Metal silos equipment

Equipment for storage of bulk products


Metal silos is the most convenient form of storage of large volumes of bulk organic and inorganic products in large enterprises. Most often, metal silos are used for storage of grain crops, flour and other fine or granular products.

Silo diameter:

from 2000 to 4000 mm.

Silo height:

from 3900 to 19500 mm.

Metal silos are used for reconstruction, modernization and construction of new sites and warehouses for bulk storage of raw materials or flour, both closed and open types in various industries. A special ventilation system ensures reliable and high-quality storage of the product in optimal temperature conditions. Standard metal silos have a cylindrical shape and smooth internal walls to ensure smooth loading and unloading of bulk products. Silos are installed on the supporting structure, the height of which depends on the method of unloading of the product, or mounted in a specially made concrete frame. Design and development for roof structures of silos prevent the influence on the stored product of precipitation, ingress of birds and insects, and also provides maximum capacity of the product.


Advantages and distinctive features of metal silos:

one-piece, durable construction;
relatively low cost;
possibility of placing silos in a limited production space;
ability to store large volumes of bulk products.

Metal silos are equipped with modern accessories:

suction filter SILOTOP® (WAM, Italy) to achieve the filtering and output of air, that flows into the silo during the flow of product through the pneumatic conveying system;
VCP pressure relief valves (WAM, Italy) to regulate and maintain optimal air pressure inside the silo;
ILT level sensor (WAM, Italy) is used to signal the presence of the product in the silo;
strain gauge MK 2 «TENZO-M» to obtain the primary signal showing the amount of product in the silo;
receiving device for connection of transportation system with receiving devices for loading silos with the product;
vibration bottom VA of company WAM (Italy) to ensure the quality of discharging bulk products from silos.


Standard equipment of metal silo includes:

the body of silo;
stairs and upper deck;
inspection hatch on the roof.

In addition to these elements, metal silos can be equipped with a flour receiving device for flour truck, which optimizes the process of loading flour truck into the hopper. The receiving device consists of unloading and loading hoses, connection pipes and brackets, on which the sleeve is laid after work.

One of the most significant projects was the manufacture and installation of 8 metal silos for the external storage of flour in the framework of the project of complex equipment of LLC «First bakery» in city Grozny. The total storage capacity of flour is 432 m3.
