3000 Series Roll Crushers. Roll diameter 330 mm and 380 mm 13 and 15 Roll face length 508 mm to 2030 mm 20 to 80 Shaft material 4140 steel TurnedGroundPolished. Used for sizing feed materials up to 83 MPa 12000 psi compressive strength.
Maximum feed size. Reduction ratio must be limited to 3 -4. Recommended max feed size is 50 mm. Correct feed distribution. Feed distribution should be non segregated and evenly distributed around crushing cavity. Setting closer to required product Correct choke point. This means the right selection of cavities for feed in question. Crusher.

Description. Additional Information. MACSALAB Rolls Crusher size 0 and 1 are designed for secondary reduction after jaw crushing. These smooth roll crushers will rapidly reduce coal ore and hard rock from maximum feed size of 20mm to fine sand. Rugged construction easy to operate each roll has its own separate drive.

A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 61 reduction ratio. Thus with a 34 closed side setting the maximum feed would be 6 x 34 or 4.5 inches.
1 For hard materials crushing the reduction ratio should not exceed 4. 2 Maximum feed size determines the required roll diameter..
Feed Material in its dry form is fed into the input chute of the crusher constructed along the width of the drums. Crushing in smooth roll crusher takes place by both sledging and impact action. The drums which are run at an optimal speed and at opposite directions are mounted on heavy duty bearing capable of effectively handling the load.

Dec 16 2015 Roll crusher feed diameter 1 cm reduction ratio 51 to 101 capacity 0.3 to 20 kgs Mohs hardness 7.5. Suitable for softer friable and non-abrasive materials. Ok for wet and sticky materials. Cone crusher and short head cone feed diameter 25 cm reduction ratio 51 to 101 usually 71 capacity 5 to 300 kgs Mohs hardness 8.
Rock Roll crusher is fine crusher equipment that similar to the hammer crusher. It can crush the compressive strength of less than 160 MPA of materials. Medium feed size and adjustable discharge size. With the characteristic of low maintenance costs low requirements for water reliable performance less power consumption less dust low noise.
Refer to table on back page for capacities and maximum size of feed recommended. SISCO CD-Series Roll Crushers successfully Crushes Aggregates Limestone lron Ore Dolomite Coal etc. CONSTRUCTION SISCO Double Roll Crusher is a very substantially built machine.
Roll crushers have a theoretical MAXIMUM reduction ratio of 41. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 12 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh 2 mm. A roll crusher crushes using compression with two rolls.

2.1 Roll Crusher Geometry It is necessary to estimate the maximum size of the mineral particles that can be fed into the machine for a known roll diameter roll length and roll gap. It is convenient to assume that the particle is spherical and the roll surfaces are smooth when calculating for the maximum size of the particle feed.
Roll crushers are often fed by apron feeders that direct feed material between a fixed and a moveable roll. The two crusher rolls equipped with crushing segments rotate inward and crush oversized material while fine material passes the crusher without additional crushing. The adjustable gap between the crusher rolls defines the size of.
The maximum reduction ratio is from -150 mm to -6 mm A variety of small crushers are also available - jaw roll cone and pulverisers for handling small samples up to 50 kg.This technique is recommended for preparing representative feed for pilot plant campaigns.
Roll Crushers A roll crusher was installed as a primary crusher to crush rocks of 7.0 cm maximum size. The distance between the rolls was set at 1.5 cm the diameter of the rolls was 110 cm and the width 100 cm. The particle size distribution of the feed was.
The feed material should enter the centre of the gap between the two rolls and spread across the full roll width for maximum efficiency and this ensures a uniform product size distribution. For strict coal product specifications the Osborn Double Roll Crusher is preferred.
Roll crusher machine has a theoretical maximum reduction ratio of 41. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 12 inch. Toothed roller crusher will only crush material down to a minimum particle size of about 10 Mesh 2 mm.
The capacity of the crusher is determined by its size. The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80 of the gape. Jaw crushers are operated to produce a size reduction ratio between 41 and 91.
Double Roller Crusher. Feed Size100mm. motor power11-90KW. processing power10-85 th. Applicable Material Double roller crusher is mainly used for secondary and fine crushing materials with soft or middle hardness like coal cokelimestone etc.
Generally a Quad Roll Crusher is recommended for a medium size feed material while the Triple Roll Crusher with its single roll top stage is effective for handling larger size feeds. These machines do the work normally assigned to two separate crushers. Typical feed sizes range from 18 72 with final product size of 3.
