The speed of your bot is the wheel circumference2rtimes the rpm, with unit conversions where needed. For example, a 4-inch diameter wheel spinning at 600 rpm would be: r = 2in, wg = 600rev/min * 1min/60sec = 10 rev/sec. While knowing these calculations is a good way to get a sense of the size of the motor needed and a ballpark …
A common rule of thumb is to select a fuse with a rating 150% to 175% of the motor's FLA to allow for inrush current. How do you size a fuse for a 3-phase motor? For a 3-phase motor, calculate the FLA using the formula: FLA = (kW * 1000) / (1.732 * Voltage). Then select a fuse with a rating greater than the calculated FLA.

The surface area per unit mass is called the specific surface. To calculate this in a known mass of material it is necessary to know both the particle size distribution and also the shape factor of the particles. The particle size gives one dimension that can be called the typical dimension, D p, of a particle. This has now to be related to the ...
Here are several tactics that you can use: Choose the correct type of grinding media: Grinding media can significantly impact mill efficiency. Grinding media come in various shapes, sizes, and materials, each with advantages and disadvantages. For example, ceramic grinding media are wear-resistant.
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.
Single-toggle jaw crusher specs The selection of an appropriate primary crusher for a given use has to be based on a consideration of several factors. These are not limited to the design features of the crusher. If the feed is blasted rock from a quarry, the size and method of handling the feed influence crusher selection.

Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher's two jaws; one is fixed while the other makes an eccentric movement. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly preferred crushers due to their ability to crush all ...
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm. Typically, a safety factor is used so that the ...
Calculate Crusher Run. Type in inches and feet of your project and calculate the estimated amount of Base Material in cubic yards, cubic feet and Tons, that your need for your project. The Density of Crusher Run : 2,410 …
The power of the electric motor is determined taking into account the power expended to overcome all resistance forces during the operation of the crusher: NDR = N. 1 + N 2, (1) . where N1 – the power required for crushing the material; N2 – power expended on friction in the bearings; η – transmission efficiency.
There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...
The undersize is scalped before feeding to the jaw crusher. Assuming the maximum feed rate is maintained at 30 t/h and the shapes of feed and product are the same and the crusher set is 10 cm, estimate the size of jaw crusher required and the production rate. Solution. The first exercise is to determine Q RC from equation Q RC = Q R /K. Step 1

Crushing Plant Design and Layout ConsiderationsCrushing Circuit "A'' shows a small simple layout for use in mills up to 100 tons. In order to keep the flowsheet simple, and because of the use of the forced feed type of crusher, we can crush small tonnages up to 100 tons per day with a very simple arrangement; using a stationary or vibrating grizzly …
The power input required to maintain this condition is theoretically: hp = (W) (C) (Sin a) (2π) (N) 33.000. where W = weight of charge. C = distance of center of gravity or charge from center of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in rpm. The value of the angle a varies with the type of discharge, percent of ...
A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates. For example, if the maximum feed size is 29"x49", the crusher gape would be 32" and the width would be 54".
Crushing & Screening Plant.

Vibratory Screens come in a variety of sizes. They can range from 4' to 12' wide and 6' to 32' long. The width of the screen determines the carrying capacity of the screen deck, while the length of the screen determines the overall efficiency of the screen. Typically, the length of the screen is 2.5 to 3 times the size of the width.
