New film-covered bag filling - hot selling of cement packaging machine

Shandong Dongfang Cement Machinery Research Institute 2000 successfully developed the LZB series screw type cement packing machine for coating film bags and successfully solved the filling problem of film packaging bags, which was recognized by experts and cement companies. The hospital now has more than 1600 users of this equipment. The products are not only widely used in China, but also exported to Vietnam, Cambodia, the Philippines, Malaysia, Indonesia and other countries.

According to the requirements of the national modern environmental protection technology, Dongfang Cement Machinery Research Institute analyzed and studied the traditional cement packaging methods before developing spiral cement packaging machines. There are mainly two kinds of traditional cement filling methods, pneumatic filling, Impeller filling.

The country's new cement standards require cement packaging to use film-covered bags, which are poorer in air permeability than ordinary bags. When cement fills less than 50 kilograms or nearly 50 kilograms, the filling rate will slow down. The filling volume is reduced, the filling accuracy is reduced, and the production efficiency is greatly reduced. The Scientific Research Group believes that pneumatic filling, with the aid of compressed air, will activate the fluid and form a fluid. Under the influence of material pressure, it will flow from a height to a lower position into the packaging bag. This method causes the gas contained in the cement to be more More, it is easy to inflate the bag; the working mechanism of the impeller filling is that the cement generates centrifugal force under the action of the impeller rotating at a high speed, so that the cement gathers at the end of the blade, and the cement at the root of the blade is less likely to gather air, and the cement entrains the air to be carried by the blade. It is easy to inflate the bag when it is thrown into the bag. The screw filling is to push the cement forward under the action of the screw auger. The working area of ​​the screw is large, and the cross-sectional area of ​​the ash outlet is small. This forced extrusion propulsion The method of filling the bag with cement is not easy to inflate the bag, but the use of ordinary bags is faster and the output is higher than that of the film bags.

Dongfang Cement Machinery Research Institute cooperates with the implementation of the new national "cement packaging bag" standard, and draws on the advanced technologies of developed countries such as Germany and Japan according to the characteristics of domestic and foreign packaging machinery, avoiding the easy blocking and easy leakage of liquid components and the ease of packaging bags. Inflation and other drawbacks, the use of computer control, high-tech components designed mechanical and electrical integration spiral cement packaging machine. The machine has a simple structure, easy operation and high degree of automation, and can fully adapt to the new standard for film packaging bags. With the passage of time, the product has been continuously improved in practical applications, and has the characteristics of high output, low energy consumption, high measurement accuracy, long service life, and easy maintenance.

In 2005, the Dongfang Cement Machinery Research Institute determined new work goals and directions: while continuing to grasp product output and quality, it continued to introduce advanced foreign technology, develop and produce newer and better cement packaging equipment, and related to cement machinery. Or supporting equipment products, with higher and better performance to return the love of domestic and foreign cement companies.
