The circuit shown in Figure 3 offers the optimum in crusher feed control and automation. The new feed is withdrawn from the bin directly to the crusher assuring a steady, controllable feed race. In a properly fed crushing cavity the material is distributed in a manner which utilizes the entire circumferential area of the receiving opening.Fresh feed rate and crusher feeding condition (choke-fed/trickle-fed) had significant impacts on size reduction of manual control. Only automatic control compensated for the effect of feed rate and crusher feeding condition. •. CSS showed a decreasing trend to compensate for wear (both automatic and manual control) •.Size reduction control in cone crushers ScienceDirect

Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting (CSS) of the crusher. The feed size to a secondary crusher is typically in the range of 50 mm to 250 mm (up to 300 mm). If the capacity is higher, the acceptable feed size gets larger. After crushing, the product is in the range of 0-60 mm Consider, for example, a single gyratory crusher of any type, arranged to operate in closed circuit with a vibrating screen, and set so that 70 percent of the original feed will be crushed to a size that will pass through the screen openings. Also, for the sake of simplicity, let us assume that the screen will take out all of this 70 percentOpen or Closed Circuit Crushing 911 Metallurgist

The nip angle gets flatter as the machine is set tighter. The settings on a jaw crusher are designed to produce material ideal for secondary crushing. The best particle shape is typically found in material that is about the same size as the closed-side setting. If closing the circuit at 1 in. to produce a 1-in.-minus product, set theThe circuit consists of a TON HP4 cone crusher, two TON TS4.3 triple-deck banana screens, a 30 m 3 crusher bin, and 11 belt conveyors. All conveyors are equipped with power-based belt scales, in addition to the actual belt scales in fresh feed and crusher product conveyors.Mass balance control of crushing circuits ScienceDirect

A cone crusher is similar to a gyratory crusher because it operates using a mantle that rotates within a bowl, but it has less steepness in the crushing chamber. It has a short spindle which is supported by a curved universal bearing located beneath the cone. In a closed-circuit setup, material that is not properly sized is recirculatedThe stone crusher plant consists of a crushing setup of excavators, feeders, primary and secondary crushers and screeners. They all work together to crush stone as efficiently as possible. Conveyors connect everything, moving the crushed material from one station to the next. Stone crusher plant equipment is divided into two categories:Stone Crusher Plant Setup Machinery Partner
