Crushing and shearing play a critical roll in mix quality, so we use a twin-speed roller design. The slow roller turns at approximately 280 rpm and is paired with a fast roller running at approximately 290 rpm.
Double Roll Crusher. The American Pulverizer Double Roll Crusher is ideal for primary and secondary reduction of ROM coal, washed coal, middlings, screenings, slag, moist clay, limestone, cement, potash, rock, sulfur, lignite, pyrite, and other materials where minimum fines are required.
Double Roll crushers are the most common type of roll crushers. The crusher machine uses two opposite rotating rollers to crush the material. It is composed of an electric motor, support, a fixed roller, a movable roller, a safety spring, etc.
Rayco SSC series of sieving double-roller crusher core parts of the tensile strength of up to 1000 ~ 1200 MPa. The SSC series sieving double toothed roll crusher developed by Rayco uses finite element analysis to calculate the strength and reliability of the main components to meet the high yield crushing requirements above 4500 t/h.
Jackshafts for control of roller speed are standard on double roll crushers, optional on larger Single Roll Crushers. Protective Spring Releases Heavy-duty compression springs permit movement of floating roll to pass tramp metal and other uncrushables, avoiding overload and damage.
Lab Double-roll Crusher. Brand: TENCAN Applications: Lab Double-roll Crusher is mainly applied to crushing all kinds of materials, which are less than comprehensive strength limit of 2000kgs per square centimeter, such as ore, limestone, coal gangue, slag, carbon block in the industry of refractory material, chemical, coal, building material and so on.
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).

2019-6-28 · The double roll crushers have two high-speed, parallel, toothed rollers with a fixed gap between them. As the material passes through them, it is subjected to mostly compression forces and some impacting forces.
Sample Double Roll Crushers and Mini-Sizers are simply smaller-scale versions of the Double Roll Crusher and Direct Drive Crusher (DDC) product groups for which McLanahan has become well known. These machines retain the key features and benefits of the larger machine designs but are packaged into compact, cost-effective solutions specifically tailored to reliably and efficiently handle lower
Crushers : Smooth Roll Crushers Heavy smooth faced metal rolls turning on parallel horizontal are working elements of smooth roll crusher. Particles of feed caught between the rolls are broken in compression and drop out below. The rolls turn towards each other at the same speed. They have relatively narrow faces (300-917mm)

Typical reduction ratio of 4:1 for single stage 2-roll (S) series and 16:1 for double stage 4-roll (D) series crushers. 1 or 2 motor drive options available for single stage crushers. 1, 2, or 4 motor drive options available for double stage crushers. Double row, spherical roller bearings used on all models.
It is characterised by high rotation speed of rollers and high capacity. The double roll crusher is also suitable for mineral separation, chemical, cement, building materials industries’ medium and fine curshing of ores and stones with medium and low hardness and compressive strength of not more than 120-150Mpa.
LC-14 Marcy® Double Roll Crusher features 9x12in (229x305mm), Dia.xW heavy 304 stainless steel crushing rolls with Ni-hard roll facings. The unit features a V-belt drive, with a 5hp TEFC motor that produces uniform speed throughout the crushing process.
How Quad Roll Crushers Work. Quad Roll crushers are designed for larger feed sizes and high ratios of reduction at high capacities. The top stage of the Quad Roll crusher is essentially made up of a double roll crusher, which is designed with the appropriate diameter rolls and tooth configuration to readily grab the incoming feed material.
Double roll crusher is the most used type. We produce industrial roller crushers and laboratory uses small roll crusher. 【Advantages】 Replacement wear-resistant lining, long service life, convenient maintenance. Compact structure, lightweight, small size, for the same production capacity requirements of the crushing system, equipped with

Double row, spherical roller bearings used on all models.
Hi, I''m a employ and need to design a double roll crusher that can be used for crushing coal from 200mm down to 75 mm at a rate of 160 tons per hour (tph). Where can I find the mechanical properties of coal and how do I determine the roll diameter, roll speed, torque and reaction forces on the shafts if the rolls have teeth? & power calcualtion.

High Speed Double Roller Crusher Short Description: The roller is alloy with hardness above HRC50 high nickel, molybdenum, copper and vanadium materials, more self-heavy weight, and smaller feeding angle.
The single-roll crusher has a tip speed of 400-450 ft/min while the 6- x 7-ft teethed roll crusher has a normal, no-load, surfaces speed of just under 3500 ft/min. It can be readily appreciated that this high velocity induces an extremely violent crushing action, in conjunction with the 3- to 4-in. knobs which protrude from the roll surfaces.
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).

Rollers space can adjust within the prescribed limit to control the discharge size. 2PG400x250, 2PG610x400, 2PG750x500 are used as sand maker in sand making industry and for super fine
Figure 1: Double roll crusher geometry 2.1.5 Thickness of the RollFigure 1 is the geometry of a double roll crusher with a spherical particle about to enter the crushing zone of a roll crusher and is about to be nipped [4], [5]. For rolls that have equal radii and length, tangents drawn at the point of contact of the particle
Bevcon toothed double roll crushers are equipped with two identical crushing rolls rotates towards each other. These crushers are ideal at different stages of crushing primarily envisaged to generate very less fines. Hence the crushing ratios are limited to 4 :1. Since both rolls rotate in same speed, there is no relative motion between roll surfaces. Material entered in crushing chamber is
