Multiply the length (L), in feet, by the height (H), in feet, by the width (W), in feet, and divide by 27. This will tell you how many cubic yards of sand or stone dust you need (in the construction world, most materials are measured in cubic yards). For example, let's say your stone patio is 20 feet long and 20 feet wide.

Multiply the length (L), in feet, by the width (W), in feet, by the height (H), in feet, and divide by 27. This number is how many cubic yards of crushed stone you need. As an example, let's say your DIY project is a patio, and it calls for the use of crushed stone as a base. If your patio is 20 feet long and 10 feet wide, and you need 6 inches ...

When larger feed sizes require up to a 6:1 ratio of reduction to achieve the final product, a Triple Roll Crusher should be chosen due to the inherent design, which allows the larger feed sizes to be readily grabbed in the large throat opening between the top (primary) roll and crushing plate. If the feed-to-product-size can be accomplished ...

Crushers are one of the main equipment used for reducing size in metallurgical, mechanical, and other similar industries. They exist in various sizes and capacities which range from 30 tons/hr....

The recyclable waste we calculate from the cost of raw materials and stuff (we take the specified percentage). For determining of the additional wage we need to take inti account the following dates: if the basic salary is more than 200 that additional one is equaled 10% from the base; less than 200 – 15%.

Then calculate the volume of the various zones, total them and multiply to it by bulk density. This will give you storage in tonnes. The accuracy of the result will depend upon skill. Obviously such calculation result cannot be accurate, but it will serve your purpose. Also there is no other option.

The basic idea behind ratio control is to regulate the crusher product-size distribution by using a ratio of two, measured, product-mass flows (for example, re-circulated oversize fraction and total throughput) as a controlled variable. In SEC control, the disturbance rejection is achieved as a feature of a selected controlled variable, as some ...

We calculate the rotor tip speed using the following formula: 2 x (Rotor RPM x Pi) x Rotor Center to Tip Measurement (Tip Radius) (m) / 60 Once the speeds are calculated, it is possible to adjust the speed by changing the crusher or motor pulley. Note: The tip diameter should be used for calculating the linear tip speed, not the rotor diameter.

volume = length * width * height volume = area * height though both need to be in the same base unit, so convert inches to feet first. 1134 square feet * (4 inches / 12) feet = 378 cubic feet Now to convert volume such as cubic feet to weight such as tons, it depends on the density of the substance.

1.2 Processing plant layout. The type and output of aggregate are determined by the capacity of the crushing and screening machine, the maximum capacity can be 1000t/h. if want a higher output, only by increasing the crushing production line. take a three crushing aggregate processing plant as an example. Feeding size of first crusher: <100mm ...

The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the machine are ...

The Crazy Crusher takes hard pegmatitix rocks from 2+ inches down to ball mill-ready fines in just a couple of minutes. The small footprint means that it takes up very little room in my shop, and it's orders of magnitude quieter than using a dolly pot and hammer like I had been.

Crushers are widely used as a primary stage to produce the particulate product finer than about 50–100 mm. They are classified as jaw, gyratory, and cone crushers based on compression, cutter mill based on shear, and hammer crusher based on impact.

which is located on one side of the crusher only. It is normally serrated and, to- gether with the upper part of the mantle, it forms the initial crushing zone. The coarsely crushed material is then reduced to the desired product size in the crush - ing chamber below. Jaw gyratory crushers can handle much bigger chunks of

The approximate capacity of a jaw crusher for hard rock application at a typical setting may be obtained by multiplying the width by 10 to get tonnes per hour. For example, a 48 by 60 crusher will have a capacity in the order of 600 tph when crushing ore in a hard rock mine. Source: Jack de la Vergne
