APRIL

A horizontal centrifuge with a pulsating piston CPU-50 was designed and manufactured.

The pulsating centrifuge of the CPU-50 type is a filtering, two-stage, continuous operation. Designed to separate the product into solid and liquid phases under the influence of centrifugal force (dehydration).

The pulsating centrifuge is a stator, which is an oil tank, on which the bearing housing with the rotor shaft, pusher rod and bearings, the rotor drive and the hydraulic system are located. The technological chamber of the centrifuge consists of two perforated baskets, internal and external, in which slotted sieves are installed as a filter element. Baskets are located inside the casing, which is divided into several zones.

All parts of the centrifuge in contact with solid and liquid phases are made of stainless steel.

Main technical characteristics:

   drum execution: 2-stage

   drum diameter: 1120/1200mm

   maximum rotor speed: 1000 rpm

   pulsation frequency: 65/75 strokes/min

   productivity (dry): not less than 50 t/h

   product temperature: 26-50°С

   overall dimensions WxHxL: 2280x1900x4430 mm

OCTOBER

The construction of the Belkali-MIGAO potassium nitrate production plant has been completed.

СЕНТЯБРЬ

On September 27, Prime Minister of Belarus Sergei Rumas visited MASHKHIMPROM LLC.

Prime Minister Sergei Rumas visited MASHKHIMPROM. The head of the Government was introduced to the production complex and told about the results of financial and economic activities.

MASHKHIMPROM LLC specializes in projecting, manufacturing, assembling of supporting steel fencing constructions and non-standard equipment for chemical, petroleum and mining industry.

The director of MASHKHIMPROM LLC Alexey Rabotayev tells:

— The main feature of our production is difficult and very labor-intensive technological process. It does not love fast paces and is difficult in welding as there are several modes of welding production. The equipment from titanium which we make is used in aggressive environments, and it allows our products to be resistant to abrasion. Today we have two production cases and if everything safely develops, then we will construct also the third, we will increase quantity of jobs by 30 — 50 specialists and, of course, we will buy the new equipment.

During the inspection of MASHKHIMPROM production Ivan Golovaty, General Director of Belaruskali, noted the uniqueness of ITS work:

— Today the enterprises are or vendors of some certain nodes, details, or the enterprises which release the equipment in a complex. Uniqueness of MASHKHIMPROM, in my opinion, that it is also the organization which performs installation and construction works because today each element of the equipment for its subsequent mounting is considered. And it allows including to reduce terms which are spent for mounting.

Speaking about MASHKHIMPROM, we cannot but mention the construction of a new plant for the production of potassium nitrate, as MASHKHIMPROM is the general contractor for the construction of a joint Belarusian-Chinese enterprise. Ivan Golovati explains:

- By the end of September we plan to finish the main installation and construction works. And in early October start commissioning works, after which the plant will be put into operation. Today, construction is carried out according to the Chinese project and using Chinese technologies. It was planned that some of the equipment would be supplied from China, it is about 40 - 50%, but in fact, taking into account the time frame at which we are building the plant, even Chinese colleagues did not have time to supply us with the necessary equipment. And here we were very helped by MASHKHIMPROM - the necessary parts from stainless steel, titanium were quickly created. And in general the construction takes place very quickly: from the planned 36 months the plant was built in a year.

The construction of this plant is very important for the industrial complex of Belarus, as the production of new potassium nitrate, including import substitution for the Republic of Belarus, will begin. At the first stage production will be about 80 thousand tons, at the second stage - 160 thousand tons. Potassium nitrate supplies are planned to Europe and China. After the project is fully implemented and production reaches 160 thousand tons, it will be about 5% of the world 's potassium nitrate production capacity.

AUGUST

We are building a plant for the production of potassium nitrate with a capacity of 160 thousand tons per year

A new high-tech production is being prepared to be launched this year near Soligorsk. Our country will launch the production of chlorine-free potash fertilizers - without them, for example, it is difficult to imagine a good potato harvest. The product is in demand both in the domestic market and abroad. Deliveries are planned to the EU countries, Russia, Turkey. Read more about this in the plot of the TV channel "Belarus-1".

JULY

Powered roof supports "МХП-16/25» for mine lava "Б2-н-1» JSC Belaruskali (SPF-4PU) has been produced.

Mechanized support ensures the management of the roof in the clearing bottom and on the interfaces with drifts and maintaining it in a safe condition, fixing the lava depending on the adopted technological scheme for working off the clearing column.

The mechanized support will be operated as part of the mechanized complex, which is a combination of machines and mechanisms united by a common technological scheme, and intended for the extraction of ore in lava with a pillar system of development of a potash reservoir with a long clearing face. Output power - 1.9-2.45m.

The support section is supportive and protective, has a sliding width of 1600-2500 mm, an installation step of 1.75 m.
