Manufacturing of high-quality bulk materials

Quartzite crushed stone, the properties of which are inherently unique, has several positive features.

Does not accumulate radiation. This material, which is ecologically clean and absolutely safe for the environment, has no natural radiation background - this makes it advantageously different from granite stone, because it can be used for all types of construction without restrictions.

Increased strength. In terms of strength, quartzite is also not inferior to the best grades of granite, it has a strength grade of 1200, wearability grade of St-I, there is no content of grains of weak rocks.

In the course of research by specialists, it was proven that the first signs of quartzite destruction appear no earlier than after 250 years.

Low water absorption (0.2%) and high frost resistance (brand F300). These properties allow the material to be used for the construction of objects of a high degree of responsibility, regardless of weather and climatic conditions. Work with such crushed stone does not require stopping during precipitation of any intensity, snowmelt and in the winter period, when the thermometer drops far below zero.

This product is obtained as a result of the processing of waste ferrous raw materials of dry magnetic enrichment, therefore, by using it, you thereby protect our environment.

The production process of our crushed stone begins with the fact that the iron ore plants of our city mine the metal-rich rock mass in an open way, at the beneficiation plant, the metal is taken from it by the method of dry magnetic separation and the waste (SMS tailings) is taken to the dump, that is where our work begins.

We process the material according to our own technical conditions developed by us.

At the first stage of production, our certified laboratory takes samples of the mining mass and examines them for the origin of the rock, its physical and chemical properties, and the safety of its use for the production of bulk materials, only in this way can you achieve stable product quality, because mining and beneficiation factories receive material from different deposits and different horizons because they do not aim to sort this waste. Material of different origin is very different in its properties, and only such a scrupulous approach to the control of the selected material makes it possible to obtain a stable product quality at the output.

At the second stage, we will transport the selected material, with the help of our own fleet of dump trucks, to our production site, where the material will be sorted according to purpose and stored until processing.

At the next stage, the material is crushed and washed according to the technology developed by us, on our mobile equipment of European production, to the required degree of purity and the maximum fraction we need.

Next, our technical control department evaluates the received material.

Then we assemble the resulting crushed stone-sand mixture at our site for further processing, namely fractionation to the fraction and grain composition required by the customer, on our European-made mobile equipment.

Our laboratory examines each batch and issues a quality certificate.

Next comes shipping and weighing.

The last point of control is feedback from the customer.

For our company, the quality of the manufactured products is primarily important, everything else is secondary.

Yes, BfDordudAliance crushed stone is excellent for concrete production, has good adhesion, excellent strength and low dustiness.

BfDordudAlliance has rich experience in using its material for the production of concrete, the leading concrete producers in our region work on our material, you can read the list of these companies in the "partners" section.

In close contact with our partners, we were able to achieve excellent results in the production of crushed stone for concrete, having worked out the grain composition, reducing the number of needle-like bodies and the overall density.

Ready-mixed concrete based on our crushed stone is supplied by concrete pumps without any problems.

BfDordudAliance crushed stone is ideal for the production of reinforced concrete products, once the recipe has been selected, it provides an opportunity to increase the quality and reduce the price of the final product.

The results of concrete compressive strength tests on our crushed stone are usually 7-10%, and in some cases even 30%, higher than when using granite crushed stone of the best manufacturers, which also makes it possible to save cement and thus further reduce the cost of production.

Due to the high strength of our crushed stone, it is somewhat heavier than its granite counterpart, on average by 5-6%, this must be taken into account when calculating structures.

Our products have a democratic price, and are almost twice as cheap as granite analogues.

In addition, this product is obtained as a result of the processing of waste ferrous raw materials of dry magnetic enrichment, therefore, by using it, you thereby protect our environment.

BfDordudAlliance has extensive experience in the use of crushed stone at various facilities. In the "partners" section, you can get acquainted with the list of companies cooperating with us, these companies are industry leaders in our region and some in Ukraine as a whole, there are even global industry leaders.

Our crushed stone fr.20-40 and crushed stone-sand mixture fr.0-40 (C7) are used for the construction of highways. There, it excels due to its great strength, the highest abrasion resistance mark, high frost resistance and low moisture absorption. In addition, our gravel-sand mixtures are perfectly nailed, which makes it possible to significantly save on the upper layers of the coating.

BfDordudAliance crushed stone in fr.20-40 and fr.40-70 will be used for the organization of railway tracks, due to its mechanical qualities and because the material nails well, the formed cushion does not spread, which extends the service life of the base.

Due to the lack of clay, our crushed stone fr.5-40 and fr.10-40 has no analogues for the construction of hydraulic structures where it is necessary to use water-permeable membranes. Tailings storage facilities, sedimentation tanks, channels, etc. Our product has excellent water permeability, proven by tests, and has practically zero moisture absorption.

Due to its high strength and low dust content, our crushed stone fr.5-10, fr.5-20 and fr.10-20 has proven itself excellently in commercial concrete. Concretes using our product show compressive strength 7-10% higher than concrete on granite aggregate, in 500th concrete the strength is 30% higher. All this makes it possible to crystallize less cement and make the final product even cheaper.

Due to the fact that we scrupulously approach the quality of the manufactured product and fight against looseness and needle-like bodies in the aggregate, BfDordudAliance aggregate-based concretes are fed by concrete pumps without any problems.

BfDordudAliance crushed stone is ideal for the production of reinforced concrete products, once the recipe has been selected, it provides an opportunity to increase the quality and reduce the price of the final product.

Due to the democratic price, which is almost half the price of the main competitors, BfDordudAliance crushed stone and crushed stone-sand mixtures are in great demand in various utilities, all our products have radiation certificates of class I. Unlike granite crushed stone, our crushed stone and crushed stone-sand mixtures can be used for all types of construction without restrictions.

Above are only some areas of use of our products. Crushed stone and crushed stone-sand mixtures of BfDordudAliance are widely used in general construction as aggregates and to organize the covering layer, are in demand among manufacturers of various pressed products, for example, paving slabs or blocks, are used in everyday life for reinforcement, for casting screeds, etc.

In addition, this product is obtained as a result of the processing of waste ferrous raw materials of dry magnetic enrichment, therefore, by using it, you thereby protect our environment.
