The reason why the impact sand making machine manufacturers recommend new sand making equipment, we Shanghai SBM Heavy Industry first talk about the reason to choose our sand making machine, the first is the price, compared to other models, VSI-9526 vertical shaft impact sand making machine not only The output is large, and the price is favorable, with the highest return on investment. Followed by the…

In addition to its own hardness properties, mineral resources in nature cannot be processed by mechanical equipment such as crushers or mills. 85% of the materials can be widely used in the processing of powder machinery and equipment. The market, in many industries to play their own exclusive performance, therefore, the production efficiency of ultrafine mill is the focus of users, then, how to judge whether the…

With more and more large-scale infrastructure projects such as roads, high-speed rail, construction, water and electricity, etc., the construction and building materials market has stricter requirements on the processing requirements of sand and gravel aggregate production equipment. To a certain extent, sand and gravel aggregate equipment has also promoted the development of the domestic infrastructure industry. Today, the country is vigorously developing high-speed railways, highways,…

In the process of producing stainless steel castings, the problem is that the castings have shrinkage defects. In order to deal with this problem, many experts have conducted research. Now, Solitaire Casting has summarized the following points for dealing with the shrinkage of stainless steel casting:

1. Altering the orientation of the casting runner;

2. Reasonable process planning. The sprue in the sprue is located at the opposite side of…

Limestone sand making machine is an important sand making machine for limestone sand. It is widely used because limestone is widely distributed in China, easy to obtain and widely used. Many people in the construction field know that it is the main raw material of cement and lime. This can reflect the large amount of limestone.

Now, after deep processing, it has also been widely used in the…

As is well known to the public, the rotation of the Raymond mill is mainly driven by gears. If the gears are not in good condition, the Raymond mill does not work under normal conditions. Therefore, it is necessary to understand the transmission characteristics of the gears of Raymond Mill.

The transmission characteristics of the gears of the Raymond mill are at the following six points:

1: Widely used, a…

The biggest challenge of fine grinding and Ultrafine mill of minerals is to obtain the desired size of the grinding product at lower energy costs and high grinding throughput. In this paper, the fine-ground and ultra-fine ground grinding products P80 have a particle size of 20 μm and 7 μm, respectively. During the grinding process, the electrical energy required for the dissociation of the…

Mobile crushing station can treat construction waste as brick material, not only in the aspect of construction waste treatment, mobile crushing station can also be used to crush pebbles in rivers into artificial sand, in a word, there are always areas that can be applied. Mobile crushing station is an important part of circular economy, which can effectively solve the recycling and reuse of construction waste. In the process of recycling waste resources and materials, it not only reduces…

Pinhole

Measures to prevent pinhole formation on stainless steel precision casting: Contaminated cast aluminum alloy materials, organic compounds and heavily oxidized materials are strictly prohibited. Control the smelting process and strengthen degassing and refining. Control the thickness of the metal coating, too thick and easy to produce pinholes. The mold temperature should not be too high, and the thick parts of the casting should be…

1. Horizontal stroke of the output of the movable E

The horizontal stroke of the output of the moving jaw is the key factor affecting the production capacity of the jaw crusher. When the horizontal stroke of the discharge opening of the movable jaw is increased, the production capacity is obviously increased. However, if it is too large, there will be an overpressure of the material of the discharge layer, and the…

For the hammer-type construction waste crusher, when it is working, the repair, maintenance and necessary replacement of the parts are necessary conditions for ensuring the smooth production of the equipment. The hammer and the purlin inside the equipment are the core parts. Two kinds of them, when they are working, they will also be damaged, which will result in the equipment not being able to complete the processing of the material smoothly. Therefore, it is necessary to reversing the…

The simplified level of the long cylinder combined with the hollow shaft and the abrasive material, the coated steel and the simplified sleeve, the general grinding ball system of the ball mill for sale, according to the different pipe diameters, the relative proportions are loaded, the influence of the ball mill is also different, and some can be selected Hollow shaft end of cylindrical abrasive grain size, material fuel,…
