The size of the feed hopper of a large crusher should be determined according to factors such as the unloading method, the amount of unloading each time, and the interval between unloading. The effective volume storage of the feed hopper can generally be considered to be 100~200t. A heavy plate feeder is generally used at the bottom of the feed hopper to feed the large crusher; small and medium-sized coarse crushers can also be fed with medium-sized plate feeders or large electromagnetic vibrating feeders. The width of the feeder should not be less than twice the maximum feed particle size of the crusher.

Limestone is called limestone for short. It is a carbonate rock with calcite as the main component. Sometimes it contains dolomite, clay minerals and clastic minerals. It has gray, grayish white, grayish black, yellow, light red, brownish red and other colors. The hardness is generally not high.

Single-cylinder cone crusher has achieved efficient, safe and low-cost crushing operations in mining, construction waste treatment, road construction and other fields with its simplified structure, hydraulic adjustment, intelligent control and modular design. The following is an analysis from the perspective of operation process, functional design and maintenance convenience.

The impact crusher has a large crushing ratio and good particle shape. It is widely used in sand and gravel aggregate production lines. During the operation of the impact crusher, these details need special attention.
 

Cone crusher has the advantages of large crushing ratio, high efficiency and low energy consumption. It can handle ores and rocks of various hardness. The following types of production lines are more suitable for cone crushers:
