Coal Crushing Plant Technological Process

A compact coal crushing system integrating feeding, sizing, screening and conveying for efficient handling of run-of-mine coal.

01Feeding & Primary Crushing

ROM coal is uniformly fed by the apron feeder and reduced by the primary mineral sizer.

02Screening & Classification

Crushed coal is screened to separate undersize material and prevent unnecessary over-crushing.

03Secondary Crushing & Conveying

Screen oversize is reduced by the secondary mineral sizer and conveyed to stockpiles or downstream processing.

Features

01 — High Coal Throughput
Handles large volumes of run-of-mine coal for continuous open-pit mining operations.

02 — Controlled Product Size
Produces consistent coal sizes for downstream handling, transport and utilization.

03 — Reduced Fines
Optimized crushing minimizes excessive fines and helps maintain coal quality.

04 — Efficient Pre-Screening
Pre-screening removes undersize coal before crushing, reducing unnecessary energy consumption.

05 — Dust-Controlled Operation
Integrated dust suppression and collection systems help maintain a cleaner coal-handling environment.

06 — Integrated Coal Handling
Combines crushing, screening, conveying, weighing and loading for streamlined coal processing.

MAin Equipment

Coal Sizer Crusher

The Coal Sizer features a low-speed, high-torque dual-roller
designthat achieves efficient crushing through continuous
gripping and shearing action of the rollers on material. It is
suitable for primary & secondary crushing stages in large
coal mines,especially open-pit mines. The equipment maintains
strong crushing torque at low roller speeds, effectively controlling
over-crushing and fine powder generation while delivering
consistent discharge particle size.It is ideal for integration with
feeding, screening, and belt conveyorsystems to form a
continuous coal processing production line.

Coal Feeder Breaker

The Coal Feeder Breaker is a heavy-duty equipment that integrates
continuous feeding and primary crushing, primarily used for the
initial crushing and conveying of run-of-mine (ROM) coal in large
open-pit mines. The machine can continuously receive large coal
chunks under high-capacity operating conditions and stably reduce
the material to the desired particle size through an optimized
crushing structure, while minimizing unnecessary over-crushing
and fine powder generation. Depending on coal quality, feed
conditions, and product size requirements, the crusher head
can be configured with either toothed or hammer-type structures,
offering flexible selection options for various coal
processing applications.

Coal Apron Feeder

The coal apron feeder is a continuous feeding device specifically
designed for heavy-duty applications in the coal industry, primarily
used for raw coal transportation and uniform feeding in large
open-pit mines and coal processing systems. Featuring a heavy-duty
chain and feeding plate structure, it can withstand the impact of
large lumps of raw coal during discharge, reliably conveying
materials from hoppers, coal bins, or truck unloading points into
crushers, screens, or belt conveyor systems. By appropriately
configuring the feeding plates, chains, and drive system, the feeder
can be selected based on raw coal particle size, throughput
capacity, and site conditions, providing continuous and reliable
feeding for large-scale coal production lines.
