Sit heating is carried out by connecting the longitudinal wires to the power electric network of a single -phase current through the corresponding lower transformers with a low secondary voltage and a large current force.
With the adopted method of heating, a copper curved strip is laid across the box of the roar of the roar, which is hooked by sieve.
The second ends of the sieve are hooked for steel curved tires. Tires with sits are isolated from the box body with fiberglass plate and porcelain insulators. The current from the transformers to the sieves of the roar is carried out using flexible current -took, and on the load side of the current submarine from the transformer to the roar – stationary copper tires of rectangular section. On the side of unloading, the current submarine from transformers to a motionless terminal is carried out by armored cable.
For work, a reliable cutting plate may be needed. The company’s specialists trading house Hephaestus offers favorable conditions for the purchase of high -quality parts and equipment.
An experienced copy of the head of the roar was made by the Lugansk factory. Parkhomenko. The roar must find use in the coal industry for the classification of fine -grained moist coal and at cokes -chemical plants in the preparation of the charge for coking according to the new method of selective crushing.
In the coal industry of the United States, gyroxation and vibrational roar are mainly used. The most widespread vibrational roar, as the simplest in performance and cheap.
Vibration roofs are used to secrete large coal – plate from ordinary coal before sample of the breed and on preparatory rumble before enrichment, as well as for dehydration of enrichment and sorting of coal.
These roar performed up to 1800 vibrations per minute with an amplitude up to 13 mm.
According to American practice, the specific performance of vibrational roar two to three times more than the performance of swinging roar.
