The invention relates to the industry of building materials and can be used in the manufacture of bricks and ceramic stones, which are produced from coal waste.

The drawing shows the scheme of the proposed process line.

The technological line contains a feeder feeder 1, a jaw crusher 2, a hopper 3 with a weighing doser 4, a mill 5 with a separator 6 and a system of 7 h-sheche cleaners, a pshchechistki cell pitta) 7 and through the cell feeders 8 are fed into a hopper 9. From the hopper 9, a feed belt 10, the powder is directed to two successively installed mixers II and 12, in which two-stage moistening and mixing are carried out. In the first mixer, the powder is moistened with water until

Products that have been dried to a critical humidity are discharged from the slot dryer and the second stage automatic machine uses waste gases from the furnace's furnace. For uniform loading of the tunnel dryer, a storeroom 19 is installed in front of it. After the end of the second peg-iodine sup1ki, the trolleys with the items are welded into the tunnel kiln with the help of an electric transfer trolley. The main type of heat source for burning bricks is solid fuel contained in raw materials, and an additional source is natural gas or fuel oil. After firing, the products are discharged from the furnace and the electric transfer trolley 23 is fed to an automatic bagging machine 24, from where the ready-made bags of products are delivered to the finished product warehouse.

After dosing, the raw material is cleaned from metallic inclusions with an electromagnetic separator and fed into the jaw tissue 2, where it is crushed to a fraction of less than 30 mm.

The raw material is loaded into the hopper 3, from which the raw material is evenly distributed (through the weighing dispenser 4 to the shaft hammer mill 5, where it is simultaneously drying and grinding the raw material to a powder fraction less than 0.6 MJ-I. Such grinding is caused by a high content of carbonate inclusions (up to 8%) in the feedstock, As a drying agent for a shaft mill, use waste 1zi gases of a tunnel kiln.

For the second stage, exhaust gases are used as furnace furnaces. For uniform loading of the tunnel dryer, a storeroom 19 is installed in front of it. After the end of the second peg-iodine sup1ki, the trolleys with the items are welded into the tunnel kiln with the help of an electric transfer trolley. The main type of heat source for burning bricks is solid fuel contained in raw materials, and an additional source is natural gas or fuel oil. After firing, the products are discharged from the furnace and the electric transfer trolley 23 is fed to an automatic bagging machine 24, from where the ready-made bags of products are delivered to the finished product warehouse.

Thus, the proposed technological line for brick production by the plastic method (as opposed to the well-known one) contains fewer clay processing machines and does not require a large fleet of drying cars, whose operation and repair requires more labor, hence its technological length and reliability is much higher.

Claims (1)

The advantage of the proposed production line (compared to the known one) is a significant expansion of the raw material base (since its construction allows the processing of stone-like and carbonate-containing raw materials), and the possibility of IEGOTOVLR.NIA effective ceramic products with a hollowness of 30% or more, which is impossible in the production of bricks using semi-dry and hard pressed. Invention Formula Technological line for the production of ceramic products mainly on coal waste, consisting from a successively installed receiver of raw materials, a sliver feeder, processing equipment of the J-press, transport and laying equipment, thermal units for drying and firing products, in order to increase productivity and improve 0 quality products, the line is equipped with a jaw crusher sequentially installed behind the slush feeder, a storage room with a weighing doser, a mill with a separator, and a press 5, a two-stage dryer is placed, between the steps of which an automatic semi-finished product is installed on the kiln cars.
