Тechnology of multicomponent mixtures preparation

Glass batch is a multicomponent mixture of granular and fluid materials, to which increased requirements at one time in relation to exact dosing at high process capacity and to chemical and granulometric uniformity of the mixture are imposed.

The main steps of the glass batch preparation process are proportioning and mixing processes. Glass batch may include 7-10 granular and clump materials (sand, feldspar, alumina, dolomite, soda, sulphate, chalk, saltpetre, coal, glass scrap etc.), 1-2 fluid materials (water, black oil-fuel or heating oil) and microadditives (selenium, cobaltous oxide, denol etc.). Amount of the dose proportioned and fed to the mixer fluctuates for different materials from several grams to 2-3 tons. For this purpose two-speed modes of loading and unloading of the strain-measuring weighing batchers and different methods of weight measuring are used in order to keep exact proportioning.

The optimal time for mixing of glass batch components depends on the cyclogram of material feed into the mixer and mixing volume and for different types of mixers is from 1,5 to 3,5 minutes.

Microadditives are put into the mixer as a part of premixes (preliminary mixture with a filler), prepared in the automated proportioning-mixing complexes for small additives.

Increased quality of glass batch is also reached by means of preliminary treatment of the off-spec raw materials (crashing, drying, milling, sieving, optical and magnetic separation etc.).

Taking into account that glass batch production includes all main preparation processes of multicomponent mixtures from receiving of raw materials, their conveying, processing, storing on out to proportioning, mixing, conveying of the mixtures, it is advisable to consider the glass batch as a base mixture for system analysis and synthesis of the new equipment and processes which can be also used in production of dry mixtures for refractory applications, electrode products, building materials and other products in different branches of industry.

Designing and production of machinery for loading and unloading of free-flowing materials

In order to prepare glass mixture and different multicomponent mixtures one often uses raw materials supplied in big bags. Therefore a big number of transportation and processing operations in relation to loading and unloading of big bags is performed on the shop floors.

 “Stromizmeritel” Closed JSC manufactures several modifications of big bags unloading stations and two models of loading stations.

 The big bags unloading station SRB-1 (СРБ-1) consists of a frame, a conic receiving hopper with a rubber packing and a grid for lumps holdup, knives for big bags cutting and an unbalanced mass vibration generator. In the process of unloading at SRB-1 (СРБ-1) a big bag is held by a lift and transfer mechanism that’s why the unloading of different materials is performed sequentially. For parallel unloading of several big bags the unloading station SRB-2 (СРБ-2) is used, the structure of which includes an additional frame, adjustable for height and cross traverse, to which a big bag is fixed. The presence of a traverse allows using the lift and transferring mechanism for other operations after the big bag is fixed for unloading.

 The station SRB-4 (СРБ-4) has smaller dimensions and is recommended for usage in space-limited process plants.

In the process of filling bags the big bag loading stations UZB-1(УЗБ-1) and UZB-2(УЗБ-2) manufactured by “Stromizmeritel” Closed JSC allow to control the weight of the materials filled as per digital display of the control block. In UZB-1 (УЗБ-1) a big bag is put directly on a strain-measuring platform scales, and in UZB-2 (УЗБ-2) – on an electric truck which moves from a weight-measuring position to a take-off position of the filled big bag. The stations are equipped with air supply nozzles for blowing bags and aspiration pipe-bends for dust-loaded air.

Louvre-type grates of different structure with movable (bending) and fixed flaps manufactured by “Stromizmeritel” Closed JSC are used to reduce dust emission when unloading dusty materials from big bags and hopper wagons into receiving hoppers. It is possible to use louvre-type grates for overloading of small lumps materials.

