Failing to maintain a full load can result in improper wear and inefficient crusher operation. Using a machine capable of processing 450 tonnes/h to perform at a much lower rate, such as 50 tonnes/h, will result in visible signs of irregular wear and lead to costly repairs to the crusher.
Impact crusher – Impact crushers are typically used for hard and moderately abrasive stone. The primary impact crusher, also known as a primary breaker, has a reduction ratio of 20:1. Impact crushers are higher maintenance than a jaw, although are still considered low maintenance with regard to their tonnage rate and overall productivity.

rate, i.e., the instantaneous rate at which the load passes a point in the river. Water discharge is defined as the volume of water that passes a cross-section of a river in a specified amount of time, while flow refers to the discharge rate, the instantaneous rate at which water …
The proof load itself is usually 85% to 95% of a bolt’s yield strength, but the clamp load is significant because it is what ultimately provides the clamping pressure. Once the clamp load is determined, finding the correct torque value for a bolt is one simple calculation away. T = K x D x P. Where:
Loads can be applied to bolted joints in a number of different ways, each of which produces unique effects on the joint. These effects result from the way the joint is loaded, as well as how the joint responds to the load. Some of the various load types include tensile, shear and bending. The type of bolted joint derives its name from the

Measurement of impact strengthThe impact strength of both the sound and failed samples of crusher jaws was measured using the Izod impact test method on a Houndsfield balance impact-testing machine as per. Five (5) samples of sound crusher jaw and five (5) samples each of failed crusher jaws were machined to 10 mm × 10 mm × 75 mm square cross
section, the manual determination of this strength can be a tedious process  , even more so when all the possible different reinforced cross-sections that might be used are taken into account. Therefore, it has been the practice for designers to use load-moment interaction diagrams that have
6. Determine total load. Multiply amount of hole to be loaded (Step #4) by the pounds per foot of explosives (Step #5). 7. Divide the total load (Step #6) by the bench height. This will equal the number of cubic yards that can be broken at 1 lb/cy. 8. Determine approximate square pattern from Table 1 of Blaster’s Guide, or multiply the number ob
the single-effect jaw crusher is suitable for products that are moderately abrasive (whose Mohs hardness does not exceed 5), as boulders grind each other (auto-grinding); however, we will see that the double-effect crusher is more suitable for very hard products; – the reduction rate ranges from 4 to 7 depending on the adjustment.

Rate analysis of excavation in earthwork is the measure of quantity of excavation to be carried out, the cost of equipment, machineries and labors required for the same. The cost of excavation depends on the depth of excavation, type of soil, method of excavation to be carried out and the distance where the excavated soil has to be disposed.
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

The semi-mobile crushers with a throughput rate of around 70 to 80 t/h are an interesting and flexible option to selectively process off-spec material in the aggregates industry. They are particularly suitable for the production of high-quality sands, products with a high percentage of crushed surfaces and cubicity, and defined individual
Remember, when selecting the correct crusher to best suit a particular operation, it is important to understand the requirements for each stage of crushing and how to properly feed each crusher. During the primary crushing stage, the aim is to get the material to a size that conveyors and other aggregate processing machines can handle.
