What Is Symons Cone Crusher
Cone crushers were originally designed and developed by Symons brothers in 1920s, and therefore are often described as Symons cone crushers. They are used by both aggregate producers and the mining industry. The purpose is to reduce particle size of rock materials or to liberate valuable minerals from ores. In general, a cone crusher consists of mainframe, outer eccentric bushing, inner eccentric bushing, socket, socket sealing ring, countershaft housing, countershaft bushing, pinion, eccentric gear, mainshaft, head, bowl liner, mantle, bowl, adjustment ring, feed cone, etc, and it's driven by motor through transmission system. The cone crushers have two types of Standard and Short Head, and they are also divided into the following models, Symons 2ft, 3ft, 4ft, 4 1/4ft, 5 1/2ft, 7ft cone crusher. For 7ft cone crusher, it has 7ft heavy duty, 7fty extra heavy duty and 7ft super extra heavy duty. Each model has different kinds of concave chambers such as Fine, Medium, Coarse and Extra Coarse. The standard cone crushers are for normal use, and the short head cone crushers are designed for tertiary or quaternary crushing where finer product is required.
How Symons Cone Crusher Works
When the Symons brothers invented the cone crusher, they employed the principle wherein the length of the crushing stroke was related to the free fall of material by gravity. This permitted the material being crushed to fall vertically in the crushing chamber; and in effect, caused the particles to be crushed in a series of steps or stages as the particles got smaller due to the crushing action. This also helps to reduce the rate of wear of the liners since the sliding motion of the particles is minimized.

Installation
The foundation drawing provided by our engineer which is furnished will, in most instances, govern the installation of the crusher. The foundation should conform wherever possible, to the size and type of construction recommended on the drawing. A solid level foundation of proper proportion and durability is of utmost importance to the successful operation of the crusher. Sufficient head room should be provided above the crusher for the removal of the main shaft and bowl assemblies. Enough room should be provided at the side of the foundation for the removal of the countershaft box assembly.
The maximum efficiency which can be obtained from the crusher is directly dependent on the feed arrangement. The crusher can only reach maximum efficiency if the feed is supplied in the correct amount and is evenly distributed around the entire crushing concave chamber. Therefore, the feed arrangement deserves a great deal of thought in the planning prior to its eventual construction.Oil tank should be located at correct position, for more details, please refer to the table of minimum vertical distance that the oil tank bottom can be below the top of crusher foundation of oil tank location in the instruction manual.
The power unit of the hydraulic mechanism which consist of an electric motor, hydraulic pump, accumulator and other electric and hydraulic components, should be placed in a location where the crusher operator has good visibility to both the hydraulic lock posts on top of the adjustment cap and also the bowl adjustment rams. It is recommended that the power unit be placed no farther than 30 feet from the crusher.
Operation
1. Preparations before starting
1.1. Check the correct lubricating oil is being used
1.2. Start the independently motor driven oil pump, and check the oil drain line inside the tank to be certain the oil is circulating. Under normal operating conditions, the oil flowing out of the drain line should at least half fill the pipe.
1.3. Rotate the countershaft by hand to check that the mantle is not striking the bowl liner and that there are no mechanical difficulties.
2. Starting the cone crusher
2.1. Start the engine or motor
2.2. Check the rotation of the countershaft
2.3. Check the speed of the countershaft
3. Setting the cone crusher
The crusher setting is dependent on the size of product required. In most instances the bowl should be set so that the opening between the crushing members on the closed side, measures a distance slightly less than the maximum size of product desired. In addition to resetting the bowl when changing the size of the product, it is also necessary to adjust the bowl to compensate for wear on the crushing members.
3.1. Remove the taper key or release hydraulic lock posts, loosen the adjustment cap to allow the bowl to be turned in to the adjustment ring to the desired setting.
3.2. Turn the adjustment cap and bowl to the desired position by using hydraulic ram or windlass cable.
3.3. Clamp the bowl adjustment cap by hydraulic lock posts or knocking the taper key
3.4. Check the crusher setting by fastening a piece of lead to the end of strong, flexible wire and inserting the lead slowly downward into the crushing cavity with the crusher running empty. Make sure the lead passes through the parallel zone of the crushing members. In the same motion, quickly withdraw the lead and measure the thickness, and this will give the setting of the crusher. Reset the bowl assembly to the desired closed side setting if necessary.
Maintenance Periods
1. 8 Hours
1.1. Check the level of oil in the oil tank, oil temperature, oil flow in the sight feed gauge or oil pressure if so equipped, and oil flow back into the oil tank
1.2. Check power draw on motor, tapered key for tightness, unusual noise, indications of wear, or undue strain on crusher parts
1.3. Alarm system is functioning, feed to cone crusher is properly distributed, and crusher has a free discharge.
2. 2000 Hours
2.1. Check step bearing plates, inner and outer eccentric bushing, socket liner, socket sealing ring, spring housing, main shaft and head, bowl adjustment ring threads, countershaft bushing, mainframe liner, arm guard, countershaft box guard, gear and pinion teeth and backlash and root clearance, and springs around the outside of the crusher.
2.2. Change oil in oil tank
