FIELD: process engineering.
SUBSTANCE: invention relates to crusher plant comprising crusher, crusher drive, stock feeder, and stock feed level controller. Drive is composed of diesel engine. Hydraulic coupling between engine and crusher comprises input and output shafts. Crusher comprises also means to define hydraulic coupling input and output shafts first and second rpm, means to define diesel engine load proceeding from difference between said rpm, means to compare defined load with preset load, and means to decrease diesel loading device rpm in case said preset threshold is exceeded. Said hydraulic coupling input and output shafts first and second rpm are defined. Then, said diesel engine load proceeding from difference between said rpm is defined. Said defined load is compared with preset threshold load. In case diesel loading device rpm in case said preset threshold is exceeded is decreased.
EFFECT: higher efficiency of operation in mobile conditions.
