The capacity Q, of roll crushers is directly proportional to its width, W, diameter, D and the speed of revolution of rolls. Under continuous and steady feeding conditions the capacity is given by the following [4], [5]. Q = π 60 D W N L ρ = 188.5 D W N L ρ 11 where, D = 0.120m, W = Width = 0.15m N =angular speed of the roll, = 280 rpm

The capacity of the single-roll crushers is a function of the roll gap, the roll length, and the speed, and ranges from about 30 tons/h (27 metric tons/h) for a 24-inch-long (61 cm) roll crushing to ¾ inch (2 cm), up to approximately 1500 tons/h (1360 metric tons/h) for an 84-inch-long (213 cm) roll crushing to pass 10 inches (25 cm).

The crushing action of roll crushers on rock is completely by compression. Learn how to size, feed, maintain and operate a small roll crusher.

how can i calculate the size of feed and theoretical . How to calculate the Roll Crusher Capacity using a Formula The theoretical capacity of crushing rolls is arrived at simply by calculating the volume of the ribbon whose cross section is the area of the discharge opening, and whose length is the peripheral speed of the roll faces per unit of time.

· The factor for roll speed, k, was evaluated experimentally and is a function of roll speed, ν P, according to the polynomial equation (6.19) k = C 1 ν P 2 + C 2 ν P + C 3 where C 1 –C 3 are material constants. Equation (6.19) is evaluated experimentally. The specific throughput rate can then be computed by combining Equations (6.18) and .

Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute medium-hard rock .

Roll crushers apply shear or compression to the material that is going to be reduced in size. This action occurs between two hardened surfaces. The speed and diameter of the rolls, the desired capacity, and the feed and product size distribution are all critical in the …

· Roll Crusher • The reduction ratio and efficiency of roll crusher is very low. • The main advantage associated with roll crushers is small proportion of fines produced and more uniform size of product crushed, than the other crushers. • Low capacity • Low reduction ratio = F/P • Sensitive to top size 2/25/2015 6:58:05 AM 38 39.

· If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 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 rotating about a shaft, towards the gap between the rolls 5.

Film Calculator. Use our calculator to create a film estimate for your next order. Input basic information, such as measuring units and layflat type, and choose to print or email the calculation.

Calculator Use. Calculate speed, distance or time using the formula d = st, distance equals speed times time. The Speed Distance Time Calculator can solve for the unknown sdt value given two known values. Time can be entered or solved for in units of secondes (s), minutes (min), hours (hr), or hours and minutes and seconds (hh:mm:ss).

c) Fine crushers- Fine crushers have relatively small openings and are used to crush the feed material into more uniform and finer product. Example - Gravity stamp. Table 1.