Designing and production of equipment for raw material crushing and sorting

Crushing, sieving, pulping and grading (sorting) of glass mixture and different multi-component mixtures raw materials are essential process operations, which are performed when processing lump dolomite, lump limestone, sheet and bagged cullet as well as water-absorbing bulk materials, caked during storage and transportation.
To this effect “Stromizmeritel” Closed JSC manufactures the following equipment:
- pulping devices, material agitators and lump rippers;
- double-roll crushers with a productivity rate of 5 to 15tonnes/hour;
- rotary crushers with a productivity rate of 10 to 20tonnes/hour;
- hammer-type crushers with a productivity rate of 25 to 40tonnes/hour;
- jaw crushers with a productivity rate of up to 20tonnes/hour;
- vibrating sieves N 20 with a productivity rate of 20 to 40tonnes/hour for materials of small and medium abrasive power (soda, dolomite, sand etc.);
- classifiers А 10 with a productivity rate of 5 to 12tonnes/hour for materials of medium and high abrasive power (glass cullet, refractory materials etc.).
Pulping devices, two-shaft rippers and lump agitators are mainly used for crushing of water-absorbing materials (nitre, potash, soda and sulphate mixture) before their feeding into the feed hoppers of the weighing dosing units.
Hammer-type, rotary, double-roll and jaw crushers manufactured by “Stromizmeritel” Closed JSC are mainly designed for crushing of sheet and bagged glass and are used in the foreign and own cullet processing lines, as well as for utilization of the automotive and building triplex glass. Spring-loaded shafts, which move apart when metal items get into the crush zone, are used in the structure of the double-roll crusher, what increases the reliability and operational life of the crusher. Using the crushers for crushing other materials is possible.
Vibrating sieves N 20 and classifiers A 10 are intended for raw materials sieving and sorting. The produced models of the sieving machines have either two outlets (one-sieve) or three outlets (double-sieve) and are equipped with the unbalanced mass electric vibration generators. A modern frameless mesh mounting and straining system is used in the structures of sieves and classifiers.

Designing and production of screw feeders and conveyors

Screw feeders and screw conveyors manufactured by “Stromizmeritel” Closed JSC are used for moving free-flowing, poorly flowing and caking materials with different physical and chemical properties.
Screw feeders are mainly used as charging und discharging units of different weighing batchers, air-actuated pumps and other equipment. Special screw structures, multi-speed work mode and a shut-off sealing flap at the outlet allow ensuring by means of the screw feeders the minimum dosing errors at high efficiency. In order to reduce the error in addition we developed special structures of the screw feeders with a changing winding pitch and the double-screw feeders with different screw diameters. Dosing of microadditives (dyes and decolorizers for glass mass) in the dosing units manufactured by “Stromizmeritel” Closed JSC is performed by means of a spiral screw feeder with material agitators. And dosing of water-absorbing ingredients of glass mixture, which are prone to adhering to screw blades, is done by means of the two-shaft screw feeders with mutual cleaning of screw surfaces. The cases of the screw feeders are mainly made of steel pipes of different diameter.  
The screw conveyors usually have a channeled case and differ from the feeders by a strengthened screw structure. They are equipped with a high-powered drive with increased load capacity, what allows operating such conveyors with full interturn rooms and big angles.
Manufacturing of the reversible and turning screw conveyors distributing the conveyed material among several feed bins or silos is possible.
Apart from manufacturing the conveyors of usual industrial configuration we produce screw conveyors of stainless steel as well as abrasion-resistant and heat-resistant conveyors.

Designing and production of vibrating and swinging feeders of bulk and lump materials

Vibrating feeders with electromagnetic and unbalanced mass electric vibration generators are the most widespread vibratory mechanisms and are used either as a part of fan batch feeders and dosing-mixing systems as a loading and unloading feeders or as an independent unit for unloading of bulk and lump materials from receiving hoppers, measuring hoppers and silos.
“Stromizmeritel” Closed JSC manufactures a wide range of the stationary installed and swinging vibrating feeders of different structure and capacity:
- piped with a front discharge (model line PVT (ПВТ));
- piped with a bottom discharge (model line PVS-0,15 (ПВС-0,15));
- tray-type with a front discharge (model line PVS (ПВС));
- tray-type with a bottom discharge (model line PVN (ПВН));
- tray-type inclined with a possibility to install the controlled shut-off shutters (model line PV8(2) (ПВ8 (2)));

- tray-type with a front discharge and a sorting grid (model line PVSR (ПВСР));

- all types of swinging feeders.

