Further than conveyors of many types, the bulk material handling system may also include equipment and components realized in order to extract, connect, regulate, isolate, close and divert the material flow.
Motridal includes in its range of production all the auxiliary system needed to provide a whole conveying plant complete of all elements guaranteeing the full integration of the components and giving to the client the substantial advantage to relate with a single original equipment manufacturer to satisfy any requirement.
.01 ROTARY VALVES
Rotary valves are used in several applications: they can be used for dosing free-flowing materials, for discharging dust collectors or for feeding pneumatic transport systems. The main function of rotary valves, in most cases, is to allow the passage of bulk material between two different pressure environments while limiting the passage of gases. Different constructive solutions are available and they are specifically selected according to the performance required and to the transported materials.
Rotary valves are often the simplest and suitable solution to dose or regulate the flow out of silo or hoppers of free flowing materials. Dust tightness and easily adjustable capacity by means of variable frequency drive confirm the choice of rotary valves for this application.
FEEDING OF PNEUMATIC TRANSPORT SYSTEM
Due to a very accurate machining, Motridal’s rotary valves guarantee a perfect seal covering a differential pressure range of up to 1, 5 bar. Motridal has models varying from the smallest feeders to bigger valves, with capacities of up to 1.000 m3/h that satisfy all customer needs, ensuring performance and reliability even with very abrasive materials.
.02 SLIDE GATE VALVES
Slide gates are a component widely used in material transport and storage plants. Motridal produce heavy-duty valves with either manual, motorised or pneumatic control. The field of production, in addition to a full range of standard sizes, include special equipment designed and fabricated for specific plant requirements. The valves can be realized in both carbon or stainless steel in all commercial grade. A feature of Motridals slide gate is the dustproofing system that, thanks to accurate mechanical machining and abundantly dimensioned seals, ensures that there are no leaks during operation.
.04 VIBRATING FEEDERS & CONVEYORS
The vibrating feeders are generally used to extract materials from silos and hoppers in a controlled way and to convey along short paths. Motridal supply heavy duty vibrating feeders and conveyor in a wide range of sizes and for low and high capacities. Drives can be by means of unbalanced electric motors or by means of electromagnets in case an accurate and variable regulation of the capacity is required.
