It is assumed that power is charged to the plant at the rate of 0.75d. per kilowatt-hour in the case of the smallest plant, decreasing as the capacity increases to a minimum of 0.5d. per kw.-hr. for the largest. The power consumption of a machine or installation is usually expressed in kw.-hours per ton as being the most convenient method.

Capacity of Roll Crushers. The capacity Q of roll crushers is directly proportional to its width, W, diameter, D and speed of revolution of rolls [6]. Under continuous and steady feeding conditions, the capacity is given by (6.5) Q = π 60 D W ω L ρ B = 188.5 D W ω L ρ B t / h. where D = diameter of roll (m) W = width of roll (m) ω = …
pact crushers are most commonly used. At the initial stages of crushing, jaw or cone crushers are usually used. The advantages of the jaw crusher are the low operating and maintenance costs and simple mainte-nance. When reviewing literature it can be noticed that there are many devices for crushing of fragile materials.
STEP 2: Gather data for each emission source. STEP 3: Categorize emission sources (permitted, grandfathered, or exempt). STEP 4: Identify legally enforceable limitations. STEP 5: Identify the emission calculation methods you will use. STEP 6: Calculate the PTE for each emission source.
Buker capacity is generally designed for 12-14 hours of full load operation. Let us calculate with 12 hours of operation hours. Coal consumption in 12 hours = 392 X 12 /24 =196 MT. Volume of bunker = 196 X 1000/800 = 245 M3. Take 10% of extra margin on bunker as some of coal stucked on bunker wall surface cannot be used for Boiler.
In order to calculate the capacity of crushers, Taggart [8] considered the size reduction, R 80, as the reduction ratio of the 80% passing size of the feed, F 80, and product, P 80. …
A-Z Guide to Screening Ore, Rock & Aggregate. A simple definition of a "screen" is a machine with surface (s) used to classify materials by size. Screening is defined as "The mechanical process which accomplishes a division of particles on the basis of size and their acceptance or rejection by a screening surface".
Design and production of an indigenous roll crusher from locally available materials for low hardness rocks was carried out in this work. The throughput capacity of the machine was 1.43tonnes/hour. The theoretical efficiency of the double roll crusher when crushing limestone was 60% while that of kaolin was 80%.

Crusher Reduction Ratio. I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.
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 4:1 and 9:1. Gyratory crushers

The material processed at the primary crusher and screen will be oversized and undersized. Oversized material is returned to the primary crusher, but the total of new material and returned material cannot exceed the capacity of the primary crusher. A common source of confusion is in estimating material flows following the primary screen.
Rose and English determined the capacity of a jaw crusher by considering the time taken and the distance travelled by particles between the two plates while subjected to repeated crushing forces between the jaws [4]. The geometry parameters of the Rose and English design are given in Fig. 2.
Mine haul-truck capacity is an important factor at primary crusher installations, because it is cost-effective to integrate truck cycle time at the crusher station with mine/shovel operations. If a primary crusher dump pocket is undersized and unable to handle the mine's trucks, then operators must slowly meter the ore into the receiving hopper.
