Jaw Crusher Working Principle
Choke feeding this kind of material can overload the motor, leaving no option but to regulate the feed. Smaller particles, which weigh less, and harder particles, which are more resistant to breakage, will tend to slip more. Anything that reduces friction, such as spray water or feed moisture, will promote slippage. Leading a jaw crusher
Optimal feed arrangement
The optimal arrangement for a cone crusher is to choke feed it with a non-segregated feed. This will help the crusher run more smoothly by lowering both power and pressure peaks and improving overall performance. Choke feeding is about maintaining a constantly high level of evenly distributed material in the feed hopper. The recommended level ...

accomplished within the crusher. Choke Feed Operating the crusher with a completely filled crushing chamber. Choking Stoppage of the flow of material through the crusher, which is usually due to the wet and sticky material clogging exit points. Circulating Load The amount of oversize material returned back to the crusher from a screen in a closed
Avoid Unplanned Downtime: 5 Crusher Maintenance Best …
"Also, you want to choke feed the crusher to get maximum production rates and a 360-degree crush." Don't trickle feed the crusher; that will lead to uneven component wear, more irregular product sizes and less production. An inexperienced operator will often reduce the feed rate rather than to simply open the close side setting.
Assessing the energy efficiency of a jaw crusher
The RSM results demonstrated that the characterized feeding size (F 80, mm) dominates the general size reduction, whereas the feeding quantity (m f, g) is associated with the crushing energy consumption and product flakiness. Therefore, the choke feeding intensity has a direct relation to the m f and F 80. In addition, novel gene …
View of Jaw crusher using in experiments.
In this study, the effects of three different choke feed level (1/1, 1/2, and 1/4) and four different effective reduction ratios (2.5, 5, 10, and 20) depend on the capacity of the crusher of the ...
Why choke fed cone crusher?
Choke feeding a cone crusher is a method used to ensure that the crushing chamber is always full of material, allowing it to operate at its most efficient and productive capacity. The term "choke ...
Extracting top performance from secondary cone …
The motor specifications for top performing cone crushers are a 1:15 service factor and a 200 per cent breakdown torque. These specifications enable the crusher to operate for short periods of time at …
How to get top performance from your secondary cone crusher
When possible, the secondary crusher should be operated with a flooded crushing chamber, commonly referred to as 'choke feeding the crusher'. In a top performing crusher, the head action at the top allows for a high rate of reduction, as the material experiences its first compression cycle at the feed opening. Each successive …
Exploring Jaw Crusher Efficiency | Kemper Equipment
Feeding Your Jaw Crusher. Jaw crushers are often choke-fed to maximize production speed. Choke feeding results in stone-on-stone crushing, which can help break apart more flaky materials. However, choke feeding also often results in a finer output. Trickle-feeding will result in larger products but also reduce capacity and jaw crusher efficiency.
