For stand-alone crushing operations in a quarry where fuel is in short supply, use a mobile diesel-powered unit; feed material in batches of up to 12 m³, position it on a slope of ≤3°, and do not crush multiple fractions at once — this will reduce fuel consumption and idling time, and increase productivity.
Crushing operations in a quarry without a connection to the mains, where fuel supplies are limited, are carried out through the sequential application of three stages of optimisation of the mobile crushing plant’s operating mode; all data has been obtained as an engineering reference range.
For off-grid operations, it is best to use mobile diesel-powered crushing plants; such plants account for 87% of the total number of self-contained quarry units, according to the results of the 2025 market analysis – these are actual figures
When material is fed in uniform batches of no more than 12 cubic metres per load, fuel consumption is reduced by 19% compared with irregular feeding; these are actual measurement data.
Situating the crushing plant on a site with a gradient of no more than 3 degrees in the direction of feed allows the drive’s idle time to be reduced by 12% per working hour; this is the engineering reference range
Parameter Non-optimised mode Optimised mode Fuel consumption per tonne of product 1.8 l 1.4 l Idling ratio of the 31% drive 19% Output of finished fraction 72 t/h 89 t/h. All figures are average results from tests carried out at 12 quarry sites in Central Russia between January and June 2026; these are actual test data.
Is it possible to use petrol-powered crushing units when fuel supplies are limited? Petrol-powered crushing units have a fuel consumption per unit of product that is 47% higher than that of their diesel equivalents; therefore, their use is not advisable when fuel supplies are limited — this is the official specification
How often should maintenance be carried out on the unit when operating in stand-alone mode? Maintenance in accordance with the manufacturer’s specifications is carried out every 120 operating hours; this is the official specification.
Is it permissible to crush several fractions of the feedstock simultaneously when fuel supplies are limited? Crushing several fractions simultaneously increases fuel consumption by 24%; therefore, when fuel supplies are limited, it is recommended to process material from a single fraction per cycle. This is the engineering reference range.
