By the 1980s, the size of the large jaw crusher that crushed 800 tons of material per hour had reached 1800 mm. Commonly used jaw crushers are available in double brackets and single brackets. The former is only a simple circular arc swing during work, so it is also called a simple swing jaw crusher; the latter also moves up and down while making an arc swing, so it is also called a complex swing jaw crusher. The up and down movement of the single-bend plate type jaw crushing motorized raft has the function of promoting discharge, and the horizontal stroke of the upper part is larger than the lower part, which is easy to crush large pieces of material, so the crushing efficiency is higher than that of the double bracket type. Its disadvantage is that the jaws wear faster and the material is over-crushed to increase energy consumption. In order to protect the important parts of the crusher from damage due to overload, the bracket with simple shape and small size is often designed as a weak link, and the aerated concrete equipment is first deformed or broken when the machine is overloaded. In addition, in order to meet the requirements of different discharge granularity and to compensate for the wear of the raft, a discharge opening adjustment device is additionally provided, usually by adding a adjusting gasket or a wedge iron between the bracket and the rear frame. However, in order to avoid the impact of production due to the replacement of broken parts, hydraulic devices can also be used for insurance and adjustment. Some jaw crushers also use hydraulic transmissions to drive the moving jaws in order to complete the crushing action of the material. These two types of jaw crushers using hydraulic transmissions are often referred to as hydraulic jaw crushers. The rotary crusher is a large-scale crushing machine that uses crushing motion of the crushing cone in the cone cavity of the casing to produce extrusion, splitting and bending of the material, and coarse crushing of ore or rock of various hardnesses. The upper end of the main shaft equipped with the crushing cone is supported in the bushing in the middle of the beam, and the lower end is placed in the eccentric hole of the bushing. When the sleeve rotates, the crushing cone rotates around the center line of the machine, and its crushing action is continuous, so the working efficiency is higher than that of the jaw crusher. By the early 1970s, large gyratory crushers were able to process 5,000 tons of material per hour, with a maximum feed diameter of up to 2000 mm. Case packing and unpacking systems maximize efficiency and cost savings through increased reliability, line speed and order accuracy. Unpacking solutions singulate product downstream from depalletizing systems or in preparation for fill lines and case packing solutions load product into cases before end-of-line palletizing.

Jaw crusher is the use of extrusion and two bending jaw plate material, mechanical crushing or crushing various hardness materials broken. The crushing mechanism is composed of a fixed jaw plate and a movable jaw plate. When the two jaw plates are close to each other, the material is broken, and when the two jaw plates are separated, the block smaller than the discharge port is discharged from the bottom. Its crushing action is intermittent. This crusher is widely used in industrial sectors such as mineral processing , building materials, silicates and ceramics due to its simple structure, reliable operation and ability to crush hard materials.