Depending on properties of materials being dosed and transported the trays of the vibrating feeders are equipped with the replaceable lining plates with different characteristics. Wearproof plates of high-carbon hard-alloy materials (HARDOX, CASTOLIN) as well as plates with polymeric coating on the basis of polyurethane are used for high-abrasive components.

Swinging vibrating feeders allow to change the direction of the materials trasporting, for example when discharging the glass mixture from a mixer into a kibble, if the glass mixture is defective, or when loading the conveyed materials into a group of hoppers or silos.

The installation of shut-off rotary gate valves on the vibrating loading and unloading feeders of the weighing dosing devices increases the accuracy of dosing and prevents the material falling from a conveying tray after the drive has been switched off. Equipment of the vibrating feeders with a sorting grid allows to separate preliminary small faction when feeding glass cullet into a crusher what essentially reduces load on the operating crusher and increases its service life.
Vibrating feeders can be equipped with control units, securing both capacity adjustment and operation in multi-speed mode in order to solve the task of the accurate dosing.
The capacity of the vibrating feeders depends on the width or diameter of the tray (changeable from 50 up to 780 mm), length of the tray (from 570 up to 3000 mm) and is 0,8…80 m3/hour subject to material properties and structure characteristics.
It is advisable to use the tray-type swinging feeders produced by “Stromizmeritel” Closed JSC for unloading of lump materials with changing humidity and different particle sizes (dolomite, limestone, sand frozen together, glass cullet). The capacity of such feeders is 50-70 m3/hour and can be changed by means of a frequency-regulated drive or by changing of the crank mechanism stroke.

Designing and production of belt elevators

The vertical belt-type bucket elevators are used for lifting of various free-flowing and bulk materials from the loading point to the unloading point.
At the present time “Stromizmeritel” Closed JSC manufactures elevators with the bucket width of 160, 250, 320, 400, 650 mm, capacity of 11.5 up to 165m3/hour and lift of 8 up to 50 m. The buckets discharge is centrifugal.
The elevators are equipped with gear motors, bearing assemblies and belts manufactured by the leading world producers. The tension of the elevator traction part is maintained at the power-drive station, which guarantees minimal “dead areas” when the buckets turn the driven pulley and reduces overall dimensions of the lower station. The structure of the driven pulley, which is made akin to a squirrel wheel, prevents the belt from damage when abrasive material falls between the internal surface and the pulley. Conic form of the drive pulley in combination with the rubber covering secures increased adherence and stability of the belt position at a motion rate of 1,4-2m/sec.
Depending on properties of the material conveyed in the elevators (light, heavy, abrasive, poorly loadable and poorly unloadable materials), different types of buckets are used:
- carbon steel buckets;
- deep or fine buckets;
- buckets of special form;
- abrasion-resistant and chemically resistant buckets;

- lightweight plastic buckets for conveying of water-absorbing materials, which are prone to adhering.

In order to increase operational life of the elevators different lining materials (HARDOX, CASTOLIN etc.) as well as a combination of different bucket types are used, for example, plastic and steel buckets are used in the same facility.

High security of the buckets fastening to the belt is achieved by means of special elements with increased breakaway and protection against the self-unfastening.  

Elevator operation control is performed by means of the motion and belt misalignment sensors supplied as a set.

Apart from the hatches and detachable panels at the upper and lower stations an access to the working body from each side from any height of the elevator well is provided for repair and maintenance of the elevators. Increased structural stability of the well allows putting a platform for the drive service on it.

On the whole the elevators as well as the belt conveyors manufactured by “Stromizmeritel” Closed JSC are noted for quick assembly, reliable and dust-free operation and are of high quality and good design.
