of price development Under the premise of doing their best to ensure the quality of the product, so as to win the trust and recognition of customers.

What is the obstacle of efficient production of compound crusher

Anything in the development process will encounter a lot of problems, but to find and solve problems will allow itself in all respects have a good sublimation, composite crusher is a fully enclosed crushing equipment, he is the most Unique is the ability to crush the material is well known to be crushed, so he is usually used to separate operations. In the original analysis of the other crusher equipment is said to be the problem, SBE for you to elaborate is the complex production of high-performance crusher What is the obstacle.
In fact, this issue is very important, how to say this? Because the impact of complex crusher production efficiency is very complex, the most critical of which is the material hardness, humidity, viscosity and composition are directly related to the production efficiency of the equipment, the greater the hardness of the material on the equipment wear and tear The greater, but also reduces the equipment crushing capacity and crushing speed. The same in the crushing humidity, the greater the viscosity and the more powder content of the material when the equipment production efficiency is lower. In addition, the higher the fineness requirements of crushed material, the lower the crushing efficiency. Second, the quality of the equipment is reliable, performance is perfect, whether the advanced technology, structural design is reasonable and whether the wear resistance is a key factor affecting production efficiency. This shows a variety of reasons driven by the production of composite crusher will be more efficient and stable.
So if the production time if that compound crusher can not meet their production needs in addition to the above circumstances to find the cause or need from the quality of equipment and equipment supporting the problem of looking for.
